THE EFFECT OF BIOTIN ON BLOOD METABOLITES IN F1 WAGYU-BLACK ANGUS STEERS

摘要

Biotin belongs to the water-soluble B vitamin group. It is an essential co-enzyme for the activation of a range of carboxylase enzymes. These enzymes play vital roles in cellular fatty acid and glucose metabolism. Biotin deficiency has been associatedwith feeding grain-based diets to cattle by reducing rumen pH and compromising ruminal biotin synthesis (Fitzgerald et al. 2000). A feedlot experiment was conducted over 400 days to determine the effects of biotin supplementation at 3 levels (0, 10, 20mg/hd/d) on the growth, health and meat quality of F1 Wagyu-Black Angus steers. The effect of biotin supplementation on some blood metabolites was investigated.
