饲粮中添加发酵虻浆对仔猪生长性能及肠道菌群的影响
Effects of fermented black soldier fly larval paste on growth performance and gut microbiota dynamics in piglets
摘要
Abstract
[Objectives]The utilization of waste resource as feed and health effects of black soldier fly(Her-metia illucens L.)larvae were studied to provide services for increasing production and profitability in the pig industry.[Methods]Fifteen weaned piglets were selected and evenly divided into three groups.The matured black soldier fly larvae(BSFL)was used as raw material to obtain fermented BSFL paste.The effects of adding 0,2.5%,and 5.0%fermented BSFL paste on the growth performance and gut microbiota of weaned piglets were investigated for 30 days.[Results]Adding 2.5%and 5.0%fermented BSFL paste resulted in an average weight gain rate of 110%and 105%for individual piglets,both significantly higher than that(99.7%)of piglet fed without fermented BSFL paste,indicating that there is a significant benefit of weight gain.Actinobacteria,Firmicutes,Bacteroidetes,and Proteobacteria became the dominant phyla in the fecal of tested piglets supple-mented with BSFL paste,while the enrichment abundance of Actinobacteria(Treponema)decreased,thereby re-ducing the risk of disease occurrence.The fecal consistency of piglets fed with BSFL paste significantly im-proved,indicating that the function of digestion and absorption is enhanced.Combined with changes in struc-ture of microbial community in gut,it is speculated that this effect is closely related to the optimization of intes-tinal barrier and digestive function enhancement by the antibacterial peptides,chitin,and fermented products rich in the fermented BSFL paste.[Conclusions]The new generation fermented BSFL paste can achieve the weight gain by selectively enriching the gut microbiota(e.g.Firmicutes,Lactobacillus)in piglets and optimiz-ing the homeostasis of immune.It will provide key technological support for the green farming of animal hus-bandry.关键词
