The level of early chick mortality (ECM) is one of the crucial factors that determines the quality of chicken production and, hence, the economic return from a poultry production unit. Yolk sac infection (YSI) has been reported as the most frequent cause of ECM, and in recent years significant increase in ECM due to YSI has emerged as a threat to broiler operations in parts of Canada.

Sector - Broilers
Feeding young broiler breeders around the world generally involves restriction starting when the chicks are one week or a few weeks of age. This is done so that they grow at a rate that supports their health and welfare – one that prevents obesity, lameness and reproductive problems.
Last year, Canadian Poultry outlined how some North American retailers were starting to source slow-growth broiler meat due to pressure over welfare concerns with conventionally grown chickens. Now, we look at economic, environmental and animal welfare factors attached to slow-growth broilers and also at Europe’s experience.
Research shows that under natural conditions, domestic fowl spend 70 per cent of their active time foraging by walking on the ground because their flight abilities are limited. When threatened or roosting, domestic hens seek elevated refuges. For roosting, birds fly up to the lowest branch of a tree and seek higher elevation by flying branch-to-branch, whereas they descend by flying directly to the ground. Hens use their wings only for brief escape flights.
There’s a new poultry ration ingredient available on the Canadian market. Insect meal from defatted black soldier fly larvae is high in protein and low in fat, making it a potentially attractive alternative to soy in poultry diets.
The study, headed by animal welfare expert and U of G professor Tina Widowski, is expected to provide key information for ensuring that broiler chickens – the world’s most popular meat – are raised not just quickly and efficiently but ethically as well.
“Animal welfare has become a big part of the notion of sustainability – how to improve welfare and create a healthy environment, and how to make it economically feasible,” Widowski says.
About 23 billion broiler chickens are produced worldwide; Canada produced more than 700 million of the birds in 2017.
Most North American broiler chickens are conventional, fast-growing birds that reach a market weight of 2.1 kilograms in about 35 days.
Developed over the past half-century through a combination of selective breeding and genetics, better nutrition and improved husbandry practices, those growth speedsters also pack on proportionately more breast meat and less bone.
But fast-growing modern broilers are susceptible to immune system and musculoskeletal problems, said Widowski, an animal biosciences professor and holder of the Egg Farmers of Canada Chair in Poultry Welfare and the Col. K.L. Campbell University Chair in Animal Welfare.
Often, their legs are not strong enough to support their meaty bodies, making it difficult for the birds to walk. These sedentary chickens spend much of their time sitting and lying on litter in their free-run houses, which can lead to foot and skin problems, she said.
“Animal welfare concerns for these fast-growing chickens have led to the development of new, slower-growing genotypes,” Widowski says.
Slow-growing chickens take at least a week longer to reach market weight than conventional birds and are reported to have improved welfare and better meat, she added.
Broiler chicken health and welfare is a focus of the Global Animal Partnership (GAP), an organization based in Austin, Texas. Over the past year, dozens of multinational restaurants, grocers and food service companies have pledged to source only broilers raised under GAP standards.
However, conventional chicken producers argue that raising birds more slowly will add expense, particularly in extra feed, which accounts for about 70 per cent of producer costs. “It’s a very contentious issue,” Widowski says.
What’s missing in the debate, she said, is research to back up those welfare standards and to determine optimum breeds and management methods. Looking for that information, GAP came to U of G for help.
“There’s been no comprehensive look at health, welfare, nutrition, environment and meat characteristics,” Widowski says.
Referring to the University’s strengths in poultry science and welfare, she adds, “Here at Guelph, we have the capacity to do that.”
U of G researchers are now assessing 20 strains of conventional and slow-growing breeds. They’re tending about 1,000 birds at a time, hatched from eggs supplied by the world’s largest breeding companies.
Three grad students and a post-doc researcher are tracking the birds with various instruments, including the “chicken fitbits.”
By monitoring behaviour, physiology, health, production and meat quality, the team hopes to nail down welfare indicators for all strains.
“This study will provide information people can use to make decisions,” says Stephanie Torrey, a senior research associate in the Department of Animal Biosciences.
U of G received a total of about $1 million for the study from GAP, U of G’s Food from Thought project and the Ontario Ministry of Agriculture, Food and Rural Affairs.
An important online survey component of the project launched over the summer is already seeing strong participation across the industry.
