CAHSS Dairy Network

Canada’s dairy industry is synonymous with health. The milk flowing from our 12,529 dairy farms remains a staple in the diet of many, and a key component of our national food supply. CAHSS’s Dairy Network is committed to industry vitality. Bringing together participants from industry, government and veterinary associations, this group is a platform where members can discuss disease challenges and organize surveillance activities to maintain the health of Canada’s dairy herds.
