High-yield dairy cows producing 12,000+ liters per year experience health and welfare challenges from the metabolic demands of extreme milk production.
High-yield dairy cows experience chronic metabolic stress from the physiological demands of extreme milk production. Negative energy balance after calving causes ketosis and fatty liver disease. Lameness rates in high-production herds can exceed 25%. Mastitis from high milk pressure causes painful udder inflammation. Reproductive efficiency decreases as the cow body prioritizes milk production over reproduction. These health problems represent ongoing suffering in individual animals whose genetics push milk production beyond what their bodies can healthfully sustain.
