INFLUENCE OF LIVE YEAST SUPPLEMENTATION ON ANTIBODY RESPONSE AND SERUM BIOCHEMISTRY IN BROILERS

Inclusion of 0.1 per cent SC to the broiler diet had no significant (P < 0.05) effect on serum total proteins, albumin, cholesterol and glucose, whereas 0.2 per cent level showed significant (P < 0.05) reduction in serum cholesterol level. The result was in accordance with the findings of Stanley et al. (1993). The effective catabolism of cholesterol by SC in the intestine could be attributed to the reduction in serum cholesterol level. Supplementation of live yeast culture containing Saccharomyces cerevisiae (SC) in broiler ration enhanced immune status of birds against Ranikhet disease and infectious bursal disease. Serum cholesterol level reduced significantly (P < 0.05) with 0.2 per cent SC supplementation, while other serum parameters like total proteins, albumin and glucose remained unchanged.
