Extract

A satisfactory method of copper (Cu) supplementation, particularly in the field situation, has yet to be found (MacPherson, 1983). Work in Australia (Dewey, 1977 and Deland, Cunningham, Milne and Dewey, 1979) has shown that orally administered copper oxide wire or ‘needles’ (CuON) remained in the lining of the abomasum of sheep and calves and gradually released Cu over a long period of time. This treatment was successfully tested on hill sheep in Scotland by Whitelaw, Armstrong, Evans, Fawcett, Russel and Suttle (1980). Suttle (1979) has also recorded that calf liver Cu concentrations were raised significantly by a single 50 g oral dose in a limited term (41 day) experiment. No reports have appeared of the usefulness of this treatment under field conditions for the bovine in this country. Three trials are described which examined the effectiveness of small oral doses of CuON on the Cu status of beef suckling calves, dairy heifers and beef suckler cows.
