Body condition scoring provides a systematic tool for monitoring dairy cow nutritional status and welfare, helping prevent both obesity and dangerous thinness.
Body condition reflects the cumulative outcome of feeding, health, and management decisions over months. Cows that enter calving over-conditioned mobilize fat rapidly after birth, risking ketosis (which causes weakness, anorexia, and liver damage) and displaced abomasum. Under-conditioned cows suffer from reduced energy reserves, poor immune response, and reproductive failure. Systematic BCS monitoring by trained staff allows early intervention before clinical disease develops. The tool connects directly to welfare because it makes visible what might otherwise be overlooked — a cow that has been quietly losing condition for weeks before becoming visibly ill.
