This study was designed to investigate the relationship of temperament with oestrus, resumption of ovarian cyclicity and milk yield in post-partum buffaloes. For this study, 102 post-partum Murrah buffaloes were observed for temperament in open paddock and during milking. Based on the temperament score (1-5 score), they were classified into docile, slightly restless, restless, aggressive and nervous. Oestrous behaviour was monitored twice daily in all the buffaloes along with milk yield (weekly), body weight (BW) and body condition score (BCS) at day 0, 30, 60 and 90 post-partum. Based on the temperament score, the number of buffaloes classified as docile, slightly restless, restless and aggressive was 37 (36.27%), 28 (27.45%), 30 (29.41%) and 7 (6.86%), respectively, but none under nervous category. Number of buffaloes resuming cyclicity in various temperaments groups were as follows: docile (n = 35; 94.59%), slightly restless (n = 22; 78.57%), restless (n = 20; 66.67%) and aggressive (n = 7; 85.71%). Temperament was not correlated (p = .128; r=-.152) with oestrous behaviour. But, temperament was correlated (p < .0001; r = .384) with the resumption of cyclicity as docile and slightly restless buffaloes resumed cyclicity (p < .0016) earlier. Temperament of buffaloes was weakly correlated (p = .0017; r=-.306) with milk production with higher (p < .0358) total milk yield in docile (1022 ± 23.75 kg) and slightly restless buffaloes (948 ± 35.86 kg) as compared to other temperament groups. In summary, temperament of post-partum buffaloes was related with resumption of ovarian cyclicity and milk yield, but not oestrous behaviour.
本研究旨在调查产后水牛的性情与发情、卵巢周期恢复及产奶量之间的关系。在本研究中，对102头产后摩拉水牛在露天围场和挤奶期间的性情进行了观察。根据性情评分（1 - 5分），将它们分为温顺、稍不安、不安、好斗和神经质五类。对所有水牛每天观察两次发情行为，并在产后第0、30、60和90天记录产奶量（每周）、体重（BW）和体况评分（BCS）。根据性情评分，被归类为温顺、稍不安、不安和好斗的水牛数量分别为37头（36.27%）、28头（27.45%）、30头（29.41%）和7头（6.86%），但没有水牛属于神经质类别。不同性情组中恢复发情周期的水牛数量如下：温顺组（n = 35；94.59%）、稍不安组（n = 22；78.57%）、不安组（n = 20；66.67%）和好斗组（n = 7；85.71%）。性情与发情行为无相关性（p = 0.128；r = -0.152）。但是，性情与发情周期恢复相关（p < 0.0001；r = 0.384），因为温顺和稍不安的水牛恢复发情周期更早（p < 0.0016）。水牛的性情与产奶量弱相关（p = 0.0017；r = -0.306），温顺（1022 ± 23.75 kg）和稍不安的水牛（948 ± 35.86 kg）的总产奶量高于其他性情组（p < 0.0358）。总之，产后水牛的性情与卵巢周期恢复及产奶量有关，但与发情行为无关。
