Problems solved by technology

By consulting open literature and investigating various loach feeds sold in the market, we found that the protein content of loach artificial compound feeds currently on the market is generally low, and the nutritional content is unbalanced. It is not suitable for the cultivation of loach seedlings. Cultivation of adult loach
There is no report or sale of a full-price special compound feed suitable for the growth of loach juveniles and improving their survival rate

Abstract

The invention discloses a loach juvenile fish feed and a preparation method thereof, which is composed of a certain proportion of Peruvian fish meal, brewer's yeast, shrimp meal, soybean protein isolate, secondary meal, starch, fat, calcium dihydrogen phosphate and additives. The steps are: A. crushing all powder raw materials respectively; B. weighing raw materials according to the mass fraction of loach juveniles; C. mixing the weighed raw materials to obtain a mixture; D. weighing parts by weight of loach juveniles Weigh fish oil and soybean oil and mix to obtain fat; E, put the mixture of step C and the fat of step D into a blender and mix, and store at low temperature; F, before feeding, add an appropriate amount of water, stir evenly, and make feed. It has good palatability, high digestion and utilization rate, significantly improves the growth rate of loach larvae, enhances the body immunity of loach larvae, and improves its survival rate. Its source of raw materials is stable, the price is low, and the production process is simple, creating a huge economic price.

Description

Technical field [0001] The invention relates to the technical field of fish nutrition and feed, in particular to a special feed for loach larvae and juveniles, and also to a preparation method of a special feed for loach larvae and juveniles. The feed is suitable for loach seed 5-30 days after hatching. Background technique [0002] Loach contains high protein and low fat, the meat is fresh and tender, nutritious, delicious, rich in vitamins and minerals, and has high nutritional value. Loach also has high medicinal value. Its main function is to invigorate the spleen and qi, nourish yin and strengthen yang, clear away heat and detoxify, eliminate dampness, and relieve thirst. It is called "water ginseng".
