Copper, zinc and molybdenum in goat liver.

The concentrations of copper, zinc and molybdenum were measured in the liver of goats from western and south-eastern Norway. The mean copper concentrations in the liver of goats from these two districts were 23±19 µg Cu/g and 59±31 µg Cu/g wet weight, respectively. As for zinc and molybdenum, no difference was found between the two groups of animals. No correlations were detected between copper and zinc, zinc and molybdenum, or copper and molybdenum. The copper levels in Norwegian goat liver are considerably lower than in sheep liver, and the ranges are significantly more narrow. The concentrations of molybdenum in goat liver are at the same levels as in sheep and swine, while the levels of zinc are somewhat lower.
