Oxytetracycline belongs to the tetracycline class and is a broad-spectrum antibacterial agent. It can increase the measured values of alkaline phosphatase, blood urea nitrogen, serum amylase, serum bilirubin, and serum aminotransferase (AST, ALT). Long-term medication should regularly check blood routines and liver and kidney functions, because oxytetracycline can easily cause liver toxicity.
Oxytetracycline can enter the fetus through the placental barrier and deposit in the calcium area of the teeth and bones, causing discoloration of fetal teeth, poor enamel regeneration and inhibiting the growth of fetal bones. There will be so-called "tetracycline teeth". However, birds do not have a placenta, but it may also cause the hardness of the egg shell during ovulation. Therefore, in order to avoid soft-shelled eggs, it is not recommended to feed oxytetracycline to female birds in estrus.
