Micro granular dite contg. Luchong for prawn, and its prepn. technique

Abstract

A bittern worm tablet as the feed of young prawn is prepared from powdered material, bittern worm pulp, fish paste, fish oil, minerals, vitamines, cholesterol, lecithin, chitosan, polymycose and spirulina through superfine pulverizing, proportionally mixing, colloid grinding, homogenizing and tabletting. Its advantages are high effect, low cost and no pollution to water.

Description

technical field [0001] The invention belongs to an artificially compounded microparticle feed for breeding aquatic animal larvae, and is a technology for preparing artemia shrimp chips that simulates the nutrition and properties of natural animal feed (artemia nauplii). Background technique [0002] Before the present invention was made, the larvae of aquatic animals were cultivated, and live artemia nauplii were first used as feed for feeding. Due to the unstable production of Artemia eggs and the high price in the early stage, researchers and aquaculture experts began to study substitutes (such as milk powder, egg yolk, soybean milk, etc.) to replace part of Artemia nauplii to cultivate aquatic animal larvae. By the eighties of the 20th century, began to study artificially compounding micro-particle feeds, there were bonded micro-particle baits, micro-particle encapsulated feeds, etc., which had better seedling raising effects than milk powder, egg yolk, etc. (survival rat...

Problems solved by technology

Due to the limitation of its raw material resources, the protein source of its shrimp chips is mainly fish and shrimp meat, which is far behind natural animal feed in terms of nutritional comprehensiveness and food attraction, and its water resistance is poor, and its stability is less than that of natural animal feed. 2 hours; the dissolution rate in water is as high as about 10%
