Silkie chicken, an important chicken breed with high medicinal and nutritional value, has a long history of being used as a dietary supplement in China. However, the compounds with health-promoting effects in Silkie chickens remain unclear. In the present study, we conducted a comprehensive analysis of metabolic and lipidomic profiles to identify the characteristic bioactive compounds in Silkie chickens, using a common chicken breed as control. The results showed that the levels of 13 metabolites including estradiol, four lipid subclasses including cardiolipin (CL), eight lipid molecules, and three fatty acids including docosahexaenoic acid (C22:6) were significantly increased in Silkie chickens, which have physiological activities such as resisting chronic diseases and improving cognition. These characteristic bioactive compounds have effects on meat quality characteristics, including improving its water-holding capacity and umami taste and increasing the content of aromatic compounds and phenols. The differentially expressed genes (DEGs) between the two chicken breeds revealed the regulatory network for these characteristic bioactive compounds. Fifteen DEGs, including , are involved in the synthesis of characteristic metabolites. Eleven DEGs, including , were involved in the synthesis and transport of characteristic lipids and fatty acids. In summary, we identified characteristic bioactive compounds in Silkie chickens, and analyzed their effects on meat quality characteristics. This study provided important insight into Silkie chicken meat as a functional food.
丝羽乌骨鸡是一种具有很高药用和营养价值的重要鸡种,在中国作为膳食补充剂已有悠久的使用历史。然而,丝羽乌骨鸡中具有促进健康作用的化合物仍不明确。在本研究中,我们以一种常见鸡种作为对照,对丝羽乌骨鸡的代谢组和脂质组谱进行了全面分析,以鉴定其特征性生物活性化合物。结果表明,丝羽乌骨鸡中包括雌二醇在内的13种代谢物、包括心磷脂(CL)在内的4种脂质亚类、8种脂质分子以及包括二十二碳六烯酸(C22:6)在内的3种脂肪酸的水平显著升高,这些物质具有抵抗慢性疾病和改善认知等生理活性。这些特征性生物活性化合物对肉质特性有影响,包括提高其持水能力和鲜味,增加芳香族化合物和酚类的含量。两个鸡种之间的差异表达基因(DEGs)揭示了这些特征性生物活性化合物的调控网络。包括……在内的15个DEGs参与了特征性代谢物的合成。包括……在内的11个DEGs参与了特征性脂质和脂肪酸的合成与转运。总之,我们鉴定了丝羽乌骨鸡中的特征性生物活性化合物,并分析了它们对肉质特性的影响。本研究为丝羽乌骨鸡肉作为功能性食品提供了重要见解。
