Embodiment 1

[0025] The preparation method of feed additive comprises the following steps:

[0026] 1) Calculate according to the parts by weight, weigh each raw material: 15 parts of astragalus, 25 parts of wolfberry, 10 parts of tea, 16 parts of Artemisia annua, 8 parts of angelica, 5 parts of cabbage, 4 parts of dendrobium and 4 parts of cicada, and set aside;

[0027] 2) Mix the raw materials except cicadas, 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 a slurry, heat the slurry to 40°C, and then add cellulose The enzymatic hydrolysis is carried out to obtain an enzymolysis solution; the added amount of cellulase is 0.2% of the weight of the slurry; the cicadas are crushed and processed to obtain cicada powder.

[0028] 3) Mix the filtrate, the enzymatic solution and the cicada powder to obtain a suspension, add a Bacillus subtilis medium to the suspension,...

Embodiment 2

[0032] A feed additive comprising the steps of:

[0033] 1) Calculate according to the parts by weight, weigh each raw material: 25 parts of astragalus, 15 parts of wolfberry, 20 parts of tea, 8 parts of Artemisia annua, 16 parts of angelica, 10 parts of cabbage, 8 parts of dendrobium and 8 parts of cicada, and set aside;

[0034] 2) Mix the raw materials except cicadas, 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 a slurry, heat the slurry to 60°C, and then add cellulose The enzymatic hydrolysis is carried out to obtain an enzymolysis solution; the added amount of cellulase is 0.4% of the weight of the slurry; the cicadas are crushed and processed to obtain cicada powder.

[0035] 3) The filtrate, the enzymatic solution and the cicada powder are mixed to obtain a suspension, and the Bacillus subtilis medium is added to the suspension, and then in...

Embodiment 3

[0039] A compound feed for promoting shelling of prawns, calculated in parts by weight, comprising the following raw materials:

[0040] 46 parts of corn flour, 6 parts of seaweed enzymolysis extract of Example 1, 24 parts of yeast extract, 16 parts of soybean meal, 14 parts of beer tank, 20 parts of earthworm powder, 2 parts of soybean lecithin, 1 part of bile acid, zeolite powder 6 parts, 0.6 part of manganese, zinc and iron and 1 part of the feed additive of embodiment 1.

Abstract

The invention provides a compound feed capable of promoting shelling of prawns. The compound feed comprises the following raw materials in parts by weight: 40-50 parts of maize flour, 4-8 parts of seaweed enzymolysis extracts, 20-30 parts of yeast extractum, 10-20 parts of soybean meal, 10-20 parts of beer grains, 15-25 parts of earthworm powder, 1-3 parts of soybean lecithin, 0.5-1.5 parts of bile acid, 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 obtained through fermentation on radix astragali, Chinesewolfberry fruits, tea leaves, sweet wormwood herbs, radix angelicae sinensis, wild cabbages, dendrobium nobile stems and cicada through bacillus subtilis; and the seaweed enzymolysis extracts are mainly prepared through enzymolysis on dried marine algae powder through papain and cellulase. The feed can enhance immunity, increase the quantity of beneficial microbes in the intestinal tracts and promote peeling of the prawns, and the mortality rate of the prawns at the exuviation period can be greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of feed, in particular to a compound feed for promoting shelling of prawns. Background technique [0002] Penaeus vannamei is commonly known as white limb shrimp, white shrimp, South American shrimp and so on. my country introduced Penaeus vannamei seedlings from the United States in 1988, and successfully carried out productive breeding and breeding in 1994. Penaeus vannamei is large in size, has strong disease resistance and adaptability, and has a fast growth rate. It can be cultured in low-salinity and fresh water. It can survive out of water for a long time, with delicious meat and a high rate of processed meat. Penaeus vannamei has become one of the main aquaculture aquatic products, and it is widely cultivated in Guangdong, Guangxi, Hainan, Fujian and other places in my country. [0003] Because fishmeal has the characteristics of high content of essential amino acids and fatty acids, low carbohydra...
