COPPER CONTENT IN SHEEP MILK.

The Copper Content of Milk

The presence of copper in cow’s milk has been reported by several investigators (l-5). The most extensive investigation was that of Supplee and Bellis (2) who determined the copper content of freshly drawn milk of a large number of cows fed on different rations. They found that the copper content per liter varied from 0.2 to 0.8 mg., with no apparent correlation between copper content and ratio...

Effect of faunation on ruminal solubility and liver content of copper in sheep fed low or high copper diets.

Naturally fauna-free crossbred rams approximately 5 mo old, 49.3 +/- 1.88 kg live weight, were allotted to four groups. Two groups remained fauna-free, whereas the other two groups were faunated. A diet based on corn silage-soybean meal containing either a low or a high Cu concentration (7 or 15 micrograms/g dry matter) was fed ad libitum to the two groups for 197 d. The rams were killed at the...

Chronic Copper Poisoning in Sheep: Liver Injury

Pathogenesis of liver injury in chronic copper poisoning of sheep was investigated using two experiments. Test sheep were dosed orally with a 0.2 % solution of CuSO4.5H2O at the rate of 10 ml/Kg body weight on five days of the week, until first day of the haemolytic crisis (HC). Liver samples were taken during the prehaemolytic period and on the first or second day of the HC, liver changes were...
