The study was conducted to assess performance of Calf starter on buffalo calf rearing. The study was conducted at Monpura of Bhola District and Baufol of Patuakhali, Bangladesh during January, 2020 to June, 2020. A total of 30 buffalo calves of about 6-10 days of age were selected randomly from study area and divided in two groups; having fifteen (15) calves in each .Calves were maintained under uniform managemental condition except milk feeding. The calves were weighed initially just after birth and 15days apart thereafter by a platform digital balance. Each calf was weighed in the morning before feeding. Analysis of variance revealed that FCR of the values of control group (5.37) was significantly higher (P<0.05) than that of treatment group (4.09).Variable costs to raise buffalo calves during 75 days of experiment were higher in treatment group (Tk. 10089±2840 than control group (Tk. 8830±401). Results considering for daily weight gain and FCR, it indicates that overall performance, calf starter group was found better than the conventional ration.
