This study was conducted to investigate the effects of dry period different parities (2nd, 3rd and >= 4th) and 800 calves delivered by these >= 71 days). Calves were weighed and body dimensions (body length, were significant relationships between DPL and calf gender (P<0.01). The cows with DPL of 51-60 days had greater female calf ratios and the cows with DPL of 61-70 days had greater male calf ratios. In the study, the relationship between calves' body weights (birth and 6th month) and DPL was found to be significant at P<0.01 level, and the month wither height) and DPL was significant at P<0.05 level. These values the highest were observed in the calves of the cows with DPL 61-70 days. The relationship between calves survivability, mortality values and DPL was not significant (P>0.05). The results obtained from the study showed that the dry period length of the cows can be planned between 61-70 days, considering the body weight and growth performance of the calves.
