    ABSTRACT: A 120 day growth trial was conducted using 20 Murrah buffalo calves (Avg. b.wt.71±1.6kg) by randomly allotting them to four groups of 5 animals each to study the effect of replacing soybean meal with shrimp waste meal at 0, 10, 20 and 30 % levels on growth performance, serum biochemical profile and on nutrient digestibility. Amino acid and fatty acid composition of shrimp waste meal was determined. In vitro studies were conducted to evaluate the digestibility of shrimp waste meal. Chemical composition (% DMB) indicated that shrimp waste meal was rich source of crude protein. Amino acid composition revealed that shrimp waste meal used in the present study is rich source of serine. Fatty acid composition indicated that shrimp waste meal is rich in saturated fatty acids and also possesses considerable quantities of mono and polyunsaturated fatty acids which accounts for 34.86 % of total fatty acids. In vitro digestibilities of DM and CP 71.80 and 68.82 %, respectively, for shrimp waste meal. The body weight gain and average daily gains were higher in shrimp waste meal incorporated groups as compared to control. However, body weight gain and average daily gains were significantly (P<0.05) higher at 10 % replacement level. The feed conversion ratio and feed cost/ kg gain were 7.90 and 106.18; 4.75 and 70.81; 6.60 and 86.74 and 7.02 and 91.95, respectively, for T1, T2, T3 and T4 groups. The digestibilities of DM, OM, CP, EE, CF, NFE, NDF, ADF, hemicellulose and cellulose increased (P<0.01) in Murrah buffalo calves where shrimp waste meal was incorporated. However, higher digestibilities were observed at 10 % replacement level. The DM, DCP and TDN intakes of buffalo calves of all the groups were higher than the recommendations of ICAR (1998) indicating the adequacy and palatability of calf starters. The serum total protein increased significantly (P<0.05) at 10 % level of inclusion of shrimp waste meal. The serum albumin levels were higher in shrimp waste meal incorporated groups than control group but significant (P<0.01) increase was observed at 10 % level of inclusion of shrimp waste meal. However, dietary inclusion of shrimp waste meal at graded levels in calf starter diets had no effect (P>0.05) on serum globulin content. Blood urea nitrogen content was significantly (P<0.05) decreased at 10 % replacement level. The feed cost/kg gain decreased by Rs 35.37 (T2), 19.44 (T3) and 14.23 (T4) in calves fed calf starter diets containing shrimp waste meal at varying levels as compared to the control. Based on the present study, it is concluded that replacement of soybean meal protein in calf starter diets with shrimp waste meal at 10 % level resulted in improved digestibility of gross nutrients and growth rate of Murrah buffalo calves besides reducing the cost per kg gain by Rs 35.37.
