摘　　要：为研究新安江水牛公牛和母牛的生长发育规律。对在放牧条件下的309头,0~48月龄新安江水牛进行体重和体尺测定,对不同月龄进行差异性分析,采用Logistic、Gompertz和Von Bertallanffy 3种生长曲线模型拟合体重变化,筛选出最佳模型,计算体重绝对生长量和相对生长量。结果表明,新安江水牛公牛和母牛在18月龄前体重与体尺处于快速增长阶段,但18月龄后公牛生长速度仍高于母牛。Von Bertallanffy模型对公牛和母牛的拟合效果最好,R~2均超过0.98。公牛在13.1月龄的拐点体重248.2 kg,母牛在10.6月龄的拐点体重216.3 kg。To study the growth and development patterns of Xin'anjiang buffalo bulls and cows.Weight and body size measurements were conducted on 309 Xin'anjiang buffaloes aged 0-48 months under grazing conditions,and differential analysis was performed on different ages.Three growth curve models,Logistic,Gompertz,and Von Bertallanffy,were used to fit weight changes.Select the best model to calculate the absolute and relative weight growth.The results showed that the weight and body size of Xin'anjiang buffalo bulls and cows were in a rapid growth stage before 18 month,but the growth rate of bulls were still higher than that of cows after 18 month.The Von Bertallanffy model has the best fitting effect on both bulls and cows,with R2 all exceed 0.98.Bulls have a turning point weight of 248.2 kg at 13.1 month,while cows have a turning point weight of 216.3 kg at 10.6 month.
