Abstract excerpt
BACKGROUND: Feed constitutes the largest cost in pig farming. However, the genetic mechanisms underlying feeding behavior (FB) and feed efficiency (FE), as well as their relationships, remain poorly understood. This study aims to: (1) identify genetic variants associated with FB, FE, and production traits, while improving genomic prediction (GP) accuracy; (2) investigate the relationships between FB, FE, and...
