| 摘 要： | 试验资料取自金华猪场 1 979～1 999年金华猪繁殖性能的生产记录。采用动物模型约束性最大似然法 (REML)对该猪群的遗传参数进行估计 ,测定 1 1 4 4头纯繁金华母猪的产仔哺育记录。结果表明 ,产仔数 (TNB)、产活仔数 (NBA)、初生重 (PBW)、初生窝重 (LBW)、 2 0日龄头数(NFC)、 2 0日龄窝重 (LWFC)、 2 0日龄重 (PWFC)、 60日龄头数 (NW)、 60日龄窝重 (LWW)、 60日龄重 (PWW)、乳头数 (TN)的遗传力分别为0 1 2± 0 0 9、 0 1 8± 0 1 1、 0 1 5± 0 0 9、 0 0 2± 0 0 9、 0 1 0± 0 1 1、 0 0 8± 0 1 3、 0 1 8± 0 1 0、 0 2 3± 0 1 1、 0 31± 0 1 3、 0 35± 0 1 1和 0 1 9± 0 1 0。TNB与NBA、LBW、NW、LWW的遗传相关范围为 0 66～ 0 88,TNB与PBW的遗传相关为 - 0 43。NBA与LBW、NW、LWW的遗传相关范围为 0 60～ 0 64,NBA与PBW遗传相关为 - 0 63。PBW与PWW的遗传相关为 0 51。

| Abstract: | The reproductive data of 1 144 Jinhua sows between 1979 to 1999 from an experimental farm for swine breeding stock in Jinhua were used to estimate the genetic parameter by animal model procedures using restricted maximum likelihood (REML). The result showed that the heritabilities of total number of pigs born (TNB), number born alive (NBA), average pig birth eight (PBW), litter birth weight (LBW), number at 20 day (number at first creep NFC), litter weight at 20 day (litter weight at first creep LWFC), average weight at 20 day (average pig weight at firat creep PWFC), number at 60 day (number at weaning NW), litter weight at 60 day (litter weaning weight LWW), average weight at 60 day (average pig weaning weight PWW) and teat number (TN) were 0 12±0 09,0 18±0 11,0 15±0 09,0 02±0 09,0 10±0 11,0 08±0 13,0 18±0 10,0 23±0 11,0 31±0 13,0 35±0 11,and 0 19±0 10,respectively. The genetic correlation between TNB with NBA, LBW, NW, LWW were ranged from 0 66 to 0 88, TNB with PBW was -0 43. The genetic correlation between NBA with LBW, NW, LWW were ranged from 0 61 to 0 64, NBA with PBW was -0 63. There was a middle high degree genetic correlation (0 51) between PBW and PWW. |
