摘要

对红河州某猪场1 562窝长大母猪、1 479窝PIC母猪妊娠期进行研究,探讨妊娠期对母猪繁殖性状影响。结果表明,长大母猪、PIC母猪妊娠期分别为115.26天、115.39天;长大母猪的妊娠期主要集中在115～117天(占75.42%),PIC母猪的妊娠期主要集中在114～116天(占65.93%),妊娠期在113天以下、116天以上的母猪逐渐减少;长大母猪妊娠期以4胎最短(平均为112.85天),显著或极显著少于其它胎次,PIC母猪的妊娠期以3、4胎较短(平均为114.73天、114.32天),各胎次间差异不显著(P>0.05);长大母猪以妊娠期114～116天产仔数和产活仔数最多、初生窝重较大;PIC母猪以妊娠期113～116天产仔数和产活仔数最多、初生窝重最大。
        The effects of gestation period on reproductive traits of sows were studied by studying the gestation period of 1 562 litters of LY sows and 1 479 nests of PIC sows in a pig farm in Honghe Prefecture. The results showed that the gestation period of LY sows and PIC sows was 115.26 days and 115.39 days respectively(P>0.05); the gestation period of LY sows was mainly concentrated in 115-117 days(75.42%), and the gestation period of PIC sows was mainly Concentration 114-116 days(65.93%), 113 days or less, more than 116 days gradually reduced; LY sows with 4 fetuses as the shortest(average 112.85 days), significantly smaller than other parity(P<0.01, P<0.05). The gestation period of PIC sows was the shortest in 3 and 4 fetuses(average 114.73, 114.32days), and the difference between each fetus was not significant(P >0.05); the total number of litters and live births of LY sows is the highest at 114-116 days and the largest at birth; the total number of litters and live births of PIC sows is the highest at 113-116 days and the largest at birth.
