How to Thoroughly Remove Harmful Gases from Chicken Coops When Raising Chickens

Litter deodorization method: Mixing sulfur into the litter can make the litter pH lower than 7.0, which can inhibit the production and release of ammonia from manure, reduce the ammonia content in the air of the chicken coop, and reduce the ammonia odor. The specific method is to mix 0.5 kg of sulfur per square meter of floor into the litter and spread it on the ground.

Use adsorbent substances such as charcoal, activated carbon, coal cinders, and quicklime to adsorb odors in the air. The method is to put charcoal into mesh bags and hang them in the chicken coop, or appropriately scatter some activated carbon, coal cinders, quicklime, etc. on the ground, all of which can eliminate odors in the air to varying degrees.

Many beneficial microorganisms can improve the utilization rate of feed protein, reduce the amount of ammonia excreted in manure, inhibit bacteria from producing harmful gases, and lower the content of harmful gases in the air. At present, there are many types of commonly used beneficial microbial preparations (EM). For specific use, they can be mixed into feed for feeding or mixed into water for drinking according to the product instructions, and can also be sprayed in the chicken coop.

Spread a layer of superphosphate on the ground inside the chicken coop. Superphosphate reacts with the ammonia produced in chicken manure to form an odorless solid ammonium phosphate salt, which can reduce the release of ammonia from manure and lower the odor in the chicken coop. The specific method is to evenly scatter 350 grams of superphosphate on the ground area where every 50 chickens are active. In addition, using odour-suppressing chemical substances such as hydrogen peroxide, potassium permanganate, copper sulfate, and acetic acid can also reduce the air odor in the chicken coop. The specific method is to mix 4% copper sulfate and an appropriate amount of slaked lime into the litter, or spray the litter with 2% benzoic acid or 2% acetic acid, both of which can have a deodorizing effect.

Many Chinese herbal medicines have a deodorizing effect, commonly including mugwort leaf, Atractylodes lancea, Isatis indigotica leaf, garlic, and straw. Specific method: place equal portions of the above substances in appropriate amounts inside the chicken coop and burn them, which can inhibit bacteria and also deodorize. The effect is best when used in an empty coop.
