Effect of Roughage Source on the Composition and Colonization of Rumen Bacteria and Methanogens in Dumont and Mongolian Sheep

Simple Summary The rumen microbial community plays a critical role in the production efficiency of ruminants and may be influenced by factors such as the animal breed and diet. We investigated the effects of breed (Dumont and Mongolian sheep) and roughage source (alfalfa hay and corn straw) on the rumen microbial community. We found that the roughage type strongly affects both the feed efficiency and rumen microbial community composition, and this effect was influenced by the interaction between the breed and roughage source. The two sheep breeds fed different roughages exhibited distinct rumen microbial communities, indicating that ruminal microbiota are simultaneously affected by diet and genetic differences, thereby altering the feed efficiency.
