The biological selenium status of livestock in Britain as indicated by sheep erythrocyte glutathione peroxidase activity. 1979

P H Anderson, and S Berrett, and D S Patterson

The reliability of erythrocyte glutathione peroxidase activity as an indicator of selenium status in livestock is discussed. Based on this measurement, a survey is described of the biological selenium status of sheep on each of 329 farms in Britain. Results showed that 47 per cent of these farms were probably unable to provide grazing livestock with sufficient selenium to maintain blood levels greater than 0.075 microgram per ml. Increased selenium deficiency from the increasing use of home grown feeds as a major constituent of livestock rations may be causally related to the increase of white muscle disease and other selenium responsive diseases in Britain.

D000829	Animals, Domestic	Animals which have become adapted through breeding in captivity to a life intimately associated with humans. They include animals domesticated by humans to live and breed in a tame condition on farms or ranches for economic reasons, including LIVESTOCK (specifically CATTLE; SHEEP; HORSES; etc.), POULTRY; and those raised or kept for pleasure and companionship, e.g., PETS; or specifically DOGS; CATS; etc.	Farm Animals,Domestic Animals,Domesticated Animals,Animal, Domestic,Animal, Domesticated,Animal, Farm,Animals, Domesticated,Animals, Farm,Domestic Animal,Domesticated Animal,Farm Animal
