The purpose of this study is to characterize and compare the gut microbes in six Chinese Holstein cows (CHC1, CHC2, CHC3, CHC4, CHC5, CHC6) under the same diet but different milk yields. High-throughput sequencing analysis was used to reveal and compare bacterial communities in faeces. The results showed 13 phyla in the six samples and the most dominant phylum was Firmicutes (approximately accounts for 71% OTUs), in which 18% OTUs were affiliated with Ruminococcaceae. Bacteroidetes was the subdominant phylum, which contributed to 17.5% of the total OTUs. While the majority of the bacterial genera found were unclassified, Solibacillus and Acinetbacter were the first and second predominant genera. Among the cases, the diversity and abundance of gut microbes in the Chinese Holstein cows have no significant difference under the same diet, which suggests that the relationship between milk ..
