July 23, 2015 - Poultry industry representatives had an opportunity to connect with the researchers whose discoveries help their industry at a mid-July barbeque held at the University of Guelph.
A joint venture of the University of Guelph, Livestock Research Innovation Corporation (LRIC),Poultry Industry Council (PIC), and the Poultry Health Research Network (PHRN), the poultry industry barbeque brought together industry leaders from the poultry commodity groups and industry with University of Guelph leaders, including UofG President Dr. Franco Vaccarino, UofG Vice President of Research Dr. Malcolm Campbell and Ontario Veterinary College Interim Dean Dr. Kerry Lissemore, and researchers from across the campus and beyond. In welcoming the group, Ed Verkley, a director with Chicken Farmers of Ontario and chair of the Poultry Industry Council, noted just how important research is for the industry. The Poultry Industry Council works with the industry to deliver poultry extension services, event coordination, program and project management while supporting research for the poultry sector. The poultry industry is incredibly important to the economy, said UofG president Dr. Franco Vaccarino as he addressed the group. “Knowledge in action is so very important,” he noted, “and this partnership is an example of that.” He added UofG is doing research at all levels from molecular to production and the questions researchers address often come from the industry. “The goal of this event was to create a forum for enhanced interactions and dialogue between researchers, as part of the Poultry Health Research Network, and our industry partners,” said Dr. Shayan Sharif, with the Ontario Veterinary College’s Pathobiology department and leader of the PHRN. “By all accounts, this forum delivered what it was meant to do.” The University of Guelph has had a long-standing commitment to animal health with one of the largest groups of poultry scientists and poultry experts in North America. The Poultry Health Research Network, established in 2012, is a network of poultry researchers and poultry health specialists who address a wide range of issues - from basic biology, to environmental concerns, to poultry disease, production and welfare. The Livestock Research Innovation Corporation works collaboratively on behalf of Ontario livestock and poultry organizations to coordinate research priorities and engage in partnerships to maximize innovation and the return on research.

What do poultry manure and emissions from Alberta’s oil sands have in common? They are both connected to a plant-like organism call micro-algae, which could help the province meet its greenhouse gas emissions reduction targets.
Micro-algae grow by leaps and bounds when fed with poultry manure as an organic fertilizer, which in turn make them more effective for scrubbing greenhouse gases like carbon dioxide from industrial facilities and power plants before they enter the atmosphere.
“Chicken manure is high in nitrogen, phosphorus and potassium. It contains the main nutrients that algae need,” says Bob Mroz, President and Chief Executive Officer of a Maryland-based biotech company called HY-TEK Bio. It is developing and marketing patented technology using micro-algae for mitigation of greenhouse gases.
Alberta likes the potential of HY-TEK Bio’s technology, as the company was recently awarded a $500,000 grant as part of the $35 million international Grand Challenge: Innovative Carbon Uses competition offered by the province’s Climate Change and Emissions Management Corporation (CCEMC). The corporation collects a levy from large greenhouse gas emitters that in turn is used to fund promising technology aimed at reducing greenhouse gases, like the micro-algae technology offered by HY-TEK Bio.
The company has identified a unique strain of micro-algae that is able to absorb 100 per cent of greenhouse gases like carbon dioxide from flue gases produced by industrial manufacturing and power generation.
Micro-algae are photosynthetic, plant-like organisms that need light, water, carbon dioxide and nutrients, mainly nitrogen and phosphorus. They can feed on compounds like carbon dioxide, nitrogen oxide, sulphur dioxide and volatile organic compounds emitted from such facilities as heavy oil production plants and coal-fired power plants, releasing beneficial oxygen in the process and growing into a plant commodity with considerable commercial potential.
The challenge for HY-TEK Bio has been to find an inexpensive source of nutrients to fertilize the micro-algae to accelerate its growth to perform as advertised in a greenhouse gas mitigation application. Addition of nutrients like those in poultry manure make the micro-algae grow faster and increases its production, like fertilizer added to a corn crop.
Mroz says that as the company worked to develop its technology, it encountered organizations like the Chesapeake Bay Foundation, which expressed its concerns about poultry manure seeping into the region’s water drainage system, resulting in considerable algae growth in areas like the Chesapeake Bay. Because of this concern, and the availability of grants, HY-TEK Bio approached researchers at the University of Maryland, which has been working with micro-algae extensively for the past four years, to investigate poultry manure’s potential as a cheap nutrient source. The company already has a working demonstration facility with four bioreactors consuming flue gas emissions from a three megawatt, biogas-fueled power plant attached to a City of Baltimore waste water treatment plant.
University of Maryland scientists are now testing poultry manure as a natural fertilizer to feed micro-algae. The overall plan is to develop a pilot project that demonstrates a process that, in addition to showing how the micro-algae mitigates greenhouse gases, also demonstrates how the poultry manure-derived nutrients can be applied to maintain the growth and health of the micro-algae.
Should the application prove successful and commercially attractive, this could pay a significant environmental and economic dividend to poultry and egg producers, as well as help to solve a growing global problem. Not only would producers of poultry manure have a new and better method for manure disposal, but it could also create a new potential income stream for them.
Dr. Feng Chen, Associate Professor at the University of Maryland Centre for Environmental Science, says there are about 800,000 tons of poultry manure currently being generated annually in the Maryland and Mid-Atlantic area of the United States alone. Most of the manure is land applied as a form of disposal, but the problem is that sometimes the nutrients leach into the water drainage system. An alternative use of this poultry manure as fertilizer for micro-algae would direct that manure into a new, non-polluting direction.
