The current study was undertaken to evaluate the growth performance and blood biochemical analysis of buffalo calves kept under feedlot by feeding two dietary regimes. Twenty male calves of 9-12 months of age, 115±10 kg body weight were divided into two groups with initial group weight of 1165±05 kg. They were fed two diets as Ration-I (3200 Kcal and 16%) and Ration-II as (3400 Kcal and 18%). Regarding roughage proportion maize fodder and wheat straw were fed. Daily feeding allowance was offered as 3% body weight. Water was available 24 hr. Deworming was performed. Trial was lasted for 120 days. At end of the trial blood is collected and tested for different biochemical indices. Data collected on different parameters were analyzed by using t-test on Statistix software. Significant Overall weight gain and average daily weight gain (P<0.05) was observed as 78±2.54, 94±1.15 kg and 652±21.24, 783±9.62 g/d with Ration-I and Ration-II, respectively. While feed intake (P>0.05) of concentrate, fodder and wheat straw was 2.35±0.05, 2.51±0.07; 8.81±0.23; 9.38±0.22 and 1±0.00, 1.03±0.04 kg/d with Ration-I and Ration-II, respectively. Regarding serum profile cholesterol concentration (P<0.05) was found to be 55.86±0.33 and 56.87±0.72 with Ration-I and Ration-II, respectively. The results indicate that buffalo calves have a great growth potential which can be manipulated by modern husbandry practices.
