桑枝叶的营养特性及其在家禽生产中的应用研究进展OA

As a high-nutrient-density non-grain feed resource,mulberry branches and leaves is rich in high-quality protein,balanced amino acids,unsaturated fatty acids,and abundant minerals and vitamins.Its bioactive components-such as flavonoids,polysaccharides,and alkaloids-exert antioxidant,anti-inflammatory,and hypoglycemic functions by modulating signaling pathways like NF-κB and Nrf2,effec-tively improving poultry metabolic health.Moderate supplementation of mulberry branches and leaves in poultry diets enhances meat quality,optimizes yolk color and fatty acid profiles in eggs,and reduces lipid levels in waterfowl.However,excessive use may inhibit growth or lower egg production rates.Current appli-cations of mulberry branches and leaves are constrained by anti-nutritional factors and palatability limita-tions.Future research should focus on precision supplementation models,optimization of enzymatic hydroly-sis and fermentation processes,and interdisciplinary technology integration to advance the industrialization of mulberry branches and leaves-based feeds and promote sustainable livestock development.
