Recently, many friends who raise quails have reported that one or two frames of eggs are falling off every day, many soft eggs are broken, and the egg-to-material ratio is not comparable. They are also facing an injury rate of 40-50 quails a day, coupled with the current egg price trend. , it is really unspeakable, so today I will tell you what caused this, and share a recent case, I hope it will be helpful to everyone

A certain farm raises 5W quails, different According to the incidence, clinical symptoms, pathological necropsy changes and laboratory diagnosis, quail began to become ill and had high mortality to varying degrees. Based on the incidence, clinical symptoms, pathological changes in autopsy and laboratory diagnosis, the patient was finally diagnosed as jaundice peritonitis. The diagnosis and treatment are now introduced as follows: I. Incidence: The raised quails suffered from severe diarrhea and high mortality at 90 days of age; the egg production rate ranged from one to two baskets per day, which brought certain economic losses to the farm. .

Clinical symptoms

Watch The abdomen of sick quails is distended and heavy, with hard lumps around the cloaca, signs of severe diarrhea, mixed with egg white, coagulated albumen and small pieces of yolk, giving off a foul smell, slightly reduced egg production, and the skin turns purple. After autopsy of 5 sick and 12 dead quails, it was found that there was a yellow fishy smelly liquid and broken thick matter in the abdominal cavity, which is what we often call broken eggs. The internal organs in the abdominal cavity were covered with a layer of yellow or light yellow fibrous exudate. , adhesion of intestines and other organs

Laboratory diagnosis

This disease is prominent in the abdominal cavity and appears as yellow or light yellow viscous exudate adhering to the surface of the internal organs, as shown below important basis for diagnosis.

The solution is to use Yueke + Pollicon + doxycycline mixed with water for 5 consecutive days. While treating the chicken, use disinfectant to spray and disinfect the inside and outside of the chicken house once a day. After the medication, neomycin was added to the quail's drinking water every day for 3-5 days.

Experience After one course of treatment with the above regimen, the diarrhea problem of the quail was basically solved, and the death rate was also significantly reduced. Under the control, the egg production rate increases at a rate of 3~5% every day.

The causes of this disease are as follows

< p>1. This disease is generally caused by bacterial viruses such as colibacillosis and Newcastle disease that invade the reproductive system of laying quails, causing the follicles to necrosis and fall off into the abdominal cavity, leading to yolk peritonitis in laying quails. To deal with this kind of problem, we can use it twice a day a month, and one bottle can be used for 6,000 quails

2. Mechanical internal injuries caused by frightened or violent blows to egg-laying quails can also cause yolk peritonitis. If the temperature difference between day and night is large or the bird is frightened, drink Multivitamin in time

3. Inflammation of the reproductive system of laying quails occurs. Especially when the fallopian tubes are congested, bleeding or have a large amount of secretions, the inflammatory products adhere to the fimbria of the fallopian tubes, the bell mouth of the funnel cannot be opened during ovulation, and the eggs fall into the abdominal cavity, causing peritonitis, which is the main cause of death of the chickens. For such problems, Kangda should be used regularly for 6 days a month

4. Serious excess of E. coli in the shallow surface water that quails drink can also lead to the occurrence of the disease, that is, the maximum amount of E. coli allowed is 50 ml. This kind of problem requires testing and solving water quality problems (in individual areas)
