Recently, the incidence of serotonitis caused by duck cold has entered a high incidence period, the temperature difference between autumn morning and evening is large, there are many rainy seasons in some areas, the duck shed is wet, and the serositis caused by the cold and cold of ducks also makes breeding friends headaches. Today I will explain to you the prevention and treatment plan of serositis.
Serositis belongs to Lymus lycopheroliae, a bacterial disease that can be transmitted to healthy ducks through contaminated feed, water, feces, respiratory tract or digestive tract, and damaged skin. Once a large group of ducks with disease must be isolated, duck infectious serositis mainly affects 7-21 days of chicks, the incubation period is 3 days, and ducks under three weeks of age will have symptoms of weak legs, paralysis, and angular arch reversal after infection, and will die after 1-2 days.
The younger the age of the onset of serositis, the higher the death, so it is necessary to do prevention as soon as possible, after serositis, the spirit is not strong, the body temperature rises, the food production decreases, the eyes and nostrils have secretions, the white or yellow-green feces are pulled, the legs are soft and unstable, the walking difficulties are difficult, and if the individual is serious, there will be paralysis, inability to stand, there will be symptoms of turning over, kicking legs, and finally death.
There will be fibrillary exudates on the surface of the serous membrane of the anatomically dead duck, the surface of the pericardial liver or the air sac will obviously form the pericardial liver, the peritoneum will be chaotic and thickened, there will be mucus-purulent exudates in the sinuses, and the spleen will be enlarged.
There are two main reasons for duck serotonitis: first of all, the temperature difference is not large, especially the young duck, if the temperature difference between morning and evening is more than 5 degrees, the duck flock will be prone to colds, which will cause serous membraneitis; the other is that the environment is humid and poor ventilation, E. coli, stress reactions, which will cause serous membraneitis. If you want to prevent serositis, you must be a two-pronged approach to drug prevention and feeding management. The density of duck breeding should be reasonable, avoid stress, and the humidity in the duck house should not be too large, especially for ventilation.
If the prevention is prevented at the age of 9 to 12 days, the ducks are prevented for the first time with a stick and a single defeat, followed by the 21 days of age, and the 31 days of age is selectively prevented by the general.
The onset of the disease must be diagnosed with whether it is a mixed infection, and there is no need to blindly use drugs. That's it for sharing today.
