Summary
This study investigates the potential of garlic skin — a low-value by-product of garlic processing — as a dietary supplement for black goats, evaluating its influence on meat quality through metabolomics profiling. By characterising shifts in the meat metabolome, the authors likely identify bioactive compounds and metabolic pathways associated with improvements in flavour precursors, antioxidant status, and nutritional composition. The research contributes to the growing literature on agri-food by-product valorisation and functional livestock nutrition.
UK applicability
The study is conducted in a Chinese goat production context and is not directly transferable to UK livestock systems; however, the broader principle of using plant-derived by-products to enhance meat quality has relevance to UK producers exploring sustainable feed additives, particularly given UK interest in reducing synthetic inputs and improving meat nutrient density.
Key measures
Meat quality indices (e.g. pH, tenderness, colour, water-holding capacity); metabolite profiles via metabolomics; fatty acid composition; amino acid content
Outcomes reported
The study examined the effects of garlic skin inclusion in goat diets on meat quality parameters, using metabolomics analysis to identify changes in metabolite profiles associated with flavour, tenderness, and nutritional composition of black goat meat.
