Breeding broilers in broiler battery cages, don't look at the short feeding cycle, but there are also different stages of growth. The growth stages of broilers are generally divided into three stages: pre-feeding, mid-feeding and late feeding. Different stages have different common diseases. Farmers must do a good job in the prevention and treatment of diseases, so that broiler chickens can be safely slaughtered, and the farmers can improve their efficiency. The following is a description of the disease prevention points of different stages of broilers.

1. Pre-feeding period: The pre-feeding period generally refers to broiler chickens 1-10 days old, that is, the brooding stage. During this period, the farmers mainly control and control salmonellosis and colibacillosis. In addition, it is necessary to pay attention to the chicks from regular and well-conditioned hatcheries. Pay attention to the proper temperature and humidity of the house, and prevent the use of drugs in a timely manner. At the same time, feed some of the nutritional supplements to improve the disease resistance of the chicks, usually 3-5 days of medication can greatly reduce the mortality.

2. Mid-breeding: The mid-feeding period refers to the stage of broiler chickens from 20-40 days old. During this period of breeding, the farmers mainly need to prevent coccidiosis, mycoplasma disease and colibacillosis. At the same time, we must pay close attention to bursal disease, and the specific measures to prevent these diseases are as follows:

1) Improve the condition of the house, increase the ventilation of the house under the premise of ensuring the comfortable temperature of the house, avoid the harmful gases in the house, and disinfect the house and the chicken often.

2) Immunization is an important means of preventing disease, but immunization is not a small stress for the flock. Therefore, when immunizing or grouping, you should pre-feed some anti-stress and immune-enhancing drugs and try to arrange them at night to reduce stress. It is recommended that farmers choose to use several different drugs alternately when preventing disease.

3. Feeding late: The late feeding period refers to the broiler from the 45th day to the stage of the slaughter. During the breeding process, the farmers mainly prevent and control E. coli disease, atypical Newcastle disease and their mixed infections, pay attention to improve the environment of the chicken house and strengthen ventilation. Sterilize and avoid pathogenic microorganisms affecting the health of broilers. In addition, be careful not to disinfect the environment for 2 days before and after immunization. At this time, preventive medication, combined use of antibiotics and antiviral drugs, and pay attention to the withdrawal period.
