摘　　要：为测定不同终端父本与三系母猪的配合力差异,选择温氏集团常用的2种终端父本S121和S122,与W352系母猪进行配种,比较不同终端父本生产五系配套肉猪的配套效果,以选择合适的终端父本,并进行2次重复配合力测定试验。结果表明,与WS502配套系肉猪相比,WS501配套系肉猪在生长速度、料重比、肉色及大理石纹和上市大体重等方面均具有优势;WS501系配套肉猪体型高长、头腮较小、背宽、肌肉紧凑、收腹良好、群体一致性好。饲养WS501系配套肉猪具有更好的经济价值。In order to determine the difference of combining ability between different terminal sires and three line sows,two commonly used terminal sires S121 and S122 from Wens Group were mated to W352 sows,the mating effects of five-line pigs from different terminal sires were compared to select the appropriate terminal sire through two repeated tests of combining ability.WS501 hybrid pig had advantages in body length,growth rate,feed/gain ratio,meat color,marbling and big market weight compared with WS502 hybrid pig.The results showed that WS501 hybrid pig had long and tall body length,small head,wide back,compact muscle,good abdomen and group uniformity.Feeding WS501 hybrid pig has the better economic value.
