The harmful gases in the house are mainly 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 efficiency of chicken production. Several methods for removing harmful gases from chicken houses are introduced for reference. Bedding deodorizing method. Sulfur in the litter allows the pH of the litter to be less than 7.0. This inhibits the production and distribution of ammonia in the manure, reduces ammonia in the air in the house, and reduces ammonia odor. The specific method is to stir in the litter at the amount of 0.5 kilograms of sulfur per square meter, and pave the ground. Adsorption method. Adsorptive substances such as charcoal, activated carbon, coal slag, and quicklime are used 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. Biological deodorization method. The study 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. 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. 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. Herbal deodorizing method. Many Chinese herbal medicines have a deodorizing effect. Commonly used are the leaves of Artemisia, Atractylodes, Daqingye, garlic, and straw. Specific methods: The appropriate amount of the above substance can be placed in the chicken house to burn, which can inhibit bacteria and deodorize. Plant extracts are based on plants as raw materials. According to the needs of the use of the final product extracted, through a physical and chemical extraction and separation process, one or more effective ingredients in the plant are obtained and concentrated, without changing the effective ingredients.

There are several classifications of some of the best-selling plant extracts in the world. For example, Rhodiola, Ginkgo biloba, Ginseng extracts are used in the field of brain strengthening, nourishment, and prevention and treatment of Alzheimer's; polypeptide extracts of green tea, Citrus aurantium, apple, and bitter gourd Used in weight loss, lowering blood sugar and preventing diabetes; Paclitaxel, tea polyphenols, theanine, bioflavonoids, such as lycopene, anthocyanins, etc. are used in natural anti-cancer fields; licorice, garlic, astragalus, soybean extract Used in the field of human immune system.
