Chicken worm disease, clinical symptoms and performance:
2, just above the peak of the layout, the product is slowly decreased, and the egg is heavy, and the egg is small. About 10-15% of the chicken is white, check the crown.
3, high egg chicken, egg shell color is shallow. The brown shell egg whitening (obvious) accounts for about 10-30%.
4, in the egg chicken group, small part of the chicken, first remove the anus, then the anal, the death is increased.
5, the flock is thin, red, puzzle, according to enteritis, small intestinal catholic, intestinal syndrome, multiple medication still repeatedly, I can’t help it, I am very confused.
Second, mites prevention and control:
Regularly deworming: 60 days old young chicken, 120 days of initial egg hens, each deworming once. Adult egg chicken, April, August, all prevention of deworming once. Due to the summer and autumn season is the middle host flies and a large amount of breeding season, it is the stage of dewant infected aphids, so in August is especially important.
Biosafety: Chicken manure is often removed, fermentation treatment to kill the eggs in the eggs. The flies began to breed season, and cyclophropatidine was added to the feed, inhibited the propagation of fly maggots, and the rooster were regularly kill the ants, and the turtles and other beetles. Reduce intermediate hosts.
Clinical symptoms and prevention and control measures of chicken nematode:
After the chick infection, there is often digestive disorders, diarrhea constipation, sluggish diseases, sluggish, anemia, died, and final failure. Chicken infection does not appear obvious symptoms, but the amount of hen produces eggs can decrease, according to clinical symptoms, finding the eggs or cutting of the insectic ovity or cut into the insect body. Diagnosis. The main measures for this disease is the regular dewifep of the drug. Pinggui chicken on the ground, 2 preventive deworming each year, the chicken is carried out in January-November, the second in spring. The first deworming of the chick should be at 2-23 months, the second time in the late autumn.
Chicken tissue trichomoniosis 1, clinical symptoms:
The disease is refined, the appetite is reduced, and the feathers are fluffy, the wings are hanging, closed, chills, dysenters. Dedu yellow or light green feces, severe manure bleeding, and even discharge a lot of blood. The end of the disease, some doped chickens were circulated by blood circulation, and therefore, there was “blackhead disease””It is said. The course of disease is usually 1 to 3 weeks. There are still tissue mesens in the body of the disease. The tissue can grow up to several or months. Adult chickens have little symptoms.
2 , Pathological changes:
The main lesions of tissue trichomonia have occurred in the blindstormus and liver, causing cecalitis and hepatitis, so it is known that this disease is a disease. Generally only the pathogenesis occurs, sometimes two sides. On the 8th day after infection, the zelum has appeared in the case, thickening and congestive from the intestinal wall. The slurry and hemorrhagic exudate from the mucosa are filled with the intestinal wall; exudation of probers, formation Cheese-like “blindone”. Subsequently, the intestinal wall ulcer, sometimes perforations, causing peritonitis in the body. The liver disease changes in the 10th day after infection, the liver is swollen, purple brown, yellow or yellow green surface Localized circular, trapped necrosis stove.
3, prevention measures:
Since tissue trichomonia is spread through the 异 线, effective prevention is to reduce or kill To destroy these insects. Sunlight irradiation and drainous chicken farm can shrink the vitality of eggs, thus using sunlight irradiation and drying to maximize the 异 异. Chick should be kept in a clean and dry chicken house, Separate with adult chickens to avoid infection. In addition, adult chickens are regularly deworming.
