Copper deficiency is a widespread but often undiagnosed welfare problem in cattle that causes poor growth, anemia, immune dysfunction, and reproductive failure. Systematic prevention dramatically improves herd health.
Copper deficiency represents a welfare problem that often goes undetected because subclinical signs - poor growth, reduced immunity, reproductive failure - are easily attributed to other causes or accepted as normal herd variation. The welfare impact is real: cattle with inadequate copper have compromised immune function making them more susceptible to infectious disease, poor coat condition, anemia causing fatigue, and reproductive failure reducing fertility. Swayback in calves is particularly distressing - affected calves cannot walk or nurse normally and have a poor prognosis. Systematic copper monitoring through soil testing, herbage analysis, and regular blood or liver sampling allows targeted supplementation that dramatically improves herd welfare and performance. The challenge is distinguishing copper deficiency from molybdenum-induced antagonism, which requires different management approaches.
