The effects of plant extracts on lipid metabolism of chickens-A review

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.

Automated summary

Fat deposition is a crucial factor affecting chicken meat quality, which is closely associated with the lipid metabolism of chickens. Therefore, regulating the lipid metabolism is essential for improving the quality of chicken meat. Plant extracts have been widely used in chicken breeding due to their unique regulatory effects on growth and health. Certain plant extracts have been reported to alter fatty acid composition, decrease abdominal fat percentage, and enhance intramuscular fat content in chickens by improving antioxidant capacity, regulating gene expression, enzymes, and signaling pathways related to lipid metabolism, modulating intestinal microbiota, affecting hormone levels, and regulating DNA methylation. This review paper provides insights into the application and mechanisms of plant extracts in regulating the lipid metabolism of chickens, serving as a reference for future utilization of plant extracts in chicken breeding.
