Highlights from the George Foxcroft Reproduction Workshop at Leman 2024

On September 21^st, 2024, Jennifer Patterson and Michael Dyck hosted the “George Foxcroft Reproduction Workshop” at the Leman Conference in St.Paul, Minneosta. The workshop had an exciting line-up of world class speakers that addressed the theme “Managing the breeding herd in a changing environment”. We were pleased to have one of our biggest attendances to date, drawing in over 100 people from 14 different countries and from a number of industries (production, academia, media, nutrition, genetic services, consulting, sales).

We always measure the impact of the workshop, not only by the number of people in the room, but by the number of sows represented. This year, over 1.4 million sows were touched by people working directly for production companies, not including the many others that will have an influence.

The goal of these sessions is always to bridge the gap between science and practice and to foster networking opportunities for attendees. We accomplished this and hope that every attendee was able to take home valuable insights that they can implement in their own systems.

Special thanks to the University of Minnesota for their 18 years of partnership in organizing this workshop, and to Merck for their continued sponsorship and collaboration in designing this well-received program.

The presentations will be posted, please check back in the future.

“The management of an efficient breeding herd must take into consideration a variety of ‘environments’, including the animals’ physiological environment, the housing environment, the regulatory environment and the technological environment, just to name a few. These ever-changing environments that affect production are driving the need for more sophisticated and adaptable management practices. In this session we will bring together experts to discuss technical and practical considerations in dealing with these evolving environments and how to maintain an efficient breeding herd. This workshop is designed for swine producers, veterinarians, and industry professionals looking to enhance their knowledge and practices in swine breeding management. Don’t miss this opportunity to learn from the best and network with peers in the industry.”

The “last mile” – delivering research results to the people who can make the difference

Gentec works closely with industry partners in making a difference on farm. Jennifer Patterson is at the forefront of improving pork production efficiency. It was very pleasing to receive recent positive feedback from a partner that these efforts deliver key learning “to the people in the barn who can make the difference in performance”.

This aligns directly with RDAR’s commitment to delivering research outcomes that make a meaningful impact on Alberta’s economy and landscape, referring to this as the “last mile” in the delivery and uptake of research results. RDAR CEO, Dr. Mark Redmond emphasized this at a meeting RDAR hosted in Lacombe on November 18th. The aim was to bring producers, researchers, agri-businesses and municipal leaders together “to learn about funding opportunities, what practices are being adopted on-farm, and what research is underway to drive improvements in central Alberta’s agricultural practices”.

Putting tools in the hands of barn staff, as Jennifer does, is maybe an example of the “last quarter or even furlong”. Thank you once again to all Gentec’s partners who make these things happen.

In the field

Our project: “Using genomic tools to reduce GHG & Methane in beef cattle” is ramping up, so the team–Gentec and collaborators– went out to Roy Berg Kinsella Research Ranch to learn how to operate the Greenfeed Emissions Monitoring equipment. This equipment measures the enteric greenhouse gas emissions from cattle. Animals put their head into the gas measurement shroud to receive feed pellets. The animal’s RFID is then read, and as they are feeding, the enteric gases (CH₄, CO₂, H₂) and air are drawn up a sampling tube by positive air flow to an infrared sensor that quantifies gases. This enteric gas data will also provide a baseline for developing models for predicting enteric methane from fecal NIRs spectra. Some of the team also took in a web-based training to see how the data is collected, analyzed and reported by the C-lock software and analytics team. This latter aspect is an international collaboration with Belgian scientist Dr. Amélie Vanlierde with Walloon Agriculture Research Centre (CRA-W, Gembloux, Belgium) and French scientist Donato Andueza from The French National Research Institute for Agriculture, Food and Environment (INRAE).

As global and national pressures to enhance the sustainability and efficiency of beef cattle production continue to grow, the Canadian beef industry requires a multifaceted approach to address these challenges. One promising and enduring solution lies in leveraging genetic and genomic technologies to enhance breeding strategies. By selecting for beef cattle with improved feed efficiency, producers can reduce feed resource use, lower emissions, and maintain the same level of production.

