The effects of copper supplementation on stock health and production

Abstract

Extract

Hypocuprosis in dairy cattle in Northland was first recorded by Smith (1972). Smith and Coup (1973) considered that a relationship existed between the low copper status of stock, the imbalance of copper and molybdenum in pasture, the incidence of post-parturient haemoglobinuria (P.P.H.) (Martinovich and Woodhouse, 1971), and the anaemic state of affected herds. Brief mention of benefits accruing from copper supplementation was made by Smith (1973).
