An investigation into the content of trace elements in cow livers.

Abstract

Copper, zinc, manganese, molybdenum and cobalt were estimated in the livers of 62 cows. Half of the animals had been treated for 5 weeks with Vevoron, an antithyroid preparation containing methylthiouracil, for fattening. On a low-protein diet the Vevoron had increased slaughter weight and the weight of the livers.

The contents in pg. per g. dry liver of Cu, Zn, Mn, Mo and Co in control animals were 116, 144, 10-9, 4-98 and 0-37. In experimental animals they were 120, 125, 8-4, 4-24 and 0-34. Zn, Mn and Mo were significantly decreased by Vevoron. Cu and Co were not significantly affected.

In animals with infections except fascioliosis of the liver, and those with fascioliosis of the liver only, the only difference in content of trace elements in the livers was in Cu, which was higher in the healthy animals.-T. D. Bell. (Abstract retrieved from CAB Abstracts by CABI’s permission)
