Abstract：In order to study the feeding effect of different contents of sunflower seed hull in diet on sows,thirty-six pregnant sows were randomly divided into 4 groups (control group and experimental group 1,2and 3) with 0％,4％,7％ and 10％ sunflower seed hull in basal diet respectively,and the reproduction performance was measured.The results showed the reproductive performance of the group 1 and 2 were significantly improved based on the similar average feed intake.It was notable that the group 2 displayed the best performance in reproduction,the maintenance of backfat thickness and body weight.Compared with the control group,the litter size,birth weight,weaning survival rate and average litter weaning weight were increased by 0.7,0.83 kg,2.33 percentage points and 12 kg,respectively.Meanwhile,the estrous interval was shortened by 2 d,and the backfat thickness and average body weight decreased by 5.0 mm and 12 kg,respectively.In summary,the best amount of sunflower seed hull in the diet was 7％.
