Prevention and treatment of cloacal inflammation in chickens
I. Overview of diseases:
Cloacal inflammation, commonly known as leucorrhea or retroanal gonorrhea, is ulcerative inflammation of the cloaca and anus. Diseased chicken anus out of a white sticky secretion, with a pungent stench, the disease is a kind of venereal disease of chickens.
2. Popular characteristics:
The pathogen can not be isolated and obtained, and the test shows that cloacitis can not be considered as an infectious or contact disease, and healthy chickens will not be infected in the period of natural onset (even if it lasts for several months). Even if the cloaca (cut cloaca) of healthy chickens was smeared with focus tissue, the disease could not be caused by the result. However, some people think that cock mating can spread to hens, so they should be isolated immediately after they appear.
Third, clinical symptoms:
The diseased chicken has no appetite, its physique is thin, and its crown, meat droop and face are not as bright red as those when laying eggs. The anus is red and swollen, the feathers around it are contaminated by foul-smelling thick substances, and the edges of the anus are often formed with false membranes. In severe cases, the tissue of the anal part fester and fall off, forming ulcers. Sometimes inflammation can spread to the rectum. As a result of anal stimulation, sick chickens work hard, often causing cloacal prolapse and anal pecking in chickens.
4. Anatomical symptoms:
It can be seen that the ovaries are undeveloped and there are suppurative foci in the fallopian tube and rectum.
5. Differential diagnosis:
Both the disease and salpingitis have symptoms such as red and swollen anus and malodorous secretions, which should be carefully differentiated according to their respective clinical symptoms and autopsy.
VI. Prevention and control measures:
1. Raise the diseased chickens in isolation immediately, cut off the dirty feathers near the anus, remove the necrotic tissue of the anus, and rinse them with a mild 3% chromic acid solution or 10% alum solution every 3 cents every 4 days, which can be cured in 4 days.
2. Apply 5% chlortetracycline ointment after local treatment according to the above method, and generally apply 2 Mel 3 times can also be effective.
3. Florfenicol preparations, AD3, tilmicosin and so on can be used in large groups.
