Chicken cages raise chickens at different stages of disease

The types of common diseases of broilers in different growth stages are different, so let's talk about the main points of disease prevention in the following stages.

First, the pre-feeding period (0-15 days old): This stage belongs to the brooding stage of broiler chickens. It requires the careful care of the farmers to ensure the survival rate of good brooding. The first point is that the farmer should raise the breeding farm with high level of management. Purchase qualified chicks. Another point is that farmers should pay attention to strengthening the disinfection of the house. At noon, disinfectants with small irritant and low toxicity can be disinfected with chicken to reduce disease transmission.

Second, the mid-feeding period (15 to 40 days old):

1. Control the humidity, keep the chicken house reasonably dry, and strengthen the disinfection of the environment, chicken cages and chickens. Choose several drugs with different modes of action to prevent coccidiosis.

2. Improve feeding conditions, reduce stocking density, and increase ventilation when the temperature is guaranteed.

3. Colibacillosis is mainly caused by contaminated feces floating in the air with dust and transmitted to healthy chicken through the respiratory tract. In particular, chickens are more likely to have E. coli after the Newcastle disease, resulting in a large number of chicken deaths. Prevention is mainly to strengthen environmental sanitation and disinfection work, cut off the route of transmission, strengthen ventilation, and remove harmful gases.

Third, the rear feeding period (40 days old to the bar): This stage belongs to the fattening period of broiler chickens. The key points of preventing diseases in this period are:

1. Strengthen antibody level monitoring. Urgent vaccination is required for Newcastle disease antibody levels that are not high and uniform.

2. Change the immunization method. The chicken's digestive tract and respiratory tract are susceptible to Newcastle disease virus. Newcastle disease immunization using the nose-drop method can stimulate the digestive tract and respiratory tract of the chicken at the same time, and produce strong resistance.
