Environmentally friendly soft pellet feed for breeding freshwater salmon, and preparation method and use thereof

Abstract

The present invention discloses an environmentally friendly soft pellet feed for breeding freshwater salmon. The environmentally friendly soft pellet feed consists of the following components in parts by weight: 30-35 parts of fishmeal, 15-25 parts of soybean meal, 8-16 parts of peanut meal, 5-15 parts of fish oil, 5-13 parts of wheat middling, 7-13 parts of alfalfa powder, 3-8 parts of yeast powder, 0.01-0.1 part of gibberellin, 1-3 parts of phospholipids, 1-5 parts of rapeseed meal, 0.1-0.8 part of a multiple vitamin premix and 0.1-0.8 part of a multiple mineral premix. The soft pellet feed can obviously enhance the immunity ability of the freshwater salmon, uses mutual compensation and multi-party mediation of each of the components, can effectively improve the meat quality and nutritional value of the freshwater salmon, promotes the growth of fish, reduces the production cycles, and at the same time purifies and improves water quality. At the same time, decomposition of excessive feed is promoted. The soft pellet feed does not cause secondary water pollution, avoids mortality of the freshwater salmon caused by the secondary pollution of water body, and at the same time reduces the cost of purifying breeding water. Amino-oligosaccharin promotes digestion of freshwater salmon, the purpose of frequent food intake is avoided, and the incidence of excessive feed is avoided.

Description

technical field [0001] The invention relates to an environment-friendly soft pellet feed used in freshwater salmon cultivation, in particular to an environment-friendly soft pellet feed for freshwater salmon cultivation and its preparation method and application. Background technique [0002] Salmon, commonly known as salmon, is one of the world's famous economic fish. Salmon contains a lot of high-quality protein and omega-3 series of unsaturated fatty acids, which help to reduce blood lipids. At the same time, DHA and EPA also play a role in the development of children's brain nerve cells and visual development. Therefore, eating a moderate amount of salmon is beneficial to the prevention of cardiovascular and cerebrovascular diseases of middle-aged and elderly people, as well as the development of children's intelligence and vision. It has high nutritional value and enjoys the reputation of "treasure in water". [0003] The soft pellet feed is manufactured locally at the ...

AI Technical Summary

Problems solved by technology

[0005] Generally, if the granular fish feed cannot be completely eaten by small fish in the water, a layer of jelly formed by sugar and starch and raw materials leaked from the hydrolyzed pellets will lead to increased pool purification costs and increased mortality of small fish. high

[0006] At present, there are no relevant reports on the preparation method and application of environmentally friendly soft pellet feed used in the freshwater salmon breeding process at home and abroad.