The focus of this research was to investigate the functional genetics underlying feed efficiency in Canadian beef cattle and identify functional SNP markers associated with this trait. Selecting for feed efficient (FE) cattle, measured by Residual Feed Intake (RFI; kg/d), has the potential to increase lean meat yield without requiring additional feed. Using RNA-Sequencing technology, we uncovered genetic mechanisms driving feed efficiency by identifying key regulatory genes, functional SNP markers, and associated QTLs. This approach enables the detection of genetic mutations (SNPs) derived from DNA sequence data that may influence feed efficiency, providing valuable insights for improving sustainability in beef production.

A population of 48 Canadian beef cattle from the Roy Berg Kinsella Research Ranch (Alberta, Canada), including 16 Angus, 16 Charolais, and 16 Kinsella hybrid composite animals were selected from a larger cohort of 738 cattle based on their extreme FE phenotypes. At slaughter, rumen papillae tissue was collected from each animal for RNA extraction.

The study identified 11 key regulatory genes (EIF4B, USP43, RHOD, SERPINB2, MYH1, MYL2, TCEANC, CKM, MYLPF, TNNC2, and ENSBTAG00000040518) that were significantly differentially expressed between high and low FE groups. These genes were linked to muscle contraction and muscle cell biological processes.

Analysis of functional SNPs revealed 1,137 uniquely fixed SNPs in the high FE group and 1,190 in the low FE group across breeds. When examining the co-localized QTL classes overlapping with these functional SNPs, we found distinct patterns:

• High FE SNPs evenly overlapped with four major QTL classes: Meat and Carcass (18.19%), Milk (27.34%), Reproduction (23.95%), and Production (27.08%), with a smaller proportion overlapping with Health (1.87%) and Exterior (1.57%).
• Low FE SNPs predominantly overlapped with Milk QTLs (59.65%), followed by Meat and Carcass (7.91%), Reproduction (14.95%), and Production (11.61%), with a smaller proportion overlapping with Health (2.83%) and Exterior (3.05%).

These findings suggest that less feed-efficient cattle may allocate more energy toward milk-related traits, while more feed-efficient cattle direct energy toward performance traits, such as meat production and yield. Selecting for higher feed efficiency in beef cattle could thus optimize energy partitioning for production-related traits, benefiting the beef industry.

The results of this research were presented at two major conferences and at the Ontario Beef Field Day:

• The American Society of Animal Science – Canadian Society of Animal Science – Western Section ASAS (ASAS-CSAS-WSASAS) conference in Calgary, Alberta, in July 2024.
• The European Federation of Animal Science (EAAP) conference in Florence, Italy, in September 2024.
• The Ontario Beef Research Centre (OBRC) Beef Field Day in Elora, Ontario, Canada in October 2024.

Congratulations to Gentec alumna Kristin Lee on obtaining her PhD from the University of Guelph in September. Her thesis, titled “Python Based Genetic Evaluation System for the Improvement of Multi-Breed and Crossbred Beef Cattle”, was co-supervised by Professor Angela Canovas and Professor Flavio Schenkel. The project was supported by AgSights, who contributed both funding and valuable industry knowledge. She is now working for Gentec’s partner Genesus Genetics Technologies Inc. in the role of geneticist, where she focuses on optimizing their genomic evaluation software and overseeing genetic improvement programs in nucleus farms.

One of the longest serving members of Gentec, Prof. Leluo Guan, continues from strength to strength following her move to University of British Columbia where she continues her world leading research program to study rumen microbiome and its roles in cattle production. Recent new grant funding includes “Novel and adaptive rumen microbiome targeted solutions for GHG mitigation in cattle”  as results of long -term collaborations among Gentec (University of Alberta), University of Guelph, University of Manitoba, and AAFC. This project is funded through NSERC Alliance through “NSERC-SSHRC Sustainable Agriculture Research Initiative (SARI)”.

In summer 1991, BA student JC Cahill found himself walking throughout the coastal estuaries of Connecticut. It was an undergraduate research project within Craig Schneider’s lab at Trinity College, Conn that set him on a hunt for some elusive green algae.

“It was beautiful,” he remembers. “Being on the water… working with plants … and realizing professors don’t really have a boss and have great job security! It was then I naively decided that was the career path for me.”

During his PhD at the University of Pennsylvania, he gained a deep interest in grassland ecosystems, and the below-ground interactions that were very poorly understood at the time.

