Optimizing health and production of cows milked in robotic systems

New research started in 2018 under the Dairy Research Cluster 3 is investigating ways to maximize the efficiency of robotic milking systems and optimize cow health within those systems. The project, led by Dr. Trevor DeVries of the University of Guelph, is very timely – about 11% of farms enrolled in a milk recording program in Canada use robots and the adoption of this technology continues to increase.

The scope of the new research is impressive. This is the first study of its kind to investigate robotic milking technologies on farms across all provinces, using data collected in collaboration with Lactanet. The research team includes top Canadian experts in the fields of dairy cattle health, farm management and nutrition, spanning across Canada: Drs. Greg Penner and Tim Mutsvangwa (University of Saskatchewan), Drs. Karin Orsel and Ed Pajor (University of Calgary), Dr. Todd Duffield (University of Guelph) and Richard Cantin, Débora Santschi and René Lacroix (Lactanet).

The research team will be identifying cow and herd-level factors that influence milk production, cow health and the efficiency of robot use in a large-scale sample of dairy farms. The information will be used to identify best management practices to help farmers using robotic systems produce milk more efficiently and maintain excellent dairy cow health, with a specific focus on health in early lactation and feeding practices in robotic barns, based on barn design and layout, for all stages of lactation.

“Considering the number of farms using robotic technology and the potential for growth, there are still gaps in our knowledge on the best strategies farmers can use to address some of the challenges we identified in the Dairy Research Cluster 2 research. This new research will build on those results,” said Dr. DeVries.

In the Dairy Research Cluster 2 project on automated milking systems, the researchers demonstrated that lower milk production and issues with cow health, especially in early lactation, impacted the profitability of adopting robotic systems. Lameness, for example, was one of the primary factors identified with an overall negative impact on milk yield per cow and per robot. Clinically lame cows (gait score of 3 out of 5 or greater) were 2 times more likely to be fetched and produced 1.6 kg of milk less per day than healthy cows and milked 0.3 fewer times per day. Severely lame cows (gait score of 4 out of 5 or greater) were most likely to turn into chronic fetch cows.

Over a 12-month period, this group of researchers will be collecting data on housing, feeding and management by farm and by robotic system, and extract milk recording data for each herd. The data will be analyzed to assess cow and herd level impacts on milk production, health and robot use.

“The extent of the dataset collected by farm and by region will allow us to assess robotic system performance. We will then be able to make some associations or differentiations and develop benchmarks dairy farmers can use if they are already milking with robots or are thinking about installing the technology on their farm. We look forward to developing some very practical independent information for Canadian dairy farmers that is science-based and supports their application of the technology in the most efficient way,” concluded DeVries.

Dairy product consumption is associated with lower risk of mortality and cardiovascular events: Findings from the landmark PURE study

shutterstock_55879525Researchers at the Population Health Research Institute (Hamilton, Ontario), led by Dr. Andrew Mente, are part of a landmark 21-country multinational cohort study (the PURE study) of individuals aged 35-70 years old. They tracked dietary intakes and consumption of milk, yogurt, and cheese of 138,484 individuals over time. They also tracked mortality and total major cardiovascular events (i.e. major CVD, stroke, myocardial infarction) to assess any associations between total dairy and specific dairy product consumption with mortality and CVD events. In a scientific paper published in November 2018 in the prestigious journal, The Lancet, the team of researchers found dairy consumption, especially of regular fat dairy, was associated with a lower risk of mortality and major cardiovascular disease events in a diverse multinational population.

Additional research by Dr. Mente associated with the PURE study, and funded in part by Dairy Farmers of Canada, aims to:

  1. Assess the association of dairy product intake, dairy fat content, types of dairy foods, and dietary saturated fatty acids, with blood lipid levels; and,
  2. Investigate the association of dairy product intake, dairy fat content, types of dairy foods, and dietary saturated fatty acids, with obesity (central and overall), diabetes, blood pressure, and hypertension.

Watch Dr. Mente’s presentation on the PURE study delivered at the International Dairy Federation conference on The Role of Ruminants in Sustainable Diets of June 21, 2019 (starts at 05:00): Recent findings from the PURE study:  the case of saturated fat, dairy, meat.

Update on the Industrial Research Chair in the Sustainable Life of Dairy Cattle

Improving the comfort and longevity of dairy cows can improve dairy farm sustainability and profitability. This is the premise of the Industrial Research Chair in the Sustainable Life of Dairy Cattle, launched in 2016 and led by Dr. Elsa Vasseur of McGill University. Preliminary results of multiple studies presented in May 2019 by the scientist and her team show promise for new and innovative approaches to cow comfort and longevity.

Preliminary results to date:

  • Existing tie-stalls at the Macdonald Campus barn were adjusted to deepen bedding using a bedding guard, increase the volume of straw used in bedding to 3’’ and increase the stall length, which resulted in increased lying times, less hock injuries, thus improving overall cow comfort. The study team cautions, however, that individual barn conditions like ventilation and humidity must be considered and management adjusted for a successful deep-bedded stall system.
  • Increasing the tie-stall tie length from 1 metre to 1.4 metres allowed for more opportunity for cow movement within a stall. The study team noted that the change in tie length should be done gradually by choosing which cows benefit most from it and assess how the animal gets used to the change in tie length.
  • Cows are using a variety of resting postures in wider stalls resulting in better cow rest, confirming that current recommendations for stall width must be met at a minimum.
  • Housing dairy cows in loose pens during the eight-week dry period was beneficial for rest and locomotor recovery. These benefits can be attributed to a combination of factors: fewer obstacles in the environment (by eliminating the stall itself), a larger rest area, and a more comfortable lying area. This study established references to broaden the implementation of dry-off pens.
  • Measuring the impact of early cases of mastitis and lameness on the productive life of a cow show that a healthy beginning ensures a higher profit lactation. Identifying at risk stages of production and at-risk cows enables farmers to select the best candidates for a next lactation.
  • Key data is being collected on cost/profit variables farmers can use in their decision-making to develop an interactive herd management tool that will help improve the profitability and longevity of the herd.

Watch the video testimonial from the Roy family of Coaticook, Quebec, as they explain how they used some of the research recommendations to make changes on their farm to improve their cows’ comfort.
