2010 journal article

Proteins involved in iron metabolism in beef cattle are affected by copper deficiency in combination with high dietary manganese, but not by copper deficiency alone

JOURNAL OF ANIMAL SCIENCE, 88(1), 275–283.

By: S. Hansen n, N. Trakooljul n, H. Liu n, J. Hicks n, M. Ashwell n & J. Spears n