Alberta is one jurisdiction that has shown an interest in what the university and HY-TEK Bio are accomplishing with the use of micro-algae in greenhouse gas mitigation in its massive fossil fuel industry. It has been identified as a notable contributor of carbon dioxide to the atmosphere, especially in its oil sands mining and processing operations.
The University of Maryland research has just started and is being conducted at a basic level, with development of a system to economically extract the nutrients from the raw poultry manure, leading to methods of controlled release of the nutrients to the micro-algae to achieve certain performance targets.
While the research project is still in its early stages, the University of Maryland researchers say that they are “quite encouraged” by the results they have witnessed so far in using poultry manure nutrients to encourage micro-algae growth. The poultry manure they are using was collected from various commercial operations in Maryland. Now, the University is working on such issues as how to develop a consistent liquefied nutrient product from raw poultry manure, given the variability of the raw material from one poultry operation to another.
Mroz says while there is some variability, they all seem to work well as nutrients for micro-algae growth. The main issue is cost of production, taking it from its raw form to a liquid.
“When you are talking about 500 to 1000 of these bioreactor tanks to mitigate a power plant, the nutrient has to be really, really cheap,” says Mroz. About 400 of the company’s micro-algae tanks can fit on one acre, “but we can use multi-storey facilities to increase land usage.”
In addition to establishing an inexpensive process to convert the raw poultry manure to liquid form for use as a micro-algae nutrient, what HY-TEK Bio hopes to achieve through its research project with the University of Maryland is to determine if the brown color of the liquid manure is a deterrent to micro-algae growth because the algae needs as much light as possible to grow.
Should the University successfully develop a method to cost-effectively manufacture a clear, odourless liquid nutrient product from raw poultry manure, Mroz says this also has potential as a marketable, commercial product.
Dr. Russell Hill, Director and Professor at the Institute of Marine and Environmental Technology (IMET) at the University of Maryland Center for Environmental Science, says the University’s research related to using poultry manure as a nutrient source for micro-algae is novel.
“If greenhouse gas mitigation using micro-algae is ever going to really be used on a large scale, the nutrient requirement will be huge,” says Hill. “It could really help to solve the problem of disposal of chicken manure, and potentially it could even put greater value on the chicken manure.”
May 22, 2015 - A national training and certification program for those who handle and transport farm animals will be made available online thanks to $180,000 in government funds. The money comes from Growing Forward 2, a five-year provincial and federal initiative that supports a variety of projects in the agriculture and agri-food industries.
The Canadian Livestock Transport (CLT) Certification program was developed in Alberta in 2007 and has enjoyed national and U.S. participation since the program was moved to the Canadian Animal Health Coalition in 2013. This has included growing international recognition of CLT as an innovative, pioneering program and a leading example of industry-driven leadership in livestock welfare. The overall goal is to help ensure that farm animals in
Canada are transported in a safe and humane manner.
The Canadian Animal Health Coalition is very pleased to receive this funding, said Coalition Chair, Jennifer MacTavish. "It will allow us to advance the highest animal welfare standards in the transport of farm animals," she said. The funding will be used to develop interactive multimedia online materials and delivery of the existing CLT program that is offered to transport drivers and handlers of livestock and poultry.
The program is uniquely Canadian, reflecting Canada's standards and regulations and is available for those who transport or receive cattle, hogs, horses, sheep and poultry. Although voluntary, a growing number of companies that process meat now require drivers and handlers to have this certification, said Mark Beaven, executive director of the non-profit coalition.
It is estimated that 5,000 to 10,000 people are involved in the transportation of animals in Canada. Currently, about 1,500 transport drivers and handlers who load and unload livestock and poultry are certified. Re-training is required every three years to maintain certification and the online program will not only make the recertification process more efficient and consistent but will allow more people across the country to participate, said Beavan.
The training involves everything from knowing the regulations and proper techniques for the safe handling of animals, to loading capacities and avoiding overcrowding as well as biosecurity and other protocols that are necessary to protect agricultural industries. Program details can be found at www.livestocktransport.ca.
"This funding allows us to take the program into the 21st century," he said. "It will be very interactive and intense, but it allows the current participants to be recertified and new ones to come on board and do it at their own pace."
It will build Canada's reputation as "a world leader" in the safe and humane handling of farm animals, he added.
May 7, 2015, Calgary - A breakthrough innovation in enzyme technology is breathing new life into the ability of swine and poultry operations to get the most “bang for bite” possible from feed rations.
Multi-carbohydrase technology – now widely available in the latest Superzyme feed enzyme series from Canadian Bio-Systems Inc. (CBS Inc.) – is designed to deliver higher nutritional extraction from a wide range of animal feeds including corn, soybean meal, wheat, barley, oats, canola meal, flax, peas and distiller’s dried grains with solubles (DDGS).
Particularly effective with young animals, swine trial data results show 11 percent improvement in average daily gain and 15 percent improvement in feed conversion ratio for newly weaned pigs (multi-carbohydrase vs. untreated control). Poultry trial data results show 2.7 percent improvement in body weight gain and 3.2 percent improvement in feed conversion ratio (multi-carbohydrase vs. untreated control, using corn-soy diets).
