An experiment was conducted to investigate the effect of dietary supplementation of nano zinc oxide (nZnO) on growth performance in crossbred calves. Twenty four crossbred calves of about 6 months age were randomly divided into four groups (Control, Treatment1, Treatment2 and Treatment3) of six calves each. The Control (C) group was fed with basal diet, T1 was supplemented with 25ppm ZnSo4, T2 and T3 were supplemented with 5ppm and 10ppm nZnO respectively, along with the basal diet. The results affirm that the body weight gain (kg) and average daily gain (g/day) were significantly (P<0.01) higher in T3 group followed by T2 and T1 and lowest in control group. The cost per kg weight gain (Rs) was lowest in T3 followed by T2 and T1 while highest in the control group. The present study concluded that economic growth rate can be achieved by supplementing nZnO at 10ppm level in crossbred calves.
