Main symptoms and pathological changes of chicken pullorum

1: chicks: more weak chicks were hatched, and the navel was inflamed. They began to get sick and died at the age of 2-3 days. The death peak was reached at the age of 7-I0, and the death decreased gradually after 2 weeks. Tube, neck and mouth to breathe. The mortality rate of diseased chickens is 10% Mel 25%.

1. Prevention of Chicken White dysentery

(1) Quarantine purified chicken flocks: through serological tests, bacteria-carrying breeder chickens were detected and eliminated. The second test was carried out at the age of 60,7D, and the second test could be carried out at the age of 16 weeks. After that, the positive chickens were detected every one month, and the positive chickens were eliminated in time until the positive rate of the whole flock was less than 0.5%.

(2) strict disinfection: disinfection of eggs by ①. The eggs were picked and selected in time, and fumigated with 28 ml / m 3 formalin for 20 minutes at the age of 18-19 after egg picking, entering the incubator and falling to the plate at the age of 18-19. When the hatching reaches about 50%, fumigate and disinfect again with 10 ml / m 3 formalin in the hatching apparatus. A strict disinfection system was established in the ② incubator. Clean and disinfect the floor, utensils, feeding troughs, cages and drinking fountains of ③ chicks, breeding sheds and laying hens regularly. ④ should strengthen the management of Wei chicken feeding and pay attention to drug prevention.

At present, the occurrence of chicken pullorum is becoming more and more serious, and its fatality rate is up to 10%-60%, especially in the brooding stage, which often brings huge economic losses to the chicken industry. In the prevention and treatment of chicken pullorum, the traditional method is to use antibiotics. However, due to the emergence of drug resistance and the accumulation of antibiotics in the body, it has caused harm to the health of chickens, and the environmental pollution caused by excessive excretion of antibiotics into the environment, which will also have an impact on human health.
