Abstract

The invention discloses a micro-granular feed for larva fish of bostrichthys sinensis. The micro-granular feed comprises the following components in parts by weight: 50-70 parts of animal nutritional ingredients, 15-25 parts of plant nutritional ingredients, 10-25 parts of functional ingredients, 0.5-2 parts of special vitamins, 0.5-2 parts of special trace elements, 0.5-1.5 parts of casein hydrolysate and 0.5-1.5 parts of lysine. A preparation method comprises the following steps: (1) manufacturing raw materials; (2) synthesizing a biological material; (3) converting to a cooked material; (4) puffing and granulating; (5) drying; (6) spraying and coating; and (7) performing vacuum drying. The feed disclosed by the invention adopts scientific matching and an advanced processing technology is used for assistance, so that the digestion and absorption rate of the feed is effectively improved, the growth of the larva fish of bostrichthys sinensis can be effectively promoted, and the occurrence of diseases during cultivation is reduced.

Description

technical field [0001] The invention relates to the technical field of aquatic feed, in particular to microparticle feed for larvae and juveniles of Chinese snakehead and a preparation method thereof. Background technique [0002] Chinese snakehead is a relatively high-end edible fish common in my country. It has the characteristics of less bone spurs and high meat yield. It is a high-protein and nutritious edible freshwater fish. In our country, it is often used as a nourishing high-grade fish for nourishing after surgery. According to medicinal records, Chinese snakehead has the effect of promoting muscle growth, enriching blood and promoting wound healing after cooking. [0003] Chinese snakehead is a typical ferocious carnivorous fish. It mainly feeds on small fish, shrimps, frogs and tadpoles, aquatic insects and other aquatic animals. It is worth noting that as the fish grows up, when the food is insufficient or the size When there is a huge difference, Chinese snakeh...
