Recently, I saw a news on some livestock breeding industry websites that the animal husbandry authorities in Vietnam are about to include cysteine in the list of drugs banned by vietnamese animal husbandry. The policy is said to be implemented in December and inspections of cysteine use on farms have been initiated before implementation.
So, what exactly is cysteine? Why is Vietnam banning cysteine in livestock farming? Is this kind of thing still used in China's livestock breeding industry? In this article, I will analyze it for you.
Cysteine in the animal husbandry industry is regarded as a good effect of growth promotion products, it can promote the production performance of various livestock and poultry, improve the feed conversion rate of breeding, improve the quality of meat and carcass, improve immune function and reproductive performance, etc., so it is widely praised in the breeding industry and is widely used in animal production. Currently, cysteine hydrochloride is available in pigs, chickens, ducks, geese, cattle, sheep and aquatic animals, and numerous research trials have reported the accuracy of its economic efficiency.
However, there are different voices on the Internet about whether cysteine is a hormone, although I am a chicken farmer, but because I am not a professional chemist, I dare not take the risk of saying it. However, the Vietnam Animal Husbandry Bureau believes that the excessive use of cysteine may lead to the occurrence of cancer and some malignant diseases, so there is a ban policy at the beginning of the article.
By querying information on the Internet, cysteine in our country should be approved as a feed additive that meets national standards and is a legal and safe product. There are also many related products on the market for sale. It is normal for different countries to have different policies in the field of aquaculture, as well as different food and drug safety standards. But if cysteine is really like the Vietnamese describe, then our country's aquaculture industry should also be banned as soon as possible!
