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 provided.vi

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.

NEW RESEARCH: Surveillance of antimicrobial use and resistance to improve stewardship practices and animal health on dairy farms

The increase in antimicrobial resistance in dairy cattle could have adverse effects on animal health and welfare, impacting the profitability of dairy farms. About 48% of antibiotics prescribed to a dairy farm are to treat mastitis infections in cattle.[i] While most mastitis pathogens are low in antimicrobial resistance, choosing and using other antimicrobials to treat dairy cattle health can result in the transfer of antimicrobial resistance in bacteria other than mastitis pathogens.

Researchers are developing a surveillance program to measure antimicrobial use (AMU) and antimicrobial resistance (AMR) on Canadian dairy farms, as well as the effectiveness of antimicrobial stewardship protocols and programs. Led by researchers Javier Sanchez and Luke Heider (University of Prince Edward Island) with collaborators from across Canada, the team is collecting data and information to help support farmers’ efforts in applying effective antimicrobial stewardship practices.

The pan-Canadian team has developed a platform to collect data and monitor AMU and AMR. The Canadian Dairy Network of Antimicrobial Stewardship and Resistance (CaDNetASR) is a first for the dairy sector and designed to conform with the Federal Action Plan on Antimicrobial Resistance and Use in Canada, and the Food Safety and Biosecurity modules of proAction®. Data is being collected on about 150 dairy farms in British Columbia, Alberta, Ontario, Quebec, Nova Scotia and New Brunswick on a yearly basis.

“The network has been very active since the funding of the project and even under the Covid-19 situation, we are completing the second year of data collection. We’re focused on two major activities in the network. The first is the harmonization of veterinary clinic dispensing records to quantify the use of the antimicrobials in each of the participating farms. This is being conducted with the active participation of veterinary clinics representing the study farms. The second activity is the development of intervention strategies to assess their impact on mastitis, cow health and animal welfare. In addition, we are finalizing the data management system that will allow the generation of reports to send back to producers with their antimicrobial usage and antimicrobial resistance profiles compared to the other study farms.”

Javier Sanchez, co-lead of the project.

To provide antimicrobial use data estimates, treatment records logged as part of the Food Safety and Biosecurity modules of proAction®, and the retrieval of receptacles placed on farms for the deposit of empty drug bottles and containers are being used. To measure antimicrobial resistance on dairy farms, fecal, environmental and bulk tank milk samples are being taken and analyzed. The information will serve as a base for the development and testing of evidence-based and effective tools for farmers and their veterinarians (i.e. standard operating protocols or SOPs). 

“CaDNetASR has also developed a repository of bacterial isolates that, along with the other data being generated, will allow for future analysis and studies on AMU and AMR on Canadian dairy farms.”

Luke Heider, co-lead of the project.

The project outcomes will support farmers in continuing to use antimicrobials responsibly, apply efficient antimicrobial stewardship practices and assure the continued health and welfare of dairy animals and the safety of food for consumers. 

SEVEN facts about antibiotic use and antimicrobial resistance in the Canadian dairy sector

1.   Under proAction®, milk is produced according to strict provincial and federal regulations and high standards regarding antibiotic use to treat sick animals. proAction milk quality and food safety standards are among the highest in the world. 

2.   Dairy farmers use antibiotics to treat sick animals if necessary and as directed on the prescribed medication label and directives given by the herd’s veterinarian.

3.   Canadian milk is free of antibiotics. Cows treated with antibiotics for a medical reason are clearly identified, and the milk is discarded. The milk does not re-enter the system until the mandatory withdrawal time has been met to ensure the medication is out of the animal’s system.

4.   All milk is tested for antibiotic residues at the time it is picked up from a farm and again when it reaches the processing plant to guarantee it is antibiotic-free.

5.   Antibiotic resistance happens when bacteria change and become resistant to the antibiotics used to treat the infections they cause. (ii)

6.   Antimicrobial resistance development in major pathogenic bacteria found in dairy cows does not yet appear to be a major problem in North America (iii). Most antibiotic treatments are to treat mastitis, and the levels of antimicrobial resistance remain low in mastitis pathogens (iv-vi). But, the pressures to select and use antimicrobials to treat animals more rapidly for better health can result in the emergence and transfer of bacteria that are resistant (iii). 

7.   Disease prevention is key in a strategy to reduce antimicrobial use and resistance!

Resources for dairy farmers: Fact sheets to improve dry-off procedures

  1. FACT SHEET: Recommended protocol for the administration of an internal teat sealant for dairy cows

A collaborative project between the Mastitis Network and Dairy Farmers of Canada, this new fact sheet available in English, French and Spanish contains best practices and visual step-by-step procedures for the administration of an internal teat sealant at dry-off. A growing number of farms are using teat sealants as a preventative measure for better udder health, as part of a broader strategy to reduce antimicrobial use on dairy farms. 

