Abstract: A total of 30 Murrah buffaloes of 1st to 5th parity were selected and distributed into three different groups based on their pre-calving BCS (before 2 months of expected date of calving) namely BCS Group L (<3.0), BCS group M (3-4) and BCS Group H (4.0 and above). Parameters observed during the study period were body condition scores, body weight, production performance (milk yield up to 24 weeks, Peak yield, Total milk yield, Milk composition at monthly interval viz. Fat%, Protein%, SNF%), Reproductive performance (Number of days to attain post-partum estrus, Service period, Number of services/ conception), body measurements (Height at wither, Height at chest from ground, Chest girth, Abdominal girth). and ultrasonographic measurements of body fat reserve at different checkpoints. Results of this study revealed that body condition score, body weight and body measurements were significantly (P<0.05) higher in BCS group H as compared to BCS group L and M throughout the study period (2 months precalving and 6 months postcalving). The animals of BCS group M shows better production performance in terms of higher monthly milk yeild during 24 weeks of lactation, higher total milk yield (1752.82, 2221.55 and 2140.76 in BCS group L, M and H respectively), higher peak yield (10.80, 14.69, 14.56 in BCS group L, M and H respectively). The animals of BCS group M showed better reproductive performance in terms of shorter postpartum estrus period (82.17, 69.86 and 96.70 in BCS group L, M and H respectively), a fewer services per conception (1.50, 1.21, 2.10 in BCS BCS group L, M and H respectively) and a shorter service period (98.33, 79.93 and 159.50 in BCS group L, M and H respectively). Thus the study revealed that BCS had a significant (P<0.05) effect on production performance as well as reproductive performance in experimental Murrah buffaloes. Correlation studies revealed a significantly (P<0.01) positive correlation between BCS and USG measurements of subcutaneous fat measurements at various body checkpoints. This shows that the body condition scoring system has a positive relationship with body fat in all three BCS groups. Similarly, a positive correlation was found between BCS and abdominal and heart girth in all three groups. Thus it can be concluded that buffaloes in BCS group M showed better performance in terms of production and reproduction traits as well as measurements of subcutaneous body fat reserve which was accessed by ultrasonography, showed a positive correlation with BCS. Hence, the BCS system is a valid, cheap and easier method to measure body fat reserves of a buffalo. Thus body condition scoring can be used as an ideal tool of support for reproduction, production and feeding management of buffaloes.
