The purpose of present investigation was to find out the optimum level of crushed tamarind seed, to evaluate the chemical composition of feed stuff, to determine the dry matter intake, growth performance of growing calves and to work out the economic cost.The study entitled “Effect of feeding crushed tamarind seed on growth performance of growing calves” was conducted for period of 90 days. Twenty growing calves were divided into five groups on the nearness of age and weight. Four feeding treatments were studied namely T1 (Dry roughages + Green fodder + Concentrate), T2 (Dry roughages + Green fodder + 80% Concentrate + 20 % crushed tamarind seed), T3 (Dry roughages + Green fodder + 60% Concentrate + 40 % crushed tamarind seed), T4 (Dry roughages + Green fodder + 40% Concentrate + 60 % crushed tamarind seed. It was observed that the concentrate offered to the calves during experiment period by mixing with crushed tamarind seed were containing 90.20, 18.55, 6.44, 6.8, 60.98 and 7.23 per cent of DM, CP, EE, CF, NFE and Total ash, respectively. Daily DM intake differed significantly between the treatments. The calves from T3 groups consumed more DM than that of T4, T2 and T1 calves groups. The average daily DM intake was 1.96, 2.01, 2.08 and 1.99 kg/day/calves in T1, T2, T3 and T4 groups respectively. This trend thus indicated that there was increase in the daily DM intake when a crushed tamarind seed was incorporated as concentrate in the rations of calves. Weight gain per day per calves was found higher in treatment T3 (60 % concentrate + 20 % crushed tamarind seed). All the calves exhibited satisfactory growth rate of 0.238 to 0.296 kg per day and differences were significant. The per kg gain of body weight was higher in T3 treatment. It was over experimental result, the treatment T3 showed better and desirable result as compared with T1, T2 and T4 treatment. Therefore feeding cost was desirable (Rs.561.69) in T2 treatment. Growth rate was higher in calves when fed 60% concentrate mixture with 40 % crushed tamarind seeds in treatment T3 group than other group of treatment T1, T2 and T4 respectively.enGrowing Calves, Calves rearing technique, Growth performance of calves, Tamarind seed.Thesis
