| 摘要: |
| 为探讨非遗传因素对西门塔尔母牛主要经济性状的影响规律，利用新疆呼图壁种牛场1989-2014年间共1 492头西门塔尔牛的生产性能记录，分析了不同胎次、产犊年份、产犊季节、产犊年龄对西门塔尔牛305 d产奶量、体高、硬长、软长、胸围、腹围、尻宽、尻长、腿围、管围、体重和外貌评分的影响，并进行了最小二乘分析。结果表明：不同胎次、产犊年份、产犊年龄对西门塔尔牛305 d产奶量、体高、硬长、软长、胸围、腹围、尻宽、尻长、腿围、管围、体重和外貌评分有极显著的影响（P<0.01）；不同产犊季节对西门塔尔牛305 d产奶量、体高、胸围、尻宽、尻长、腿围、管围、体重和外貌评分有极显著的影响 （P<0.01），对硬长、软长、腹围没有显著的影响（P>0.05）。 |

| Abstract: |
| In order to investigate the influence of non-genetic factors on main economic traits of Simmental cattle,the production performance record of Xinjiang Hutubi cattle farm from 1989 to 2014 years were adopted,a total of 1492 Simmental cattle,effects of the factors including parity differences,calving years,calving seasons,age of calving on the main economic traits,e.g.305 days of milk yield,body height,body length(hard),body length(soft),chest girth,circumference of abdomen,rump width,rump length,leg circumference,cannon circumference,body weight and type classification of Simmental cattle were analyzed by least square analysis.The results showed that:different parity,calving year and age of calving had a significant effect on the main economic traits in Simmental cattle (P>0.05).While different calving seasons had a significant effect on the 305 days of milk yield,body height,chest girth,rump width,rump length,leg circumference,cannon circumference,body weight and type classification (P<0.01),it had no significant effect on body length(hard),body length(soft),circumference of abdomen (P>0.05).This study provided a theoretical basis for Simmental cattle breeding value estimation and breeding objectives program. |
