| 摘 要： | 本文采用云南省肉牛与牧草研究中心杂交选育的热带亚热带肉牛BMY和纯种婆罗门(Brahman,简称B)2000至2003年的资料,配合动物模型应用MTDFREML软件进行初生重和6月龄体重两个性状的遗传力估计,结果为BMY的初生重、6月龄体重、B的初生重,6月龄体重遗传力分别是:0.34、0.16、0.36、0.13。

| Abstract: | Heritability of birth weight and 6-month weight were estimated by MTDFREML for BMY, a tropical and subtropical beef cattle, and Brahman (B) in this paper. The data was collected in Yunnan Beef Cattle and Pasture Research Center from 2000 to 2003. Animal model was applied in the research. Results showed that Heritability of birth weight and 6-month weight of BMY were 0. 34 and 0. 16, respectively. And Heritability for the two traits of B was 0. 36 and 0.13, respectively. |
