To assess the effect of starting time of feeding milk replaced (MR), thirty-two newborn Holstein calves (initial weight 43±0.7 kg) were used. The animals were divided into four groups (n=8) in which the control group (g1) was fed cow milk. The other groups were offered MR either on 5 (g2), 13 (g3) or 20 days (g4) after birth. The whole trial lased for two months. The average daily gain (ADG), starter intake (SI) and water intake (WI) were measured fortnightly. Fecal scores (FS) were determined daily throughout the trail. The data were statistically analyzed using completely randomized design. At the end of the trail, there was no significant difference observed in the performance of calves in any of the groups. However, animals in g3 had the highest ADG, SI and WI among those fed MR.
