Messenger RNA sequencing and pathway analysis provide novel insights into the biological basis of chickens’ feed efficiency

摘要

BackgroundAdvanced selection technologies have been developed and continually optimized to improve traits of agricultural importance; however, these methods have been primarily applied without knowledge of underlying biological changes that may be induced by selection. This study aims to characterize the biological basis of differences between chickens with low and high feed efficiency (FE) with a long-term goal of improving the ability to select for FE.
