Two adult female goats presented with symmetrical alopecia, rough hair coats, weight loss, and generalized unthriftiness. In light of the history and clinical signs, we suspected a mineral deficiency or endocrine imbalance. These animals were being fed a diet of alfalfa, a legume high in calcium, which can block zinc uptake. Serum zinc levels were low, and skin biopsies supported the diagnosis of zinc deficiency. Therefore, these findings suggest that the main factor blocking zinc absorption was increased dietary calcium.