This adds value to feed, reduces potential waste and presents a new way to gain a competitive advantage and enhanced profitability, says Dr. Bodgan Slominski, head of a long-standing research program in Western Canada that investigates the potential of novel feed ingredients.
“Multi-carbohydrase technology represents the leading-edge of our science-based knowledge on the most effective use of feed enzymes,” says Slominski. “It leverages what we have learned from many years of research to offer a much more comprehensive and sophisticated option than traditional approaches.”
CBS Inc. has funded and partnered in pioneering research on multi-carbohydrase technology to drive this concept forward. This has included numerous key studies directed by Slominski as part of his program at the University of Manitoba, recognized as one of the leading programs of its kind in the world. This research received the Synergy Award for Innovation from the Natural Sciences and Engineering Research Council of Canada as well as the National Research Council Award for Innovation in Industrial Research.
This base of science is providing the foundation for a new wave of multi-carbohydrase technology products, led by Superzyme – “the original multi-carbohydrase.” A flexible platform for use with a variety of swine and poultry diet formulations, Superzyme is becoming widely available for 2015 through expanded distribution in the U.S., Canada and more broadly internationally, say Rob Patterson, Director of Technical Services with CBS Inc.
“The multi-carbohydrase technology embedded in Superzyme is different from other ‘NSP’ enzymes and ‘enzyme cocktails," says Patterson. “This technology utilizes multiple unique enzyme strains that express multiple activities, as opposed to blending single-source enzymes together. Theses enzyme activities are painstakingly identified, researched and developed to ensure they complement one another seamlessly and deliver a high level of both individual and synergistic benefits.”
A new website, www.superzyme.info, offers a valuable resource for industry to learn about the multi-carbohydrase approach. It includes an overview of the Superzyme product, where it fits in the history and evolution of enzyme technology, step-by-step details on the fermentation process, information on competitive advantage benefits, and contact information for sales and support. An extensive technical summary is also available.
"The fact is that if we don’t learn how to recycle nutrients and water, we are doomed. We will start dying off from hunger. This is just one approach to prolong our existence on this planet.”
That ominous warning comes from Nick Savidov, senior research scientist at the Bio-Industrial Opportunities Branch of Alberta Agriculture and Rural Development (AARD).
By recycling nutrients and water, he means extracting the valuable nutrients from waste streams like poultry manure by using microorganisms in an oxygen-rich environment within a device called a bioreactor to mineralize and dissolve the nutrients in a liquid solution. The nutrients can then be re-used as plant food. Savidov describes this as a sustainable approach to agriculture that could help save humanity from starvation down the road.
Tapping into this source of organic fertilizer from aerobic bioreaction is critical to continued human life on Earth, says Savidov, because current synthetic fertilizer sources are non-renewable. For example, he says that according to the most recent survey by the International Fertilizer Development Centre (IFDC), 85 per cent of all phosphorus rock reserves on the planet, which are used to produce phosphorus fertilizers are located in just one area - in Morocco and the Western Sahara. Also, current nitrogen synthetic fertilizers can only be produced using non-renewable fossil fuels. Sources of synthetic fertilizers now in widespread use are a finite resource that will eventually run out. Nutrient and water recycling to capture these same nutrients from animal waste streams offers hope to feeding humanity in future.
He is working with an AARD research team, which includes engineer and system designer, Marc Legault, to demonstrate the use of an aerobic bioreactor to mineralize nutrients from raw poultry manure. They used the dissolved organic fertilizer, called “digestate” to grow market garden vegetables and tree seedlings in a soil-less growing environment. So far, the results have been highly successful.
For example, seedlings of lodgepole pine and white spruce fed with this mineralized organic nutrient stream, “doubled in height after two months. The results exceeded all our expectations,” says Savidov.
The organic fertilizer was also used to grow greenhouse tomatoes, and a 15 per cent higher yield was achieved versus use of synthetic fertilizer because of enhanced nutrient uptake by the plants.
“We demonstrated that we can produce vigorous growth of major nursery crops grown in Alberta and B.C., using poultry manure digestate,” says Savidov.
It is common practice right now to grow market garden vegetables and tree seedlings in greenhouses that use no soil, where the plant roots are immersed in liquid environments and fed computer-controlled, metered amounts of synthetic fertilizers to promote growth. But these Alberta researchers want growers to consider using mineralized organic fertilizers extracted from animal waste instead of synthetic fertilizers because it is a more sustainable form
What’s different and proving more beneficial by using recycled organic fertilizers instead of synthetics is that they are biologically active with beneficial microorganisms. In addition to exceptional growth over a short period of time, the tree seedlings also experienced enhanced root biomass development, robust health such as better resistance to root pathogens, and improved nutrient uptake, meaning that they experienced exceptional growth in low nutrient solutions. In other words, growers can use small amounts to achieve big results, which could be a huge economic benefit. Furthermore, the water used in these soil-less growing systems is recycled so that there is less pollution released to the environment, and the grower achieves greater water use and nutrient uptake efficiencies.
Researchers chose to work with poultry manure as their raw material because it was readily available, rich in nitrogen, and less fibrous than cattle manure, which because of its fibre content, takes longer to ferment. The processed poultry manure resulted in organic fertilizer with low sodium content, which can be toxic to plants in higher concentrations, and pH within the tolerable range for plants.
