The body condition score (BCS) system is a subjective scoring method of evaluating the energy reserves of dairy animals to provide better understanding of biological relationships between body fat, milk production and reproduction. This method helps in adopting the optimum management practices to derive maximum production and maintain optimum health of the livestock. In this study, a new BCS system was developed for Murrah buffaloes. The skeletal check points were identified by studying the anatomical features and amount of fat reserves in slaughtered animals. The scores were assigned from 1 to 5 based on the amount of fat reserves in slaughtered animals. A score of 1 represents least and 5 represents most amount of fat. The skeletal check points identified were ordered based on the amount of carcass fat reserves and scores assigned to prepare a preliminary BCS chart on a 1 to 5 scale at 0.25 increments. The BCS chart was further modified by eliminating the skeletal check points at which the fat reserves were less evident on palpation in most of the buffaloes and a new BCS chart on a 1 to 5 scale at 0.5 increments examining eight skeletal check points was developed. The new BCS system developed was tested for precision in 10 buffaloes for each point of the 1-5 scale by ultrasonographic measurements of body fat reserves. Ultrasonographic measurements showed that as the BCS increased, the amount of fat reserves also increased (p < 0.01), indicating that the BCS adequately reflected the amount of actual fat reserves. BCS was significantly correlated (r = 0.860) with the carcass fat reserves as well as the ultrasonographic fat reserves (r = 0.854).
体况评分（BCS）系统是一种评估奶牛能量储备的主观评分方法，有助于更好地理解体脂、产奶量和繁殖之间的生物学关系。该方法有助于采用最佳管理措施，以实现最大产量并维持家畜的最佳健康状态。在本研究中，为摩拉水牛开发了一种新的BCS系统。通过研究屠宰动物的解剖特征和脂肪储备量来确定骨骼检查点。根据屠宰动物的脂肪储备量，将分数从1到5进行分配。1分表示脂肪最少，5分表示脂肪最多。根据胴体脂肪储备量和分配的分数对确定的骨骼检查点进行排序，以编制一个1至5分制、增量为0.25的初步BCS图表。通过剔除大多数水牛触诊时脂肪储备不明显的骨骼检查点，对BCS图表进行了进一步修改，并开发了一个1至5分制、增量为0.5、检查八个骨骼检查点的新BCS图表。通过对1-5分制每个分数点的10头水牛进行体脂储备的超声测量，对开发的新BCS系统进行了精度测试。超声测量结果表明，随着BCS的增加，脂肪储备量也增加（p<0.01），这表明BCS充分反映了实际脂肪储备量。BCS与胴体脂肪储备以及超声脂肪储备显著相关（r=0.860）（r=0.854）。
