Environment-friendly fish feed additive and preparation method thereof

Abstract

The invention discloses an environment-friendly fish feed additive and a preparation method thereof, and relates to the field of aquatic product culture. The additive is prepared from, by weight, 6-9 parts of rheum officinale, 10-20 parts of allicin, 10-15 parts of zanthoxylum ailanthus, 20-30 parts of bile acid, 16-20 parts of tartaric acid, 20-35 parts of sodium humate, 5-10 parts of liquorice, 5-8 parts of coptis chinensis, 7-12 parts of lacquer leaves and 22-28 parts of choline chloride. The tartaric acid and the sodium humate are added into the additive, the food intake frequency of fishes in muggy weather can be increased through the tartaric acid, the effect of increasing the appetite can be achieved, and the sodium humate can improve the gastrointestinal function, promote gastric secretion, increase the appetite, promote nutrient substances to enter a body more quickly, stimulate growth of beneficial bacteria in the stomach and intestine and inhibit the reproduction of spoilage bacteria. Due to the fact that the sodium humate can promote digestion and absorption, mineral elements in the feed formula can be better absorbed and utilized.

Description

technical field [0001] The invention relates to the field of aquatic product cultivation, in particular to an environmentally friendly fish feed additive and a preparation method thereof. Background technique [0002] Fish products have high nutritional value, which is very important for improving dietary structure and improving human health. With the increasing awareness of health, consumers have higher and higher consumption demand and quality requirements for fish products. Carp, grass carp, etc. my country's main freshwater aquaculture fish accounts for 33-40% of the total fish aquaculture output. [0003] Most of the existing fish feeds are high-protein and high-fat, and long-term intake of such food is likely to induce long-term accumulation of fat in the liver, forming fatty liver, destroying liver function, causing metabolic disorders, and causing hepatobiliary syndrome. At the same time, the fish's digestive tract is short and the emptying speed is fast. The nutrien...

Problems solved by technology

[0003] Most of the existing fish feeds are high-protein and high-fat, and long-term intake of such food is likely to induce long-term accumulation of fat in the liver, forming fatty liver, destroying liver function, causing metabolic disorders, and causing hepatobiliary syndrome. At the same time, the fish's digestive tract is short and the emptying speed is fast. The nutrients in the feed are excreted before they can be absorbed, which reduces the feed absorption rate. In addition, due to improper use of additives, the nitrogen and phosphorus in the fish discharge make the aquaculture The water body is seriously polluted, and the survival rate of breeding is not high. Secondly, in sultry weather, the appetite of the fish is obviously reduced, and it is difficult to eat and eat, which makes the growth rate of the fish slower