Savidov emphasizes that whether it is synthetic fertilizers or this type of organic fertilizer, the nutrients have to be mineralized so they can be used as plant food. He adds that what’s new about this process versus the common practice of creating organic fertilizer by composting manure is that this aerobic bioreaction conversion process is much faster -- taking two to three weeks versus three months to a year with composting. Also, this method results in 100 per cent conversion of the raw manure to valuable, liquid plant food versus composting or the other commonly known method of converting animal manure to organic fertilizer — anaerobic digestion. This is the process of converting manure to organic fertilizer and biogas in an oxygen-free environment.
The researchers’ goals were to prove that it is possible to create a liquid, biologically-active, organic fertilizer from raw animal manure using their aerobic fermentation method and that plant response from this organic fertilizer in a soil-less growing environment is as good as or better than the use of synthetic fertilizers.
Savidov says it is possible to extract valuable nutrients using their bioreactor system from all forms of animal manure or other food and agriculture by-products but they started with poultry manure. Ultimately, converting manure to a liquid nutrient stream using their bioreactor technology could represent a new income stream for farmers like poultry producers, as well as a non-synthetic, biologically active, fertilizer source for growers. The conversion process also produces heat, which can be used to heat poultry barns.
An aerobic bioreactor is not expensive, space-age technology. It is easily achievable, relatively inexpensive technology. The bioreactor is simply a septic tank with a built-in agitator. Oxygen and water is added to the tank along with the manure to create a slurry. Intense mixing within the tank is critical to maintain consistent fermentation. Savidov says there is no odor during the reaction process, except when the raw manure is added because oxygen reacts with common odor-causing compounds like hydrogen sulfide. Because all components within the raw manure will completely mineralize over different time intervals, there will be some solid material left in the liquid outfeed stream after three weeks. After about three weeks, the bioreactor is stopped and the processed liquid is removed to a filtration tank. The solids are separated from the liquid and returned to the bioreactor for further fermentation, while the liquid stream is ready for use as organic fertilizer.
“To be honest, it’s not really an absolutely new system,” says Savidov. “It’s using bits and pieces of what is already used in the agriculture industry for manure treatment.” He adds that greenhouses and nurseries would have to change very little to convert from synthetic fertilizer use to this type of organic fertilizer.
The researchers hope that aerobic fermentation of animal manure into organic fertilizer will become a common practice, either on farms, by commercial organic fertilizer producers, or directly at greenhouses or tree nurseries. It is currently used in some parts of Europe to treat cattle manure.
April 13, 2015 - A simple and effective portable tool to predict avian flu outbreaks on farms
has been created by University of Guelph researchers.
U of G researchers devised a real-time way to analyze chickens and other farm birds for avian flu. The tool uses a small blood sample and relies on a simple chemical colour change to see not only whether a chicken has avian flu but also what viral strain is involved.
Current tests require samples to be sent to a lab, where it can take eight hours to a couple of days to yield results. That's too long, said Prof. Suresh Neethirajan, School of Engineering.
"Treatment, especially when dealing with humans who have been infected,needs to start as soon as possible," he said. "This test only needs two to three minutes to incubate, and then you get the
results immediately. Not only that, but it is more cost-effective. Conventional techniques are time-consuming and labour-intensive, and requirespecial facilities and expensive laboratory instruments."
A study about the device will appear in an upcoming issue of the scientific journal Sensors, published by Molecular Diversity Preservation International (MDPI).
Last week, Canadian officials placed eight farms in southern Ontario under quarantine after an avian influenza outbreak caused the sudden deaths of thousands of birds over several days.
Preliminary testing on the strain was conducted at U of G's Animal Health Lab.
An outbreak of avian flu also took place in Canada in January and December of 2014.
Neethirajan and post-doctoral researcher Longyan Chen wanted to create a test that could be used by anyone, even a non-scientist.
"That is why we designed it so that the final colour changes based on what type of influenza it is, and it can differentiate between a human strain and a bird strain," said Neethirajan.
"It's critical to get out front of any outbreaks. There are many strains, and we need to know the source of the flu. The identification of the strain determines what treatment options we should use."
The device uses gold nanoparticles (microscopic particles) and glowing quantum dots. The researchers developed a novel approach for rapid and sensitive detection of surface proteins of viruses from blood samples of turkeys.
The new nanobiosensor can detect the strains of H5N1 and H1N1. The most recent outbreak was from H5N2, which is similar to H5N1, Neethirajan said. With some architecture modifications, the developed biosensing technique has the potential to detect the H5N2 strain as well, he said.
The subtype H1N1 is human adapted while most H5 are avian oriented, Neethirajan added.
"We're creating a rapid animal health diagnostic tool that needs less volume of blood, less chemicals and less time. We will be able to determine, almost immediately, the difference between virus sub-strains from human and avian influenza."
As consumers, retailers and the broader community continue to demand movement towards housing systems that place high value on offering improved behavioural opportunities for hens, it’s important to track measures related to their physical condition. Do the proposed solutions carry unintended consequences? What are the physiological and physical effects of more open housing systems?
As a benchmarking tool, researchers Mike Petrik, Michele Guerin and Tina Widowski have just published a study that gives a snapshot of commercial Ontario brown laying hens in cage and non-cage systems using three welfare indicators: keel bone fracture prevalence, feather scores and cumulative mortality. These three parameters are typically used to reflect some of the physical aspects of the welfare status of the hens.
Benchmarking welfare indicators from alternative housing systems is important to ensure that progress is made in improving their well-being. This is the first study in North America to compare housing systems on multiple farms as well as providing a more detailed assessment of keel fractures during the life of a flock.
