Experiment was conducted to determine the effect of different levels of protein in the diet on growth performance and body measurements of crossbred calves. For this trail eighteen newborn crossbred calves (Holstein Friesian 75% × Kankrej 25%) of either sex randomly and sequentially grouped into three groups. viz. T₁ (Commercial concentrate: 18% CP), T₂ (Commercial concentrate: 25% CP) and T₃ (Farm made concentrate: 25% CP) for period of 84 days (twelve weeks). The body weight and body measurements of calves was recorded at birth, then on weekly interval body weight was taken in the morning before feeding and watering and body measurements like heart girth, body length and height at withers of calves was recorded at biweekly interval till 84 days of age. In conclusion it was found that calves fed with commercial concentrate (T₂) were significantly (p<0.05) influenced positively than T₁ and T₃ in terms of mean body weight (kg), mean average daily gain (g) and total weight gain (kg/week). Similarly, body length (cm) was significantly (p<0.05) influenced by treatment and observed significantly (p<0.05) higher in animals of T₂ group as compared to T₁ and T₃ groups. However, mean biweekly gain in height at withers and body length was not influenced by treatment.
