Biological deodorization method: Research has found that many beneficial microorganisms can increase the utilization of feed protein, reduce the ammonia excretion in the faeces, can inhibit the generation of harmful gases by bacteria, and reduce the harmful gas content in the air. At present, there are many types of useful microbial preparations, which can be used according to the product instructions, such as seasoning or water, or sprayed.
Chemical deodorization method: Sprinkle 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.
