This is a key result coming from a recent Life Cycle Assessment (LCA) conducted by Groupe AGÉCO, a consultation firm specializing in corporate social responsibility and economic studies; the study was designed to measure the environmental and social performance of Canada's chicken sector, from hatching egg to processor.
The Environmental Footprint – Key findings
- Since 1976, environmental performance significantly improved because of major productivity gains and significant improvements in feed conversion ratio.
- Per kilogram of protein, the carbon footprint of Canadian chicken is lower than that of other livestock commodities produced in North America based on FAO's assessment of global livestock emissions.
- In the last 40 years, the carbon footprint of the sector was reduced by 37 per cent.
- Water consumption has been reduced by 45 per cent in the same timeframe.
- 62% of the entire sector's total energy use comes from renewable sources, with chicken feed accounting for the bulk of renewable energy consumption.
Canada's chicken farmers are committed to food safety & animal care: Canadian chicken farmers are certified on the mandatory Raised by a Canadian Farmer On-Farm Food Safety Program (OFFSP) and Animal Care Program (ACP), both of which are 3rd party audited.
After eliminating Category I antibiotics (the most important for human medicine) on the farm, Canada's farmers have committed to eliminating the preventive use of Category II antibiotics by the end of 2018 and a goal had been set to eliminate the preventive use of Category III antibiotics by the end of 2020.
Dedicated social license: Over 90 per cent of Canadian chicken farmers are engaged in their communities by providing free services to community members or by being engaged in municipal or regional organizations.
Competitive working conditions: Over 90 per cent of Canadian chicken farmers pay their workers a salary over the provincial minimum wage and about 70 per cent offer their employees benefits such as insurance and bonuses in addition to other benefits in kind.
A Pledge for Continual Improvement
For Canadian chicken farmers, sustainability means protecting animal health and welfare, ensuring worker and community wellbeing, preserving the health of the land and of Canadian farms and contributing to the Canadian economy by providing affordable food to Canadians.
Benoît Fontaine, Chair of Chicken Farmers of Canada affirms that, "Our sustainability journey is a process of continual improvement. We have come a long way with the implementation of on-farm programs, and with the growth in our industry which has contributed to the Canadian economy and helps support rural communities. But we'll always have more work to do and we will continually evolve to improve our practices and deliver on the expectations of Canadian consumers."
An LCA is an internationally recognized approach to assess the impacts associated with all of the stages of a product's life – in this case chicken. There is a well-established protocol for LCA subject to an ISO standardized methodology. LCAs can help an industry determine which aspects of their production are most efficient, and where they can improve efficiencies, reduce environmental impacts, or improve social interactions along their entire value chains.
The LCA provides the chicken industry with benchmarks for its impact on climate change, natural resources, biodiversity and ecosystem quality, and human health, while the social LCA provides a qualitative assessment of the industry's socioeconomic performance.
Conducting an LCA is part of our strategy to support our industry's work in maintaining consumer and buyer confidence that supply chain risks are adequately addressed. It can also improve industry's social licence and assurance to consumers that chicken is safe, and produced in an efficient and responsible way.
People care deeply about their food, about knowing where it comes from and that what they are serving to their family and friends is of the highest quality; our farmers and their families are no different. So when we say that the Canadian chicken industry is good for Canadians, it's because we know that we're raising our chickens to the highest standards: yours.

Iowa State University researchers are conducting experiments to determine what advantages may arise from integrating chickens into vegetable production systems.
The researchers must balance a range of concerns, including environmental sustainability, costs and food and animal safety. But Ajay Nair, an associate professor of horticulture and a vegetable production specialist for ISU Extension and Outreach, said finding ways to integrate vegetable and animal production may lead to greater efficiency and healthier soils.
The experiments, currently in their second year, take place at the ISU Horticulture Research Station just north of Ames. The researchers are testing what happens when a flock of broiler chickens lives on a vegetable field for part of the year.
The chickens forage on the plant matter left behind after the vegetables are harvested and fertilize the soil with manure. This integrated approach could reduce off-farm inputs and also provide producers with sustainable crop rotation options.
The researchers are testing three different systems on a half acre of land at the research farm. The first system involves a vegetable crop – one of several varieties of lettuce or broccoli – early in the growing season, followed by the chickens, which are then followed by a cover crop later in the year.
The second system involves the vegetable crop, followed by two months of a cover crop, with the chickens foraging on the land later in the year. The third system is vegetables followed by cover crops, with no chickens.
