Two complete diets (I) without yeast culture (control) and (2) lyophilized yeast culture at 0.1 per cent level were formulated and processed into mash using sorghum straw as sole source of roughage. These two diets were fed to 12 Deoni bull calves of 6 each. (5–6 m old) in a experiment to assess the effect of yeast culture on growth and nutrient utilization. The DMI was 5.3 per cent higher on the diet containing yeast culture. Digestibilities of all the nutrients and DCP and TDN contents were signifincantly (P<0.05) higher on diet containing yeast culture. The ADG was significantly (P<0.05) higher and feed intake/kg gain was significantly (P<0.05) lower on the diet containing yeast culture. These results indicate that incorporation of yeast culture at 0.1 per cent level in the diet of growing Deoni bull calves improved the animal performance in terms of higher ADG (P<0.05) and decreased feed/kg gain.