Those who haven’t yet participated in the survey are encouraged to do so as soon as possible, ahead of the Oct. 31 deadline. (Click here to complete the survey).
“Broad industry feedback is critical to accurately represent the extensive work being done related to livestock care in Alberta today, and to help shape future priorities and direction around this increasingly high-profile component of livestock production,” says Annemarie Pedersen, executive director, AFAC.
“We have been very encouraged by the strong initial participation in the survey, which is open to anyone involved in animal agriculture in Alberta,” says Dr. Melissa Moggy, Livestock Welfare Engagement Project Lead.
With the initial consultation completed and the survey underway, planning for the focus groups is in full swing. “Our first of five focus groups will be at Grande Prairie Regional College, Fairview Campus, on Sept 20th and we hope anyone involved in the industry will join us for an in-depth discussion of livestock welfare in Alberta,” says Moggy. The results will be a critical part of the final report to be shared with government in early 2019.
Locations and details for these additional focus groups can be found below. Focus groups will be arranged by invitation, based on survey responses. However, those who are interested in participating in their area can register.
Grande Prairie Regional College – Fairview, Alta. - Sept. 20
Lethbridge College – Lethbridge, Alta. - Sept. 25
Olds College – Olds, Alta. - Oct. 2
University of Alberta – Edmonton, Alta. - Oct. 10
Lakeland College – Vermillion, Alta. - TBA
“We encourage all livestock sectors and industry partners to participate in the upcoming groups. We have planned them to be accessible to the majority of the province and hope to meet with a diverse cross section of our industry,” says Moggy.
About the Livestock Welfare Engagement Project
The project was requested and is being funded by Alberta Agriculture and Forestry. The insights and information collected through this project will be presented in a final report, which will be shared with the Government of Alberta to support its understanding of the animal welfare landscape in the province from the livestock industry’s perspective.
A significant issue for the poultry industry is the disposal of bird carcasses and manure when they are contaminated with avian influenza virus.
According to the "Highly Pathogenic Avian Influenza Response Plan" developed by the USDA, there is a clear need for better disposal technology.
One intriguing way forward is to heat the carcasses and manure in a mobile trailer to quickly react to outbreaks before they can spread. The trailer would hold multiple gasifiers, which would be used to heat up the trailer. From there, a conveyor system would take the carcasses and manure through the trailer until the virus is destroyed. The gasifiers use a solid fuel like seed corn or wood chips to provide the energy at very low cost and produce an in-situ charcoal bed that breaks down organic pollutants.
The University of Iowa has more than four years of experience in operating an industrial scale gasifier based on these principles and uses it in conjunction with lab testing and computer modeling to understand and predict general gasification behavior. The focus of this research project was to study the issues involved in trailer gasification and avian influenza virus elimination.
Project #BRU008: Analysis of Poultry Gasification Parameters for Elimination of Avian Flu Exposed Birds and Manure, was conducted by Dr. Albert Ratner, University of Iowa.
The project was recently completed by Ratner and colleagues in the Department of Mechanical and Industrial Engineering at the University. They developed the design for a mobile system to heat poultry carcasses and manure to inactivate avian influenza virus. This system could be utilized during an avian influenza outbreak to quickly help eliminate the virus from infected farms and better contain the spread of an outbreak.

The OIE has found Canada to be a top performing country and a leading example for meeting international veterinary service standards, with no major weaknesses. The full CVO's statement is available in its entirety on the CFIA's website.
The evaluation, conducted at Canada's request, was coordinated by the Canadian Food Inspection Agency (CFIA) and involved federal, provincial and territorial governments and representatives from the private veterinary sector, academia and veterinary regulators. The full Performance of Veterinary Services (PVS) Evaluation Report is available on the OIE's website.
The CFIA will be working with federal, provincial and territorial partners as well as representatives from the veterinary sector and the animal industry to further strengthen veterinary services across the country.
The CFIA continues to lead on other initiatives to improve animal health, veterinary public health and animal welfare in Canada.
"With the majority of Canada's veterinary services getting the top five out of five rating based on the OIE's international standards, and with the implementation of the OIE's recommendations, Canada will further strengthen its position as a global leader in promoting the health of animals and protecting the public from animal disease. This will also help strengthen international trade and economic opportunities," says, Jaspinder Komal, Chief Veterinary Officer and OIE Delegate for Canada.
