摘　　要：为研究日粮中不同含量葵花籽皮对母猪的饲喂效果,将36头妊娠经产母猪随机分为4组(对照组和试验1组、2组、3组),在基础日粮中添加不同含量的葵花籽皮(0、4%、7%、10%),测定葵花籽皮对母猪繁殖性能的影响。结果表明,各组母猪的平均采食量差异均不显著;试验1组和试验2组能显著改善母猪的繁殖性能,以试验2组母猪的繁殖性能、维持背膘厚度和体质量的效果最好。与对照组相比,试验2组母猪的窝均产仔数提高0.7头,窝均初生质量提高0.83 kg,断奶存活率提高2.33个百分点,窝均断奶质量提高12 kg,发情间隔缩短2 d,哺乳期背膘厚度下降5.0 mm,整个繁育周期平均体质量下降12 kg。综上,饲粮中葵花籽皮的最佳用量为7%。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%.
