Information

The problem of the abuse of antibiotics in feed has become increasingly prominent, resulting in reduced disease resistance of breeding animals, increased drug resistance of pathogenic bacteria, drug residues in products, and endangering food safety, which have severely restricted the development of the breeding industry. At present, Western developed countries are increasingly restricting the use of antibiotics, and have put forward stricter requirements on the drug residue restrictions of my country’s export of animal products. In particular, the detection of antibiotic residues in animal-derived foods has become the world’s meat trade. One of the important technical indicators and technical barriers. Therefore, the development and application of new feed additives without drug residues is extremely urgent.

The development and utilization of microecological preparations just solved the above problems. Microecological Preparation (Microecological Preparation), also known as probiotics, biocides, probiotics, probiotics, viable preparations, is a preparation of active microorganisms and their metabolites and growth-promoting substances that are beneficial to the host under the guidance of microbiological theory . Microecological preparations utilize the mutual antagonism, symbiosis and mutual growth of microorganisms, as well as the functions of these microorganisms to produce acid, degrade protein, decompose sugar and fat, degrade NH3 and H2S, and exert their functions to inhibit pathogenic microorganisms and decompose feed The middle protein is a polypeptide or amino acid, which degrades the residual ammonia nitrogen and nitrite in the water. It is a natural biologically active preparation with no toxic side effects, no drug resistance, and no drug residues. It adjusts and maintains the microecological balance in the gastrointestinal tract by promoting the growth of beneficial microorganisms in the intestine and inhibiting the growth and reproduction of harmful microorganisms. To achieve the purpose of preventing diseases and promoting growth. At the same time, these microorganisms can also produce growth-promoting factors, a variety of digestive enzymes and vitamins, thereby promoting the digestion and absorption of nutrients and the growth and reproduction of animals. In addition, these microorganisms can also produce immunologically active substances such as immunomodulatory factors and interferon, which can stimulate the growth and development of local immune organs in the intestines, enhance the body's immunity, and prevent the occurrence of various diseases. It is a new type of green and environmentally friendly drugs. Replace antibiotics.

The earliest research and application of microecological preparations for livestock and poultry can be traced back to 1947. Monhard first discovered that the use of lactobacillus to feed piglets can effectively increase the weight of piglets and improve their health. In the 1970s, the United States took the lead in using microecological preparations, with very obvious effects, showing the incomparable advantages of antibiotics. In the 1980s, microecological preparations began to be popularized around the world and gradually recognized by the world. Especially in the past ten years, the development of probiotics has been particularly rapid. US FDA regulations: 42 kinds of microorganisms are allowed to be used as probiotics. my country's Ministry of Agriculture (2003) announced that there are 15 species of feed-grade microbial additives that can be directly fed to animals, including Bacillus subtilis, Lactobacillus casei, Lactobacillus lactis, Bacillus cereus, Lactococcus and yeast.
