Compound feed capable of improving intestinal tract health of channel catfish and preparation method of compound feed

Abstract

The invention provides compound feed capable of improving intestinal tract health of channel catfish. The compound feed is prepared by mixing and drying a Chinese herbal extract and a basic component, wherein the weight ratio of the basic component to the Chinese herbal extract is (995-998): (2-5); each 2-5kg of Chinese herbal extract is prepared from the following Chinese herbal components through water extraction: 5-15g of pseudoginseng, 10-25g of dandelion, 10-30g of astragalus membranaceus, 10-25g of coptis chinensis, 10-30g of liquorice, 10-25g of perila seed, 10-30g of rheum officinale and 20-50g of garlic. The compound feed can improve health of the intestinal tract and a liver tissue, improve the intestinal immune function, maintain the stability of intestinal flora and prevent intussusception of the channel catfish; meanwhile, the invention further provides the compound feed prepared by the preparation method. The invention relates to the technical field of aquatic feed.

Description

technical field [0001] The invention relates to the technical field of aquatic feed, in particular to a compound feed capable of improving intestinal health of channel catfish and a preparation method thereof. Background technique [0002] With the intensive development of aquaculture, the scale of channel catfish farming has continued to expand, and the breeding density and production have continued to increase. However, with the expansion of the breeding scale, the increase of the stocking density, the deterioration of the breeding environment, excessive feeding and the use of low-quality feed, the intestinal and liver diseases of channel catfish are becoming more and more serious. one of the important factors. [0003] The intestine of fish is not only an important organ for digestion and absorption of nutrients, but also the largest immune defense, endocrine and metabolic organ in the body. Intestinal damage often causes damage to the hepatopancreas and other organs in...

AI Technical Summary

Problems solved by technology

[0004] Therefore, in order to solve the problems of low immunity and disease resistance, the harm of intestinal and liver diseases, and drug residues caused by antibiotic abuse in the current channel catfish breeding process, it is urgent to develop a method that can promote the healthy growth of channel catfish and improve feed utilization. It is of great significance for the healthy breeding and sustainable development of channel catfish
