A study was conducted to assess the effect of feeding compressed complete feed block (CCFB) containing 5% guar meal on the blood biochemical profi le in the crossbred (CB) calves. Twelve growing crossbred male calves (6-10 months old), were selected

and divided into two groups (six in each) by using paired random design. The control group (T1) was fed CCFB alone while treatment group (T2) was fed with CCFB containing 5% guar meal. Both the diets were iso-nitrogenous and were formulated to meet the requirement of 600 g/d average daily gain. The study was conducted for 120 days. Blood was collected to harvest the serum and serum metabolites were analyzed using standard protocol. The mean values for Hb (mg/ dl), serum glucose (mg/ dl), total protein (g/dl), albumin (g/dl), globulin (g/dl), A: G ratio, SGOT, SGPT (IU/L) and serum urea-N (mg/dl) of all the experimental CB calves were found to be statistically similar with that of the control group. It is concluded that the inclusion of guar meal at 5% in CCFB has no any adverse effect on the blood biochemical profi le in the CB calves in long term feeding.
