How to prevent and treat white chicken cocks?
In the hot and rainy season, chicken white-crown disease will also prevail. The disease is also known as Karniflovia. It was reported that the disease was first discovered in Vietnam in 1909. Because this protozoa can damage the red blood cells in the blood and cause bleeding in the chickens, the diseased chicken cocks are white and their paws are white. Because the disease is mainly in the media, especially Arakawa reservoir, the disease is closely related to the season of media activity and it is popular from April to November. The disease will cause a sudden hemoptysis and systemic bleeding of the chicks. This will result in anaemia in the laying hens. The egg production rate will drop sharply, causing serious losses to the chicken farmer. Therefore, it is necessary to do a good job of prevention and control of white-crown disease.
Etiology According to research, there are three kinds of living white cell protozoa parasitic in chickens, can cause acute and chronic white-crown disease. In summer and autumn, when the temperature is high and humid, a large amount of water is stored in the Hegou Reservoir, which is conducive to the large-scale propagation of the larvae. The larvae multiply the pathogenic spores and simultaneously inject saliva and sporozoa into the chicken body during blood-sucking. The pathogens then multiply in the body of the chicken. The proliferation of gametes, but also by blood sucking into the body of male and female gametes in the library to form oocysts, cycle cycle, and constantly invade the chicken body, easily lead to a large area of ​​the disease epidemic.
Clinical symptoms vary according to the number of different species of protozoa and the number of sporozoites and the age of infected chickens. In general, older chickens infected with small or severely infected sporozoites are less symptomatic after infection, but are overweight but suffer from lean growth, slow growth, frequent row of green stools, and anemia, and egg laying produces a drop in eggs. The mortality rate of young chickens at about one month of age is high, and the diseased chickens begin to suffer from mental deterioration, dizziness, and eyesight, and the feathers are upset and disorderly. The amount of food is reduced, and the gait is unstable. The feces is thin and yellow-green. Then chicken anemia, weight loss, crown and pale white, coughing blood, individual nosebleeds, pulling blood, and finally convulsions and death. Laying hens are more susceptible to infection than broiler chickens. The egg production rate drops sharply after infection, and shell and soft shell eggs increase.
Pathological changes Anatomically dead chickens can be seen in thin blood, subcutaneous muscle, liver, kidney, etc. have different sizes of bleeding and bleeding spots, abdominal cavity, trachea, hernia sac contains blood mucus.
Diagnosis is based on epidemiological and clinical symptoms and anatomic lesions to make a preliminary diagnosis, and take a drop of chicken blood or hemoptysis and hemorrhagic death. Make a thin slice, stained by wright or giemsa, observed under high magnification microscope, see blood There is a round, white blood cell gametocyte, diagnosed as white-crown disease.
The prevention and treatment program Once the disease is diagnosed, it should be treated immediately to prevent widespread epidemics. In order to help the majority of breeding friends, I have summarized a set of effective prevention and control programs for white-crown disease based on a number of expert opinions and empirical data for reference. Although there are more drugs currently available for white-crown disease, empirical studies have shown that the speed of the first dose is 100 ml/100 kg for the first dose, 100 ml/200 kg for the 2nd and 3rd days, and 2 days after 3 days of continuous use. Repeatedly used for 3 days, so in April and May of the popular season, use 2 courses every month, or use Feng Qiang to destroy the net and press 5000 g/ton of feed and mix, for 3 days, the effect is significant. When adding drugs, add more dimensions and better results. At the same time, it is more important to extinguish the media. The work of the library is even more important. In order to prevent contact between the poultry and the cockroaches, insecticides are regularly sprayed inside and outside the house in the epidemic season of white-crown disease, such as using 0.01% of trichlorfon or bromine. Cyanomethrin, poultry houses, doors and windows can also be considered closed with fine mesh screens to prevent the library from flying into the house. In addition, taking into account drug resistance, the same chicken farm should be replaced from time to time by another effective drug or by using two effective drugs simultaneously to better prevent and treat the disease.
