New Genetic Evaluation Tool for Hoof Health

A genetic evaluation tool for Hoof Health is now available for the Holstein breed. The tool promotes increased resistance to eight key foot lesions.

The selection for Hoof Health index was made possible through a research project financed under the Dairy Research Cluster 2 (a partnership between Dairy Farmers of Canada, Agriculture and Agri-Food Canada and the Canadian Dairy Network (CDN)) that spanned from 2014 to 2017, targeted at improving hoof health in Canadian dairy herds. After only one year since the project’s completion, CDN is able to transfer the research to the field with genetic evaluations for Hoof Health.

Two other key outcomes from the research project were also delivered. The first is the development of a data collection pipeline from hoof trimmers, to Canadian DHI, and then on to CDN, where it is stored in a national database. The second outcome includes the development of an interactive DHI hoof health management report, which will be available to dairy farmers in the coming months.

From Genetic Evaluations for Digital Dermatitis to an Overall Hoof Health Index

Genetic selection for increased resistance to Digital Dermatitis has been possible since December 2017. The new Hoof Health (HH) evaluation will replace Digital Dermatitis as the primary selection tool – a logical transition since Digital Dermatitis is one of the eight lesions that make up the Hoof Health index. The full list of lesions included in Hoof Health are included in Table 1. The frequency of Digital Dermatitis is the highest among the eight lesions, at approximately 17%. Of cows presented to the hoof trimmer, 46% experience at least one hoof lesion in their lifetime.

Table 1: Frequencies, Heritabilities, Correlations and RBV Translation for the Eight Hoof Lesions Included in the Hoof Health index
Lesion Frequency (%) Heritability (%) Correlation with Hoof Health index (%) Expected % increase in Healthy Daughters for each 5 point increase in Hoof Health
Digital Dermatitis 16.9 8 85 4.6
Interdigital Dermatitis   2.6 5 70 0.9
Heel Horn Erosion   2.9 8 76 0.1
Sole Ulcer   8.5 5 74 3.0
Toe Ulcer   1.3 4 3 0.5
White Line Lesion   4.7 4 9 1.4
Sole Hemorrhage   7.4 3 63 0.9
Interdigital Hyperplasia   2.2 7 40 1.1

The heritability of each individual lesion is included in Table 1, ranging from 3% to 8%. The heritability of the overall Hoof Health index is 9%, meaning 9% of the variation for hoof lesions seen in Holsteins can be attributed to genetics. Correlations of the individual lesions with the overall Hoof Health index are also presented in Table 1. Infectious lesions like Digital Dermatitis, Interdigital Dermatitis and Heel Horn Erosion have high correlations with Hoof Health. The correlations between Hoof Health and the non-infectious lesions like Sole Ulcer, Toe Ulcer, White Line Lesion, Sole Hemorrhage and Interdigital Hyperplasia are more variable. Toe Ulcer and White Line Lesion have the lowest correlations with Hoof Health since they each have a small negative genetic correlation with the three infectious hoof lesions.

Overall, the correlation between Hoof Health and both the Lifetime Profit Index and Pro$ is 58%, meaning selection for either national index will result in improvement for Hoof Health.

In the coming months, a separate Relative Breeding Value for each of the eight lesions will appear on the CDN website when selecting the “Health” tab for any Holstein sire.

Genomics and Feed Efficiency: Local research with global implications

By Emilie Belage, University of Guelph in collaboration with Dr. Filippo Miglior, Canadian Dairy Network and co-PI on the project entitled, Increasing feed efficiency and reducing methane emissions through genomics: A new promising goal for the Canadian dairy industry.

The field of genomics has the potential to not only improve the dairy industry at the herd level, but it has implications at national and global levels. A cutting-edge Canadian initiative, led by Dr. Filippo Miglior, of the University of Guelph, in collaboration with Dr. Paul Stothard, of the University of Alberta, seeks to understand how genomics impact feed efficiency and reduce methane production in dairy cattle in a 10-year project launched in 2015. Thanks to the relationship between producers and researchers involved in this project, the researchers and industry expect producers will be able to select for more efficient, less costly animals, while preserving the environment for future generations.

original_424459801What is genomics? 

Genomics is the study of the entirety of genes in a living organism. It helps us understand how genes interact to produce growth and development in an animal or plant. In dairy cows, it helps producers identify which cows have desirable traits, like high production, good reproduction or longevity, which can be passed onto offspring.


