摘　　要：为了研究胎次及其与配种季节和分娩季节共同作用对大白猪母猪繁殖性能的影响,试验选取了河南某种猪场7373窝大白猪母猪的产仔数据,包括总产仔数、活仔数、弱仔数、死胎数、出生窝重、断奶数、21日龄校正窝重7个指标,分析了胎次及其与配种季节和分娩季节共同作用对繁殖性能的影响,以及上述8个繁殖性能指标间的相关性。结果表明:2,3胎次的总产仔数、活仔数高于或显著高于其他胎次(P>0.05或P<0.05),3胎次的出生窝重显著高于其他胎次(P<0.05),产仔性能最好的是2,3胎次,其次是4,5胎次,较差的是1胎次和5胎次以上;春季配种时2,5胎次的总产仔数、活仔数、出生窝重高于或显著高于其他胎次(P>0.05或P<0.05),夏季、秋季配种时2,3胎次的总产仔数(秋季2胎次除外)、活仔数和出生窝重(秋季2胎次除外)高于或显著高于其他胎次(P>0.05或P<0.05),2胎次适宜在夏季配种,3胎次适宜在夏季、秋季配种,4胎次适宜在冬季配种,5胎次适宜在春季配种,1胎次和5胎次以上适宜在冬季配种;春季分娩时3胎次的总产仔数、活仔数高于或显著高于其他胎次(P>0.05或P<0.05),夏季、秋季和冬季分娩时2,3,5胎次的活仔数、出生窝重和断奶数总体高于或显著高于其他胎次(P>0.05或P<0.05),2胎次适宜在秋季分娩,3胎次适宜在冬季分娩,4胎次适宜在春季分娩,5胎次适宜在夏季分娩,1胎次和5胎次以上适宜在夏季分娩;除分娩季节与活仔数和出生窝重不显著相关外(P>0.05),胎次及其与配种季节和分娩季节交互作用均与7个指标呈显著或极显著相关(P<0.05或P<0.01);7个繁殖性能指标多数呈显著或极显著正、负相关(P<0.05或P<0.01)。说明产仔性能较好的2胎次适宜在夏季配种秋季分娩,3胎次适宜在夏季、秋季配种冬季分娩,4胎次适宜在冬季配种夏季分娩,5胎次适宜在春季配种夏季分娩;产仔性能较差的1胎次和5胎次以上适�In order to study the effects of parity,mating season and parity,farrowing season and parity on reproductive performance of Large white pigs,7373 litters of Large white sows from a pig farm in Henan Province were selected for this experiment,including 7 traits:total litter size,live litter size,weak litter size,stillbirths size,newbom litter weight,weaned piglets and corrected 21-day-old litter weight.The effects of parity,mating season and parity,farrowing season and parity on reproductive performance of Large white pigs and the correlations among the above 7 reproductive performance traits were analyzed.The results showed that the total liter size and live litter size of 2nd and 3rd parities were higher and significantly higher than those of other parities(P>0.05 or P<0.05);newborn ltter weight of the 3rd parity was significantly higher than that of other parities(P<0.05);the best performance were 2nd and 3rd parities,followed by 4th and 5th parities,and the worse were 1th and more than 5 parities.The total liter size,live litter size and newborn litter weight at 2th and 5th parities in spring mating were higher or significantly higher than those of other parities(P>0.05 or P<0.05);the total litter size(except 2th parities in autumn),live ltter size and newborn litter weight of 2nd and 3rd parities in summer and autumn were higher or significantly higher than those of other parities(P>0.05 or P<0.05).The 2nd parity was suitable for mating in summer;the 3rd parities was suitable for mating in summer and autumn;the 4th parity was suitable for mating in winter,and the 5th parity was suitable in spring;the lst parity and more than 5 parities are suitable in winter.The total litter size,live litter size of 3rd parity in spring parturition was higher and significantly higher than those of other parities(P>0.05 or P<0.05),and the live litter size,newborn litter weight and weaned piglets at 2nd,3rd and 5th parities in summer,autumn and winter were higher and significantly higher than those of other parities(P>0.05 or P
