Embodiment 1

[0019] The present invention prepares the method for freshwater fish feed with discarded crayfish shell, comprises the following steps:

[0020] (1) Prepare shrimp powder with discarded crayfish shells: first clean the shrimp shells, steam and sterilize them in a high-temperature steam pot at a temperature of 110-120°C, and the time for steaming and sterilizing them is 30 minutes, then treat them with acid, and dry them. The temperature is 50 ℃, drying for 10 hours, so that the moisture content of the shrimp shell is controlled below 5%, and the shrimp powder is obtained by crushing;

[0021] (2) Grind 20 parts of shrimp powder prepared above, 30 kg of grass powder, 20 kg of bean cake, 10 kg of rice bran, 5 kg of bran, 5 kg of Chinese medicine compound, 10 kg of corn flour, 1 kg of bone meal, and 1 kg of salt, and mix them uniformly; Materials: alfalfa powder: 2kg, dandelion powder: 2kg, Houttuynia cordata powder: 5kg, honeysuckle powder: 5kg, eucommia leaf powder: 2kg, mother...

Embodiment 2

[0026] The present invention prepares the method for freshwater fish feed with discarded crayfish shell, comprises the following steps:

[0027] (1) Prepare shrimp powder with discarded crayfish shells: first clean the shrimp shells, steam and sterilize them in a high-temperature steam pot at a temperature of 100-110°C, and the steaming and disinfection time is 45 minutes, then treat them with acid, and dry them. The temperature is 60°C, dried for 6 hours, so that the moisture content of the shrimp shell is controlled below 5%, and the shrimp powder is obtained by crushing;

[0028] (2) Shrimp powder prepared above: 30kg and grass powder 20kg, bean cake: 20kg, rice bran: 10kg, bran: 10kg, Chinese medicine compound: 2kg, corn flour: 5kg, bone meal: 2kg, salt: 0.5kg, pulverized , mixed evenly; Chinese medicine compound: alfalfa powder: 1kg, dandelion powder: 1kg, houttuynia cordata powder: 5kg, honeysuckle powder: 1kg, eucommia leaf powder: 5kg and motherwort powder: 5kg, pulver...

Embodiment 3

[0033] The present invention prepares the method for freshwater fish feed with discarded crayfish shell, comprises the following steps:

[0034] (1) Prepare shrimp powder with discarded crayfish shells: first clean the shrimp shells, steam and sterilize them in a high-temperature steam pot at a temperature of 100-110°C, and the steaming and disinfection time is 60 minutes, then treat them with acid, and dry them. The temperature is 70°C, dried for 5 hours, so that the moisture content of the shrimp shell is controlled below 5%, and the shrimp powder is obtained by crushing;

[0035] (2) Shrimp powder prepared above: 25kg and grass powder: 25kg, bean cake: 15kg, rice bran: 10kg, bran: 7kg, Chinese medicine compound: 3kg, corn flour: 6kg, bone meal: 1kg, salt: 1kg, pulverized , mixed evenly; Chinese medicine compound: alfalfa powder: 3kg, dandelion powder: 2kg, Houttuynia cordata powder: 3kg, honeysuckle powder: 2kg, eucommia leaf powder: 3kg, motherwort powder: 1kg, pulverize a...

Abstract

The invention discloses a method for preparing a freshwater fish feed from abandoned crawfish shells, wherein the method comprises the following steps: preparing a shrimp powder from the abandoned crawfish shells; crushing 20-30 parts of the prepared shrimp powder, 20-30 parts of grass meal, 10-20 parts of bean cakes, 10-20 parts of rice bran, 5-10 parts of bran, 2-5 parts of fish meal, 2-5 partsof a traditional Chinese medicine compound, 5-10 parts of corn flour, 1-2 parts of bone meal, and 0.5-1 part of table salt, and mixing evenly; sending the mixed material into a bulking machine, and carrying out bulking treatment; drying, and cooling; and granulating, and packaging. The feed has good effect of gaining weight, is a low-price freshwater fish feed, can turn the abandoned crawfish shells into treasure, and has extremely high economic and environmental benefits.

Description

technical field [0001] The invention belongs to the field of freshwater fish feed, in particular to a method for preparing freshwater fish feed from discarded crayfish shells. Background technique [0002] Protein is the core part of fish feed, and fish meal is the highest quality protein source in aquatic feed. The proportion of essential amino acids in crude protein is significantly higher than that of plant feed, reaching more than 50%. However, the current global shortage of fish meal has caused fish meal The price remains high, so that the preparation of feed is greatly restricted due to cost issues, and finding new alternative protein sources is the only way to prepare cheap feed. [0003] Crayfish are widely distributed in the middle and lower reaches of the Yangtze River in my country, including Jiangsu, Hubei, Hunan, Jiangxi, Zhejiang, Anhui, Shandong and other provinces. With the continuous increase of people's demand for crayfish and the increasing export volume ...
