Gut metagenomic analysis reveals prominent roles of Lactobacillus and cecal microbiota in chicken feed efficiency
Interactions between the host and gut microbiota can affect gut metabolism. In this study, the
individual performances of 252 hens were recorded to evaluate feed efficiency. Hens with …
