By-products from winemaking, such as grape pomace, grape seeds, grape skins, or extracts made from them, represent a cost-effective and sustainable bioresource. These by-products are a source of polyphenolic compounds, plant fibers and-in the case of seeds-essential fatty acids with various health-promoting effects for livestock. Numerous studies involving fast-growing broiler breeds-which often suffer from metabolic inflammation and oxidative stress due to disproportionate breast muscle growth leading to issues like cardiorespiratory insufficiency-indicate that supplementing feed with grape by-products improves performance, particularly weight gain and feed efficiency. This literature review demonstrates that the performance-enhancing effects of grape by-products in fast-growing broiler breeds can be attributed to various mechanisms such as improved nutrient digestibility, a positive influence on intestinal morphology and integrity, the favorable modulation of the microbial community in the gut, the inhibition of oxidative stress or the enhancement of the antioxidant defense system, and the stimulation of the immune response.
葡萄酒酿造过程中的副产品，如葡萄皮渣、葡萄籽、葡萄皮或由它们制成的提取物，是一种经济高效且可持续的生物资源。这些副产品是多酚化合物、植物纤维的来源，对于种子而言，还是必需脂肪酸的来源，对牲畜具有多种促进健康的作用。许多针对快速生长的肉鸡品种的研究表明，在饲料中添加葡萄副产品可提高生产性能，尤其是体重增加和饲料效率。这些快速生长的肉鸡品种由于胸肌生长不均衡，常遭受代谢性炎症和氧化应激，进而导致心肺功能不全等问题。这篇文献综述表明，葡萄副产品对快速生长的肉鸡品种的性能提升作用可归因于多种机制，如提高养分消化率、对肠道形态和完整性产生积极影响、对肠道微生物群落进行有利调节、抑制氧化应激或增强抗氧化防御系统，以及刺激免疫反应。
