Problems solved by technology
Farmers mostly use high-protein, high-energy full-price compound feed to increase the nutrient content of the feed. The excessive amount of fat in the feed will cause crayfish to incompletely digest and absorb the excessively high fat, resulting in a large amount of Fat accumulates in the liver and body of the shrimp, which makes the shrimp liver load heavier and seriously affects its liver function and normal growth; in addition, the vitamin content in the feed is too high, which will also cause vitaminmetabolism disorders in the crayfish liver

Embodiment 1
[0028] The preparation method of feed additive comprises the following steps:
[0029] 1) Calculate according to the parts by weight, weigh each raw material: 15 parts of knotweed, 25 parts of perilla, 10 parts of gardenia, 16 parts of paeonol, 8 parts of angelica, 5 parts of cloud vanilla, 4 parts of tangerine peel and 4 parts of earthworm, spare;
[0030] 2) Mix the raw materials except Earthworm, add water to cook, filter to obtain the filtrate and filter residue; put the filter residue into a beater and add an appropriate amount of water for beating treatment to obtain slurry I, and heat slurry I to 40 ° C, and then Cellulase is added for enzymolysis to obtain enzymatic solution I; the amount of cellulase added is 0.2% of the weight of slurry I.
[0031] 3) Put Dilong into a beater alone and add an appropriate amount of water for beating treatment to obtain slurry II, raise the temperature of slurry II to 40°C, and then add neutral protease for enzymolysis to obtain enzym...
Embodiment 2
[0034] A feed additive comprising the steps of:
[0035] 1) Calculate according to the parts by weight, weigh each raw material: 25 parts of knotweed, 15 parts of perilla, 20 parts of gardenia, 8 parts of paeonol, 16 parts of angelica, 10 parts of cloud vanilla, 8 parts of tangerine peel and 8 parts of earthworm, spare;
[0036] 2) Mix the raw materials except earthworm, add water to cook, filter to obtain filtrate and filter residue; put the filter residue into a beater and add an appropriate amount of water for beating treatment to obtain slurry I, and heat slurry I to 60 ° C, and then Cellulase is added for enzymolysis to obtain enzymatic solution I; the amount of cellulase added is 0.4% of the weight of slurry I.
[0037] 3) Put Dilong into a beater alone and add an appropriate amount of water for beating treatment to obtain slurry II, raise the temperature of slurry II to 50°C, and then add neutral protease for enzymolysis to obtain enzymatic solution II; neutral proteas...

Abstract
The invention provides a breeding feed of crayfish. The breeding feed comprises the following raw materials in parts by weight of 40-50 parts of corn powder, 4-8 parts of chicken meat powder, 20-30 parts of paddy rice powder, 10-20 parts of soybean meal, 10-20 parts of peanut meal, 15-25 parts of edible mushroom residues, 1-3 parts of soy lecithin, 4-8 parts of zeolite powder, 0.2-0.8 part of trace elements, and 0.5-1.5 parts of a feed additive, wherein the feed additive is mainly prepared through fermentation with polygonum cuspidatum, purple perilla, gardenia, tree peony root bark, angelicasinensis, cymbopogon distans, dried orange peel and earthworms through bacillus subtilis. The feed not only can promote the repair of chemical liver injury of the crayfish, improve the safety of liverfunctions, strengthen the constitutions of the crayfish, and increase the survival rate, and has the advantage of being good in palatability.
Description
technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a crayfish breeding feed. Background technique [0002] Freshwater crayfish are typical omnivores. It eats grass, aquatic plants, grain feed and animal feed. Feeding pure natural organic feeds such as artificially propagated aquatic organisms, small animals, and planted aquatic plants is better in palatability, rich in nutrition, fresh and delicious than purchased commercial feeds, and it is completely unnecessary to buy compound feeds. It can not only avoid harmful ingredients such as hormones in the commercial feed exceeding the standard, ensure that the commercial lobster is green and pollution-free, but also save a large amount of feed investment every year. [0003] The liver function of crayfish is to secrete digestive enzymes and absorb and store nutrients. At the same time, the liver of crayfish has the function of detoxification and defense; it can pro...
