Effect of protein and mineral supplementation on growth performance and nutrient utilization in black Bengal Goats. Animal Nutrition and Feed Technology, 23: 97–105. A feeding cum growth trial was conducted to assess the effects of proteinaceous diet along with mineral mixture on nutrient utilization and growth performance of Black Bengal goats under stall-feeding system. Eighteen female Black Bengal goats of average 5 months old were randomly divided into three groups. Animals were fed T1: low protein and low mineral diet as per farmers’ practice; T2: high protein and low mineral; T3: high protein and high mineral. Green fodder (hybrid napier) was provided to animals and concentrate and roughage ratio was maintained at about 40:60 level. The total DM intake (g/d) was higher (P<0.05) in T3 (488) than T1 (445) but at par with T2 (471). DM digestibility (%) in T3 (61.50) was higher (P<0.05) than T (54.75) and T2 (57.75). Similarly, OM, CP, EE, NDF, ADF and TCHO digestibility was higher in T3 thanT1 but at par with T2. Daily nutrient intake (CP, DCP, TDN) was higher (P<0.05) in T3 than T1 but at par with T2. Hb level was higher (P<0.05) in T3 than T1 and at par with T2. Serum glucose, total protein and albumin level were higher in T3 than T1 and T2 being at par. The average daily gain (ADG; g/d) was higher (P<0.05) in T3 (63.94) than T1 (39.40) and T2 (52.32). Feed gain ratio was better (P<0.05) in T3 (6.63) than T1 (9.96) and T2 (7.89). It was inferred that feeding goats with high protein diet through increasing the level of groundnut cake with mineral mixture improved the performance of goats.
