发酵饲料对凡纳滨对虾幼虾生长性能和肠道细菌菌群的影响
Effects of fermented feed on the growth performance and intestinal bacterial flora of juvenile Litopenaeus vannamei
摘要
Abstract
To investigate the effect of probiotic fermented feed on the nursery performance of juvenile Litopenaeus van-namei,four experimental groups were established,fed with KB(basic feed),RS(feed fermented by Lactobacillus acidophilus),YB(feed fermented by Bacillus subtilis),and YR(feed fermented by compound probiotics),respec-tively.Juvenile Litopenaeus vannamei with uniform size(0.41±0.01)g were selected for a 32-day nursery test to evaluate the growth performance of the juvenile shrimp,and microbial composition in the aquaculture water and shrimp intestines.The results showed that the fermented feed groups significantly(p<0.05)increased the survival rate of the juvenile shrimp,and significantly(p<0.05)reduced the feed conversion ratio;in the aquaculture water of the fermented feed groups,the relative abundance of Xanthomonadales significantly(p<0.05)increased,while the relative abundances of Rhizobiales,Parvibaculales,and Vibrionales significantly(p<0.05)decreased.The re-sults of this study indicated that although fermented feeds exerted no significant effect on the overall microbial com-munity structure of aquaculture water,they reduced the relative abundance of Vibrionales,improved the survival rate of juvenile Litopenaeus vannamei,optimized the composition of their intestinal flora,and thereby enhanced feed utili-zation efficiency and growth rate.关键词