To download a copy of the fact sheet available at no cost, visit: MastitisNetwork.org.

A series of additional fact sheets containing best practices for testing, treatment and prevention of mastitis on dairy farms is available on the Mastitis Network’s website at MastitisNetwork.org.

2. FACT SHEET:  Drying off cull dairy cattle at high production and in emergency situations

This fact sheet published in August 2020 in English, French and Spanish contains dry-off procedures for lactating dairy cows in accordance with Canada’s high standards for animal welfare while adhering to the federal transport regulations (2020). New transport regulations require that lactating animals should not be transported unless they are milked at intervals sufficient to prevent udder engorgement.[i]

A team of experts from the Mastitis Network, led by Dr. Trevor DeVries (University of Guelph), developed the fact sheet’s recommendations on the basis of recent scientific evidence for best practices for animal health and welfare prior to transporting an animal leaving the farm. The best practices address high and low producing dairy cows, as well as the steps to take when the animal’s departure date from the farm is known or unknown, such as in an emergency situation.

New expert consensus on healthy beverages in early childhood

Recommendations on healthy beverage consumption in early childhood (birth to age 5) were recently made available by an expert panel from leading health and nutrition organizations which included: The Academy of Nutrition and Dietetics, the American Academy of Pediatric Dentistry, the American Academy of Pediatrics and the American Heart Association. 

In early childhood, beverages comprise a large portion of the diet and make a significant contribution to nutrient intakes.

Milk is an important source of several nutrients that young children need for proper growth and development such as: protein, calcium, vitamins A, D, and B12, potassium, phosphorus, riboflavin, and niacin. Whole milk may be introduced, starting at 12 months. 

While fortified plant-based beverages have added nutrients, such as calcium and vitamin D, the amounts are inconsistent and vary by type and brand. Evidence suggests nutrients from plant-based beverages are not as bioavailable compared to milk.

From ages 2 to 5, milk and water are considered as the “go to beverages.”

New pediatric position paper: Cow’s milk important for children’s optimal growth and development

The North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition latest Position Paper on plant-based beverages emphasizes that plant-based beverages do not provide a similar nutritional profile as cow’s milk and thus may be harmful to children’s nutritional status, growth and development.

The position paper highlights the important role that cow’s milk plays in young children’s diets in providing key nutrients to promote optimal growth and development. 

The protein that cow’s milk provides to young children is especially important. Both protein quantity and quality are important to consider. For example, a 250 mL serving of almond or rice beverage provides only 2% or 8% of the protein found in cow’s milk, respectively.  The lower quality protein in plant-based beverages further reduces their nutritional value compared to cow’s milk. 

Fortification of plant-based beverages with calcium and vitamins also varies as does the bioavailability of the added nutrients. 

Education is needed to clarify that plant-based beverages are not nutritionally equivalent to cow’s milk.

Dairy product consumption is associated with lower risk of mortality, cardiovascular events and Type 2 diabetes

shutterstock_722701990

In 2019, a team of researchers found dairy consumption, especially of whole fat dairy, was associated with a lower risk of mortality and major cardiovascular disease events in a diverse multinational population. The study called PURE is a landmark 21-country multinational cohort study of individuals aged 35-70 years old. It tracked dietary intakes including consumption of milk, yogurt, and cheese of 138,484 individuals over time as well as mortality and total major cardiovascular events (i.e. major CVD, stroke, myocardial infarction). The researchers assessed any associations between total dairy and specific dairy product consumption with mortality and CVD events.

New data from the PURE study and published in a scientific journal in May 2020 assessing dairy intake (total, whole fat and low fat) with a prevalence of Metabolic Syndrome (MetS) and the incidence of hypertension and type 2 diabetes also found:

  • Higher intake (at least two servings/day compared with zero intake) of total dairy was associated with a lower prevalence of MetS;
  • Higher intake of whole fat dairy consumed alone or consumed jointly with low fat dairy was associated with a lower MetS prevalence. Low fat dairy consumed alone was not associated with MetS;
  • Higher intake of total dairy was associated with a lower incidence of hypertension.
  • With regards to diabetes, higher intake of both whole fat and low fat dairy was associated with a reduced risk.

The PURE study is mainly funded by the Population Health Research Institute (PHRI) as well as several government agencies and pharmaceutical companies. This specific study, Dairy consumption and cardiovascular disease in diverse populations (2018-2019), led by Andrew Mente, McMaster University, was also co-funded by Dairy Farmers of Canada (via the Nutrition Research Funding Program) and the National Dairy Council (US).
