Abstract
Twelve local adult male goats were randomly allotted to two equal groups and were kept on ad libitum wheat straw, supplemented with either conventional concentrate mixture (Control) or concentrate mixture containing walnut cake (10% w/w) (Treatment). Positive balances of calcium and phosphorus were observed in both groups without any significant (P>0.05) difference. Blood biochemical parameters were within normal reference limits without any significant difference between dietary treatments, except a significant linear increase (P<0.05) in aspartate aminotransferase activity in the treatment group, as the feeding trial progressed. It may be concluded that incorporation of up to 10% of walnut cake in the concentrate mixture does not lead to any negative effect on the calcium and phosphorus balance in adult male goats, however, it may cause hepatotoxic effects, as indicated by the elevated aspartate aminotransferase levels and therefore caution needs to be exercised in incorporating walnut cake in ruminant rations.