There are 64 farms in Ontario housing brown hens in cages with an average flock size of 9,965, while 27 farms average 9,410 hens per flock in floor-housed systems. For their study, Petrik et al. recruited nine commercial farms that housed brown hens in cages and eight farms using floor systems. Only brown hens were included because there are no white hen flocks housed using floor systems in Ontario at present.
All hens were beak trimmed; caged pullets were grown in caged housing and floor flocks were grown in single-tier floor pullet houses. All birds were fed a commercial diet that was adjusted to individual flock requirements.
Hens were sampled four times over the course of lay, at 20, 35, 50 and 65 weeks of age. At each visit, 50 hens were weighed and palpated for evidence of healed keel bone fractures. Feather scores were assigned based on evaluation of the neck, back, breast and vent. The daily records maintained by the farmer provided mortality data.
Keel fracture prevalence was significantly higher for the floor housing compared to conventional housing. As birds neared the end of lay at 65 weeks, the fracture rate was 54.7% compared to 40% for caged flocks. These floor-flock figures were comparable to those for floor birds in Europe (45 to 86%) but the conventional numbers were greater than those reported in conventional cages in the UK (26 to 30%). This might be due to the difference in cage size (483 cm2 in North America vs. 550 cm2 in Europe) that may result in more piling behaviour, or possibly cage design or nutritional factors.
Keel fractures are often attributed to traumatic injury. Five of the eight floor barns in this study had no perches; the researchers suggested that fixed perches were not a contributing factor to the incidence of keel bone fractures in these flocks.
While most studies evaluate keel fractures at the end of lay, this study points to fractures occurring much earlier in production. In this study, the fracture prevalence increased substantially from 20 to 50 weeks in both floor and cage systems, after which the incidence stabilized. This is a serious concern because fractures occuring early in lay results in a higher potential for chronic pain over the course of production.
Flock-level mean feather score was not significantly affected by the housing system, possibly due to the hens having been beak trimmed. Cumulative mortality tended to be lower (1.29%) for cage housing than floor housing (2.13%), but the figure for floor housing was much lower than in other studies, which have indicated that non-cage systems put hens at a much higher risk for feather pecking, cannibalism and mortality for various reasons. These feather condition and mortality results showed that these Ontario flocks performed really well.
Mean body weight was lower but more uniform in floor housed flocks compared to cage housed flocks, possibly due to a higher activity level and the need to search for feed. Heavier birds had more fractures, so in a chicken or egg type of question, did heavier birds have more keel fractures because of their weight, or were they heavier because of less activity due to the fracture? Production parameters and behaviour were not evaluated in this study.
More work is indicated to identify specific risk factors and etiology of keel fractures, especially if non-cage housing becomes more common in North America. These findings indicate that younger hens, between 20 and 35 weeks of age, showed the highest incidence of keel bone fractures and should be the focus of future studies.
As the layer industry continues to evolve, the benchmarking of welfare indicators from alternative housing systems from this study will help to ensure that progress is being made to improve the well-being of the hens.
This research was funded by Egg Farmers of Canada and the Ontario Ministry of Agriculture and Food. The researchers would like to thank participating egg farmers in Ontario for allowing access to their flocks and records.
Vaccination is one method used to help prevent the spread of infectious poultry diseases, but current vaccines could be safer and more effective.
At the Agricultural Research Service’s Southeast Poultry Research Laboratory (SEPRL) in Athens, Georgia, scientists are developing vaccines to help reduce virulent virus shedding—excretion of virus by a host—and disease transmission from infected birds to healthy ones.
Microbiologist Qingzhong Yu and his colleagues have created a novel vaccine that protects chickens against infectious laryngotracheitis virus (ILTV) and Newcastle disease virus (NDV), two of the most economically important infectious diseases of poultry. Both viruses cause sickness and death in domestic and commercial poultry as well as in some wild birds throughout the world.
“While current ILTV live-attenuated vaccines are effective, some of the viruses used to make them can regain virulence—causing chickens to become chronically ill,” says Yu. “Other types of vaccines can protect birds from the disease’s clinical signs, but barely reduce the virus shedding in their respiratory secretions after infection. Those vaccines are not that effective, because they do not reduce the risk of virulent ILTV transmission to uninfected birds.”
Most vaccines used in the United States are formulated with NDV isolated in the 1940s. However, since then new NDV strains have emerged that are genetically different, according to Yu.
Worldwide, the NDV LaSota strain has been used as an NDV vaccine. “It is very stable and very effective, and there have been no reports of virulence increase,” Yu says.
In previous research, SEPRL scientists successfully used LaSota strain-based viruses to develop vaccines that protect birds against two other poultry viruses—metapneumovirus and infectious bronchitis virus. Now, in a recent study, Yu used reverse genetics technology, which allowed him to generate new vaccines by inserting a gene from the ILTV virus into the NDV LaSota strain.
The new vaccines were stable and safe when tested in chickens of all ages. Experiments involved more than 100 1-day-old Leghorn chickens and 120 3-day-old commercial broilers. All vaccinated birds were protected against both ILTV and NDV, showing few or no clinical signs and no decrease in body-weight gain.
These vaccines worked as well as current live-attenuated vaccines, Yu says. They can be safely and effectively administered by aerosol or drinking water to large chicken populations at a low cost.
