Abts ratc:In this study,5164 litters of reproductive performances of Yorkshire and Duroc sows were compared.The results showed that the delivery birth time, number of healthy piglets,number of dead fetuses , number of mummy,number of survival pig -lets,number of dead piglets , sum of born piglets,number of adopted piglets , number of sent piglets, litter weight of birth, number of male piglets weaned at 21 days, number of female piglets weaned at 21 days, sum of piglets weaned at 21 days, and 21-day-old litter weight of Yorkshire sows were increased respectively by 24.35%, 14.55%, 98.00%, 50.00%, 14.55%, 94.74%, 19.01%, 116.67%, 133.33%, 12.22%, 8.51%, 17.73%, 13.08%and 12.46%as compared with those of Duroc sows, and the differences in these indexes between two kinds of sows were extreme significant ( P<0.01) .The fetation duration of Duroc sows was 0.20%lon-ger than that of Yorkshire sows (P<0.01).The survival rate of sucklings of Duroc sows was significantly (P<0.05) increased by 0.63%as compared with that of Yorkshire sows.In spring, summer, autumn and winter, the number of healthy piglets, number of born survival piglets, sum of born piglets, sum of piglets weaned at 21 days, and 21-day-old litter weight of Yorkshire sow group were very significantly higher than those of Duroc sow group.