The experiment involves roughly 40 chickens, which live in four mobile coops that the researchers move every day. Moving the coops around ensures the chickens have access to fresh forage and keeps their manure from concentrating any particular part of the field. An electric fence surrounds the field to keep out predators.
Moriah Bilenky, a graduate assistant in horticulture, checks on the chickens every morning to make sure they have food and water. She also weighs them periodically to collect data on how efficiently they convert food into body mass. The researchers designed the trial to uphold animal health, and Bilenky said she keeps a detailed log on how foraging in the fields impacts the birds’ health and performance.
Nair said the researchers are looking at several facets associated with sustainability. Nitrogen and phosphorous deposited in the soil from the chicken manure could alleviate some of the need for fertilizer application, while working cover crops into the system can prevent the loss of nutrients into waterways. Economics must also factor into the research, he said.
“We might come up with results that really help the soil, but if the system is not economically stable, I doubt growers will be willing to adopt it because it has to work for their bottom line as well,” he said.
The trials also adhere to food safety regulations. For instance, all vegetables are harvested before the chickens are introduced to the fields, ensuring none of the produce is contaminated. The researchers consulted food safety and animal science experts at Iowa State while designing their experiments, and the work undergoes regular IACUC (Institutional Animal Care and Use Committee) inspection and documentation, he said.
The trials remain ongoing, so the researchers aren’t drawing any conclusions yet about the success of their integrated system. The project is currently supported through a SARE (Sustainable Agriculture Research and Education) grant. Nair said he’s seeking additional funding to investigate the animal health and integrated pest management aspects of this research.
So why did the chicken cross the road? It’s too early to tell, but maybe so it could get into the lettuce and pepper fields.
The three-year study is being performed to combat the 1.8 million tons of waste produced annually in Alabama from its $15 billion poultry industry.
Phosphorous-rich poultry litter is a big concern in Alabama and other states where the litter is used to fertilize fields. If the nutrient leaks into waterways, it can cause toxic algae blooms which can lead to deficient oxygen levels and destruction of life in the water.
The study will look at the Sand Mountain region of North Alabama and a row-crop field in Wisconsin, two large agro-ecosystems that are currently having issues with managing their phosphorous levels. | For the full story, CLICK HERE.
Through the renewed OMAFRA-U of G agreement, OMAFRA and U of G will build on world-class agri-food research, including new advances in artificial intelligence, big data analytics and precision agriculture.
“Scientific research is critical to developing innovations that benefit people, animals and the environment,” said U of G president Franco Vaccarino. Agri-food innovation also attracts investment and highly skilled talent, making the economy more robust, creating jobs and sustaining strong communities, he said.
The agreement brings together academia, government and industry to support and enhance Ontario’s agri-food sector through cutting-edge research and innovation.
The commitment to the agreement was renewed for another 10 years today during an event at U of G attended by leaders from industry, government, and academic institutions.
“The partnership has led to breakthrough discoveries and revolutionary advancements during the past two decades. It demonstrates the profound impact that government and universities can have when they work closely together with shared goals,” Vaccarino said.
“This novel partnership has positioned Ontario and Guelph as the epicentre of agricultural research and innovation in Canada, and supported industry development and growth – contributing billions to Ontario’s economy.”
Jeff Leal, Minister of Agriculture, Food and Rural Affairs and the Minister Responsible for Small Business, said, “Our government looks forward to continuing to partner with the University of Guelph to ensure Ontario’s agri-food sector is the most innovative and productive in the world, producing the highest quality and safest food for Canada and the world.”
Agri-food is a leading Ontario economic sector, contributing more than $37 billion to the province’s economy and employing more than 800,000 people.
As highlighted by Dominic Barton and the Advisory Council on Economic Growth, Canada can be a global leader in agri-food, with new value-added products, technologies, and solutions, said Malcolm Campbell, U of G’s vice-president (research).
He added that one of today’s great global challenges is safely feeding the world’s rising population while protecting the environment.
“It’s a hefty challenge, but U of G, as Canada’s food university, is up to the task. We have a 150-year legacy in agri-food and a reputation for innovation and discovery,” Campbell said.
The OMAFRA-U of G Agreement will provide the platform necessary to create new knowledge, and devise novel technologies and agricultural practices to produce safe, nutritious food while preserving biodiversity, animal welfare, and human health.
