Feed used for culturing freshwater shrimp and preparation method

Abstract

The invention discloses a feed used for culturing freshwater shrimp and a preparation method, which comprises a main material and an auxiliary material, the component of the main material comprises the following ingredients by weight: 22-26 parts of fish flesh mash, 23-25 parts of fish meal, 8-12 parts of animal bone powder, 8-12 parts of blood powder, 10-14 parts of yeast powder, 4-6 parts of sunflower seed cake, 1-3 parts of bagasse powder, 8-12 parts of silkworm chrysalis, 0.8-1.2 parts of fish oil, 6-8 parts of soybean phosphatide, 2-4 parts of squid paste, 0.2-0.4 part of calcium dihydrogen phosphate, 0.1-0.2 part of green tea powder and 1-2 parts of black soya bean meal; the component of the auxiliary materials comprises the following ingredients by weight: 0.02-0.04 part of insect chitin, 0.01-0.03 part of vitamin premix, 0.05-0.07 part of epimeddium, 0.02-0.04 part of radix astragali, 0.02-0.04 part of medicated leaven and 0.02-0.04 part of tabasheer powder. The preparation method is characterized in that the main material can be mixed into a granular state, then the soup of the auxiliary materials is sprayed on the main material granules, and dried to obtain the product. The feed used for culturing freshwater shrimp is capable of promoting the full absorption of nutrition on the shrimps, preventing the generation of shrimp diseases, promoting the growth of the shrimp chitin and the efficacy of shelling, increasing the yield and reducing the feed coefficient.

Description

[0001] technical field [0002] The invention relates to the field of shrimp and crab feed, in particular to a feed for freshwater shrimp cultivation. Background technique [0003] With the development of the economy and the progress of the society, people's living standards are getting higher and higher, the diet is becoming more and more scientific, the demand for aquatic products is increasing, and there are more and more aquatic products. Among them, the cultivation of shrimp The amount is increasing, and the demand for feed is also increasing. The shrimp and crab feed sold on the market are not very targeted, and the shrimp is difficult to absorb, and often can only be partially absorbed, resulting in low feed utilization and polluting water sources. , Increase the disease rate of shrimp, reduce the growth rate, and increase the cost of feeding. When the feed of the present invention is fed to shrimps, the nutrients are easily absorbed by the shrimps, and at the same t...
