Abstract

Shedrach Pewan used targeted sequencing of lipogenic genes in Tattykeel Australian white lambs for improving meat quality. He unraveled the underpinning molecular mechanisms for fat melting point, healthy omega-3s and marbling. Meat sheep producers can use these DNA marker-assisted selection tools for improving feed efficiency, commercial cuts, and healthy lamb.
