How to Treat Mixed Infections in Chickens? Detailed Guide to Prevention and Treatment
If a chicken has a mixed infection, the first step is to test the sick chickens to confirm exactly which diseases are involved in the mixed infection, and then treat them promptly. If Newcastle disease is detected, the sick chickens should receive emergency vaccination with the Newcastle disease vaccine, which can be given via drinking water, oral administration, nasal drops, eye drops, or injection at several times the normal dose. Antibiotics are highly effective against fowl cholera; antibiotics such as ofloxacin and norfloxacin can be given in drinking water or mixed into feed, twice a day. Then use a broad-spectrum anticoccidial drug in drinking water or mixed into feed for treatment. For respiratory diseases, if they are caused by Mycoplasma, tiamulin can be used for palliative treatment. If the respiratory disease is caused by Newcastle disease, treat the Newcastle disease first.
Mixed infections fall into several types, and you must first determine which is the primary disease. If it is a bacterial infection, broad-spectrum antibiotics can be used, which can effectively control multiple pathogens. If it is a viral infection, emergency immunization is required, with antibiotic treatment as a supplement. If it is a mixed infection of Newcastle disease and fowl cholera, treat Newcastle disease first, then fowl cholera. Newcastle disease is caused by a virus, and an attenuated vaccine can be used for emergency vaccination at 2-3 times the normal dose, while fowl cholera is treated with antibiotics. If it is a mixed infection of coccidiosis and respiratory disease, treat coccidiosis first, then the respiratory disease. Coccidiosis is a parasitic disease and can be treated with anticoccidial drugs. Respiratory diseases can be treated with erythromycin, chloramphenicol, and tylosin.
