In February of this year, there were more than 70 cases of pork poisoning containing lean meat in Guangzhou. Earlier, similar incidents took place in Shanghai, Taiwan and other places, causing serious social concerns and people's concerns about the safety of livestock and poultry products. In order to fundamentally eliminate the harm of clenbuterol in the feeding of livestock and poultry products, Yin Yulong, a member of the Institute of Subtropical Agriculture, Chinese Academy of Sciences, has successfully developed a safe and highly efficient feed additive, arginine biosynthetic (AAA). Safe livestock provide reliable guarantees.
Clenbuterol, which causes food poisoning in livestock and poultry products, usually refers to a class of receptor agonists such as clenbuterol hydrochloride and dichlorohydrin hydrochloride. In the early 1990s, clenbuterol was used as a feed additive in foreign countries. After consumption, pigs and pigs promoted protein synthesis during metabolism, accelerated the conversion and decomposition of fat, and did not grow fat. However, as a feed additive, the use of a dose that is more than 10 times the dose of a person can achieve the effect of increasing the lean meat percentage. If you regularly eat this type of livestock and poultry products, it will cause chronic poisoning of the human body. If one intake is too large, there will be an abnormal physiological response to poisoning. Therefore, Clenbuterol is disabled.
In order to produce livestock and poultry products with high lean meat and safe food, low-cost, high-efficiency breeding can also be realized. Indigo et al. found that L-arginine (Arg) used in human studies in Europe and the United States is It plays an important role in the promotion of protein synthesis, enhancement of the body's immune system, and hormone secretion. It has been praised by scientists as a "magical molecule." Yin Yulong and others believe that if such arginine can be used as feed, it can ensure the safety of livestock and poultry products and human health. However, because arginine is currently used mainly in the human healthcare industry, it is expensive and cannot be used in the aquaculture industry.
How to get cheap arginine? Yin Yulong et al. took “Key Technology for Industrialization of Arginine Biosynthesis†as an important research task. After years of hard work, monosodium glutamate was synthesized using monosodium glutamate as raw material. The price was only arginine. One tenth. Adding arginine to the feed and combining it with the arginine decomposing enzyme in the pig produces arginine that allows the pig to eat, grow quickly, and have less diarrhea. A comparison of the effects of years of experiments at home and abroad and the use of tens of thousands of pigs shows that the results can increase the number of litters in sows by 10% to 30%, and at the same time increase the birth weight of piglets. Adding them to the feed of hogs and piglets can promote piglets Intestinal and vascular development, daily gain increased by 30% to 40%, and no antibiotics and stimulant residues.
The natural feed additive arginine, which is mainly composed of amino acid active ingredients, was introduced in Hunan. It was highly praised by experts at home and abroad who participated in the International Symposium on “Healthy Livestock and Poultry Breeding and Product Safety†recently, and believes that the results have solved livestock The problem of using lean meat extract, antibiotics, and high copper and high zinc heavy metals in poultry farming can help solve the safety problem of meat foods.
