Copper deficiency in calves in northcentral Manitoba.

Abstract

Four seven month old Simmental calves were examined because of unthriftiness, a persistent cough, stiffness and lameness. The calves had gastrointestinal and pulmonary parasitism. Analysis of the blood copper levels of these calves and of cows and calves on the farm indicated a generalized deficiency. Only the calves affected with parasitism showed signs of clinical copper deficiency.