U of G is first in Canada and 14th in the world for agricultural science according to the U.S. News & World Report ranking of best global universities for agricultural sciences.
The Ontario Veterinary College is first in Canada, third in North America and sixth worldwide among veterinary colleges in a ranking by Quacquarelli Symonds, which names the world’s best universities in 46 academic subjects.
The University’s $77-million Food from Thought research project, funded by the federal government in 2016, is creating novel tools for producing more and safer food while also protecting the environment.
U of G and OMAFRA established an enhanced agreement in 1997; it was renewed for 10 years in 2008. The new agreement will take effect April 1, 2018.
Under the new agreement, the University receives up to $71.3 million a year to manage research and innovation programs and related facilities, including the Ridgetown Campus, the Agriculture and Food Laboratory program, the Animal Health Laboratory program, and 15 research stations and centres.
The Agreement also supports knowledge mobilization and commercialization.
Examples of innovations stemming from the OMAFRA-U of G Agreement:
- New detection methods and management systems for diseases such as avian influenza and biocontainment facilities. Researchers study highly hazardous food and animal-to-human pathogens and viruses such as West Nile virus and tuberculosis, and lower-level pathogens, such as coli 0157:H7, Salmonella and Listeria, in a safe and secure environment
- The world’s first compostable coffee pod, PurPod100, developed by a research team at U of G’s Bioproducts Discovery and Development Centre working with Club Coffee and Competitive Green Technologies

Researchers pitch their ideas to a panel of industry experts and business managers; winners receive grants to turn ideas and discoveries into a marketable product or technology
- Research on biocarbon and other unconventional fuels to improve efficiency and sustainability
- A natural formula, hexanal, to prolong the shelf life of fresh produce
- Smartphone applications that identify and control field pests
Alltech China has built long-term cooperative research relationships with 10 well-known universities, research institutes and leading feed and food enterprises.
“The Alltech China Research Alliance is focused on building toward a green agriculture future in China,” said Dr. Mark Lyons, global vice president and head of Greater China for Alltech. “The roadmap to this future requires practical solutions, which will be developed through advanced scientific research and technology and the powerful partnership of these leading agricultural minds.”
Defa Li, professor at China Agricultural University and academician at the Chinese Academy of Engineering, and Kangsen Mai, professor at Ocean University of China and academician at the Chinese Academy of Engineering, along with more than 30 other professors from agricultural colleges and research institutions, attended and spoke at the meeting, sharing the results of their latest research.
“This meeting of the alliance explored how to reduce antibiotic residues in food, how to effectively use limited resources in the midst of population explosion, and how to reduce water and soil pollution,” said Karl Dawson, vice president and chief scientific officer at Alltech.
A new mycotoxin detection method
The Institute of Agriculture Quality Standards and Testing Technology for Agro-Products of the Chinese Academy of Agricultural Sciences (IQSTAP) has established a method for the simultaneous detection of 21 mycotoxins, or their metabolite residues, in the plasma of animals. These include toxins such as aflatoxin B1. This testing is expected to become the agricultural industry standard for the detection of mycotoxins in China.
Recently, Alltech and IQSTAP published an article entitled "Liquid Chromatography-Tandem Mass Spectrometry for Simultaneous Determination of 21 Kinds of Mycotoxins or Their Metabolites in Animal Plasma." Dr. Ruiguo Wang of IQSTAP, who introduced the study, says that it established a liquid chromatography-tandem mass spectrometry method that simultaneously detects animal plasma aflatoxin B1 and 21 other kinds of mycotoxins or their metabolite residue.
Existing mycotoxin detection methods have very complex sample treatment operations, and high detection costs make it generally difficult to do a variety of simultaneous determinations of mycotoxins. The QuEChERS method (Quick, Easy, Cheap, Effective, Rugged, Safe) is a fast, sample pre-treatment technology developed for agricultural products. It uses the interaction between adsorbent filler and the impurities in the matrix to adsorb impurities to achieve purification.
In this study, 21 samples of mycotoxins and their metabolites in animal plasma were developed by liquid chromatography-tandem mass spectrometry (ICP-MS) based on the QuEChERS principle. The method is simple, rapid, low-cost and accurate. It can be used for combined mycotoxin animal exposure assessment and mycotoxin toxicokinetic study. Wang said this method has been submitted to the Ministry of Agriculture of the People’s Republic of China for review and is expected to pass as a fungal detector by agriculture industry standards.
