Functional feed additive for protecting livers of cultured fishes and using method thereof

Abstract

The invention provides a functional feed additive for protecting livers of cultured fishes and a using method thereof. Each 1000g of the additive comprises the following components: 80 to 120 g of curcumin, 120 to 180 g of 98% betaine hydrochloride, 80 to 120 g of taurine, 160 to 240 g of 80% bile acid, 30 to 80 g of silymarin, 60 to 140 g of liquorice extract and 250 to 340 g of mirabilite. The additive can quickly repair liver cells, promote bile secretion, reduce liver fat accumulation, rapidly activate body immunity and quickly return the body metabolism to normal running, can effectivelydegrade various mycotoxins in feeds and water body drug residues and relieve metabolism problems that ammonia nitrogen and nitrous acid penetrate the body as the water body worsens, can effectively scavenge free radicals, reduce damage to liver and hepatopancreas and increase the survival rate of fries and juvenile shrimps and crabs, and has significant effect on hepatopancreas swelling, hepatatrophia, red liver, yellow liver and mottled liver of shrimps and crabs.

Description

technical field [0001] The invention relates to the technical field of feed additives, in particular to a functional feed additive for liver and liver protection of cultured fish. Background technique [0002] Fatty liver disease in farmed fish is a widespread disease that has plagued the aquaculture industry for many years. Although it has been researched and prevented for many years, it has not been fundamentally curbed so far. Fish fatty liver, more precisely, is a collective term describing the physiological phenomenon characterized by excess hepatic lipid accumulation above the normal hepatic lipid content in fish and the associated metabolic diseases. Its hazards mainly include four aspects: ①Reduce growth performance and feed utilization efficiency, increase breeding costs; ②Reduce immunity and stress tolerance, increase sensitivity to diseases and mortality; ③Reduce sensory quality of products, affecting Product sales; ④Indirectly lead to the abuse of antibiotics an...

Problems solved by technology

Its hazards mainly include four aspects: ①Reduce growth performance and feed utilization efficiency, increase breeding costs; ②Reduce immunity and stress tolerance, increase sensitivity to diseases and mortality; ③Reduce sensory quality of products, affecting Product sales; ④Indirectly lead to the abuse of antibiotics and other drugs, affecting food safety

[0003] At present, in the field of fish liver protection products, there are some patents for liver protection products (such as: 201410359787.0 and 201110245640.5). The liver protection ingredients of this type of patent are mainly for the absorption and utilization of fat. However, when the liver metabolizes fat , will produce a lot of oxygen free radicals, excessive oxygen free radicals will increase the damage of liver cells, and then affect the liver's metabolism of fat

In addition, there are also some patents (such as: 201610136687.0), which consider adding Chinese herbal medicine to repair liver damage and prevent fatty liver, but the absorption of active ingredients in Chinese herbal medicine by fish is very low. In the production of feed or feed, the uniformity of mixing is relatively low