“We didn’t have genomics tools; we didn’t know what was happening in the soil so every question was new and likely important,” he remembers.

Now a Professor of Biological Sciences at UAlberta (since 1999), JC focuses on Alberta’s grasslands, and has a long history of research at the Kinsella and Mattheis ranches.

“I’m a researcher first,” he points out. “But I also really care about teaching and mentoring students.” (Ed. note: JC was awarded the 2023 Killam Award for Excellence in Mentorship, UAlberta’s most prestigious award for mentorship.)

He’s also a botanist. He has a whole other program focused on plant behaviour, how plants make decisions with their roots, interact and find food. That falls under behavioural sciences. And, depending on the task, he’s a microbiologist as well.

“Ecologist would be a good umbrella term for my research interests,” he says. “Or simply biologist.”

It’s this diversity of interests and disciplines that makes his lab attractive to the next generation of scientists.

“I have a general policy that no grad students should work on the same question at the same time,” he insists. “Because of that, the group has lots of diverse themes, including grasslands ecology, plant behaviour, and general studies of the maintenance of biodiversity and how ecological systems function.”

Most recently, his lab group has more explicitly included cattle and grazing into their research. Cattle are critical to maintaining grasslands in Alberta, although their direct and indirect consequences are less well understood than anticipated.

“As grassland ecologists, we realize that if we want to understand plants, carbon storage, and healthy ecosystems, we have also to understand the critical role played by the large herbivores of the system.”

Although JC has worked with Gentec-associated researchers Ed Bork and Cameron Carlyle for over a decade, it was more recent engagement by Gentec CEO Graham Plastow that really helped him see the potential value and need for a more holistic research program.

“The questions about the ecological impacts of grazing are more explicit now in my research, as is a clear understanding of the need to understand the consequences of forage production and other critical aspects of livestock production,” says JC. “The science isn’t as well developed on viewing grazing systems as a whole agricultural ecosystem. Instead, the focus has typically been on studying one part at a time (plants or soils or cattle). We are moving to a more holistic view to get a better balance out of these systems long term.”

That explains the diversity of interests but what about kicking those tires?

“My research group loves experiments,” explains JC. “There’s a lot of math theory in ecology that I struggle with; I’m not convinced it necessarily reflects reality or how it’s useful. That doesn’t stop it being influential in academic ecology. We prefer to test assumptions rather than argue about their accuracy. That way, we can see what holds up and what doesn’t. So we go into the field, manipulate something (kick the tire) like defoliation, resources or water, and measure plant, animal and diversity responses. Then see what falls off so we can refine the idea.”

JC is going to spend a lot of time on the CAT-G project ($6.3 million, funded by Genome Canada, RDAR and other partners), of which he and Carolyn Fitzsimmons (AAFC/UA and a Gentec-associated researcher) are co-leads. The project takes this holistic view of the grazing ecosystem, testing the impacts of adaptive multi-paddock grazing systems on plant, soil, microbe and cattle responses, all with an eye towards soil C storage, GHG production and critical animal production metrics. As part of this work, the team aims to develop bio-indicators of carbon cycling in grasslands to help enhance carbon markets by identifying climate-smart management actions. Tools like this could record changes in soil carbon storage and lower GHG emissions on grazed land much sooner than waiting for the soil carbon to accumulate and stabilize.

“We don’t believe that environmental gains have to come at an economic cost to producers,” points out JC. “The CAT-G project starts from a place where both can be achieved, kicking those tires and tying the knowledge into Gentec and other groups that will benefit from our data. It’s important to facilitate collaborations. Just as Gentec facilitated this project. Because there won’t be just one solution that works in just one place.”

On December 11, 2023, CAPI hosted a webinar supporting its latest report: Forces Impacting Animal Agriculture in Canada: A Synthesis with Gentec-associated researchers Tim McAllister (AAFC) and Ellen Goddard (UAlberta) among the panelists who discussed the common challenges and opportunities surrounding sustainability in animal ag. Here’s a summary of their comments.

TYLER MCCANN, CAPI’s Managing Director reported that Canada’s livestock sector should be thriving thanks to a dedicated land mass, economics and efficiencies—but instead faces difficulties mainly due to the challenging policy environment. CAPI’s white paper, Forces Impacting Animal Agriculture in Canada: A Synthesis, was developed to inform the policy environment.

