Summary

This study employs transcriptomic analysis to investigate the molecular mechanisms underpinning differences in growth performance, meat quality, and fatty acid metabolism between Sunit lambs raised on pasture and those on concentrate-based diets. By identifying differentially expressed genes associated with lipid metabolism and muscle development, the research offers mechanistic insight into why feeding regime influences fatty acid profiles and overall meat quality. The findings may inform optimised feeding strategies that balance productive efficiency with desirable meat quality outcomes in lamb production.

UK applicability

The study focuses on the Sunit breed, a native Mongolian breed reared under Inner Mongolia conditions, so direct applicability to UK sheep breeds and farming contexts is limited. However, the underlying molecular findings on pasture versus concentrate feeding effects on fatty acid metabolism are broadly relevant to UK lamb producers and researchers interested in the nutritional and quality benefits of grass-based systems.

Key measures

Differentially expressed genes (RNA-seq); carcass traits; meat quality parameters (e.g. pH, tenderness, colour); fatty acid composition; muscle growth and development gene expression

Outcomes reported

The study measured carcass traits, meat quality parameters, and differentially expressed genes related to muscle growth, development, and fatty acid metabolism in Sunit lambs reared under pasture versus concentrate feeding systems. Gene expression profiling likely identified candidate genes and pathways explaining variation in fatty acid profiles and meat quality between the two rearing conditions.
