| Summary: | Nonalcoholic fatty liver disease (NAFLD) and obesity are nutritional metabolic diseases that are prevalent in the poultry industry, and have a negative impact on its functioning. Veratric acid (VA) is a phenolic acid compound extracted from the Chinese herbal medicine Trollius chinensis Bunge, known for its anti-inflammatory and antioxidant properties. In this study, we used chicken hepatocytes (Leghorn male hepatoma cells) and treated with a mixture of oleic acid and palmitic acid as well as Yellow-feathered broilers fed a high-fat diet to examine the impact of VA on liver-lipid metabolism and deposition of abdominal fat. The results showed that VA (1μM) reduced the triglyceride and total cholesterol levels in the chicken hepatocytes (p < 0.05). In the broiler NAFLD model, VA significantly reduced liver TG levels (p < 0.05) without affecting growth performance. Dietary supplementation with 0.05% or 0.1% VA supplementation also significantly reduced the mRNA expression levels of key genes involved in the synthesis of fatty acids such as sterol regulatory element-binding protein 1c, fatty acid synthase, and acetyl-CoA carboxylase in broiler livers. In addition, 0.1% VA reduced abdominal fat accumulation and improved blood biochemical indexes in broilers. Network pharmacology analysis suggested that VA may participate in regulating fat metabolism in broilers via the proliferator-activated receptor signaling pathway. Taken together, the study results support VA as a candidate feed additive to provide a novel strategy for preventing NAFLD and excessive fat deposition in chickens. |
