Responses to some common methods of copper and selenium supplementation in Manawatu sand country herds


, : Responses to some common methods of copper and selenium supplementation in Manawatu sand country herds. Proceedings of the 5th Seminar of the Dairy Cattle Society of the New Zealand Veterinary Association held at Auckland, New Zealand, 22-24 June 1988: 127-152

The selenium and copper status of 3 sand country dairy farms in Manawatu, New Zealand, was estimated by analyzing animal tissues and plant materials regularly for 12 months. Serum and liver were collected for Cu estimation and blood was taken for estimation of glutathione peroxidase. Grass samples were collected for estimation of Cu, sulphur, iron and molybdenum. Results indicate that the farms were deficient in Se and Cu.
