Abstract excerpt

Improving feed efficiency and reducing enteric methane emissions are key priorities for enhancing the sustainability of ruminant production systems. This study examined the genetic architecture of dry matter intake (DMI), residual feed intake (RFI), methane emissions (MEs), and BW in Merino sheep using weighted single-step genome-wide association studies. Phenotypic records were collected from 1 247 Merino sheep...
