Abstract

High throughput sequencing was used to examine the rumen microbiota of sika deer fed high (OLH) and low concentration (OLL) of tannin rich oak leaves. The results showed that Prevotella spp. were the most dominant bacteria. The most predominant methanogens were the members of the order Methanoplasmatales. The dominant rumen protozoa were Entodinium longinucleatum, Eudiplodinium maggii, and Epidinium caudatum, and the fungal communities were mostly represented by Piromyces spp. Moreover, the relative abundance of Pseudobutyrivibrio spp. (P=0.026), unidentified bacteria (P=0.028), and Prevotella spp. (P=0.022) was lower in the OLH group than in the OLL group. The concentration of propionate in the OLH group was greater than in the OLL group (P=0.006). Patterns of relationships showed that methanogens belonging to the order Methanoplasmatales were negatively correlated with Treponema spp., Ent. Longinucleatum, and acetate. Methanosphaera stadtmanae was positively correlated to propionate, while Methanobrevibacter ruminantium was negatively associated with Methanobrevibacter thaueri and Methanobrevibacter millerae. Tannins altered the rumen microbes and fermentation patterns. However, the response of the entire rumen microbiota and the relationship between rumen microorganisms and the fermentation parameters were not fully understood.