Functional ingredients for better pork quality
Another breakthrough came from collaboration between Alltech and Jiangnan University to improve food safety and quality. A Jiangnan University research project showed that the addition of rapeseed selenium in the diet can improve the quality of pork, increasing its water-holding capacity and tenderness. An article published based on Alltech and Jiangnan University’s study confirmed that the additions of flaxseed oil and sesame selenium to the diet can improve pork quality, reducing drip loss by 58–74 percent. The organic selenium diets increased muscular selenium content up to 54 percent. Flaxseed oil and selenium can be used to alter the fatty acid structure of pork, increase omega-3 fatty acids and reduce the proportion of omega-6/omega-3 fatty acids in meat, which can lower the risk of cardiovascular disease in consumers.
Minerals matter: How trace minerals can impact pollution
Improper sewage treatment and greenhouse gas emissions are leading to heavy pollution of water, soil and air, and some small-scale farms have been closed because of this pollution.
"This will require improved feed conversion, which will reduce damage to the environment without affecting the performance of the animal," said Li.
Inorganic trace minerals in feeds have contributed to this environmental pollution. Due to their low absorption rates, 80–90 percent of inorganic zinc and copper will generally be excreted by the animal, contaminating water and soil.
Organic trace minerals, however, are absorbed more readily. Alltech’s Total Replacement Technology™ is a groundbreaking approach to organic trace mineral nutrition. It features products such as Bioplex®, which includes copper, iron, zinc and manganese, and Sel-Plex®, which includes selenium. Compared to conventional inorganic minerals, these formulations are better absorbed, stored and utilized by the animal and are thus able to meet the higher nutrient needs of modern livestock for rapid growth, maximum reproductive performance and animal health. Additionally, because they are absorbed more readily, less is excreted into the environment.
Some Chinese feed companies are already using Alltech’s Total Replacement Technology. In addition to aiding in animal performance and health, many customers have noted it improves the smell of pig farms.
The Honourable Bardish Chagger, Leader of the Government in the House of Commons and Minister of Small Business and Tourism, today announced a $1.9 million investment with the University of Waterloo to examine greenhouse gas (GHG) emissions associated with agricultural activities and the potential benefits of alternative land use practices and beneficial management practices (BMPs).
This project with the University of Waterloo is one of 20 new research projects supported by the $27 million Agricultural Greenhouse Gases Program (AGGP), a partnership with universities and conservation groups across Canada. The program supports research into greenhouse gas mitigation practices and technologies that can be adopted on the farm.
According to some early findings from a study by Penn State graduate student Erica Rogers, poultry producers are potentially lowering their impact on the Chesapeake Bay.
Rogers and fellow Penn State graduate student Amy Barkley discussed those initial findings from their two master’s thesis projects with the poultry service technicians attending Monday’s Penn State Poultry Health and Management Seminar at the Lancaster Farm and Home Center.
Her project’s goal is to accurately depict poultry’s contribution to the Chesapeake Bay Total Maximum Daily Load. The Chesapeake Bay “is one of the most studied watersheds in the world,” she said, but the problem with the current model is “they are using outdated information for poultry.”
Rogers built her work around the concept that poultry litter management has changed and farmers have adopted more precise diets for their flocks. READ MORE
Poultry sludge is sometimes turned into fertilizer, but recent trends in industrialized chicken farming have led to an increase in waste mismanagement and negative environmental impacts, according to the United Nations Food and Agriculture Organization.
Droppings can contain nutrients, hormones, antibiotics and heavy metals and can wash into the soil and surface water. To deal with this problem, scientists have been working on ways to convert the waste into fuel. But alone, poultry droppings don’t transform well into biogas, so it’s mixed with plant materials such as switch grass.
Samuel O. Dahunsi, Solomon U. Oranusi and colleagues wanted to see if they could combine the chicken waste with Tithonia diversifolia (Mexican sunflower), which was introduced to Africa as an ornamental plant decades ago and has become a major weed threatening agricultural production on the continent.
The researchers developed a process to pre-treat chicken droppings, and then have anaerobic microbes digest the waste and Mexican sunflowers together. Eight kilograms of poultry waste and sunflowers produced more than 3 kg of biogas — more than enough fuel to drive the reaction and have some leftover for other uses such as powering a generator. Also, the researchers say that the residual solids from the process could be applied as fertilizer or soil conditioner.
