Canada Among the First to Introduce Feed Efficiency

{Source: Lactanet press release}

The week of April 9th marked an important highlight in the history of dairy cattle improvement services in Canada as Lactanet introduced the first genetic evaluations for Feed Efficiency in the Holstein breed.

Feed is a major expense on every dairy farm and represents more than half of on-farm production expenses. Some animals are more efficient at converting feed at the bunk to milk in the tank – the primary source of income for dairy producers. Lactanet’s new Feed Efficiency evaluation focuses on selection for improved biological efficiency without affecting production levels or body size and aims to minimize stress during the transition period.

“We are very proud of the launch of new genomic evaluations for Feed Efficiency, which positions Canada among global leaders in terms of the opportunity for genetic selection to improve the production efficiency of dairy cattle”, stated Neil Petreny, Lactanet CEO, “and provide Canadian dairy farmers with additional savings for their everyday operations”. Lactanet Board Chair, Barbara Paquet, added “The Board recognizes and appreciates the significant time and effort invested by Lactanet staff, other industry personnel and the highly qualified team of research scientists involved in this initiative to reach this pivotal successful outcome”.

The launch of Feed Efficiency evaluations was made possible through a large-scale international research project that spanned from 2015 to 2020. The Efficient Dairy Genome Project was a Canadian-led collaboration involving Lactanet as the major industry funding partner and a joint research team from the University of Guelph and University of Alberta. The $10.3M initiative also received much appreciated funding from Genome Canada, Genome Alberta, Ontario Genomics, Alberta and Ontario Ministries of Agriculture and the Ontario Ministry of Colleges and Universities. Only four months after this project’s completion, Lactanet brings this latest world-leading innovation in research to dairy farms across Canada in the form of genetic evaluations for Feed Efficiency.

Initially, Feed Efficiency evaluations are available only for genotyped bulls in A.I. and females in herds enrolled on Lactanet’s milk-recording services, but access will be available to all Canadian herd owners before the end of the year. For every 5-point increase in a sire’s Feed Efficiency evaluation, the daughters are expected to reduce their total dry matter intake after peak lactation by 60 kg without impacting production levels or body weight – each and every lactation.

Are some cows genetically susceptible to Johne’s Disease?

A research project led by Nathalie Bissonnette (Agriculture and Agri-Food Canada (AAFC) -Sherbrooke) and Kapil Tahlan (Memorial University of Newfoundland) is investigating genetic markers in dairy animals that may be associated to Johne’s disease susceptibility or resistance. The project, Unraveling the genetic susceptibility to Johne’s disease, is financed by AAFC and Lactanet with in-kind contributions by Holstein Canada under the Dairy Research Cluster 3. 

For dairy farmers, this disease results in financial losses related to reduced milk production, decreased pregnancy rates, increased premature culling, and impacts overall animal welfare. Economic losses in the Canadian dairy sector resulting from Johne’s disease were recently estimated at $21.5 million to $34.1 million.[1]  

The main pathogen that causes Johne’s disease is Mycobacterium avium subspecies paratuberculosis (MAP). Management tools are currently in place to reduce the spread of Johne’s disease in Canada. For example, by implementing the Biosecurity module of proAction®, dairy farmers work with their veterinarians to mitigate the risks of introducing existing and emerging animal diseases on their farms to maintain the health of the herd. However, controlling Johne’s disease is difficult due to the disease’s unpredictable progression and the weak sensitivity of diagnostic tests. 

Previous research has shown the potential to reduce the prevalence of Johne’s disease in cattle by selecting for animals that are genetically resistant to the disease. This innovative application would be a complementary to the tools farmers can use alongside management strategies to prevent infections.  

Over a five-year period, Nathalie Bissonnette and her collaborators collected serum and fecal samples from 3,150 cows. The team used this data combined with other diagnostic tests to define a classification system and identify animals as either infected and infectious, infected and assumed resistant, or healthy. Using this unique dataset, they were able to accurately model the development of Johne’s disease over time and correctly differentiate between cows that would eventually develop Johne’s disease and those that resisted the infection and did not excrete the pathogen. The researchers are also genotyping cows using two proven genetic testing methods (i.e. single nucleotide polymorphisms (SNP) panel and genotyping-by-sequencing), and analyzing the epigenetic profile of susceptible cows.  So far, the team has identified genetic and epigenetics markers associated with the susceptibility of developing Johne’s disease.

