Copper, Zinc and Molybdenum in Goat Liver

Kobber, sink og molybden i geitelever

Abstract

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.

Sammendrag

Kobber, sink og molybden ble besternt i lever fra 134 geiter, 81 fra Vestlandet (Nordfjordeid) og 53 fra Østlandet (Ås). Prøvene ble innsamlet i forbindelse med slakting. Dyrene fra Ås hadde det høyeste kobberinnhold med gjennomsnittsverdi på 59 µg Cu/g lever våtvekt, mens dyrene fra Vestlandet viste et gjennomsnitt på 23 µg Cu/g.

Det ble ikke funnet forskjeller i nivåene av sink og molybden mellom de to distriktene, og det var ingen innbyrdes korrelasjon mellom de tre elementene.

Nivåene av kobber hos norske geiter ble funnet å være betydelig lavere enn hos sau, og spredningen var også mindre. Konsentrasjonen av molybden var imidlertid av samme størrelsesorden som hos sau og gris, mens innholdet av sink var noe lavere enn hos disse dyreartene.