This award is given to a student who is the senior author of an outstanding research manuscript in Poultry Science or The Journal of Applied Poultry Research, and only students awarded Certificates of Excellence for research presentations at an annual PSA meeting can compete.
Bortoluzzi’s winning paper — entitled “Sodium butyrate improved performance while modulating the cecal microbiota and regulating the expression of intestinal immune-related genes of broiler chickens” — evaluated the effect of sodium butyrate (SB) on performance, expression of immune-related genes in the cecal tonsils, and cecal microbiota of broiler chickens when dietary energy and amino acids concentrations were reduced.
The paper results confirmed that SB had positive effects on the productive performance of broilers fed nutritionally reduced diets, partially by modulating the cecal microbiota and exerting immune modulatory effects.
"Alltech is proud to sponsor this award, as innovation is the core of our business," said Dr. Kayla Price, poultry technical manager for Alltech Canada. “We support advancements in the poultry industry and encourage students to publish their research and communicate their discoveries, which can positively influence the future of poultry production."
Cristiano Bortoluzzi is a doctor of veterinary medicine and is currently pursuing a Ph.D. in the department of poultry science at the University of Georgia.
He grew up on a farm in southern Brazil with dairy cows, pigs and poultry, so his passion for animal production started when he was young and has influenced his career path.
Bortoluzzi completed several internships in his first year of vet school and found that poultry nutrition and health interested him the most.
Throughout his studies, he was actively involved in research trials, attended scientific meetings and learned about the intestinal health/immune system of broilers and the importance of nutrition.
While working toward his master’s degree, he spent three months working with the United States Department of Agriculture/Agriculture Research Service (USDA/ARS) in Indiana.
In January 2015, he started his Ph.D. in animal science at Purdue University, later moving to the University of Georgia. Bortoluzzi has published 18 papers and will finish his Ph.D. in the fall. He is looking forward to working in and contributing his expertise to the poultry industry.
Alltech has sponsored the Alltech Student Research Manuscript Award since 2000, recognizing young leaders in scientific innovation for their commitment to publishing and sharing their work within the poultry sector.
The Council also provided an update on its funding programs and activities and announced a new joint funding initiative.
This past March, AAC wrapped up its successful delivery of Growing Forward 2 (GF2) to Ontario organizations and collaborations. Close to 400 projects received funding of $33.9 million through this program over the last five years.
AAC is now responsible for delivering the Canadian Agricultural Partnership to Ontario organizations and collaborations. This federal-provincial-territorial initiative supports projects in three priority areas: Economic development, environmental stewardship, and protection and assurance.
Research and innovation are the key focus across the Partnership’s 19 project categories. Funding is available for a range of activities including applied research, pilots, assessments, planning, and market development.
“We want to encourage applications from Ontario organizations and collaborations across the sector to demonstrate that the need for the program is strong,” said AAC chair Kelly Duffy in her remarks.
AAC also delivers two programs targeted at the Ontario greenhouse sector: the $1 million Greenhouse Renewable Energy Technologies (GRET) initiative for the Ministry of Environment and the $19 million Greenhouse Competitiveness and Innovation Initiative (GCII) for the Ontario Ministry of Agriculture, Food and Rural Affairs.
How to better deal with livestock transportation emergencies, particularly truck rollovers, was behind a GF2 project Farm & Food Care Ontario (FFCO) completed in partnership with Beef Farmers of Ontario.
A needs assessment of stakeholders from farmers and transporters to government, first responders and animal organizations resulted in one-on-one training for first responders in how to specifically address livestock transport emergencies. An emergency response manual for producers was also created.
“The need to train emergency responders is huge and we appreciate the GF2 funding that helped us complete this project – this was a first step in helping address the issue of livestock transportation emergencies,” said FFCO Program Manager Bruce Kelly.
The evening wrapped up with an announcement of AAC’s joint initiative with Ontario Genomics. The Regional Priorities Partnership (RP3) Program, in partnership with Genome Canada, aims to promote the adoption of genomics-based technologies, tools and services within the Ontario agriculture and agri-food sector.
RP3 program materials will be available this September with applications due January 2019.
“I remain enthusiastic and optimistic about the Council’s future,” Duffy said in her closing remarks. “Opportunities for innovation are greater than ever and AAC can play an important role in assisting the industry as it moves forward.”
