Abstract
The main purpose of this article is to explore the effects of different proportions of dietary fiber added from different sources during pregnancy and lactation on the reproductive performance of sows,and to use this as a basis to guide the application of dietary fiber in the breeding process of sows.This study adopted a single factor experimental design,selecting 48 healthy,parity,and weight similar growing binary sows.They were randomly divided into three experimental groups:Group A(control group,23%wheat husk was supplemented with compound feed during pregnancy and 5%wheat husk was supplemented with compound feed during lactation),Group B(compound feed with 8%dietary fiber to get Deyishu F10 during pregnancy and 2%dietary fiber to get Deyishu F10 during breastfeeding)and Group C(10%dietary fiber to get Deyishu F10 during pregnancy and 4%dietary fiber to get Deyishu F10 during breastfeeding),Sixteen replicates per group with one sow per replicate.The experiment started from sow breeding and ended 10 days after weaning,about 152 days.The experimental results showed that compared with the control group,groups B and C could increase the total litter size,live litter size,and qualified litter size of pregnant sows,and there was an upward trend with the increase of dietary fiber addition;Groups B and C significantly reduced the labor process and fecal score of pregnant sows(P<0.05);Group C significantly increased the birth weight of piglets;Groups B and C significantly boosted the feed consumption of lactating sows and the growth in weight of piglets post weaning on a daily basis(P<0.05),and significantly shortened the estrus interval(P<0.05).Conclusion:Adding dietary fiber to the diet of pregnant and lactating sows can increase the total litter size,qualified litter size,and piglet birth weight of pregnant sows,shorten the delivery process,and improve constipation problems;Improve the feed intake of lactating sows and weaning weight of piglets,and shorten the estrus interval.关键词
