This study was aimed to investigate the effect of different levels of dietary protein on growth of female Holstein calves during the post weaning period. An average of 60 days old 20 female Holstein Friesian calves were used for the experiment. Calves were divided into two groups; while first group received feed containing 18% CP, second group received feed containing 22% CP. The results showed that concentrate fed protein levels were did not affect live weight (LW) of the calves (138.45 vs 157.50 kg). The BM were found 100.65 vs 102.40 cm for body length (BL), 101.45 vs 106.60 cm for wither height (WH), 45.55 vs 45.80 cm for body depth (BD), 106.90 vs 109.20 cm for hip height (HH), 30.85 vs 31.95 cm for hip width (HW) and 115.85 vs 121.55 for chest girth (CG) (P> 0.05). The results showed that, better performance has observed in calves fed with %22 CP