“There is a huge market for these types of vaccines because they can protect poultry from ILTV as well as NDV,” Yu says. “Developing a commercial vaccine that provides better protection against disease would have a positive economic impact on the U.S. poultry industry and also make its products—meat and eggs—less expensive for consumers.”
NDV causes disease in more than 250 species of birds and typically causes respiratory, gastrointestinal, and/or nervous system symptoms. The most severe form of Newcastle Disease can result in disease and mortality rates exceeding 90 per cent in susceptible chickens.
The most recent U.S. outbreak, which occurred in 2002-2003 in California, Nevada and Texas, illustrates the devastation and financial cost that can result: more than 3.4 million birds were destroyed, and the cost of controlling the outbreak in California alone was more than $160 million.
ARS has filed for a patent on the vaccine invention, which has generated interest from private companies that are considering using this research to develop commercial vaccines.
This research is part of ARS National Program #103, Animal Health.

April 6, 2015 - Two senior appointments have been made by Cobb-Vantress to strengthen its research and development team.
Dr. Anu Frank-Lawale, who has wide experience across a range of species, joins the team as pedigree geneticist, while Dr. Frank Siewerdt moves from this role to become director of genetics responsible for the Cobb genetic program.
Dr. Anu Frank-Lawale is based at the Three Springs pedigree farm in Oklahoma, where he will be responsible for the selection program in several commercial and experimental lines. He studied animal breeding at the universities of Nottingham and Edinburgh in the UK, and went on to gain a PhD for work on aquaculture genetics at Stirling University.
He worked as a biometrician at the Roslin Institute, Edinburgh, and then in 2007 moved to the United States as breeding research manager for the Aquaculture Genetics and Breeding Technology Center at Virginia Institute of Marine Science.
Dr. Frank Siewerdt now has a team of seven PhD geneticists and a business engineer working with other areas of R&D and the business units to continue genetic progress on existing Cobb products and developing new ones to meet market needs.
He joined Cobb three years ago as the inaugural geneticist at the new Dry Creek complex in Deer Lodge, Tennessee, and became responsible for the genetic program in two of the pedigree farms. Originally qualifying from the Federal University of Pelotas in Brazil, Dr Siewerdt obtained his PhD from North Carolina State University in the USA and has worked for more than 20 years in academic and industry positions including four years with Heritage Breeders / Perdue Farms.
Birds with certain characteristics are of absolute importance to poultry breeders. In terms of both broiler and layer flocks, bone development resulting in strong and healthy skeletal structure is of particular interest. Weak bone formation as a consequence of a developmental imbalance results in significant financial loss to the poultry industry. Dr. Andrew J. Bendall, a developmental biologist from the University of Guelph has embarked upon a project that aimed to design a new class of research tool to manipulate gene expression in developing embryos, which would allow researchers to decipher how these genes function in early skeletal development. Dr. Bendall described the long-term benefit to poultry producers of his research as “identifying genes that could be targeted for selective breeding for improved skeletal development and health”. This research commenced in 2011, with the identification of key regulatory genes that affect skeletal development in the chicken embryo, and subsequently have consequences for adult skeletal function and integrity. Once this was completed, the researchers were able to develop novel molecular tools that allow disruption or silencing of these gene functions. These tools were designed to not only silence one gene, and have the potential to silence multiple genes within the embryo. “Development of such tools will be of great benefit to other researchers for further studies in the chicken embryo” says Dr. Bendall. With respect to current status of their findings, Dr. Bendall explains “We identified multiple sequences that silence genes of interest and are continuing to test their effects in the embryo.” Once this is completed, they plan to further enhance the molecular tools to allow the silencing of the genes to be performed in a targeted cell type. Such tools will greatly advance poultry research, as cell type specific manipulation of gene activity has not been achieved in the chicken to date. “This project represents proof of principle for longer-term functional studies where we investigate embryonic development of the skeleton.” This project was funded equally by the Poultry Industry Council (PIC) and Natural Science and Engineering Research Council of Canada (NSERC) through the NSERC Collaborative and Research and Development (CRD) grants program.
Incubation temperatures for egg embryos may need to be adjusted depending on the age of the broiler breeder flock and the strain of bird. A study completed by Prof. Doug Korver at the University of Alberta shows that embryos from older flocks produce more of their own heat and if they overheat, embryonic metabolism actually slows down, which can affect early chick quality.
“The metabolism of broiler chickens has changed substantially as they’ve been selected for growth rate and breast meat yield, but incubation time has not,” explains Korver. “Modern embryos tend to produce more heat, and as breeder birds get older, they lay bigger eggs with the potential to produce more heat.”
Korver’s small but intensive study involved two modern commercial strains of broilers, Ross 308 and Ross 708.
Embryos from young breeder birds (26-34 weeks old), mid-production breeders (35-45 weeks old), and older breeder flocks (age 46-55 weeks) were incubated at four different temperature settings: 36C, 36.5C, 37C and 37.5C.
“Because the smaller embryos from younger breeder flocks produce less heat, they may need additional warmth in the incubator, whereas embryos from older flocks may need to be pulled from the hatcher sooner,” explains Korver.
The optimum incubator temperature was found to be 37C; at higher temperatures, the Ross 708 embryos reduced their metabolism to try to avoid overheating, although this wasn’t the case with the Ross 308 strain.
“Chick quality measures like weight and residual yolk sack weight were optimized at 37C,” he says. “In general, we tend to see lower growth rates and poorer performance with higher residual yolk sack weights.”
