Abstract
Cupric oxide needles (CuON) provided as oral doses, 20 g for cows and 4 g for calves, at the start of an 85-d grazing trial had no influence (P > 0.05) upon body weight. At day 85 the concentration of Cu in liver was higher (P < 0.01), while that in blood serum was not influenced (P > 0.05) in cows or calves dosed with CuON. Doses of CuON had no effect (P > 0.05) upon the concentration of Zn in blood serum, nor did they (P > 0.05) modify the accumulation of Fe in liver tissue, of cows or calves. Key words: Cattle, cows, calves, grazing, copper, cupric oxide needles