Importance of genomics and feed efficiency for producers and the planet

Feed is one of the main costs on a dairy farm. Having cows that can convert feed into milk more efficiently is beneficial for the bottom-line and the environment: farmers can select and breed for cows that produce more milk with less feed. What this also means, is that fewer crops need to be grown to feed the same number of animals, potentially freeing cropland for other purposes. Cows that eat less also produce less manure and less methane, an important greenhouse gas (GHG). This is not only important for manure management, as there is less manure that needs to be stored, but it also has implications on the environmental footprint dairy farms have today.  Food production that is environmentally sustainable is becoming more and more important for consumers. There is increased concern and awareness of how the agricultural sector contributes to GHG emissions like methane, and its role in global warming. Dairy farmers’ investment in this research is innovative – by selecting for cattle that produce less methane, dairy farmers can do their part in addressing climate change now and in the future.

Data collection for accuracy of predictions

To be able to select for the feed efficiency trait, investigators needed to collect a lot of different phenotypes (i.e. the observable characteristics) and genotypes (i.e. genetic constitution) from cattle to be able to distinguish which animals are more efficient at converting feed into milk. Using prediction equations, they can look at the genotype from a young animal and predict early on whether that animal will be feed efficient or not. Feed efficiency and methane emissions are expensive traits to measure. It requires highly specialized equipment to accurately measure these phenotypes. With the arrival of genomics, researchers can measure those traits on a small number of animals, and then extrapolate the results on all genotyped populations, which reduces the costs.

Researchers also need a large amount of data to make accurate predictions in genomics, which is why they are collaborating with other countries for this project. The funding provided by Genome Canada, in collaboration with dairy farm organizations and other funders, gives the Canadian dairy sector the ability to measure these phenotypes, but also has the input of expertise from other countries that are also collecting data on these traits, allowing Canada to test its prediction equations for accuracy. Thus, without genomics and without the data consolidation from other countries, it would be impossible to consider feed efficiency and methane emissions in genetic selection strategies.

Real-time farm involvement in the research

 SunAlta Dairy in Ponoka, Alberta is a participating dairy in this project. The Brouwer family was in the middle of building a new free-stall barn for 450 cows and agreed to install the necessary research equipment that measures feed intake for each of the cows. By collaborating with researchers, the Brouwers are able to get a first-hand impression of the value of the research and the value of genomics. “It brings research to the farm so producers can see that the work researchers do has real-life applications and benefits. Producers get to observe these benefits first-hand”, says Dr. Filippo Miglior. Getting data from a commercial herd also allows “real-life” data to be included in the analyses. This allows investigators to get more data (since a commercial herd is often bigger than a research herd at a university research station), and gives them data from a different environment than a research herd, an environment where cows are managed in “real-time” on a dairy farm. Results from this type of research are therefore directly applicable to other commercial herds.

Future application of results for the Canadian dairy industry

Results from this research can also be applied to herd management. The plan is for selection indexes to be produced, so that farmers can select for animals that are more feed efficient and lower methane emitters. Genomic evaluation for the novel traits will be developed at the Canadian Dairy Network. This research group believes that the addition of those traits will increase the rate of genotyping of young females at the herd level for replacement decisions. The amount of time needed to collect data is significant, which explains the length of the project (10 years). However, the investment is so unique, producers will see results over the long term and for generations to come. The benefits of this research also align with the proAction environmental targets: reduce GHG emissions related to milk production, and the impact on land needed to produce milk. The usefulness of this research will become more relevant over time by breeding for dairy cows that are much more efficient than the ones we have today.


Controlling bovine infectious diseases: Canadian research teams aim to produce beneficial results for farmers


Dr. Herman Barkema, Industrial Research Chair in Infectious Diseases of Dairy Cattle (IRC-IDDC) at the University of Calgary Faculty of Veterinary Medicine has been the Senior Industrial Research Chairholder since April of 2014. The research program of the IRC-IDDC focuses on Johne’s disease and mastitis.

Industrial Research Chair – An industry partnership

Dr. Barkema ensures that every facet of this prestigious research partnership funded by the dairy industry (Alberta Milk, Dairy Farmers of Canada, Westgen Endowment Fund, CanWest DHI, Dairy Farmers of Manitoba, the BC Dairy Association, and the Canadian Dairy Network) and the Natural Sciences and Engineering Research Council (NSERC) of Canada will maximally benefit Canadian dairy producers.

Johne’s prevention and control

MSc. student Dominique Carson is investigating Johne’s disease in young stock.
PhD. student Carolyn Corbett is investigating calf-to-calf transmission of Johne’s.

