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

Abstract

The invention discloses a feed additive for improving fish liver health. The additive comprises the following ingredients in percentage by mass: fructus lycii 5-20%, radix astragali 10-20%, lonicera japonica 5-10%, kudzuvine roots 5-10%, magnolia vine fruits 10-15%, Chinese thorowax roots 2-15%, chitosan oligosaccharide 10-20%, alga polysaccharides 10-20% and the balance being stuffing. The feed additive for improving the fish liver health provided by the invention can be used as the additive for various kinds of fish feed and the addition amount of the additive in the feed is 0.05-0.3% of feed weight.

Description

technical field [0001] The invention relates to the technical field of feed additives, in particular to a feed additive for fish liver health and a preparation method thereof. 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 and ot...
