vitamin B2
Vitamin B4 choline in fish has the following aspects:
To promote growth and improve feed utilization, promote growth, choline is indispensable nutrient elements in aquatic animal bait, can promote the growth of fish. For example, in the experiment of grass carp adult fish, adding 0.4% and 0.6% choline chloride can significantly improve the body weight gain rate and specific growth rate of fish. ,
Improve the utilization rate of feed: add choline can improve feed utilization, reduce feed coefficient. As for the above-mentioned grass carp adult fish experiment, the feed coefficient of the groups supplemented with 0.4% and 0.6% choline chloride was significantly reduced. Regulate fat metabolism, reduce fat accumulation, choline in the liver fat plays an important role in transportation and use, can reduce the accumulation of body fat fish. The addition of choline in the high-fat diet can improve the growth performance of fish and reduce the accumulation of body fat. The fat content of hepatopancreas and whole fish of grass carp was significantly reduced by 0.2%-0.6% choline chloride. ,
Improving fat metabolism enzyme activity: adding 0.2% to 0.6% before the choline chloride can significantly improve the grass carp intestinal lipase activity, add 0.6% choline chloride significantly improve the activity of lipoprotein lipase, adding 0.4% 0.6% choline chloride can significantly increase total lipase and hepatic lipase activity. Optimization of liver function, Promote glycogen utilization: to optimize the liver glycogen utilization, reduce serum cholesterol. ,
To prevent the fatty liver disease: vitamin, choline is essential for most fish is choline glycerol phosphate and one of the ingredients of choline phospholipids, can effectively adjust the intensity of fish body metabolism and fat deposition, prevent the occurrence of fatty liver. Choline is a precursor of the neurotransmitter acetylcholine, which can participate in the transmethylation reaction in vivo as a methyl donor and participate in the transmission of pheromones in the nervous system of organisms.

vitamin B2
There are many important role for vitamin B2 to fish, specific as follows:
promote the growth and development:
vitamin B2 in fish protein, fat and carbohydrate metabolism, helps the body protein synthesis, to ensure the growth and development of fish itself. Experiments have shown that adequate intake can promote fish growth. ,
Enhance immunity, can improve the fish immune system function, enhance its ability to resist disease, reduce mortality due to illness. If there is a lack of vitamin B2, fish are prone to problems such as decreased immunity. ,
Promoting digestion, feeding and has certain food calling function, can stimulate the appetite of the fish, increase their food intake. At the same time, it can also promote the digestion of fish, speed up the digestion and discharge of food in the gastrointestinal tract, and improve the utilization rate of feed. ,
Repair wounds: the fish’s gills and scales have significant anti-inflammatory, such as wound healing effect, help the fish surface damage repair.
Participate in antioxidant defense: participate in fish antioxidant defense system, improve the fish’s ability to adapt to the environment, help to reduce adverse environmental factors on the fish stress damage.
