Application of antibiotic-type plant extract feed additives in livestock and poultry breeding

Feed antibiotics have played a huge role in disease prevention and growth promotion of livestock and poultry. Over the years, with the development of livestock and poultry breeding, the problem of bacterial resistance and drug residues caused by antibiotic abuse has become increasingly prominent. Serious harm to life. In recent years, a variety of anti-disease and growth-promoting antibiotic substitute feed additives have begun to be used in the livestock and poultry breeding industry, and have achieved certain application effects. These antibiotic substitutes mainly include probiotics, acidulants, plant extracts, enzyme preparations and antimicrobial peptides.

Among them, the content of secondary metabolites in plants is rich, mainly including saponins, polysaccharides, alkaloids, volatile oils, polyphenols, flavonoids and other types. Studies have shown that eucommia leaf extract feed additives can promote the secretion of digestive enzymes by livestock and poultry, reduce the pH value of the intestine, promote the absorption of nutrients, and stimulate animal growth; it can improve the body’s immunity and inhibit inflammation; it can increase the content of myoglobin in muscles. Improve meat quality; it can clean up oxidative free radicals in the body, eliminate oxidative stress, and improve the body's antioxidant capacity. In recent years, the plant extract industry has developed rapidly. It is a source of medicine and food. It has developed into an emerging industry with broad market prospects not only in China, but also in European and American countries.

Plant extracts have played an active role in the growth and health of animals, and have also improved the ecological environment to a certain extent, and they have no pollution, no residues, and no side effects. However, farmers need to reduce the use of antibiotics by taking a two-pronged approach from feeding management and feeding environment.
