淮南猪数量性状遗传特性的研究——繁殖性状

Study on the Heredity of Quantitative Character of Huainan Swine——Reproductive Character

根据淮南猪原种场1985—1992年育种资料,系统研究了淮南猪繁殖性状的表型系数,遗传参数及繁殖性状与生长发育性状间的遗传参数.淮南猪繁殖性状的表型参数在国内地方品种中居较高水平,遗传力估计值大多较低.性状间相关研究表明:在评定母猪繁殖力时应将断奶窝重和产仔数作为两项主要指标来考虑.

On the base of breeding test data gainde by Huainan Swine farm in 1985-1992,mean population,heritability,phenotypic Correlation to the reproductive Characters of Huainan Swine are estimated. The Phonotypic Parameter of the reproductive Characters of Huainan Swine is in the rather high level among the Swine breeds at home,heritability is in rather low level. The Correlation among different characters are shown when elavuating dan swine reprocuctive Characters,We must consider two main indexes of weaning weight of litter and the number of piglets which were born alive.