The study results show that as genetic selection continues, it may become more necessary to target hatcher management based on the age of the breeder birds.
Currently, however, most of the industry uses multi-stage hatchers with embryos from different ages of breeder birds and from different bird strains all going through together, which can make it challenging to tailor incubation conditions for a specific group of eggs.
“As the industry moves to single stage hatchers, it will become more feasible to target incubation to different batches of eggs,” says Korver.
The CPRC completed its 2014 funding process at the Board of Directors November meeting by providing approval for eight projects that address several poultry industry priorities. Final approval for some projects is based on the researchers securing full funding for their proposed research projects, while other projects are fully funded and ready to begin. The board also awarded the 2014 Postgraduate Scholarship, a difficult task because of the very strong group of applicants.
Carl Lessard, an Agriculture and Agri-Food Canada researcher located at the University of Saskatchewan (U of S) and curator of the Canadian Animal Genetic Resources program, will conduct research on conservation and regeneration of chicken and turkey breeds using adult gonadal tissue. The CPRC has funded a series of projects to examine the potential for cryopreservation of poultry genetic material and this project carries that research program forward.
Poultry Welfare and Behaviour
Three projects address welfare and behaviour issues. Tina Widowski from the Poultry Welfare Research Centre at the University of Guelph (U of G) will evaluate existing and new euthanasia technologies for chickens and turkeys. Karen Schwean-Lardner plans to conduct tests of the impacts of infrared beak trimming on young pullets’ behaviour, water consumption and ability to peck. Martin Zuidhof from the University of Alberta and Gregoy Bedecarrats from the U of G, will cooperate on research to optimize lighting for precision broiler breeder feeding. Zuidhof developed a computerized precision feeder in prior research to ensure optimum broiler breeder weight is maintained to help maximize production.
Immune System Enhancement
Improving the innate immunity of poultry is a major industry priority with the increasing discussion of the use of antimicrobials and potential for increased antimicrobial resistance in animals and humans. Three projects look at methods to improve the poultry immune system. Shayan Sharif from the Ontario Veterinary College at the U of G, will investigate the effect of in ovo delivery of nutrients and feed additives on the development of the chicken immune system. Susantha Gomis, from the U of S, will continue research previously funded by the CPRC that looks at the use of CpG-ODN to stimulate the innate immunity in poultry. Mohamed Faizal Careem, from the University of Calgary, will test the use of in ovo delivered innate immune-system stimulants to increase resistance to respiratory viruses. This research is also a follow-up to work that the CPRC previously co-funded.
Screening of birds for disease is used to identify potential outbreaks that could damage a flock or increase risks to poultry production in a region or the country as a whole. Present approaches to testing for exposure to avian influenza for the national surveillance program are based on taking blood samples from birds and sending them to a laboratory for analysis. Kathleen Hooper-McGrevy of the Canadian Food Inspection Agency’s National Centre for Foreign Animal Diseases will evaluate a standardized test to use egg-derived immunoglobin for screening of antibodies to avian influenza to avoid the stress and cost associated with handling layers and taking blood samples.
CPRC Scholarship Award
The CPRC awarded its 2014 Postgraduate Scholarship to Alexander Bekele Yitbarek, a Ph.D. student under the supervision of Professor Shayan Sharif at the U of G. Yitbarek completed his M.Sc. at the University of Manitoba in 2009 and then worked with Juan Carlos Rodriguez-Lecompte as a research technician until 2013. He followed that as a research associate with Nutreco Canada until commencing his studies with Sharif.
Yitbarek’s research will look at poultry immunology and developing a better understanding of the role of different toll-like receptors and cytokines in modulation of the immune system in chickens. His research focus will be mainly in understanding the role of TLR receptor ligands in controlling avian influenza virus. He will also conduct research on the effect of probiotics as nutritional modulators in the search for the replacement of antibiotic growth promoters in poultry diets.
The membership of the CPRC consists of Chicken Farmers of Canada, Canadian Hatching Egg Producers, Turkey Farmers of Canada, Egg Farmers of Canada and the Canadian Poultry and Egg Processors’ Council. CPRC’s mission is to address its members’ needs through dynamic leadership in the creation and implementation of programs for poultry research in Canada, which may also include societal concerns.
Finding a way of turning poultry bedding into a valuable resource in a cost-effective way is difficult. But it didn’t stop B.C. Agriculture Research and Development Corporation (ARDCorp), B.C. Sustainable Poultry Farming Group (SPFG), Ritchie-Smith Feeds and Diacarbon Energy, from trying. The groups optimistically embarked on a trial to turn this material back into fodder.
Anyone who works in B.C.’s poultry industry is aware that a creative, cost-effective disposal solution is required for the excess volumes of used poultry bedding accumulating from the over 100 million chickens and turkeys produced annually. Finding a way of turning this abundance of bedding into a valuable resource is even harder. But that was the goal of the B.C. Agriculture Research and Development Corporation (ARDCorp), B.C. Sustainable Poultry Farming Group (SPFG), Ritchie-Smith Feeds and Diacarbon Energy, who optimistically embarked on a trial to turn this material back into fodder.
Used poultry bedding has been used for centuries as a soil fertilizer. But only so much of the bedding can be used on the land before the nutrients start leaching into the environment, becoming a risk rather than an asset.