BRUCE SCHUMANN, Director of Sustainability, Regulatory and Quality Assurance at GVF Group of Companies stated that one of GVF’s roles was to empower farmers to produce meat, milk and eggs profitably. Livestock are being villainized because of methane emissions but Canada is already one of the most sustainable and most efficient producers in the world. We need to embrace and communicate that reality to the public and to our leaders, and to help other nations be more sustainable for the good of the world.

AL MUSSELL, CAPI’s Director of Research, summarized the report, confirming that ag is 10% of Canada’s emissions, and animal ag is about 50% of that. Over time, animal emissions have declined, consistent with the decline in the cow herd. Canada is also an efficient producer of feed. But there are complications. Emissions are not limited to GHGs but include nitrogen into the water table, phosphorus in the water and coliforms. Measures to reduce GHGs will not necessarily reduce those as well. Ruminants, especially, are governed by a biogenic carbon system that is circular. It is not NEW methane into the system. It should still be reduced because it is an important GHG but it is possible that the contribution of animals may have been exaggerated. Less animals on the grasslands impair the grasslands, yet the productive capacity of ruminants is conversely impaired without the grasslands. We cannot simply intervene at one level. So where does this leave us. The world has a food security problem and a climate change problem. Canada is one of the few countries that can influence both. How do we move to food policy that addresses that?

Source: CAPI Webinar, December 11, 2023

TIM MCALLISTER, Principal Research Scientist, Ruminant Nutrition & Microbiology (AAFC) reminded participants that climate change issues have been around since the Nineties. What is changing is a new appreciation for the systems approach like the interaction between livestock and their impact on biodiversity. No one scientist has the expertise to do that.

On December 10, 2023, the Government of Canada announced a new economic incentive to reduce methane emissions from beef cattle. Emerging technologies such as diet formulations and bringing animals to the finishing phase faster will help.

Information and databases are getting stronger, and there are more open data available. All countries need to pull together to make a difference, just like for COVID-19. Even regulatory agencies are sharing knowledge and pathways to assessment. It is not likely that one technology will work for all conditions. Technologies exist for animals in confinement but not for rangelands so work is going on there. So it is a sector by sector assessment.

ELLEN GODDARD, Distinguished Fellow (CAPI) said that, as the science gets more complicated, public perceptions are more nuanced and can be confused by the seemingly conflicting messaging from different directions. They look for ways to simplify their decisions by listening to those they trust (farmers, some NGOs and scientists). They want to be able to compare product A with product B on environmental impact or health impact, for example, at the store. Those common standards are not available yet so people are frustrated.

Record-keeping to monitor impacts that can be used consistently in labelling will engender costs. If consumers are paying $10 for ground beef today, will they pay $12 if it has a sustainability label? In fact, they might stop being willing to pay the $10 if the information is not available. Providing the information  may be the cost for the industry to stay in the market, even at the original $10 price. Paying the same or more are all parts of the same decision to purchase the product.

The public remains cautious about genetic tools if called genetic modification but less so about other genetic technologies, and they desperately want those technologies used to improve animal health, their health and the environment. But a number of messages about how and why genetic technologies are used need to be distributed to get there.

KATHLEEN SULLIVAN, Vice President Government & Industry (Maple Leaf Foods) said that Maple Leaf was the world’s first carbon-neutral food company. Led by CEO Michael McCain, it created a blueprint and identified pillars to focus on: community, environmental security, animal welfare, food safety among them. The company is obliged to deal with the fact that it is an environmental protagonist. Generally, the public doesn’t realize that the company is made up of farmers (plant protein, poultry and pork). It owns and operates 200 hog farms and five feed mills, mostly in Manitoba. For pork, it runs the entire process from production to sales and international trade because it makes the company more reliable in terms of its footprint, how it is addressed and how all the pieces fit together. In 2019, Maple Leaf committed to reducing GHG emissions by 30% by 2030 (current carbon neutrality comes from buying carbon offsets and insets). That means dealing with manure in-house to reach the desired result. In Manitoba, the solution costs $0.5 billion and involves coordinating a lot of enterprises and players. The conversation is how to bring people together to do that.