In recent publications, the researchers confirmed the presence of genetic modifications[2],[3] and the epigenetics effects[4],[5],[6]  that are associated to Johne’s disease. 

Analysis was performed to study the markers in vitro[7],[8] and studying immune tolerance to JD using bovine primary macrophages.[9] Further research on a second population of dairy cows is ongoing and will confirm the usefulness of the genetic markers for selection of JD resistance/tolerance.

The team is also investigating the genetic diversity of MAP strains by using validated tools[10] and classifying the variants from animals across Canada that are infected with Johne’s disease at different stages. These analyses will define which factors affect the performance of diagnostic tests and explain disease progression. This ongoing work to identify MAP variants that could be more virulent will be key for the development of a successful vaccination program in the future.

Innovative research to advance genetic and genomic improvements in the Canadian dairy sector

Genetic gains in the Canadian dairy industry have been advancing at an unprecedented rate since the introduction of genomics in August 2009, when the first genomic evaluations were published in Canada.[i] In the five-year period between 2014 and 2019, the average rate of genetic gain more than doubled. It is estimated that genomic selection for novel, economically important traits could generate an additional $200 million per year in annual net benefits to the dairy sector as a result of increased genetic progress for new relevant traits. [ii]

Two research projects funded under the Dairy Research Cluster 3 (Agriculture and Agri-Food Canada and Lactanet (DairyGen Council)) will make considerable contributions to optimizing breeding strategies and maximizing genetic gains to benefit the dairy sector.

1.  Understanding the impact of cutting-edge genomic technologies on breeding strategies for optimum genetic progress in Canadian dairy cattle

Researcher Christine Baes of the University of Guelph is leading this project focused on the analysis and comparison of breeding strategies and novel tools from an economic and genetic improvement perspective to increase progress in Canadian dairy cattle breeding programs. Ultimately, the outcomes will serve to help dairy farmers make more informed decisions about using new technologies, methods and breeding strategies on their farms.

In some of the work done to date, the researchers appraised and described in detail the current breeding structure and are investigating the impact of either continuing with the current structure or incorporating new technologies and traits to optimize dairy cattle breeding programs. A list of 70 traits in use in Canada was prepared and the costs of collecting records on animals were calculated and estimates made of the genetic parameters of all measured traits. A large dataset of more than four million breeding records was used to investigate the use of reproductive technologies in Canadian herds and describe breeding practices.[iii]

Recommendations on how to best incorporate prospective new technologies and novel traits to optimize Canadian dairy cattle breeding programs will be developed, as well as considerations for adoption to help fully understand the long-term effects of altering the current breeding scheme. 

Project overview

2.  Accelerating genetic gain for novel traits in Canadian Holstein cows

Previous research has demonstrated that the accuracy of genomic evaluations for novel traits can be improved by increasing the size of the reference population in a cost-effective manner by genotyping cows that already have phenotypes for novel traits. In this new project, researcher Flavio S. Schenkel of the University of Guelph and his team are investigating ways to establish a much larger reference population of genotyped females to maximize the genetic progress for novel traits such as mastitis, metabolic diseases, fertility disorders, hoof health, feed efficiency and methane emissions. 

The researchers are aiming to genotype some 25,000 cows from commercial herds that are collecting relevant phenotypes to increase the size and diversity of the current reference population used in genomic selection. The enlarged reference population will be used to determine genetic parameters, develop or improve genomic evaluations, and deliver more accurate genomic predictions for a series of novel traits. 

A larger female reference population of genotyped cows from herds recording novel traits of interest will support and increase the accuracy of routine genomic evaluations for a portfolio of traits and accelerate genomic gains, leading to the ability to breed more disease resistant and efficient animals.

Webinar: New insights on the role of milk products in the prevention of type 2 diabetes

Eleven million Canadians are living with diabetes or prediabetes and roughly 90% of people living with diabetes have type 2 diabetes (T2D). Growing evidence suggests that dairy product consumption, including consumption of higher fat milk products, is associated with a reduced risk of developing type 2 diabetes.  

