Incidence of hypocupraemia in cattle in the east Midlands

Serum copper values were determined on composite samples from cattle herds in the Midland counties of Derbyshire, Leicestershire and Nottinghamshire. Sampling took place over a period of 17 months and the results indicate that hypocupraemia existed in many herds. The lowest values were found in heifer group samples and the lowest of these was found in Derbyshire. The geographical and management factors which may affect the copper status of herds in this area are discussed.
