Compound feed for female parent fishes of sturgeons

Abstract

The invention discloses a compound feed for female parent fishes of sturgeons. The compound feed is prepared in the following craft processes of: preparing raw material components into a mixture according to a processing method of a powdered feed, adjusting water and fish oil, and carrying out extrusion and pelleting. The powdered mixture comprises the following raw material components: degreased fish meal, alpha-starch, extruded soybeans, extruded corns, oligopeptide bean pulp, oligopeptide soluble fish meal, feather peptide powder, beer yeast, mineral substances, multivitamins for the fish, choline chloride, monocalcium phosphate and the like. Compared with the other sturgeon feeds, the compound feed disclosed by the invention has the advantages that the content of oligopeptide protein is remarkably increased, the use level of the fish meal is obviously reduced, not only is the culturing cost lowered, and the baiting performance and the nutrition characteristic can be improved as well. With the adoption of the compound feed for the female parent fishes of the sturgeons, the nutrition state of a female parent fish population of the sturgeons can be greatly improved, the maturing of sexual glands of the female parent fishes are promoted, and the reproductive performances such as the egg laying amount and the quality of ova are improved.

Description

technical field [0001] The invention relates to the field of aquatic product compound feed, in particular to the field of powdered compound feed for eel. Background technique [0002] With the rapid development of the aquaculture industry, the demand for fishmeal, which is the main protein source of aquafeed, is constantly increasing, resulting in tight supply and demand, and the price is rising year by year. To solve this contradiction, in addition to increasing the development and utilization of new protein resources, it is also very important to rationally utilize protein resources, realize further balanced preparation of diets, improve the utilization rate of existing protein raw materials, and reduce blind waste. [0003] In the 1990s, my country began large-scale breeding and breeding of sturgeons, and the breeding industry developed rapidly. At present, my country has become the world's largest country for raising sturgeons. The rapid development of the sturgeon aqua...

Problems solved by technology

[0004] The physiological characteristics of fish are that the digestive tract is short, and the food stays in the digestive tract for a limited time. It is difficult for the nutrients in the food to be completely absorbed by the body in a short period of time. environment, and is highly susceptible to disease
