6.11 NSERC IRC_ANNE LAARMAN (JUL 2020)
Dr. Anne Laarman was recently appointed as the NSERC Industrial Research Chair for dairy nutrition.
Management and Feeding of Heifer Calves, Part 1
Heifer calves represent the future of dairy farms and their care in early life can have short- and long-term effects on growth, health and performance in their first lactation. There are some major decisions that producers make for calf management in early life, including colostrum feeding, housing, pre-weaning feeding programs, weaning and disbudding/dehorning. In order to better understand where the industry strengths and opportunities lie, it is important to determine what calf management practices are being used on dairy farms in Canada. This helps to drive research in the area of calf management and develop best management practices on farm.

The first research summary for this month is an article out of the National Dairy Study conducted in 2015. This summary provides an overview of calf management practices for early life that are being used on Canadian dairy farms and how these practices might affect calf performance. In the second research summary, DRECA is proud to introduce Dr. Anne Laarman, the newly appointed NSERC Industrial Research Chair for dairy nutrition. This summary provides some background on Dr. Laarman and his research plan for his 5 year appointment.

Results from the National Dairy Study were used to determine what calf management practices are being used on farm.
While a lot of research has focused on the pre-weaning care of heifer calves, particularly liquid feeding programs, solid feed and weaning strategies have received less attention. However, the transition from liquid to solid feed can be stressful to calves and their digestive tracts. DRECA interviewed Dr. Anne Laarman to discuss solid feed programs and strategies to provide calves with a smooth weaning transition.
Colostrum management is vitally important for calf health in early life. The Ontario Ministry of Agriculture, Food and Rural Affairs has produced a fact sheet for recommended management practices for colostrum, written by Brian Lang.
An “Ask an Expert” question was submitted on the ‘gold standard’ for disbudding pain management practices and the benefits of implementing these recommended practices. Dr. Charlotte Winder, a veterinarian at the University of Guelph responded to this question and outlined why pain control is necessary, what the gold standard procedure is and the benefits of following recommended practices for both the calf and the farmer. Check out her answer here.
Use of caustic paste for disbudding is becoming more common. In this research paper, Dr. Winder evaluates the pain response from caustic paste and the efficacy of anesthetic treatments.
