Susceptibility of North Ronaldsay sheep to copper from cupric oxide needles. 1985

D P Britt, and G H Yeoman

Three housed North Ronaldsay sheep were treated with copper in the form of cupric oxide "needles", two at the manufacturer's recommended dosage rate and the third at twice this level. Sheep of this breed are especially sensitive to high dietary intake of copper. Pre- and post-dosing blood samples were monitored for changes in packed cell volume and changes in content of plasma copper, bilirubin, AST and SDH. Weight changes were also recorded. The animal dosed at twice the recommended level died on day 19 post-dosing of acute copper poisoning. The two dosed at the standard rate remained healthy and put on weight steadily throughout the six months following treatment. Two Welsh Mountain sheep dosed at the standard rate and maintained and examined in the same way likewise showed no signs of copper toxicity.

UI	MeSH Term	Description	Entries
D007064	L-Iditol 2-Dehydrogenase	An alcohol oxidoreductase which catalyzes the oxidation of L-iditol to L-sorbose in the presence of NAD. It also acts on D-glucitol to form D-fructose. It also acts on other closely related sugar alcohols to form the corresponding sugar.

D004198	Disease Susceptibility	A constitution or condition of the body which makes the tissues react in special ways to certain extrinsic stimuli and thus tends to make the individual more than usually susceptible to certain diseases.

D005260	Female		Females
D006400	Hematocrit	The volume of packed RED BLOOD CELLS in a blood specimen. The volume is measured by centrifugation in a tube with graduated markings, or with automated blood cell counters. It is an indicator of erythrocyte status in disease. For example, ANEMIA shows a low value; POLYCYTHEMIA, a high value.