A key element in the strategy to achieving eradication of Johne’s disease from the Canadian dairy herd is the adoption of prevention and control practices by dairy farmers. The results of a recent study by Dr. Barkema and his team reveal that “one-size-fits-all” recommendations for these practices will rarely be sufficient for farmers, and that more personal approaches are needed to tailor recommendations to a farmer’s specific situation.

Moreover, Dr. Barkema’s studies indicate that calf-to-calf transmission of the disease-causing pathogen Mycobacterium avium subspecies paratuberculosis (MAP) can occur, especially in calves housed in groups.

Better understanding the bacteria causing mastitis

In his work as lead of the environment research theme in the Canadian Bovine Mastitis and Milk Quality Research Network (CBMQRN), Dr. Barkema realised that although coagulase-negative staphylococci (CNS) comprise the most common group of bacteria found in udders of lactating cows in Canada, little is actually known about them. Preliminary results from Dr. Barkema’s research indicate that the total prevalence of this group of bacteria is 10%. Some CNS isolates actually inhibit growth of major Gram-positive mastitis pathogens such as Staphylococcus aureus, which might be able to be exploited commercially to reduce mastitis in dairy cows.

Research Chairs – A training ground for the next generation of scientists

The training of the next generation of researchers and extension personnel represents an additional benefit to the dairy industry from the IRC-IDDC. The graduate and summer students and postdoctoral fellows working with Dr. Barkema’s team are the boots on the ground and the gloves in the lab carrying out the numerous experiments needed to produce beneficial results for producers.

For the remainder of the 5-year IRC-IDDC, Dr. Barkema and his team will complete the projects currently underway in Johne’s disease and mastitis and will share their research findings in Canada and across the globe with dairy farmers, extension practitioners and government representatives.

Dr. Shannon L. Tracey is from Cross the “T” Consulting. Dr. Herman Barkema is professor of epidemiology of infectious diseases at the University of Calgary’s faculty of veterinary medicine, and holds a joint appointment in the Cumming School of Medicine. He is also a guest professor at Ghent University in Belgium. Barkema leads the environment research theme in the Canadian Bovine Mastitis and Milk Quality Research Network, the Alberta Johne’s Disease Initiative, the Alberta Inflammatory Bowel Disease Consortium, the Clinical Research Unit of the Cumming School of Medicine, the University of Calgary Biostatistics Centre, and the technical committee of the Canadian Voluntary Johne’s Disease Program.

New National Dairy Research Strategy Announced


Dairy Farmers of Canada (DFC) has adopted a new strategy to direct its investments in dairy production and human nutrition and health research. Four major themes have been identified:

  1. Dairy farm efficiency and sustainability
  2. Animal health and welfare
  3. Milk composition, quality and safety
  4. Milk products and components in human nutrition and health.

Each theme has targeted outcomes established to ensure that dairy research projects will address the major issues Canadian dairy farmers want solved by research. To view a copy of the strategy, visit

The strategy will serve as an important guide for future research investments by DFC.

New governance body for national research investments: The Canadian Dairy Research Council

The Canadian Dairy Research Council (CDRC) is a new committee with representation from all provinces and members of the Board of Directors of DFC. The CDRC reports to the DFC Board. It guides the overall development, implementation and delivery of research activities for dairy production, and human nutrition and health research.

The CDRC completed its first mandate in June 2016 and developed DFC’s National Dairy Research Strategy to better coordinate dairy farmers’ research investments at the national and provincial levels. The National Dairy Research Strategy was approved by DFC’s Board of Directors in June 2016 and presented to its General Council in July 2016.

Understanding Pro$ and the Lifetime Profit Curve

August 2016 marks one year since the introduction of Pro$ as one of Canada’s national genetic selection indexes. Since its inception, Pro$ has been well received by both producers and industry personnel. As a genetic selection tool, Pro$ maximizes genetic response for lifetime profitability, leading to realized daughter profit on farm. The accumulated profit a cow achieves over her lifetime depends on several contributing factors, all of which are reflected in the Pro$ index. Let’s take a closer look to better understand how Pro$ can help Canadian producers develop a herd of profitable cows.

 Lifetime Profit Curve

From the day a heifer calf is born, she starts to incur costs, the majority of which are related to feeding. With an average age at first calving near 26 months, the cost of heifer rearing is roughly $2,800 for Holsteins. Once calved and lactating, a dairy cow starts to generate her primary source of revenue – milk and its components. At the end of each lactation, no revenue is generated during the dry period but expenses continue. This concept of describing how a cow’s profit accumulates over time is its lifetime profit curve, which is shown in Figure 1 for the typical Canadian Holstein. This lifetime profit curve covers the first six years of life since this was the definition of lifetime profit used by Canadian Dairy Network (CDN) to develop Pro$.