RYDER LEE, General Manager (Canadian Cattle Association) said that defending cattle and sustainability is a local, national and international conversation. That entails producers working together, funding research on best practices, sending the CCA to engage with the Canadian Roundtable for Sustainable Beef, and going to COP28 in Dubai. There, we hosted events on sustainability in Canada and on the grasslands.

Canada’s competitors are knocking at the door or at customers’ doors, asking what is being done, measured, and its impact. The National Beef Sustainability Assessment, first done in 2016, benchmarks the environmental, social and economic performance of the Canadian beef industry. It highlights the areas where industry is doing well and identifies opportunities for improvement. CCA also looks at peer-reviewed science on the gamut of environmental services, asking questions such as how are measurements done, what the measurement burden is and how to incentivize producers to make changes.

OVERALL TAKEAWAY MESSAGE. Canadian animal agriculture has among the lowest emissions intensities in the world. Policies that integrate sustainability, food security and growth can help meet climate targets, and build Canada’s comparative advantage.

In the ever-evolving landscape of agriculture, the future of cattle herds hinges on strategic planning and embracing cutting-edge technologies. Among these technologies, genomics stands out as a powerful tool that can revolutionize the way we manage and optimize our cattle herds. This month’s At The Grill feature by William Torres (storyteller, empathetic connector and resonate catalyst) exploresthe importance of planning for the future of your cattle herd, with a specific focus on the transformative role that genomics can play.

Genomics—the study of an organism’s complete set of DNA, including genes and their functions—has become a game-changer in the realm of agriculture. In the context of cattle herds, genomics information offers unprecedented insights into the genetic makeup of individual animals. This wealth of information allows farmers and ranchers to make informed decisions about breeding, health, and overall herd management.

Precision Breeding for Desired Traits

One of the primary advantages of integrating genomics into cattle-herd planning is the ability to engage in precision breeding. Traditional breeding methods are effective but time-consuming, often requiring several generations to achieve desired traits. Genomics information accelerates this process by enabling the identification of specific genes associated with desirable traits, such as milk production, disease resistance, and meat quality. By selecting animals with the desired genetic markers, farmers can optimize breeding programs to enhance overall herd quality. Precision breeding boosts productivity and contributes to the sustainability of the herd by reducing the environmental impact associated with larger, less efficient populations.

Disease Resistance and Health Management

Genomics also plays a crucial role in fortifying the health of cattle herds. Through genetic screening, farmers can identify animals with inherent resistance to certain diseases. This information allows for the development of resilient herds that are better equipped to withstand common health challenges. Furthermore, genomics aids in the early detection of potential health issues. By analyzing an individual animal’s genetic code, farmers can assess susceptibility to specific diseases, enabling proactive health management strategies. Early intervention ensures the well-being of individual animals and prevents the spread of diseases within the entire herd.

Optimizing Feed Efficiency and Environmental Impact

In an era where sustainability is a key concern, genomics contributes to the optimization of feed efficiency, directly impacting the environmental footprint of cattle farming. By identifying genetic markers associated with efficient nutrient utilization, farmers can select animals that thrive on less feed while maintaining optimal growth rates. Reducing the overall feed requirements of a herd minimizes operational costs and mitigates the environmental impact associated with large-scale livestock farming. Genomics insights empower farmers to make ecologically-conscious decisions, fostering a more sustainable and responsible approach to cattle-herd management.

Long-term Economic Viability

Strategic planning for the future of a cattle herd involves considering economic viability. Genomics provides a pathway to increased profitability by enabling farmers to make data-driven decisions that enhance overall herd performance. Investing in genetically-superior animals leads to higher-quality products, whether it be milk, meat or other by-products. These premium products command higher prices in the market and contribute to the establishment of a reputable brand. By planning for the future with genomics, farmers can secure a competitive edge in the industry, ensuring long-term economic sustainability.

Challenges and Considerations

While genomics offers immense potential, it is crucial to acknowledge the challenges associated with its implementation. Initial costs, data management, and ethical considerations are among the factors that require careful attention. However, as technology advances and becomes more accessible, these challenges are likely to diminish, making genomics an increasingly integral aspect of cattle herd management.

