Abstract

HUSSAIN, S. O., K. I. AL-BADRY, A. S. AL-JANABI and M. K. ASOFI, 1999. Seasonal changes in serum enzymes of male goats. Bulg. J. Agric. Sci., 5: 535-538

The activity of 4 enzymes were evaluated in sera collected from 14 indigenous local bucks in Iraq over period of 12 months.
Results showed that the activity of both AST (Aspartate Amino Transferase) and ALT (Alanine Amino Transferase) were increased significantly (P<0.05) during summer, while the activity of ALP (Alkaline Phosphatase) increased significantly (P<0.05) in winter as compared to other seasons of the year. However no-significant change was noted in ACP ( Acid Phosphatase). On monthly basis significantly (P<0.05) highest activity was monthly registered during August for ALT & AST and during February for ALP. Furthermore ACP highest (non-significant) activity was in December. These results indicate that environmental changes associated with seasonal change affect various metabolic activities of bucks leading to a decrease or increase on various body functions.

Key words: seasonal, enzyme, goat