Many types of tools, equipment and devices gather data on everything from crop yields to how many steps an animal takes in a day. However, much of that data is underutilized because it’s collected by systems that don’t or can’t communicate with each other.
The need for better decision-making on farms through better data use resulted in Ontario Precision Agri-Food (OPAF), a partnership of agricultural organizations led by Ontario Agri-Food Technologies (OAFT) that’s developing an open agri-food innovation platform to connect and share data.
The goal, according to lead director Dr. Karen Hand of Precision Strategic Solutions, is getting data, wherever it exists (both data repositories in industry or government and data generated by countless sensors) so it can be used to help advance important food production issues like food safety, traceability and plant and animal disease surveillance.
For example, information about the prevalence and control of insect pests like cutworms that damage soybean crops lies with many different people and organizations, including university and government researchers, crop advisors, input suppliers and farmers.
“There is no single spot where all of the information about a particular pest can be accessed in a robust, science-based system and used in decision-making and that’s where OPAF’s platform will help,” Hand says.
Pilot projects are underway with Ontario’s grain, dairy and poultry producers to identify their needs in areas like crop protection, sustainability and food safety and how OPAF can provide data-driven solutions to benefit farmers.
“We sit down with farmers, advisors, associations, government and researchers to find out what data they have, where they exist and if we were able to connect them, what value or benefit that would offer participants – either specific to the commodity they are producing or on larger food-related issues such as food safety or impact on trade,” she explains.
And OPAF’s efforts are gaining global recognition. Earlier this year, Internet of Food and Farm 2020, a large project in the European Union exploring the potential of IOT technologies of European food and farming, recognized OPAF as one of three global projects to collaborate with.
“This is going to be changing the face of data enablement in Canada and contributing globally,” says Tyler Whale of Ontario Agri-Food Technologies (OAFT). “We are creating a platform that is the base of something new, and although we are piloting this in Ontario, it will be available nationwide to those who want to use it.”
OPAF partners include OAFT, University of Guelph, University of Waterloo, Niagara College, Vineland Research and Innovation Centre, Livestock Research Innovation Corporation, Ontario Fruit and Vegetable Growers Association, Grain Farmers of Ontario, Ontario Federation of Agriculture, Farm Credit Canada, Ontario Agri-Business Association, Bioindustrial Innovation Canada, and Golden Horseshoe Farm and Food Alliance.
This project was funded by Growing Forward 2, a federal-provincial-territorial initiative. The Agricultural Adaptation Council assists with GF2 delivery in Ontario.
The insights and information collected through this project will be presented in a final report, which will be shared with the Government of Alberta to support its understanding of the animal welfare landscape in the province from the livestock industry’s perspective. The Livestock Welfare Engagement Project was requested and is being funded by Alberta Agriculture and Forestry.
Your voice matters – Everyone encouraged to participate
“Livestock welfare is important to all industry stakeholders, as well as the bodies that regulate the sector, and practices continue to change and evolve. This project will provide every stakeholder – from individual farmers and ranchers to producer association groups, veterinarians and all others – the opportunity to share their insight into what is happening in their sector today,” says Annemarie Pedersen, AFAC executive director. “These diverse insights will be critical in creating a clear picture of the extensive work being done related to animal welfare in Alberta today, and in providing direction for the future.”
Industry input required
One of the most important parts of the project is the project survey. This survey is now online and is open to anyone in Alberta who is involved in animal agriculture in the province. Individuals and organizations of all kinds across the industry are invited and encouraged to participate. The survey is designed to incorporate four categories: 1) organizations, 2) abattoir & auction markets, 3) individuals (e.g. producers), and 4) students.

The survey is open until October 31st. Participants are encouraged to complete the survey as soon as possible. Any participants falling under more than one category are welcome to complete multiple surveys.
"Sharing and redistribution of this survey is requested. The more responses gathered, the clearer the final picture of Alberta’s livestock sector will be," says Pedersen. "Industry associations such as producer and commodity organizations are encouraged to circulate this information to their members and stakeholders and we encourage them to participate as well."
Key components of the overall project include a preliminary engagement consultation session (completed in March), the online project survey (now underway), focus groups (to follow) and development of the final report. If you have questions on which survey version to complete or on other aspects of the project, please contact AFAC.
