There are a large number of harmful microorganisms in the nature of broiler equipment. The wastes, eggshells, fluff of the hatchery, plus the temperature and humidity conditions during incubation, are also a good environment for their reproduction and growth. If you do not pay attention to the strict disinfection of the hatchery environment, incubators and breeding eggs, once the epidemic is prevalent , Will bring catastrophic consequences.
Broiler equipment manufacturers recommend that the environment of the hatchery should be disinfected once a week. Commonly used disinfectants are: caustic soda, prostaglandin, etc., and the use concentrations are 1%, 0.3%-0.5%, and 5% respectively. Spray the disinfectant on the water according to the above-mentioned use concentration. The hatchery should be kept clean. It is strictly forbidden for non-workers to enter the incubator, and the staff should be strictly disinfected and changed before they enter the incubator.
Most incubators are disinfected with formaldehyde fumigation. Generally, 42 milliliters of formaldehyde solution plus 21 grams of potassium permanganate is used per cubic meter of space, and the fumigation is sealed for about 30 minutes under the conditions of a temperature of 20 to 2490 and a relative humidity of 70% to 80%.
The sterilization of the breeding eggs is as early as possible after the chicken body is produced. However, the centralized disinfection after collecting the eggs is often used in production. There are many disinfection methods and disinfectants used, but formaldehyde fumigation is commonly used. The dosage is 28 milliliters of formaldehyde per cubic meter of space, 14 grams of potassium permanganate, and fumigation for 20-30 minutes. Special attention should be paid to: The embryos of hatching eggs that are incubated for 24-% hours are very sensitive to formaldehyde. Do not use formaldehyde fumigation at this time. If disinfection is necessary, replace them with other disinfection drugs.
The incubator and hatching eggs should be disinfected immediately after hatching and placing on the plate. The method and the amount of formaldehyde are basically the same as the disinfection of hatching eggs. It should be noted that the time of using formaldehyde fumigation after placing the plate is shorter, generally 10-15 minutes.
Formaldehyde gas has a strong irritation to the mucous membrane of animals, so you should pay attention to your own protection when using it. After each disinfection, the formaldehyde gas in the incubator and the breeding egg store should be quickly removed. Some hatcheries have tried formaldehyde fumigation of chicks just out of their shells to control Marek's disease and pullorum. Production practice has proved that this method of raising chickens with chicken raising equipment is not easy to control due to the concentration of formaldehyde and fumigation environmental conditions. A little carelessness will cause the chicks to become blind, so it is not recommended to use it.