Conclusion

Planning for the future of your cattle herd is a multi-faceted endeavour that demands foresight and adaptability. Embracing genomics as a cornerstone of your strategic planning positions your operation at the forefront of innovation and ensures the long-term success, health, and sustainability of your cattle herd. As the agricultural landscape continues to evolve, those who leverage the power of genomics will undoubtedly shape a future where efficiency, resilience, and profitability coexist harmoniously in the world of cattle farming.

If you’re a commercial beef producer in Western Canada, generally speaking, you’ve got a herd of crossbred cows. That means Gentec’s Replacement Heifer Profit Index (RHPI) Score™ should be one of your go-to tools. Why? It speaks to selecting replacement heifers with an optimal level of hybrid vigour, fertility, longevity and lifetime productivity.

A study (as reported in The Western Producer) led by Jared Decker at University of Missouri-Columbia, tells a good news story about the sires’ gEPDs and the predicted outcome in the feeder progeny. Using an Angus database as a starting point, Jared found relationships between sire gEPDs and the outcome in commercial cattle, giving the GeneMax tool a suite of gEPDs for weaning weight, carcass weight, marbling, ribeye area, among others. But… all for Angus crossbred cattle, and not for feed efficiency.

What does Gentec do differently?

“We didn’t want to repeat what each breed association would do so we concentrated on crossbred females mated to purebred and crossbred bulls common to western Canada. This also included the crossbred offspring, and was our starting point. Commercial cattle first,” says John Basarab, Gentec’s Director of Beef Operations. “So our database has a high percentage of Angus, Simmental, Charolais, Limousin, Hereford, Gelbvieh and other crossbred females and feeder cattle offspring. And our purebred database (bulls) for determining genomic breed composition and retained heterozygosity has 14 breeds. That’s quite different right off the bat.”

While the GeneMax tool concentrates on growth and carcass traits, it’s missing something that Gentec has been working on for over 20 years: feed intake and feed efficiency or dry matter intake (DMI) and residual feed intake (RFI). So again, Gentec’s reference database contains lots of phenotypes with genotypes for DMI and RFI, from which it developed molecular breeding values (MBVs) for DMI and RFI that most other genetic evaluation companies and breed association don’t presently offer.

Another key difference has to do with replacement heifer selection. Breeding values and maternal indexes for most purebred associations select for the genetic merit of the daughters produced from the sire and dam. Trait gEPDs in the maternal index usually include calving ease, growth traits (e.g., wean weight, direct and maternal milk, residual ADG), and heifer pregnancy. But that’s down the road quite a bit. The female calf has to be born from a single, unassisted birth early in the calving season, grow well from birth to yearling, and be from a mother with many retained daughters in the herd. But the line on the 50-year genetic trend for heifer pregnancy EPD is flat (!!) indicating not a lot of progress made. So Gentec has focused on the immediate need of selecting for PRESENT replacement heifers, not future daughters. In that case, hybrid vigour is very important, especially since, as identified by Gentec’s RHPI Score, it’s related to higher pregnancy rates and lifetime productivity.

“Clients have been “fascinated with the breed composition and gEPDS. It’s been an invaluable asset for our consulting practice and is adding value for the customer,” says Waylon Wise, veterinarian and owner of Cow/Calf Health and Management Solutions.

Most genomic evaluations concentrate on the “additive” genetic effect, where a single nucleotide polymorphism (SNP, pronounced “snip”) with 2 B alleles is better than 1 B allele, and better than no B alleles at all. This approach is particularly effective for moderate to moderately-high heritability traits like growth, feed efficiency, behaviour and carcass traits. However, traits with low heritability (like fertility and general fitness) are more influenced by the non-additive genetic effects of dominance, epistasis and genomic diversity, all related to hybrid vigour. General health and resilience to environmental stress (that is, hybrid vigour) are becoming more important, especially in the context of our rapidly-changing climate where animals need to be more resilient to extremes. This is an important component of Gentec’s index score.

“We concentrate on commercial crossbred cattle,” says John. “Then on providing what that producer is asking for—a replacement heifer that gives a calf during the first calving season at 2 years of age and stays in the herd for at least 5-years… a very tall order. We know that commercial producers don’t keep the best of records, and they definitely don’t keep pedigree information. Doing things using DNA or from a genomics point of view just has many advantages.”
