First, litter deodorization method In the litter mixed with sulfur, the litter pH value can be less than 7.0, this can inhibit the production and distribution of ammonia in the feces, reduce the chicken house air ammonia content, reduce ammonia odor . The specific method is to stir in the litter according to the amount of 0.5 kilograms of sulfur per square meter of ground and pave the ground. Second, the adsorption method uses charcoal, activated carbon, coal slag, quicklime and other substances with adsorption to adsorb odors in the air. The method is to use charcoal net bags to hang in the house or sprinkle some activated carbon, coal cinder, quicklime and so on, which can eliminate the odor in the air to varying degrees. Third, biological deodorization study found that many beneficial microorganisms can improve feed protein utilization, reduce ammonia excretion in feces, can inhibit the formation of harmful gases, reduce harmful gases in the air. There are many types of beneficial microorganisms (EM) commonly used at present, and the specific use can be based on product descriptions, mixing ingredients or drinking water, or spraying chicken houses. Fourth, the chemical deodorization method sprinkles a layer of superphosphate on the ground in the house. Superphosphate reacts with ammonia produced in chicken manure to produce odorless solid ammonium phosphate, which reduces ammonia emissions in the faeces and reduces odor in the chicken house. The specific method is to sprinkle 350 g of superphosphate on every 50 chickens. In addition, the use of chemicals such as hydrogen peroxide, potassium permanganate, copper sulfate, and acetic acid, which have an odor-suppressing effect, can also reduce the odor in the poultry house. The specific method is to use 4% copper sulfate and appropriate amount of slaked lime mixed in the litter, or use 2% benzoic acid or 2% acetic acid to spray the litter, which can play a deodorant effect. Fifth, Chinese herbal deodorization method Many Chinese herbal medicines have a deodorant effect, commonly used are leaves, Atractylodes, Daqingye, garlic, straw and so on. Specific methods: The appropriate amount of the above substance can be placed in the chicken house to burn, which can inhibit bacteria and deodorize.
