| 摘 要： | 利用最小二乘线性模型对西门塔尔杂种母牛各杂交代次的产奶量及其产犊效果进行评估，确定了在丰定县饲养条件下的西门塔尔杂种母牛适宜级进杂交代数为３代，从而为西门塔尔母牛产奶和产犊的综合利用，以及西门塔尔牛的杂交改良奠定了理论基础。 |
| 关 键 词： | 西门塔尔牛 杂交代次 线性模型 |

| Abstract: | Effect of milk yield and calf weight each generation in Simmental hybrid cow were evaluated by least square analysis linear model.In feeding condition of Fengning region,suitable generation of upgrading in Simmental hybrid cow was selected,it is three generation of simmental hybrid cow,This result has established foundation for producting milk meat calf and crossbreeding and improving in simmental crossbred. |
| Keywords: | Cattle Generation of crossbred Upgrading Linear model |