For the typical Holstein in Canada, the complete repayment of costs incurred from birth is achieved by 40 months of age, at which time she is in her second lactation (Figure 1).

Looking closely, it can be seen that each new dry period and subsequent calving leads to higher levels of accumulated lifetime profit compared to the scenario of a cow having only one calving followed by years of consecutive production. Normally, prior to reaching six years of age, the typical cow will have had four calvings, including three dry periods, and is in progress on her fourth lactation. This underlying cycle of reproduction and production is fundamental to the dairy enterprise since heifer calves are required as future replacement animals for the milking herd. On average, about one-third of all lactating Holsteins in Canada stay in the herd to at least the age of six years. Those that do, typically end up with about 40 months of productive life in lactation along with six months for dry periods.

When producers aim to maximize herd profitability, it is important to think of the factors contributing to each cow’s lifetime profit curve, which include:

  • Age at first calving since prior to this point a heifer only incurs costs. The earlier an animal first calves, the sooner it can start paying back those rearing costs.
  • Production levels of milk, fat and protein since these are the primary sources of revenue but they are also associated with some expense, mainly feed costs.
  • Days in lactation since this is the only period during which revenue is generated.
  • Days dry, which is longer with poorer reproduction.
  • Ability to stay in the herd, which reflects a multitude of possible factors.

When examining Pro$ values, higher bulls are expected to produce more profitable daughters compared to lower Pro$ bulls. This means that the average lifetime profit curve for daughters of high Pro$ sires will be somewhat different, and higher, compared to daughters of poorer Pro$ sires. CDN recently conducted an analysis to help demonstrate how the key factors contributing to a cow’s lifetime profit curve vary between sires that are higher or lower for Pro$. To conduct this analysis only older sires could be used since their daughters would have to have been born early enough to have had the opportunity to reach six years of age. Table 1 provides various statistics describing the performance of daughters of the sires that were in either the top 10% for Pro$ of the group included in the analysis, or the bottom 10% for Pro$, relative to the daughters of the middle 10% of sires for Pro$.

screen-shot-2016-09-27-at-4-47-46-amRelative to daughters of the middle group of sires for Pro$, 7.4% more daughters of the top Pro$ sires and 6.0% fewer daughters of the bottom Pro$ sires stayed in the herd to six years of age. Evidently, longevity is a crucial component of lifetime profitability. By looking specifically at the daughters that stayed in the herd until at least six years of age, we can illustrate the profitability differences, beyond longevity, that exist between the two sire groups based on Pro$. For example, daughters of the top group for Pro$ calved younger, had more days of productive life and produced more milk, fat and protein than daughters of average Pro$ sires. On the other hand, daughters of the bottom sire group for Pro$ had an older age at first calving, fewer days in production, spent more days dry and produced significantly less than daughters of average Pro$ sires.

Since all these performance measures impact profitability, there is a clear difference in the average accumulated profit to six years of age, based on all daughters, for each of the two sire groups by Pro$. Daughters of the top sire group for Pro$ generated an extra $1,300 profit to six years than daughters of the middle sire group, while daughters of the bottom sire group generated $1,200 less profit to six years than daughters of the middle group. Bottom line is that selecting sires based on Pro$ produces daughters with higher lifetime profit curves and improved herd profitability.

Canadian dairy scientists awarded for research excellence!

In recent weeks, eight Canadian dairy scientists were recognized domestically and internationally for their contributions to dairy science in the areas of animal nutrition, food safety, animal care and welfare and animal health.

Dairy Farmers of Canada congratulates these dairy researchers for their achievements in dairy science and their contributions to innovating in Canadian dairy. All researchers are currently carrying out research on behalf of the dairy sector in projects co-financed by DFC or member organizations.

Drs. Trevor DeVries, Filippo Miglior, Kees Plaizier and Michael Steele received awards from the Canadian Society of Animal Science (CSAS) ; and, Drs. Hélène Lapierre, Xin Zhao and Micheal Steele received awards from the American Dairy Science Association (ADSA) at the Joint Annual meeting held in Salt Lake City, Utah last week. Drs. Marina von Keyserlingk and Dan Weary received the first Ruminant Well-Being Award from the World Buiatracs Association (sponsored by Boehringer Ingelheim Animal Health) in early July.

What follows is a short description of the awards received and the researchers’ current work in the Canadian dairy industry.




