Body Condition Score (BCS) system is a subjective scoring method of evaluating the energy reserves of dairy animals which provide the better understanding of biological relationship between body fat, milk production and reproduction that helps in adopting the optimum manage mental practices to derive maximum production and maintain better health status. The effect of BCS at calving on the reproductive performance studied in 24 buffaloes in a 4 x 6 CRD showed increase in body weight of 38.50 kg was observed for every one unit increase of BCSc between BCSc groups of 2.5 – 2.99 and 3.5 – 3.99 and 22.33 kg between BCSc groups of 3.0 – 3.49 and 4.0 – 4.49. Buffaloes of BCSc above 3.5 with significantly (P < 0.01) higher body weights showed better reproductive performance compared to buffaloes of BCSc groups below 3.5 with less body weights. The prepartum and weekly postpartum changes in BCS studied showed that the buffaloes gained a BCS of 0.38 from 3 months prepartum to one week prepartum, lost 0.72 ± 0.05 BCS due to calving, further showed a decline in BCS upto 8-9 weeks of postpartum and then started regaining BCS gradually until 18 weeks postpartum. The mean LBCS over the period of 18 weeks postpartum was comparatively higher (0.72 ± 0.05) than BCS restored in the early lactation which was shown as GBCS (0.12). The difference of 0.34 units between LBCS and GBCS was observed over a period of 18 weeks postpartum. The monthly postpartum changes in BCS showed that BCS decreased from calving to two months of lactation and then gradually increased.
