The fat deposition is an important factor affecting chicken meat quality, which is closely related to lipid metabolism of chickens. Therefore, it is important to regulate the lipid metabolism of chickens to improve the chicken meat quality. Plant extracts have special regulatory effects on animal's growth and health and have been widely used in chicken breeding. Some plant extracts have been reported to have functions of changing the fatty acid composition, reducing abdominal fat percentage, and enhancing the intramuscular fat content of chickens by improving the antioxidant capacity, regulating the expression of genes, enzymes, and signaling pathways related to lipid metabolism, modulating intestinal microbiota, affecting hormones level, and regulating DNA methylation. This paper reviewed the application and mechanism of plant extracts on regulating lipid metabolism of chickens to provide a reference for the further application of plant extracts in chicken breeding.
脂肪沉积是影响鸡肉品质的重要因素，它与鸡的脂质代谢密切相关。因此，调节鸡的脂质代谢以提高鸡肉品质具有重要意义。植物提取物对动物的生长和健康具有特殊的调节作用，并已广泛应用于养鸡业。据报道，一些植物提取物具有改变脂肪酸组成、降低腹脂率以及通过提高抗氧化能力、调节与脂质代谢相关的基因、酶和信号通路的表达、调节肠道微生物群、影响激素水平和调节DNA甲基化来提高鸡的肌内脂肪含量的功能。本文综述了植物提取物在调节鸡脂质代谢方面的应用及作用机制，为植物提取物在养鸡业中的进一步应用提供参考。
