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

Embodiment 1

[0018] A feed additive for protecting the intestinal health of hybrid snakeheads, comprising the following ingredients: 25kg of copper-loaded montmorillonite, 25kg of mannan oligosaccharides, 18kg of Bacillus licheniformis, 12kg of glutamine dipeptide, 5kg of yeast nucleic acid, and 9kg of tributyrin And oregano essential oil 6kg.

[0019] The preparation method of the above-mentioned feed additive for protecting the intestinal health of hybrid snakeheads is to pulverize 25kg of copper-loaded montmorillonite, 25kg of mannan oligosaccharides, 18kg of Bacillus licheniformis, 12kg of glutamine dipeptide and 5kg of yeast nucleic acid respectively, and after pulverization, each The raw materials are passed through a 120-mesh sieve, and the crushed and sieved raw materials are uniformly mixed with 9 kg of tributyrin and 6 kg of oregano essential oil, so that the coefficient of variation of the mixed mixture is ≤ 5%, and the formula for protecting the intestinal health of hybrid snake...

Embodiment 2

[0022] A feed additive for protecting the intestinal health of hybrid snakeheads, comprising the following ingredients: 35kg of copper-loaded montmorillonite, 20kg of mannan oligosaccharides, 15kg of Bacillus licheniformis, 10kg of glutamine dipeptide, 6kg of yeast nucleic acid, and 10kg of tributyrin And oregano essential oil 5kg.

[0023] The preparation method of the above-mentioned feed additive for protecting the intestinal health of the hybrid snakehead includes pulverizing 35 kg of copper-loaded montmorillonite, 20 kg of mannan oligosaccharides, 15 kg of Bacillus licheniformis, 10 kg of glutamine dipeptide and 6 kg of yeast nucleic acid, and after pulverizing, each The raw materials are passed through a 140-mesh sieve, and the crushed and sieved raw materials are uniformly mixed with 10 kg of tributyrin and 5 kg of oregano essential oil, so that the coefficient of variation of the mixed mixture is ≤ 5%, and the formula for protecting the intestinal health of hybrid snake...

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...
