| 摘 要： | 本研究对农户饲养条件下的984头威宁黄牛及西×威F1、安×威F1、利×威F1初生、6月龄、12月龄、18月龄、24月龄的体尺、体重进行了测定。结果表明:(1)西×威F1、安×威F1、利×威F1代牛的体斜长、胸围、体高、管围和十字部高分别平均增加16.69%~22.25%,20.20%~25.93%,16.38%~20.46%,18.03%~28.46%,15.96%~19.80%(P<0.01);(2)杂交F1代♂牛24月龄体重平均提高76.46%(P<0.01),日增重平均提高78.76%,生长系数平均提高12.13%;杂交F1代♀体重提高80.54%(P<0.01)、日增重平均提高67.16%,生长系数平均提高7.18%;(3)三种杂交F1代牛之间体尺差异不明显(P>0.05),增长速度以安×威F1提高幅度最大(P<0.05)。从而认为,用安格斯牛、西门塔尔牛、利木赞牛改良威宁黄牛可以取得良好的杂交效果,其中以用安格斯牛改良的效果更为明显。

| Abstract: | The body size and weight of 984 Weining yellow cattle and crossbreds of Weining yellow cattle with either Simmental or Angus or Limousin at the age of birth,6,12,18 and 24 months fed under the local household condition in Guizhou province were measured to investigate the crossbreeding effects on Weining cattle.The result indicated that the body length,heart girth,body height,cannon circumference,hip height of all crossbreds increased(P < 0.01) by 16.69% to 22.25%,20.20% to 25.93%,16.38% to 20.46%,18.03% to 28.46%,15.96% to 19.80%, respectively;the average body weight,body weight gain,and growth coefficient of male crossbreds at 24 month of age increased by 67.16%,78.76%,and 12.13% compared with Weining yellow cattle,respectively;there was no significant difference in body size between crossbreds and Weining yellow cattle(P > 0.05),the crossbreds of Angus and Weining cattle showed the greatest growth rate.The result suggested that the crossbreeding of Weining cattle with either Angus or Simmental or Limousin could obtain the best improvement,and the Angus was the first choice sire breed in the crossbreeding of Weining yellow cattle. |
