This disease can occur, rainy, sultry, damp season, poor ventilation, poor gauge, poor density and chicken group infection new city disease virus, chicken infectious cystic vesicle virus and chronic respiratory disease It is often a major cause of this disease. Then we will understand the origin of Chicken E. coli.
Second, the clinical symptoms of chicken coli

4, Chicken Escherichia coli Prevention
1. Do a good job in environmental hygiene, strictly disinfecting
(1) Do a good job in environmental hygiene in incubating workshops, breeding eggs and hatching The equipment is strictly disinfected to prevent the propagation of egg propagation and the horizontal infection.
(2) Do a good job in sanitation of feeding environments.

2. Strengthening feeding management, reducing stress
During breeding, during breeding, the stable temperature, humidity should be maintained, and the thief is preventing the thief.The air is fresh, prevent harmful gas pollution, control the breeding density, prevent excessive crowding, reduce stress, and clean up feces, do a good job of environmental hygiene, and maintain all utensils. In the breeding stage of breeding chicken, in addition to the above, it should pay attention to the transfer group, the stress of the open production, and the chicken pay attention to the stress of artificial insemination and the sinister disinfection of the insemination equipment.
Five, Chicken Escherichia coli Scheme
For the sick chickens, it is best to use the peasant bacteria, 300 kg against the water, preferably two times, drink evenly, reduce YAO to chick Stimulation, you can use 1 pack of 3000 chicken, free drinking water, 3-4 days twice, usually do the hygiene and ventilation work of the chicken house, maintain a good air zhiliao.
