More and more chicken farmers choose to raise broilers in broiler cages for sale. It is important to know that there are a large number of harmful microorganisms in the natural environment of broiler chickens. The waste, eggshell, and fluff of the hatchery, plus the temperature and humidity conditions during hatching, are also a good environment for breeding and growth. If you do not pay attention to the strict disinfection of the hatchery environment, hatching equipment and eggs, once the epidemic is prevalent Will have disastrous consequences.
Broiler farmers recommend that the hatchery environment and poultry farming cage equipment should be disinfected once a week. The concentrations used were 1%, 0.3%-0.5%, 5%. The disinfectant is sprayed with water at the concentration used above. The hatchery should be kept clean. It is strictly forbidden for the incubator to be a non-worker. The staff entering the hatchery should also be strictly disinfected and changed to enter. The disinfection of the incubator is mostly based on formaldehyde fumigation. Generally, 42 ml of formaldehyde solution per square meter of space is added with 21 g of potassium permanganate, and the temperature is 20 to 2490, and the relative humidity is 70% to 80%, and the fumigation is closed for about 30 minutes. The disinfection of the eggs is as early as possible after the chicken body is produced, but the production is often carried out after centralized collection of eggs. There are many methods for disinfection and disinfectants used, but it is commonly used to fumigate with formaldehyde. The dosage is 28 ml of formaldehyde per cubic meter of space, 14 g of potassium permanganate, and fumigated for 20 to 30 minutes. Special attention should be paid to: hatching 24-% of the eggs, the embryos are very sensitive to formaldehyde, do not use formaldehyde fumigation at this time, if necessary disinfection, can be replaced with other disinfectants.
Incubators and eggs should be disinfected after hatching and placing. The method and the amount of formaldehyde are basically the same as the disinfection of the eggs. It should be noted that the time to use formaldehyde fumigation after the tray is shorter, usually 10-15 minutes. Formaldehyde gas is strongly irritating to the mucous membrane of animals, and should be used for its own protection. The formaldehyde gas in the incubator and the egg store should be quickly eliminated after each disinfection. Some hatcheries have tried formaldehyde fumigation of freshly shelled chicks to control Marek's disease and chicken white mites. The production practice proves that the method of raising chickens in chicken equipment is difficult to control due to formaldehyde concentration and fumigation environment conditions. If it is slightly careless, it will lead to blindness of the chicks, so it should not be promoted.
