Eggs are recognized for their rich nutrient profile, providing essential proteins and lipids with notable functional properties. This study examines the effects of incorporating Water Extract of Ampelopsis grossedentata (WEA) into poultry feed on egg quality, focusing on lipid content, choline, L-carnitine levels, and flavonoid compound deposition. Our results show significant increases in essential amino acids, flavonoids, and other bioactive compounds in eggs from WEA-treated hens, suggesting enhanced cardiovascular, antioxidant, and anti-inflammatory benefits. Additionally, we observed elevated levels of choline and betaine in egg yolks, alongside increased L-carnitine content, which may contribute to improved lipid metabolism and reduced cardiovascular disease risk. KEGG pathway analysis revealed upregulation of metabolites involved in critical metabolic pathways, enhancing the nutritional profile of eggs. Flavonoid compounds, traditionally associated with plant-based foods, were also significantly increased, with notable levels of 7, 4'-dihydroxyflavone, daidzein, and glycitein identified in WEA-treated eggs, indicating potential health benefits. These findings suggest that WEA supplementation can produce functional eggs with improved nutritional quality, offering a novel approach to enhancing egg production and meeting the growing demand for functional foods. Further research is needed to fully understand the bioavailability and health impacts of these enriched compounds.
鸡蛋因其丰富的营养成分而备受认可，提供了具有显著功能特性的必需蛋白质和脂质。本研究探讨了将显齿蛇葡萄水提物（WEA）纳入家禽饲料对鸡蛋质量的影响，重点关注脂质含量、胆碱、L-肉碱水平和类黄酮化合物沉积。我们的研究结果表明，WEA 处理母鸡所产鸡蛋中的必需氨基酸、类黄酮和其他生物活性化合物显著增加，提示其具有增强心血管、抗氧化和抗炎的益处。此外，我们还观察到蛋黄中胆碱和甜菜碱水平升高，同时 L-肉碱含量增加，这可能有助于改善脂质代谢，降低心血管疾病风险。KEGG 途径分析显示，关键代谢途径中的代谢物上调，增强了鸡蛋的营养谱。类黄酮化合物传统上与植物性食物相关，在 WEA 处理的鸡蛋中也显著增加，鉴定出 7、4'-二羟基黄酮、大豆苷元和黄豆苷元的含量较高，表明可能具有健康益处。这些发现表明，WEA 补充剂可以生产具有改善营养质量的功能性鸡蛋，为提高鸡蛋产量和满足对功能性食品的日益增长的需求提供了一种新方法。需要进一步研究以充分了解这些富集化合物的生物利用度和健康影响。