With a relatively low moisture content of 30 to 40 per cent, it is possible to transport broiler litter to nutrient deficient areas for land application. However, on average, a tonne of broiler litter contains less than 200 lbs of nitrogen, phosphate and potash, while a tonne of commercial fertilizer contains over 700 lbs. Due to its low nutrient content to weight ratio (when compared to commercial fertilizer), it is often uneconomical to transportation broiler litter over long distances. While this distance depends heavily upon transportation costs and the cost of commercial fertilizer, a good rule of thumb is that broiler litter should be used within 50 to 100 kilometres of the source. For the Lower Mainland, which raises close to ninety per cent of B.C.’s poultry, the current nutrient surplus is a concern. The poultry sector’s quest for a viable alternative to the land application of bedding was the reason for this recent feed study.
In other parts of the world, some success has been achieved with turning used broiler bedding into biochar and adding it to broiler feed, thereby improving the broiler’s feed conversion and increasing final weight. Fueled by the success of others, ARDCorp, the SPFG and the Ministry of Agriculture hoped that through conducting their own experiment, they could create demand for roughly ten per cent of the used broiler bedding in the Lower Mainland; and, at the same time, improve production.
Biochar is made by burning biomass material at extreme temperatures of over 500C in an oxygen-free environment. This process, called pyrolysis (thermochemical decomposition), is a very effective disinfection technique, ensuring that the biochar is free of any possible pathogens.
When applied to soils, the high surface area and porosity of biochar act as a catalyst for plant growth by helping to retain water and by providing a habitat for beneficial microorganisms to flourish.
More recently, there has been interest in how biochar aids in the grinding process and provides a habitat for beneficial microoganisms in the digestive system. It has been claimed that the consumption of biochar by broilers can increase update of foodstuffs and the energy contained within them. Increased uptake can thus result in increased weight gain and/or improved feed conversion.
Although the idea of supplementing broiler feed with biochar made from broiler litter may seem strange, it should be noted that processed poultry litter has been used as a feed ingredient for almost 40 years in the U.S.
For this study, used broiler bedding was taken from a commercial broiler barn in the Fraser Valley and dried before being delivered to Diacarbon’s pyrolysis unit in Agassiz. Once processed, the resulting biochar was transported to Ritchie-Smith Feeds in Abbotsford where it was incorporated into commercial starter, grower and finisher broiler feed. The feed was delivered to S.J. Ritchie Research Farms Ltd in Abbotsford for a floor pen study.
The study involved 288 broiler chicks arbitrarily placed into twenty-four specially constructed pens. The chicks in each pen were given feed supplemented with biochar or feed without biochar for 35 days. The broilers were weighed individually once weekly and the weights recorded. All feed was also weighed weekly and any feed remaining in the feeders was weighed back and replaced.
Unfortunately, the hoped-for outcomes of the study did not come to pass. From the results of this study it can be concluded that supplementing broiler feed with broiler litter biochar had no statistically significant impact on broiler weight gain and/or feed conversion (Table 1). While unknown as to why, it could be because of the nutrients in broiler litter; a result of the droppings and spilled feed that gets mixed in with the bedding material. It is therefore possible that the supplementation of broiler litter biochar resulted in the broilers being feed too high levels of certain nutrients. This assumption would go some way to explain the high levels of Sodium (Na) and Chlorine (Cl) found in the litter from T2 and T3 pens (Table 2).
In other studies that have found significant benefits from supplementing broiler feed with biochar, other feedstocks were used to make the biochar; including oak, pine, coconut shells, corn cobs and peanut hulls. It is therefore possible that had an alternative feedstock be used (such as pine instead of broiler litter), supplementing broiler feed with biochar may have been a statistically significant impact on broiler weight gain and/or feed conversion.
While the biochar feed study might have ruled out one opportunity, it has opened doors for others. The main objective, after all, is to find sustainable ways of managing used broiler bedding. And if supplementing broiler feed with broiler bedding biochar did not work as expected, then the question should be: where can the industry look next?
Allen James, Chair of ARDCorp, and a member of the SPFG hopes researchers can find a positive way to convert the poultry bedding into energy. “As long as there’s an excess of bedding, we’ll be looking for a solution.” He is hopeful we will find a local solution to our local situation.
Other applications of biochar have proved successful, but perhaps not economically feasible for the Lower Mainland. Biochar has been used as a soil conditioner to improve water retention and nutrient density to aid in the growth of plants and increase yield. Biochar is also considered a superior growing medium in hydroponics, which is a rapidly growing technology. All of these areas could be expanded upon, creating financial opportunities for the poultry industry.
“Many studies have been done in the U.S,” explains James, “but none of them relate to B.C. and our particular situation. We’ll keep pressing on as long as the industry has this situation to deal with.”
For B.C., a new study is planned for 2015 to convert poultry litter into heat and electricity. This project could potentially have positive impacts on both the environment and animal waste management, and be one solution to how we can turn trash into treasure. We will have to wait for the results to come in, and look forward to future projects, which will help answer the burning question.
Any inquiries about this study and requests for details should be directed ARDCorp’s Senior Program Manager Jaclyn Laic (604) 854-4483.
Funding for this project has been provided by Agriculture and Agri-Food Canada and the B.C. Ministry of Agriculture through the Canada-B.C. Agri-Innovation Program under Growing Forward 2, a federal-provincial-territorial initiative. The program is delivered by the Investment Agriculture Foundation of B.C.