Dr. Filippo Miglior, chief of research and strategic development, Canadian Dairy Network – Award in Technical Innovation in Enhancing Production of Safe Affordable Food 

Dr. Filippo Miglior is a world renowned dairy cattle geneticist working in the areas of genetic evaluation and improvement. He is responsible for the management of research projects for dairy cattle genetic improvement financed by the CDN and the lead on strategic planning and research priorities for the organization. He is the lead investigator in two major dairy genetics and genomics projects in the Dairy Research Cluster and a co-investigator in two others. He is also co-leading a $10.3 million dollar project funded by partners, including CDN and Genome Canada, to increase dairy cattle feed efficiency and reduce GHG emissions from dairy cattle.



Dr. Trevor DeVries, Associate Professor, Department of Animal Biosciences, University of Guelph – Animal Industries Award, Extension and Public Service 

Dr. DeVries has made considerable contributions to the Canadian dairy industry through his research and extension work on the effects of feeding management and housing on behaviour in dairy cattle. He was a technical lead, contributor and advisor in the development of the Dairy Farmers of Canada’s proAction animal care program and has been a member of its technical committee. Recently, Trevor delivered extension information on dairy cattle care and comfort through a webinar series for Canadian dairy farmers developed by DFC and Valacta. The webinar series provides important information on the evaluation of cow comfort, comfortable surfaces and comfortable spaces based on the latest research financed by farmers in the Dairy Research Cluster. To view the recorded webinars delivered by Trevor and transfer expert Julie Baillargeon (Valacta), visit



Dr. Michael Steele, Assistant Professor, Department of agriculture, food and nutritional science, University of Alberta –  Young Scientist Award (CSAS) and the Lallemand Animal Nutrition Award for Scientific Excellence in Dairy Nutrition (ADSA) 

Dr. Michael Steele’s area of investigation is to understand how early-life nutrition and management programs can imprint the calf’s biological outcomes later in life ; uncover and evaluate feeding schemes and bioactive nutrients that display the properties necessary to improve gut health in dairy calves ; and, characterize the ruminal and intestinal adaptations during the transition to high energy diets in early lactation using feeding schemes based commonly fed commercial dairy rations.

His lab holds a keen interest in the implementation of novel feeding schemes with innovative feeding systems, such as automated calf feeders and automated milking systems.



Dr. Kees Plaizier, Professor
 and Associate Dept Head, 
Director of Ruminant Research Unit at the University of Manitoba – Award for Excellence in Nutrition and Meat Sciences 

Dr. Kees Plaizier has made important contributions to the Manitoban and Canadian dairy sector. His research include: the impact of sub-acute ruminal acidosis (SARA) on health and production of dairy cows ; environment sustainability of Dairy Farms ; dry cow management ; yeast culture products ; diagnosis of subacute ruminal acidosis and, evaluation of ruminant feeds. One of his research projects carried out for Manitoba dairy farmers provided critical information to develop best management practices to optimize the use of phosphorus in the diet of their cows.




Dr. Hélène Lapierre, Research Scientist, AAFC, Shrebrooke, Quebec – American Feed Industry Association Award 

The award is given to an individual who made an important contribution to research of dairy cattle nutrition. Dr. Lapierre is leading a major research project under the Dairy Research Cluster, the outcomes of which aim to better balance feed rations for dairy cows, and reduce protein in the ration while maintaining cow health. The recommendations that will result in balancing feed rations can potentially increase an average farms’ revenues by about $0.15 per cow per day, or almost $4,000 per year, through savings on feed costs for the cows. Reducing the proportion of protein in dairy cow rations from an average of 18.1% to a realistic 16.5%, will allow Canada to cut its nitrogen emissions by 17,000 tonnes a year and save $77.5 million annually.

Dairy Farmers of Canada is a proud investor in her research. For a summary of her work, click on the link that follows to read the article entitled, New approach to feeding cows benefits both farmers and the environment.



Dr. Xin Zhao, Professor of animal physiology, McGill University – West Agro Inc. Award 

The West Agro Inc. award was given to Dr. Zhao in recognition of his outstanding research of milk quality as affected by control of mastitis, management of milking, and practices in production of milk.

Dr. Zhao is the successful recipient of research grants provided by DFC and the Canadian Dairy Network to investigate the genetics of bovine milk cholesterol content and to investigate the interaction between pathogens and hosts in mastitis. He and his team are interested in understanding how the microbial virulence strategies affect the nature and magnitude of the host response and how the resulting immune response influences the course of infection.
