Safeguarding the health of the flock plays a crucial role. Before entering the chicks, the chicken cages and utensils should be strictly disinfected. The disinfection of the chicken coops in the chicken house is a very important part of the whole chicken raising process, to prevent the occurrence of infectious diseases.
1. Disinfection of utensils For water trays, troughs, trays and parts that are easy to handle and disassemble, soak them with 10% lime milk, then rinse them with water and let them dry.2. Sterilization of the brooder First clean the brooding house and thoroughly clean the dirt, dust, etc. on the ground, walls, roof and brooder bracket. Next, rinse the ground, cage, etc. with clean water, and spray disinfection with a 0.1 lat. Finally, fumigation is carried out according to the size of the brooding house. Before fumigation, the items used for brooding should be placed in the brooding house, and all windows and vents should be sealed and then fumigated. The specific method is to use 14g potassium permanganate and 28ml per cubic meter of space for disinfection. The ratio of potassium permanganate to formaldehyde is 1:2. If the house is seriously polluted, increase the amount of disinfectant, such as 30 g of potassium permanganate and 60 mL of formaldehyde per cubic meter of space. Chicken cage manufacturers advocate that the following points should be noted in this process.
(1) Fumigation and disinfection appliances should be larger to prevent splashing of disinfectant.
(2) Put potassium permanganate in the operation first, then slowly put formaldehyde into potassium permanganate, and quickly leave and seal the room.
(3) The disinfection effect is related to temperature and humidity. The higher the temperature and the higher the humidity, the better the disinfection effect. Therefore, before the disinfection, the temperature and humidity in the brooding house should be properly improved. The general indoor temperature should not be lower than 15- 20C.
(4) The airtight time should not be less than 24 hours.
(5) After disinfection, all doors and windows should be opened, at least one week of ventilation time to eliminate the odor in the house, so fumigation is best carried out half a month before the hatching. Prematurely, the disinfection effect will be reduced, and if it is too late, the odor will not be discharged.
