Fifty male buffalo calves of 9 month old were randomly divided into five groups, 10 animals in each group, using Randomized Complete Block Design. Five isonitogenous (16% crude protein) and isocaloric (2.6 Mcal/kg) diets were formulated. The control diet had 0% corn steep liquor and in 20, 40, 60 and 80% diets, urea on nitrogen equivalent was replaced by corn steep liquor, respectively.Animals were given weighed amount of feed twice daily at ad libitum. The daily feed offered and refusals were recorded to calculate dry matter intake. The sample of feed offered and refusal were used to determine dry matter, crude protein, neutral detergent fiber and acid detergent fiber. Animals fed 40% corn steep liquor diets ate highest dry matter (3.33kg daily)and was the lowest (3.16 daily) by those fed 40% corn steep liquor diets. The neutral detergent fiber and acid detergent fiber digestibility was higherin animals fed diets containing corn steep liquor than those fed diet containing 0% level. However, dry matter and crude protein digestibility remained unaltered across all diets. Calves fed 40% corn steep liquor diets gained more weight (757 g/day) than those fed 80% (637 g/day). Pre slaughter weight of animals fed 40% corn steep liquor diet was the highest (141.5 kg) and was the lowest (130 kg) in those fed 80% corn steep liquor diet. Warm carcass weight was higher in animals fed 40% (65.8 kg) diet followed by those fed 60%, 80%, 20% and control diets. Primal cuts, ash, Na, K and Ca remained unchanged across all diets. The red blood cell count, white blood cells, packed cell volume and hemoglobin values were also same across all diets. In conclusion, animals fed CSL40 diet gained more weight and were cost-effective when compared to those fed control, 20%, 60% and 80% diets. Key words: Buffalo Calves, Corn Steep Liquor, Intake, Digestibility, Growth Performance. *Corresponding author: Tel: +923007601848 E-mail address: mshahbazqamar@gmail.com
