The use of antibiotics in animal husbandry can usually be divided into two parts, one is antibiotics for curing diseases, and the other is growth-promoting antibiotics (The Ministry of Agriculture stated that: for growth-promoting antibacterial drugs, it will actively and steadily promote the implementation of “exit action.” According to the principles of risk classification and classification assessment, speed up the elimination of hidden danger varieties). Antibiotics for curing diseases are mainly used for the prevention and treatment of animal diseases and reduce the morbidity and mortality of livestock and poultry. Antibiotics for growth promotion are mainly used to promote animal growth, reduce the occurrence of diseases, improve feed utilization, and reduce production costs.
Classification of antibiotics for treatment
When choosing antibiotics for curing diseases, it is necessary to first diagnose whether livestock and poultry are infected with Gram-negative bacteria or Gram-positive bacteria. Always consult a veterinarian for diagnosis or isolation of infectious bacteria before medication.
(1) Antibiotics that mainly act on Gram-positive bacteria include penicillin, ampicillin, amoxicillin, cephalosporins, erythromycin, kitasamycin, lincomycin, etc.
(2) Antibiotics that mainly act on Gram-negative bacteria include streptomycin, gentamicin, kanamycin, neomycin, and spectinomycin.
