安秦F_1代、和秦F_1代与秦川牛生长性能比较

Growth Performance Comparison of F_1 from Angus and Qinchuan,Wagyu and Qinchuan and Qinchuan Cattle

[目的]为探讨安秦F1代与和秦F1代与秦川牛的生长发育情况。[方法]选择安秦、和秦、秦川公牛各10头作为2个试验组和1个对照组,测定6、12、18、24月龄的空腹体重、体长、体高、胸围数据,并进行比较分析。[结果]表明,在集约化饲养条件下,6～24月龄的安秦F1代体重及各项体尺指标,均显著高于秦川牛(P<0.05),和秦F1代均显著高于秦川牛(P<0.05),而安秦F1代与和秦F1代各项指标差异不显著(P>0.05)。[结论]安秦F1代、和秦F1代的生长发育速度均比秦川牛快,安秦F1代与和秦F1代生长发育速度差异不显著。

【Objective】The growth performances of F1 from Angus×Qinchuan,Wagyu×Qinchuan and Qinchuan cattle were measured.【Method】Each 10 bulls from Angus×Qinchuan and Wagyu×Qinchuan were selected as the test groups,and 10 Qinchuan bulls were as the control.The empty stomach body weight,body length,body height and chest circumference were detected and comparatively analyzed at the age of six,twelve,eighteen and twenty-four months old.【Result】The F1 from Angus×Qinchuan cattle and Wagyu×Qinchuan cattle were better than Qinchuan cattle in all the measured traits under intensive rearing conditions（P0.05）.The difference between the hybrids was not significant（P0.05）.【Conclusion】The growth and development speed of the hybrids was faster than that of Qinchuan cattle,but there were no significant difference between the hybrids.
