This study was conducted with an objective to find the relation between pre-partum dry period and body weight or milk yield at 1-month post-calving. The recordings were made by using data records of seven buffalo farms in and around Nellore district of Andhra Pradesh. Only the buffaloes with proper records and identification measures were taken into account. According to the collected dry period data, the average body weight and milk yield at 1-month post-partum were higher in the buffaloes with larger dry period (>2 months) compared to smaller dry periods (<2 months). The predicted equation generated for short dry period group of buffaloes is Y = -16.747 + 0.290 (DP) + 0.015 (BW), while the same for long dry period group is Y = 11.937 - 0.035 (DP) + 0.013 (BW). The coefficient of determination (R-squared) was higher for short dry period buffaloes compared to those with long dry period. Significant (P<0.01) positive correlations were observed for dry period with body weight and milk production. In conclusion, the dry period of more than 2 months is required in buffaloes to obtain higher milk yield in subsequent lactation. Further, the regression and correlation studies project pre-partum dry period and body weights as good predictors for post-partum milk yield.
