The scientific, efficient and safe use of veterinary drugs not only timely prevents and treats animal diseases and improves the efficiency of farmer farming, but also has important significance for actively controlling and reducing drug residues, improving the quality of animal products, and providing “green†foods.
1, fully consider the characteristics of drugs. Internally absorbed drugs can be used for systemic infections, oral administration of drugs that cannot be absorbed, such as furazolidone, sulfaguanidine, colistin sulfate, etc., can only be used for gastrointestinal infections, and general antibiotics rarely enter the cerebrospinal fluid Only sulfadiazine sodium can be accessed, and sulfadiazine sodium should be preferred when treating brain infections.
2, choose the right way to use drugs. Bitter stomach medicines such as gentian glycosides, breve, etc., can only stimulate the taste buds and strengthen the secretion of saliva and gastric juice through the oral route. If gastric tube administration is used, the drug will not enter the stomach directly through the mouth and it will not The role of stomach.
3, pay attention to the effective concentration of drugs. For intramuscular injection of kanamycin, the effective concentration is maintained for 12 hours. Therefore, continuous intramuscular injection of kanamycin should be performed within 10 hours. Penicillin injections should generally be repeated once every 4 to 6 hours, and the procaine prolactin can be administered once every 24 hours.
4. Try to use drugs with various effects or special effects. In the case of jaundice and white fleas in young animals, berberine is used as early as possible; apramycin treatment of E. coli and Salmonella in poultry is very effective.
5. Pay attention to the incompatibility between drugs. Acidic drugs can not be mixed with alkaline drugs; antibiotics and adsorbents should be banned when oral live bacterial preparations are used; sulfa drugs are combined with vitamin C to produce precipitates; sulfadiazine sodium injection and most antibiotics will produce turbidity and precipitation. Or discoloration should be used alone.
6. Pay attention to the animal species differences. Pigs and dogs are easily vomited animals. In the early stages of poisoning in pigs and dogs, emetic drugs may be used. However, equine animals are not prone to vomiting. Therefore, emetic drugs cannot be administered.
