摘要
选择年龄、胎次、泌乳期相近的澳牛与我国本地奶牛各30头,采用单因素对比试验方法,测定澳牛与本地奶牛在全混日粮(TMR)饲养条件下体尺、体重及生产性能的差异。结果发现:澳牛与本地奶牛的体尺、体重相差不大,但澳牛的泌乳量、乳脂量和乳蛋白量均略优于我国奶牛。试验证明,在良好的饲养条件下,澳牛具有良好的生产性能。
In this study, 30 Australian Holstein cows and 30 Chinese cows were sampled to measure about the body measurement traits, body weight and production trait under TMR breeding conditi on. The results showed that the different of the body measurement traits and body weight was not significant between different treatments, but Australian Holstein cow was better than Chinese cows in milk yield and fat yield and lacto-protein yield, the experiment proved that Australian Holstein cow should have better production performance if had the better breeding condition.
