Bile acid promotes fat metabolism, repair hepatic gallbladder damage, prevent tilapia fat liver disease – Aquatic Forum – China Animal Husbandry Website – A useful animal husbandry website

Robei fish fat liver a large deposition of fat in the fish liver and the fertilizer of the liver are essential. Currently due to the low price of the tilapia market, the feed is mostly high fat, high-sugar feed, and there is more cheap low feed materials, and long-term feeding high energy, high-fat and low-quality feed can cause Luo Non-fish liver metabolic load, liver fat abnormal deposition caused fatty liver disease, severe or even abundant metabolism, poor anti-stress capacity and high mortality. Although fatty liver disease is not infectious, fatty liver disease is often large and comprehensive, so its hazard and consequences far exceed infectious diseases. The harm of tilapia fatty liver disease can summarize the following four points: 1, reduce the growth performance of tilapia, lead to the slow growth of the fish and the increase in the bait coefficient, increase the cost of breeding, 2, reduce the immunity of Luo Nifish and stress resistant Sex, increase the incidence of disease and mortality; 3, reduce the sensory quality of Luo Nifish products, affect economic benefits; 4, indirectly lead to abuse of drugs such as antibiotics, affect food safety. Current clinical and production often use anti-fatty liver active factors to increase the absorption utilization of tilapia to lipids in the feed, reducing lipophilic content, and raising the growth performance of tilapia in the prevention of fatty liver disease. Reduce the bait coefficient, improve the purpose of survival and economic benefits. Bile acid has significant effects in promoting fat metabolism, which can effectively prevent the occurrence of tilapia fatty liver disease. Bile acid is the main component of bile, synthesized from liver, has strong surface activity, reinforcing pancreatic lipase activity, reduces fat surface tension, and promotes fat emulsification in the body through the intestinal liver cycle, promotes fat and Digestity and absorption of fat-soluble vitamins is the main pathway of liver to remove cholesterol. At the same time, bile acid can promote liver cell secretion bile, eliminate bile sludge, and take the harmful substances in the body, inhibit the absorption of intestinal toxins, maintain the health of the liver, and can increase the role of liver gaosphere. In addition, bile acid can also significantly increase the activity of serum alkaline phosphatase (Alp), significantly reduce the activity of alanine aminotransferase (Alt) and aspartate aminase (AST), indicating that bile acid has good anti-liver Damage and repair of liver injury. Zheng Zonglin et al. (2009)Enzyme activity. Yan Shaowei et al. (2015) pointed out that the feed was added to the feed to add 300 mg / kg bile acid to significantly increase the growth performance of Giwi Robei fish and increased intestinal fatty enzyme and protease activity. Many studies at home and abroad have proved the significant effects of bile acids in promoting fish fat metabolism: adding appropriate amount of bile acid in feed can significantly improve the yellow-tiled squid, rainbow trout, squid, ie silver bubble, speckled, grass fish, military cassa, The growth rate and weight gain rate of Daxumi increased the conversion rate of feed, and the bait coefficient was reduced. Adding bile acids in feed increases the contrast of mosaic and military cobi muscles or whole fish, and has a conservation in proteins. Promote lipid absorption, reducing military cao fish, tall grease and liver sediment. Add bile acids in feed, increased Japanese martial arts, dental, and tallsene fat alleled enzyme (lipoprotein esterase, hepatic lipase and total fatty enzyme) and fat enzyme activity, reduce total cholesterol, high-density lipoprotein cholesterol in grassfish serum Low density lipoprotein cholesterol and triglyceride have a significant effect on fat metabolism. In summary, adding bile acids in tilapia feed can promote fat metabolism of California, reduce liver burden, enhance liver function, repair liver damage, and prevent fatty liver disease.
