The harmful gases in winter and spring chicken sheds include ammonia, hydrogen sulfide, carbon dioxide, carbon monoxide, and methane. In the production of large-scale chickens, these gases pollute the environment of the chicken house, causing the onset of chickens or declining production performance and reducing the production efficiency of chickens. Here are five ways to eliminate harmful gases in the house, for reference.
First, litter deodorization method In the litter mixed with sulfur, the litter pH value can be less than 7.0, this can inhibit the ammonia in the feces to produce and distribute, 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, etc., 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 the ammonia excretion of feces and 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 the product description or mixed with water, and can also be sprayed.
Fourth, the chemical deodorization method spreads a layer of superphosphate on the floor of the chicken house, which can reduce the ammonia emission in the feces and reduce the odor of 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 aliquots of the above substances can be burned in a chicken house, which can inhibit bacteria and deodorize.