Dairy Farmers of Canada is organizing and hosting a webinar featuring speaker Anthony Hanley, Ph.D., professor in the Department of Nutritional Sciences at the University of Toronto on Wednesday, February 24, 2021 from noon to 1 p.m. (EST). He will present scientific information on the role of milk products in the prevention of type 2 diabetes, including:

  • The prevalence of type 2 diabetes (T2D), especially in Canada
  • Risk factors in the development of T2D
  • Scientific evidence on the role of milk products in the prevention of T2D
  • Potential mechanisms related to milk products in the prevention of T2D 
  • New and emerging evidence: dairy fatty acids, fermented dairy foods

Large-scale research projects investigating the role of dairy product consumption in Canadians’ health

Three research projects are currently underway that are investigating the role of dairy products on appetite (i.e. satiety), body weight, glycemic control, metabolic health and prevention of type 2 diabetes. 

  1. RESEARCH PROJECT: Effects of long-term consumption of dairy products on satiety, body weight and glycemic control

This project builds on the results of a large Dairy Research Cluster 2 study that provided evidence of the potential benefits of long-term habitual consumption of full-fat dairy to control appetite (i.e. satiety) and postprandial blood glucose. This project led by Harvey Anderson, University of Toronto, will conduct randomized controlled trials to determine the impact of the consumption of dairy products on appetite and blood glucose control (glycemia) and weight management. All three factors are related to the development of obesity and type 2 diabetes. 

Three diets will be served to a group of more than 150 men and women aged 19-45 years old for 24 weeks. The diets are: 1) a low-dairy, energy-restricted diet 2) a diet that is energy-restricted with three servings of dairy per day (regular-fat cheese, yogurt and milk); and 3) a diet of three servings per day of regular-fat dairy without energy restriction. Measurements on weight and body composition, blood pressure, blood lipids such as cholesterol and other risk factors, satiety (i.e. appetite control) and blood glucose control after meals (i.e. postprandial glycemia) will also be taken.

Scientific evidence and data published as a result of this study may support health claims related to the beneficial effects of consumption of dairy products (milk, yogurt and cheese) on curbing appetite, weight control and blood glucose.  

Project Overview

  • Principal Investigator: Harvey Anderson (University of Toronto)
  • Co-Investigator: Bohdan Luhovyy (Mount Saint Vincent University) 
  • Collaborator: John Sievenpiper (University of Toronto)

2. RESEARCH PROJECT: Role of dairy products on body weight and metabolic health in families

The objective of this project is to determine the impact of dairy products (regular fat and lower fat) on weight management in families consisting of adults and children. Led by researchers Angelo Tremblay and Vicky Drapeau, Université Laval, the team is examining the effect of dairy products on body weight and appetite control, diet quality and metabolic health in normal weight/obese adults and children using an innovative web-based approach. 

The researchers are developing a web-based program to assess the impact of integrating dairy products into the diets of families with normal weight and obese adults and children, under free-living conditions. The program will measure dairy consumption; dairy variety and diet quality; body weight and appetite control; reported energy intake; food preference and eating behaviors; and cardiometabolic risk factors (e.g. glycemic control, blood lipids). 

The evidence and data collected on dairy product consumption and weight management may help support health claims related to the beneficial effects of dairy product consumption on weight management.

3. RESEARCH PROJECT: Role of dairy products in the prevention of type 2 diabetes

Type 2 diabetes (T2D) in Canada is a significant health, economic and societal burden. Recent data from a large body of evidence has shown that dairy products, especially yogurt and cheese, may reduce the risk of developing type 2 diabetes.[i]

Researcher Sergio Burgos of McGill University and his team will conduct randomized controlled trials to determine whether eating different types of dairy products (milk, cheese and yogurt) with differing fat content can improve insulin sensitivity in overweight and obese people at high risk of developing type 2 diabetes. Evidence from randomized controlled trials will provide critical data needed to substantiate health claims regarding the benefits of consuming dairy products on type 2 diabetes prevention.

