调查滇南小穗(DNSE)微生物群落的差异,大河黑(DHB)和约克郡(YS)猪,我们使用宏基因组方法比较了微生物分类和功能组成。共鉴定出1,002,362个非冗余微生物基因,DHB和YS猪与DNSE猪相比具有更相似的遗传组成。拟杆菌,Firmicutes和Spirochetes是所有猪品种中最丰富的三个门,DNSE猪的Prevotella属丰度高于DHB和YS猪。三个猪品种的功能特征各不相同,DNSE猪比其他两个猪品种具有更活跃的碳水化合物代谢和更丰富的抗生素抗性基因。此外,我们发现DNSE猪的肽和大环内酯抗性基因比DHB猪更丰富(p<0.05)。本研究将有助于为云南省地方猪品种的发展提供理论依据,中国。
To investigate the difference of microbial communities among Diannan small-ear (DNSE), Dahe black (DHB) and Yorkshire (YS) pigs, we compared the microbial taxonomic and functional composition using a metagenomic approach. A total of 1,002,362 non-redundant microbial genes were identified, DHB and YS pigs had more similar genetic makeup compared with DNSE pigs. Bacteroidetes, Firmicutes and Spirochetes were the three most abundant phyla for all pig breeds, and DNSE pigs had a higher abundance of Prevotella genus than DHB and YS pigs. The functional profiles varied among the three pig breeds, DNSE pigs had more active carbohydrate metabolism and more abundant antibiotic resistance genes than the other two pig breeds. Moreover, we found that peptide and macrolide resistances genes in DNSE pigs were more abundant than that in DHB pigs (p < 0.05). This study will help to provide a theoretical basis for the development of native pig breeds in Yunnan Province, China.
