Problems solved by technology

[0002] At present, the price of fishmeal remains high, coupled with the lack of natural resources for producing fishmeal and the pressure of the water environment, the use of fishmeal in feed will be greatly restricted in the future, but the current feed relies heavily on fishmeal, resulting in higher feed costs. The higher the cost of farming, the higher the cost of farming, and the decline in farming profits. In order to better reduce the cost of farming without affecting the feed effect, it is imperative to study alternatives to fish meal, reduce the dependence of feed on fish meal, reduce the amount of fish meal used, and reduce The fishing of fish resources, thereby reducing the damage to the water environment

Abstract

The invention discloses a preparation method of fish meal-free soybean protein peptide feed for neritic fish and belongs to the technical field of feed preparation. The feed preparation method includes activated culture, solid-state fermentation of soybean meal, feed preparation and spray. The feed has a formula comprising the following components: corn flour, sesame paste residues, wheat bran, buckwheat husks, peanut vines, yam flour, fermented pork rib powder, salt, vegetable oil, white spirit with 52 DEG, extraction liquid of kaempferia galamga and clove, and water. The feed prepared through the method provided by the invention can promote the growth of the neritic fish and enhance the immunity of the neritic fish, facilitates digestion and absorption, can increase the survival rate ofthe neritic fish, does not contain fish meal, and has low cost, few anti-nutritional factors, high anti-oxidant capacity and a low residual rate in a water body.

Description

technical field [0001] The invention belongs to the technical field of feed preparation, and in particular relates to a preparation method of fishmeal-free shallow sea fish soybean protein peptide feed. Background technique [0002] At present, the price of fishmeal remains high, coupled with the lack of natural resources for producing fishmeal and the pressure of the water environment, the use of fishmeal in feed will be greatly restricted in the future, but the current feed relies heavily on fishmeal, resulting in higher feed costs. The higher the cost of farming, the higher the cost of farming, and the decline in farming profits. In order to better reduce the cost of farming without affecting the feed effect, it is imperative to study alternatives to fish meal, reduce the dependence of feed on fish meal, reduce the amount of fish meal used, and reduce The fishing of fish resources, thereby reducing the damage to the water environment.