NEW RESEARCH: Providing opportunity for movement to dairy cows by redefining indoor and outdoor spaces and best management practices

Providing freedom of movement to dairy animals was cited in the top five predominant welfare concerns by respondents (43.75% were general public) to the National Farm Animal Council’s online dairy cattle survey in 2019.i As humans, we see increasing movement and exercise as good for our health. By extension, the same concepts are being applied to domesticated animals and production animals in confinement. A growing body of evidence is showing health and welfare benefits for dairy animals. But many questions remain on HOW dairy cattle can best benefit in the context of existing housing and management practices and WHY the animals behave in certain ways toward exercise or more movement.

New research led by Elsa Vasseur at McGill University and funded by the Dairy Research Cluster 3 (Agriculture and Agri-Food Canada and Dairy Farmers of Canada), will soon change our understanding of cow movement and exercise for dairy cattle housed in tie-stalls. The researcher and her collaborators are rethinking how spaces can be adapted to provide dairy cows the opportunity for more movement and exercise. They are developing, re-designing and testing indoor and outdoor spaces in a tie-stall environment to allow cows more movement while minimizing the costs to make changes and minimizing environmental impacts. Their results will serve to develop best management practices that are efficient, cost-effective and sustainable with beneficial effects for the animals, including improvements to cow comfort and health. 

The research project is timely given that revisions to the Code of Practice for the Care and Handling of Dairy Cattle (2009) and targets for better animal welfare outcomes are being considered by the industry. Up until recently, very little research has been done on the relevant and practical options to provide opportunities for movement or exercise to dairy cattle in tie-stall housing systems. Tie-stall housing makes up about 70% of the dairy cattle housing systems in use in Canada and were built because of advantages like minimizing competition for feed and lying space, and the ability to care and observe the animals individually. But for the general public, they are seen as restricting the animal’s natural or normal behaviours.

Evidence to date on cow movement and exercise suggests that the outcomes for the animals can benefit their health, behaviour and welfare.ii Some studies demonstrated that:

  • Cows are motivated to access the outdoors when provided the opportunity in both winter iii and summer ivconditions when housed in different indoor housing systems (i.e. typical freestall barn, deep bedding composted pack, etc.).
  • Tie-stall farms that provided cows with outdoor access had 20% fewer lame cows and 16% fewer cows with hock injuries at the end of the winter (the period during which cows are most restricted to the indoors) than farms providing no outdoor access.v
  • Tie-stall cows have fewer hoof lesions (10% less) if access to an outdoor yard was

The HOW – Adapting existing tie-stall systems

The researchers are examining several options to increase cow movement in tie-stall systems. They are measuring the optimal amount and length of time for movement and exercise, and at different frequencies; observing cows’ behaviour indoors and outdoors; recording the types of activities the cows engage in; and how active they are during exercise periods. They will also evaluate the effects of providing exercise on cows’ locomotion, on different outcome measures of welfare (i.e. lying time, injuries), and the impact on milk production. 

An economic and environmental assessment will identify the effects of providing indoor and outdoor exercise periods on farmers’ workloads as well as the effects on air and groundwater quality.

The WHY – Cow behaviour toward more exercise and movement

Researchers note that there may be some challenges to consider when the opportunity for more movement or exercise is provided to cows. It depends on an individual cow’s motivation to do so.

“Perhaps the biggest barrier to the efficacy of outdoor access as a means to elicit increased locomotor activity in the cow is the fact that it is largely dependent on the individual cow to engage in activities related to movement when provided this addition to her housing environment. Cows that display higher levels of locomotor activity are likely to do so in any environment in which they are placed, and visa-versa for low activity level cows. When providing free access to the outdoors, it is necessary to consider the cow’s preference to go outdoors versus her preference to stay inside.”vii

Superheroes and the science of antimicrobial use and resistance

A new and innovative illustrated comic book has been designed to explain the research process used to identify bacteria that may be resistant to antimicrobials used to treat sick dairy animals. Written in plain language, a team of “superhero” researchers and their students investigate a case of mastitis infected with bacteria that may be drug resistant. The comic book was published by Op+lait with the involvement of researchers and students of the Mastitis Network. Dairy Farmers of Canada provided financial support for the translation of the comic book from French to English.