The authors acknowledge funding from Landmark University (Nigeria).
February 17, 2016 – New research has shown that tackling antibiotic resistance on only one front is a waste of time because resistant genes are freely crossing environmental.
Analysis of historic soil archives dating back to 1923 has revealed a clear parallel between the appearance of antibiotic resistance in medicine and similar antibiotic resistant genes detected over time in agricultural soils treated with animal manure.
Collected in Denmark – where antibiotics were banned in agriculture from the 1990s for non-therapeutic use – the soil archives provide an 'antibiotic resistance timeline' that reflects resistant genes found in the environment and the evolution of the same types of antibiotic resistance in medicine.
Led by Newcastle University, UK, the study also showed that the repeated use of animal manure and antibiotic substitutes can increase the capacity of soil bacteria to mobilize, or ready themselves, and acquire resistance genes to new antibiotics.
Publishing their findings in the academic journal Scientific Reports, the study's authors say the data highlights the importance of reducing antibiotic use across all sectors if we are to reduce global antibiotic resistance.
"The observed bridge between clinical and agricultural antibiotic resistance means we are not going to solve the resistance problem just by reducing the number of antibiotics we prescribe in our GP clinics,” said lead author David Graham, professor of ecosystems engineering at Newcastle University.
"To reduce the global rise in resistance, we need to reduce use and improve antibiotic stewardship across all sectors. If this is not done, antibiotic resistance from imprudent sectors will cross-contaminate the whole system and we will quickly find ourselves in a situation where our antibiotics are no longer effective."
Antibiotics have been used in medicine since the 1930s, saving millions of lives. Two decades later, they were introduced into agricultural practices and Denmark was among the leaders in employing antibiotics to increase agricultural productivity and animal production.
However, a growing awareness of the antibiotic resistance crisis and continued debate over who and which activities are most responsible led to the EU calling for the use of antibiotics in non-therapeutic settings to be phased out and Denmark led the way.
The Askov Long-Term Experiment station in Denmark was originally set up in 1894 to study the role of animal manure versus inorganic fertilizers on soil fertility.
Analyzing the samples, the team – involving experts from Newcastle University, the University of Strathclyde and Aarhus University – were able to measure the relative abundance of specific β-lactam antibiotic resistant genes, which can confer resistance to a class of antibiotics that are of considerable medical importance.
Prior to 1960, the team found low levels of the genes in both the manured soil and that treated with inorganic fertilizer. However, by the mid 1970s, levels of selected β-lactam genes started to increase in the manured soils, with levels peaking in the mid 1980's. No increase or change was detected in the soil treated with inorganic fertilizer.
"We chose these resistant genes because their appearance and rapid increase in hospitals from 1963 to 1989 is well-documented," explains Professor Graham.
"By comparing the two timelines, we saw the appearance of each specific gene in the soil samples was consistent with the evolution of similar types of resistance in medicine. So the question now is not which came first, clinical or environmental resistance, but what do we do about it?"
Following the ban on non-therapeutic antibiotic use in Danish agriculture, farmers substituted metals for antibiotics, such as copper, and levels of the key β-lactam genes in the manured soils declined rapidly, reaching pre-industrialization levels by 2010.
However, at the same time the team measured a 10-fold rise in Class 1 Integrons. These are gene carrier and exchange molecules – transporters that allow bacteria to readily share genes, including resistance genes.
These findings suggest the application of manure and antibiotic substitutes, such as copper, may be 'priming' the soils, readying them for increased resistance transmission in the future.
"Once antibiotics were banned, operators substituted them with copper which has natural antibiotic properties," explains Professor Graham.
"More research is needed but our findings suggest that by substituting antibiotics for metals such as copper we may have increased the potential for resistance transmission.
"Unless we reduce use and improve stewardship across all sectors – environmental, clinical and agricultural – we don't stand a chance of reducing antibiotic resistance in the future."
May 17, 2013. The Honourable Gary Goodyear, Minister of State (Science and Technology), has announced that seven innovative environmental projects will benefit from more than $32 million in research funding over five years, via the new Climate Change and Atmospheric Research (CCAR) initiative. The funding will support teams composed of university researchers, scientists and partner organizations who will work together to advance the understanding of risks related to climate change.
"Our government is supporting research related to climate change through the creation of the Climate Change and Atmospheric Research initiative," says Goodyear. "We are confident that the knowledge generated through these projects will help improve the quality of life of all Canadians."
