Fermented soft pellet feed used for shrimp culture and production method of fermented soft pellet feed used for shrimp culture

Abstract

The invention discloses fermented soft pellet feed used for shrimp culture. The fermented soft pellet feed used for shrimp culture is obtained by fermenting feed raw materials with a zymophyte-enzymecompound preparation; and the feed raw materials comprise the following components in parts by weight: 3-15 parts of shrimp meal, 8-20 parts of fish meal, 10-30 parts of soybean meal, 3-15 parts of black soldier fly powder, 3-15 parts of shrimp shell powder, 3-15 parts of plasma proteins, 1-10 parts of silkworm chrysalis meal, 0-5 parts of water-soluble chitin, 1-10 parts of peanut meal, 5-20 parts of flour, 2-8 parts of potassium fulvate, 0-5 parts of fish oil, 0-5 parts of soybean oil, 0-5 parts of soybean phospholipid, 0.1-1.5 parts of calcium phosphate monobasic, 1-10 parts of a shrimp premix and 1-10 parts of a Chinese herbal medicine compound additive. According to the fermented feed, a method of pelleting before fermentation is adopted, nutrient substances of the raw materials are kept, and a digestive enzyme and active bacteria and fungi are added, so that the fermented soft pellet feed used for shrimp culture has the functions of significantly enhancing intestinal immunity ofshrimps and protecting livers and intestinal functions.

Description

technical field [0001] The invention belongs to the technical field of aquaculture feed, and relates to a feed for prawn farming, in particular to a fermented soft granular feed for prawn farming with bacteria-enzyme synergistic effect to protect the liver and intestines and a preparation method thereof. Background technique [0002] With the rapid development of my country's economy and the continuous improvement of people's living standards, people's demand for aquatic products and quality requirements are increasing day by day, the aquaculture industry has developed rapidly, and the breeding density of large-scale farms has increased to meet market demand. Because of its unique flavor and rich nutritional value, shrimp plays an important role in people's life and improves people's quality of life. However, with the sharp increase in scale and intensive farming of prawns, a large number of stress factors (such as nutrition, crowding, environmental changes, etc.) The resis...

AI Technical Summary

Problems solved by technology

[0005] Although there have been a lot of research reports on the nutritional requirements of prawns, the existing compound feeds still fail to meet the various nutrients needed for the growth of prawns. The traditional method of aquaculture prawns will use a large amount of powdered feed of plant raw materials, resulting in slow growth. , low breeding success rate, serious water pollution and low economic benefits, there is an urgent need to develop a new type of fermented feed for shrimp farming
