Before the chicks enter the house, the house and utensils should be strictly rinsed and disinfected (the house should be repeatedly disinfected more than three times). Three key points should be mastered during the entire breeding period: a disinfection pool should be set at the door of the house, and the disinfection water should be replaced frequently. Before feeding the chickens, change work clothes and pay attention to the disinfection of hands and shoes. Usually, we must insist on regular disinfection of the inside and outside of the chicken house.

Bacterial diseases and parasitic diseases prevalent in spring mainly include colibacillosis, salmonellosis, chronic respiratory diseases, coccidiosis, etc. The occurrence of these diseases is mostly related to age and environmental changes, which requires According to different situations, different medication prevention procedures are developed. Such as: Salmonella disease is prone to occur in brooding chickens; while chronic respiratory diseases and E. coli are prone to occur in winter and spring; coccidiosis mostly occurs in 15 to 60 days of age. To arrange the medication time correctly, we must first understand the diseases that are susceptible to infection at each age and each feeding stage, and timely administration of the medicine can achieve the purpose of prevention.
