Disinfection is an important technical measure for large-scale chicken production
First, the choice of disinfectant Selected disinfectants. It requires no harm to humans and chickens, strong bactericidal power, and no drug residues in poultry or eggs. At the same time, use different types of disinfectants. Do not use a disinfectant fixedly. Commonly used water disinfection drugs include sodium hypochlorite, bleaching powder, dichloroisocyanuric acid, chlorine dioxide, etc.: The commonly used spray disinfection is divided into two types, one is a disinfectant with chicken spray, such as double quaternary ammonium salt and iodine disinfectant, Povidone iodine, peracetic acid, chlorine dioxide, etc.: The other is a disinfectant used in equipment in vacant chicken houses and chicken houses. Such as sodium hydroxide, cresol soap, peracetic acid, etc.: According to the specific circumstances of the use of disinfectants fumigation. Generally choose potassium permanganate and formaldehyde. Ethylene oxide and polyoxymethylene can also be used. Simultaneously. Each disinfectant has a certain range of disinfection and use characteristics. Organic chlorine compound disinfectants are suitable for use in acidic environments. Aldehyde disinfectants are suitable for use in alkaline environments. Quaternary ammonium salt disinfectants work quickly, work quickly, and perform well. Stability, low corrosion, low irritation, low toxicity, etc., less affected by organic matter and external conditions. Disadvantages are poor disinfection effects on certain viruses and spores; iodophor disinfectants are highly effective, low-toxic, and broad-spectrum, and have a rapid killing effect on various bacteria, viruses, spores, and fungi. The disadvantage is that it is susceptible to alkaline substances. It is also difficult for sunlight to accelerate the decomposition of iodine. Therefore, it is restricted when disinfecting the environment Second, the disinfection of the chicken house The chicken house should be "all in and out." After the chicken is sold or transferred out. The stricter disinfection of the chicken house. It is a powerful measure to eradicate infectious diseases. Good disinfection of chicken houses can provide safer conditions for each batch of chickens and increase the bred rate. The disinfection of sheds mainly proceeds from the following two aspects: 1. Cleaning and cleaning After the chicken is sold or transferred out, chicken manure, litter, dust on the ceiling, and spider webs should be swept out of the coop. The chicken coop, especially the floor, walls, and cages of the house, should be washed with a high pressure water gun. Thoroughly clean and wash clean. The sinks and other utensils should be cleaned. The walls should be brushed with lime water. Cleaning and rinsing should be carried out carefully and in accordance with a certain sequence. Generally, they are washed first and then washed. After the first roof and then the ground floor, from the far end of the barn to the door, first indoor after the environment. Do not leave corners, after careful cleaning and cleaning, not only can remove 80% to 90% of pathogens. And can greatly reduce the amount of organic matter such as feces. Facilitate the use of chemical disinfectants. After the floor has been dried, it is best to use a flame sterilizer for burning. Better results 2. Chemical disinfection 4. The ground wall dwarfs should be splashed with hot caustic soda or lime milk. For chicken cages and roofs, use non-corrosive disinfectant pharmaceutical high-pressure water guns or agricultural sprayers that are resistant to poisonous poisons and poisons. Conditional chicken farms, at this time the chicken house should be idle for 23 weeks before use, emergency, then fumigation. Close all doors and windows closed. Calculate the amount of formaldehyde and potassium permanganate used, depending on the degree of pollution in the chicken house increase or decrease. Closed fumigation 24 to 48 hours after ventilation. Increase the temperature and humidity before winter fumigation. After the above procedures disinfection of the chicken house. The killing rate of bacteria can reach 95% to 97% and is fully qualified. Third, the disinfection of chicken farms Chicken farm disinfection is an important measure to control the source of infection, cut off the route of infection, and improve the environment. The first method is to set a disinfection site in front of the chicken farm. Disinfectant. Disinfect the vehicles and personnel entering the farm. The second is to clean the farm once a day. Spray chicken farms once a week with 3% sodium hydroxide (commonly known as caustic soda and caustic soda); third, chicken manure and garbage should be promptly removed and transported to a place away from chicken farms, and be sterilized by fermentation or heaping manure . Fourth, the disinfection of staff Chicken farm staff is an important carrier of pathogens, so people entering the production area must be strictly sterilized. Workers in the chicken house in the chicken farmyard are forbidden to use skewer houses to prevent the infection of pathogens in the houses. when necessary. Workers wear uniforms, caps, shoes, etc., to stay in the original chicken house, and then change their own house when they specify the chicken house. Work clothes and caps should be cleaned and disinfected: Work clothes and caps should be cleaned and replaced regularly. After cleaning the work clothes can be sun-sterilized or formalin fumigation. Work clothes must not be worn out of the production area. Hand disinfection: The hands should be washed first and then soaked in a non-corrosive disinfectant, such as benzalkonium bromide, then rinsed with water and then wiped dry, foot disinfection: the staff should wear on the production area Water shoes or other special shoes. Through the pedal disinfection tank into the production area, chicken farm staff must replace the disinfected work clothes and rubber shoes before entering the production area, and can only enter the chicken farm after disinfection for about 10 minutes under the ultraviolet light. V. Sterilization during the rearing period During the rearing period, chickens are disinfected once a week with disinfectant, and the excrement should be cleared in time and must be disinfected. In addition, the feeding environment should be cleaned to minimize the number of pathogens in the house and the environment so as to prevent chicken diseases caused by pathogens invading the flock. In short, as far as chicken farms are concerned, they do a solid job of disinfecting and cutting off epidemic diseases. It is of utmost importance to create a good hygiene environment for poultry!
