Newcastle disease symptoms: 1. Several pigeons died suddenly without any symptoms. After that, most pigeons showed symptoms such as depression, rough feathers, drooping wings, motionless eyes, difficulty breathing, panting with their mouths open, and a lot of mucus flowing out of their mouths.
2. The appetite of sick pigeons decreased or disappeared, and some pigeons discharged white loose stools, green stools or bloody stools.
3. Some pigeons are paralyzed in the leg, stand unsteadily, stretch their heads forward, and die 2 -3 days later.
Reason 1. The disease is an acute or chronic infectious disease caused by salmonella, also known as pigeon salmonellosis.
2. The characteristic symptoms of sick pigeons are arthritis, diarrhea and motor nerve disorder. It is mainly transmitted through eggs and digestive tract, so it can lead to embryo death and pigeon disease.
3. Acute septicemia is mainly found in young pigeons, which is a great threat to pigeon breeding industry;
4. Chronic type occurs in adult pigeons. When the disease was prevalent in pigeon farms, its infection rate was 10%-25%, which mostly occurred in immature pigeons.
Newcastle disease treatment:? Firstly, the diseased pigeons were injected with Newcastle disease yolk antibody, each with 0.5 ml. At the same time, the whole group of pigeons were inoculated with Lasota vaccine through nose drops and eye drops for emergency vaccination.
Second, thoroughly disinfect the environment, feeding tanks and indoor appliances with Baidusha, while maintaining good ventilation and light.
Third, give the whole flock of pigeons oral rehydration salts. Every 200g is diluted with10kg clean drinking water and added with10ml sodium selenite and vitamin E injection, which can be drunk freely for 7 days. ?
Fourth, strengthen feeding management, and double the vitamins and trace elements in the feed for 5 days.
After taking the above control measures for 4 days, the sick pigeons stopped dying, the symptoms were alleviated, and the epidemic situation was controlled. Most sick pigeons basically returned to normal after 7 days, and 60% pigeons were protected.
Preventive measures: 1. For the early prevention of the disease, we should focus on the usual epidemic prevention and health work, strengthen feeding management, and do a good job in the environmental sanitation of pigeon farms;
2. Don't introduce pigeons from pigeon farms with this disease. When it is necessary to introduce it, it is necessary to conduct isolation observation and quarantine;
3. Pigeons cannot be mixed with poultry, nor can they be raised adjacent to each other, so as not to cause other diseases and bring unnecessary troubles.
4. Pigeons who have suffered from this disease should not keep seeds to prevent transmission through pigeon eggs. ?
5, found that sick pigeons should be immediately isolated, full-court disinfection, generally available 20% fresh lime milk disinfection floor, pigeon coop, feces, etc. , every day 1 time, until the epidemic situation stops, then do a comprehensive disinfection.
6. For drinking water, feed and sanitary sand, don't pollute the feces of sick pigeons. Drug therapy can reduce death and control the development and spread of diseases, but it can't eliminate pathogens in pigeons.
