Effect of Varying Energy and Protein Levels in Pelleted Complete Diets on Rumen and Blood Parameters in Goats

Twelve non descript local goats, randomly divided into two groups, were fed complete feed pellets (8 mm diameter) T₁ (12% CP, 55% TDN), T₂ (14% CP, 60% TDN) upto 150 days of experiment. Roughage to concentrate ratio was maintained at 60:40 with arhar straw as basal roughage. The rumen and blood biochemical profile were studied at monthly intervals. The rumen liquor parameters varied significantly (P < 0.0.1) between the treatments except for pH. The average values for rumen liquor pH, NH₃-N, TVFA, total nitrogen, TCA-ppt-N and NPN for T₁ and T₂ groups were 6.25 and 6.33, 15.09 and 21.94 mg/100 ml SRL, 10.93 and 12.24 m mol/100 ml SRL, 70.12 and 99.51 mg/100 ml SRL, 33.84 and 53.63 mg/100 ml SRL and 36.46 and

45.84 mg/100 ml SRL, respectively. The blood biochemical parameters also varied significantly (P < 0.01) except for the serum calcium. The mean values for T₁ and T₂ groups were, glucose

(62.52 and 53.67 mg/dl), total serum protein (6.20 and 7.06 g/dl), serum albumin (3.25 and 3.89 g/dl), serum globulin (2.94 and 3.16 g/dl), total lipids (349.79 and 426.18 mg/100 ml), serum calcium (10.59 and 10.38 mg/dl) and serum phosphorus (4.82 and 5.63 mg/dl).
