Breeding feed for larimichthys crocea fries and preparation method of breeding feed

Abstract

The invention belongs to the technical field of aquatic feed, and particularly relates to breeding feed for larimichthys crocea fries and a preparation method of the breeding feed. According to the invention, the puffed corn flour, the puffed soybean flour, the puffed tapioca flour and the puffed rice flour are added according to a specific proportion, so that the purposes that main nutritional ingredients in the feed are balanced and are easy to digest and absorb are achieved. According to the invention, a preheating type screw bulking machine is also utilized to carry out specific and sufficient bulking operation on the four crushed materials, so that the basic advantages of sterilization, food calling and easy absorption of the bulked powder are realized. The invention has the following advantages: 1, four kinds of puffed powder have basic advantages of high-temperature sterilization, good flavor, high food calling property, easy digestion and easy absorption of nutrient substances; secondly, four kinds of puffed powder are added according to a specific proportion, so that the proportion of main nutrient substances such as starch, grease, vitamins and protein is suitable for breeding the larimichthys crocea fries;

Description

technical field [0001] The invention belongs to the technical field of aquatic feed, and in particular relates to a breeding feed for large yellow croaker seedlings and a preparation method thereof. Background technique [0002] At the end of April or early May, after the large yellow croaker is released, it will go through a period of seedling stage. During this period, the feeding system for large yellow croaker juveniles mainly included frozen small fish and special feed for fry. [0003] For example, the Chinese invention patent with the patent publication number of 106465809A and the publication date of 2017.03.01 discloses a feed formula for carp seedlings, which includes the following components, and each component is prepared according to the following weight components: 5-15 parts of sugar beet, corn Bud powder 4-16 parts, seaweed powder 3-12 parts, cow dung 3-9 parts, pig manure 5-25 parts, sorghum 5-15 parts, locust powder 10-20 parts, Bupleurum 5-25 parts, dodde...

AI Technical Summary

Problems solved by technology

[0005] However, the corn flour and grain sprout powder are only simple pulverized materials, so they have at least the following deficiencies: 1. May contain pathogenic bacteria and viruses; 2. Relatively indigestible; 3. The absorption rate of various nutrients is not high

[0009] However, the heating structure of the twin-screw extruder in this utility model patent is relatively simple, the heating temperature cannot be increased, and the upper limit of the material temperature is relatively low. Inadequate and incomplete puffing
