| 摘 要： | 利用MTDFREML软件包估计大约克双肌臀种猪活体背膘厚遗传力。首先用SAS软件包对固定效应进行不同水平间差异显著性检验 ,尔后确定固定效应的水平数 ,最后用MTDFREML进行遗传参数估计 ,得出大约克双肌臀种猪 1 0 0kg体重时活体背膘厚遗传力的估值。这对于大约克双肌臀种猪的育种实践将起到一定的促进作用。

| Abstract: | MTDFREML software was used to estimate the heritability of back fat alive on double muscle Large Yorkshire swine.SAS software was first used to test the differences of different levels,and then levels of each fix effect, MTDFREML was finaly used to estimate genetics parameter.This paper reported the estimated value of heritability of back fat alive at 100 kg weight in double muscle Large Yorkshire swine which may accelerate the breeding practice of double muscle Large Yorkshire swine. |
