Open Data Verified Data
oxytetracycline is a kind of high quality and high efficiency feed additive for livestock and poultry, which has the function of disease prevention, health care and growth promotion, especially for pigs, chickens and other poultry and large livestock, and no drug residues, non-toxic side effects, do not produce drug resistance. Feed oxytetracycline on Gram-positive bacteria, gram-positive Pneumonia cocci, hemolytic Streptococcus, Staphylococcus aureus, tetanus Bacillus and other parts of the inhibition, high concentrations of bactericidal effect. For Bacterial enteritis, dysentery, leptospirosis, cholera and asthma have obvious effect.

| Use | oxytetracycline has inhibitory effect on both Gram-positive and gram-negative bacteria, and also acts as a growth promoting agent. For pigs under 2 months of age, the dosage is 15-50g/t; For pigs under 4 months of age, the dosage is 10-20g/t; For chicken feed, the dosage is 5.0-50g/t, the egg production period is disabled, the withdrawal period was 7 days. The antibacterial spectrum and antibacterial principle of oxytetracycline are basically the same as those of tetracycline. Cross resistance of bacteria to tetracycline, oxytetracycline and chlortetracycline. The product of intestinal infection (including amoebic dysentery) efficacy of chlortetracycline and tetracycline slightly better, other indications and tetracycline the same. broad-spectrum antibiotics |
| production method | oxytetracycline is a broad-spectrum antibiotic extracted from a culture solution of Streptomyces Typhimurium. produced by fermentation of Streptomyces rimosus, calcium carbonate is added to the fermentation broth, filtered, and the solid is dried. |
