Relationship between rumen microbial community structure, function and feed efficiency in goats based on metagenomics and metabolomics
The rising costs of feed raw materials on a global scale have made the enhancement of feed efficiency and the reduction of production costs primary concerns within the livestock industry. Enhancing feed efficiency not only lowers production costs but also improves the quality of dairy products and decreases greenhouse gas emissions. This study aimed to investigate the differences in ruminal microbial composition, functional potential, and metabolic characteristics among goats exhibiting varying levels of feed efficiency, as indicated by residual feed intake (RFI).
