First, sulfonamides. These types of drugs are currently widely used artificial synthetic antibacterial drugs, with a wide range of antibacterial, stable, easy to use and so on. Commonly used sulfadiazine, sulfathiazole, compound sulfamethoxazole, compound sulfamethoxazole, compound pyrimidine and so on. Commonly used in the control of chicken psoriasis, coccidiosis, appendicitis and other bacterial diseases. However, these drugs have the side effect of inhibiting chicken egg production. They can only be used for chicks and young chickens, and laying hens must be banned from use.
Second, furans. Synthetic broad-spectrum antibiotics, commonly used furazolidone (because it has special effects on Salmonella-induced diarrhea disease, it is also known as furazolidone). Clinically, it is mainly used for intestinal infections such as chicken fleas, coccidiosis, chicken typhoid fever. However, this drug also has the side effect of inhibiting egg production. Layer chickens should not be used.
Third, chlortetracycline. For broad-spectrum antibiotics, there is a good effect on chicken white fleas, chicken typhoid, chicken cholera. Its side effects are not only a stimulatory effect on the digestive tract, but also damage the liver, but also combined with the calcium in the blood, forming insoluble calcium salts excreted, thereby hindering eggshell synthesis, so that the egg production of chickens decreased. Therefore, laying hens must be banned from use.
