How to thoroughly remove harmful gases from henhouse by raising chickens

The method of cushion deodorization mixed with sulfur can make the pH value of cushion less than 7.0, which can restrain the production and emission of ammonia in feces, reduce the content of ammonia in the air of chicken house and reduce the odor of ammonia. The specific method is to mix the sulfur into the cushion material according to the amount of 0.5 kg of sulfur per square meter to pave the ground.

Charcoal, activated carbon, cinder, quicklime and other adsorptive substances are used to adsorb the odor in the air. The method is to use a net bag filled with charcoal to hang in the chicken house or to sprinkle some activated carbon, cinder and quicklime on the ground, which can eliminate the stench in the air to varying degrees.

Many beneficial microorganisms can improve the utilization rate of feed protein, reduce the excretion of ammonia in feces, inhibit the production of harmful gases by bacteria and reduce the content of harmful gases in the air. At present, there are many types of beneficial microbial preparation (EM), which can be used according to the product description, which can be fed with mixed material or water, or sprayed with chicken coop.

Sprinkle a layer of superphosphate on the floor of the henhouse. Calcium superphosphate reacts with ammonia produced in chicken feces to form tasteless solid ammonium phosphate, which can reduce the emission of ammonia in feces and reduce the stench of chicken coop. The specific method is to sprinkle 350 grams of superphosphate evenly on the active ground for every 50 chickens. In addition, the use of hydrogen peroxide, potassium permanganate, copper sulfate, acetic acid and other chemical substances with anti-odor effect can also reduce the smell of chicken house air. The specific method is to mix 4% copper sulfate and an appropriate amount of hydrated lime in the cushion, or to spray the cushion with 2% benzoic acid or 2% acetic acid, which can play a deodorizing effect.

Many Chinese herbal medicines have deodorant effect, such as Artemisia argyi, Atractylodes lancea, Daqing Leaf, garlic, Straw and so on. Specific method: the above substances can be properly burned in the chicken house, which can not only inhibit bacteria, but also deodorize, and the effect is the best when used in an empty house.
