The quality and appropriateness of cattle feed affects welfare directly through nutritional health, rumen function and the prevention of metabolic diseases that cause significant suffering.
Cattle nutrition is both a production issue and a welfare issue with direct connections between feed quality and disease states that cause suffering. Sub-acute rumen acidosis from high-starch diets causes pain through rumen pH disruption, and affected cattle show reduced welfare indicators. Ketosis in transition dairy cows causes a prolonged debilitating illness that is substantially preventable through transition nutrition management. Mycotoxin contamination of poorly stored feed creates immune and neurological welfare problems. Good nutritional management requires understanding the specific metabolic needs of cattle at different life stages and production levels — knowledge that translates directly into welfare improvement when applied consistently.
