Teach you the prevention and control skills of "egg plague" in breeding organic geese.

Organic breeding goose "egg plague" is also known as infectious yolk peritonitis, and in some areas it is also called Escherichia coli reproductive organ disease. Its characteristics are as follows: female and male geese who specially infringe upon the laying period often begin to get sick in the early or middle stage of laying and stop until the end of laying, and the sick goose also loses its breeding value after being cured. The following is to introduce the prevention and control techniques of "egg plague" disease in organic breeding geese:

The main manifestations of the diseased female geese were depression, loss of appetite or abstinence, living alone or floating on the water, abdominal dilatation, laying soft shell eggs or deformed eggs, and the laying rate decreased in a straight line. There are wet and smelly feces around the anus, like egg patterns, which are mixed with egg whites and yolks, and most of the solidified egg whites or yolk blocks are like boiled egg soup. It is difficult for sick geese to walk, but the body temperature is normal, and the body temperature of some diseased geese increases. At the same time, the diseased geese also had sunken and dehydrated eyes, dry and cyanotic beak flippers, loose feathers, and the main symptoms of the diseased male geese were severe congestion of the penis, swelling 2 to 3 times, and the spiral seminal sulcus was difficult to see. there are sesame to soybean yellow purulent or cheese-like nodules in different parts, and some penis exposed in vitro can not be retracted. The scab was removed and the hemorrhagic ulcerative surface was removed, and the ability to mate was lost, but death was rarely found. Treatment: timely disinfection and vaccination if geese are infected with egg plague, what should farmers do? It is recommended that all diseased geese and suspected diseased geese should be quarantined. "through the above prevention and treatment measures, the disease has been gradually brought under control, except for the death of the seriously ill, the other basic recovery." In addition, the goose house and the feces produced were piled up and fermented, and all the dead geese were treated innocuously. "injection of goose egg plague aluminum hydroxide vaccine at 15 days before laying can effectively prevent the occurrence of the disease. Emergency vaccination is given to the infected geese. Seven days after injection of this vaccine, the epidemic of the disease can be effectively controlled. " Management: improve the environment of the goose house and improve the quality of the goose flock at present, due to the lack of large-scale goose raising technology, coupled with the lack of research on the prevention and control of goose disease, lack of experience, there are widespread phenomena such as simple goose house, high feeding density, poor ventilation, damp goose house, heavy breeding without heavy management, heavy treatment without prevention, lax disinfection measures and so on, resulting in the occurrence and spread of the disease. "choosing a good site is the key to raising good breeding geese." The organic goose breeding farm should choose leeward and sunny places close to rivers, reservoirs and abundant aquatic plants, and the water surface should have a certain width and depth, preferably the flowing river, and the water surface that cannot flow should be more than 1.5 meters deep, so as to prevent contaminated water from flowing into it. If you can not find a suitable natural water surface, you can build a pool artificially. Generally, the pool is 3 meters wide and 0.6 meters deep, and the length can be flexibly controlled according to the site conditions. It is suggested that the pool should not be built underground, the bottom of the pool should be higher than the ground plane, and water outlets should be left on both sides, which can be injected and discharged, which is conducive to disinfection and keep the water quality clean and unpolluted all the time. From the results of epidemiological investigation, it shows that the disease mainly occurs in the laying period, that is to say, the disease occurs when sexual maturity begins to mate, indicating that the transmission of the disease is mainly through mating. Therefore, half a month before laying, geese should check the reproductive organs of male geese while injecting egg plague vaccine. those with red and swollen penis or scabs are eliminated immediately. Goose anus around the damp, and with sticky feces should also be eliminated. Farmers should improve the quality of geese, eliminate all potential factors causing the disease in the bud, and ensure that organic geese produce healthy, sterile and high-quality breeding eggs. Hope that the above introduction of organic breeding goose "egg plague" disease prevention and control technology can bring help to everyone.
