用于动物保健预防的添加剂（Additive for the prevention of animal health） Additive for the prevention of animal health In order to promote animal growth and maintain health, we often add health and non nutritive additives to feed, such as: An antibiotic (pig, more knowledge, please click on the right side of the pig in more technology): Antibiotics are the metabolic products of microorganisms. Microorganisms that stimulate the synthesis of known or unknown nutrients and inhibit the competition of nutrients with the host (more pig knowledge, please click on the right side of the pig technology) to improve the intestinal absorption capacity. Therefore, antibiotics can enhance disease resistance and promote growth. Feed antibiotic (pig more knowledge, please click on the right side of more pig technology) elements can be divided into two categories: one is the common people and livestock antibiotics, such as penicillin, tetracycline, chlortetracycline, oxytetracycline, streptomycin and kanamycin; is a kind of special animal antibiotics, such as bacitracin, virginiamycin, tylosin streptozotocin, kitasamycin etc.. 1, oxytetracycline: belong to tetracycline (more pig knowledge, please click on the right side more pig technology) antibiotics, Chinas Ministry of Agriculture approved the growth promoting feed additive for oxytetracycline calcium salt. Oxytetracycline is a widely used antibiotic. It has a wide spectrum of antimicrobial activity and is effective for most gram positive bacteria and some gram negative bacteria. But there is little primality of oxytetracycline residues, many bacteria resistant to it. The dosage was: as a growth promoting agent, 5 * 10-6 * 7.5 * 10-6 eggs were banned. The stopping time was 1 weeks before slaughter. Note the antagonism of oxytetracyline with olaquindox. 2, Bacillus peptide zinc: its antibacterial spectrum similar to penicillin, very effective against gram positive bacteria, the Department of its gram negative bacteria, spiral bacteria, actinomyce
