Feed additive for protecting intestinal health of hybrid snakehead fish and preparation method of feed additive

Abstract

The invention discloses a feed additive for protecting intestinal health of a hybrid snakehead fish and a preparation method of the feed additive. The feed additive comprises the following components, by weight part: 25-35 parts of copper-loading montmorillonite, 20-30 parts of mannan oligosaccharide, 15-20 parts of bacillus licheniformis, 10-15 parts of glutamine dipeptide, 7-12 parts of tributyrin, 5-10 parts of origanum vulgare essential oil, and 4-8 parts of yeast nucleic acid. The method comprises: pulverizing the solid raw materials above, sieving the obtained materials through a sieve with 120-140 mesh, mixing the obtained materials with tributyrin and origanum vulgare essential oil to enable a coefficient of variation of the obtained mixture to be no more than 5%, and obtaining the feed additive. The feed additive can promote intestinal growth and development of the hybrid snakehead fish, ensures a normal intestinal structure and function, and optimizes intestinal flora of the hybrid snakehead fish. A normal intestinal micro-ecological environment is ensured, and the ability of digesting and absorbing nutritive substances of the hybrid snakehead fish is improved.

Description

technical field [0001] The invention belongs to the technical field of animal feed additives, and in particular relates to a feed additive for protecting the intestinal health of hybrid snakeheads and a preparation method thereof. Background technique [0002] Intestinal health is an important guarantee for the health of the body, and it is the main place for fish to digest and absorb nutrients; at the same time, the intestine is also the largest mucosal immune organ and the weakest immune barrier of fish, and it is the first line of defense for the body against foreign substances . Therefore, intestinal health is the key to healthy fish farming. The intestinal tract is usually one of the main routes of fish disease infection; the decline in intestinal health not only leads to a decline in the health of the body, but also reduces the rate of digestion and absorption of nutrients, and a large amount of undigested nutrients Substances are discharged into the water body, cau...

Problems solved by technology

In recent years, due to the decline in the breeding benefits of hybrid snakeheads, a large number of plant protein sources in their feed have been used, resulting in oxidative damage and structural damage to the intestinal tract of hybrid snakeheads; coupled with research on the nutritional physiology, artificial feed preparation technology, processing technology, and feeding technology of hybrid snakeheads The lack of data, and the current high-density intensive breeding model of hybrid snakeheads, and even mixed feeding of fresh trash fish, these factors will endanger or damage the health of the hybrid snakehead intestines, which in turn will affect their growth and development, and restrict the sustainable and healthy development of their industry
