Problems solved by technology

[0002] Diethylstilbestrol is a synthetic estrogen. Because of its effects of promoting animal weight gain, increasing protein deposition and reducing fat deposition, it has been widely used as an aquatic feed additive to improve the conversion rate of aquatic feed and promote the growth of aquatic species. However, diethylstilbestrol It is a synthetic estrogen, which is not easy to degrade in the body. Long-term consumption of aquatic products containing diethylstilbestrol residues can easily lead to precocious puberty, growth retardation, abnormal development and lesions of the male reproductive system, and men and women are prone to breast cancer and ovarian cancer. Therefore, diethylstilbestrol accumulates in aquatic meat and seriously threatens human health through the food chain. The United States has banned its use as an animal feed additive since 1979 and restricted the import of animals that have used the drug and the food it produces from other countries. Due to people's desire to drive profit, diethylstilbestrol is still abused in aquaculture production, especially in shrimp farming

Embodiment 1

[0014] Embodiment 1. A treatment method for reducing the content of diethylstilbestrol in prawns. The prawns reaching the commercial specifications are caught, and the commercial prawns obtained after being caught are temporarily raised and sold on the market. Manually feed the detoxification adsorption feed once, and feed it at a ratio of 10g / kg, that is, feed 10g of the feed of the present invention per kg, and feed it between 8-9 o'clock every morning. Except feed, do not feed any feed;

[0015] Among them, the detoxification adsorption feed is made of 0.2 parts of astragalus gum, 30 parts of Ophiopogon japonicus enzymatic hydrolyzate, 120 parts of corn starch, and 2 parts of straw mushroom residue extract;

[0016] When making it, mix astragalus gum, radix radix radices hydrolyzate, corn starch, and straw mushroom dregs extract, add water so that the weight ratio of water in the mixture is 55%, and inoculate the activated glial spores after high-temperature sterilization ...

Embodiment 2

[0020] Embodiment 2, a treatment method for reducing the content of diethylstilbestrol in the prawns. The prawns reaching the commercial specification are caught, and the commercial prawns obtained by catching are temporarily raised and sold on the market. Manually feed the detoxification adsorption feed once, and feed it at a ratio of 10g / kg, that is, feed 10g of the feed of the present invention per kg, and feed it between 8-9 o'clock every morning. Except feed, do not feed any feed;

[0021] Among them, the detoxification adsorption feed is made of 0.4 parts of astragalus gum, 30-50 parts of Ophiopogon japonicus enzymatic hydrolyzate, 135 parts of corn starch, and 3 parts of straw mushroom residue extract;

[0022] When making it, mix astragalus gum, radix radix radix, corn starch, and straw mushroom residue extract, add water so that the weight ratio of water in the mixture is 56%, and inoculate the activated glial spores after high-temperature sterilization bacilli were ...

Embodiment 3

[0026] Embodiment 3, a treatment method for reducing the content of diethylstilbestrol in the prawns. The prawns reaching the commercial specification are caught, and the commercial prawns obtained by catching are temporarily raised and sold on the market. Manually feed the detoxification adsorption feed once, and feed it at a ratio of 10g / kg, that is, feed 10g of the feed of the present invention per kg, and feed it between 8-9 o'clock every morning. Except feed, do not feed any feed;

[0027] Among them, the detoxification adsorption feed is made of 0.5 parts of astragalus gum, 50 parts of Ophiopogon japonicus enzymatic hydrolyzate, 50 parts of corn starch, and 5 parts of straw mushroom residue extract;

[0028] When making it, mix astragalus gum, radix radix radices hydrolyzate, corn starch, and straw mushroom dregs extract, add water so that the weight ratio of water in the mixture is 58%, and inoculate the activated glial spores after high-temperature sterilization bacil...

Abstract

The invention relates to the technical field of aquaculture, and particularly relates to a handling method for lowering the content of diethylstilbestrol in prawns. The handling method comprises the steps of carrying out fishing for prawns which reach commercial specifications, and conducting temporary rearing on the fished commercial prawns and finally selling the prawns on markets, wherein during the process of temporary rearing, toxin expelling and adsorbing feed is manually fed to the fished prawns once every day, and the feed is prepared from astragali radix bbummorin, radix ophiopogonis zymolyte, corn starch and volvaria volvacea extracts. The handling method for lowering the content of diethylstilbestrol in the prawns can lower residual quantity of diethylstilbestrol in the pawns so that the commercial pawns can reach safe eating standards.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a treatment method for reducing the content of diethylstilbestrol in prawns. Background technique [0002] Diethylstilbestrol is an artificially synthesized estrogen. Because it can promote animal weight gain, increase protein deposition and reduce fat deposition, it has been widely used as an aquatic feed additive to improve the conversion rate of aquatic feed and promote the growth of aquatic species. However, diethylstilbestrol It is a synthetic estrogen, which is not easy to degrade in the body. Long-term consumption of aquatic products containing diethylstilbestrol residues can easily cause premature puberty, growth retardation, abnormal development and lesions of the male reproductive system, and men and women are prone to breast cancer and ovarian cancer. Therefore, diethylstilbestrol accumulates in aquatic meat and seriously threatens human health through the food cha...
