Background
The chicken raising is a common breeding project at present, and a large amount of chicken manure generated in a chicken farm is a great problem which troubles the existing chicken farm. Because the prior poultry is generally fed by high-protein concentrated feed, the urea content in the poultry excrement is far higher than that of other livestock excrement, the chicken excrement in a chicken breeding house can generate a large amount of ammonia gas, and the ammonia gas can react with moisture in the respiratory tract of the livestock to generate water-soluble corrosive NH4 +Ions further damage respiratory tract mucosa systems, reduce the immunocompetence of livestock and poultry, lead the livestock and poultry to be easily infected by germs, and bring serious disasters to livestock and poultry breeding. The ammonia gas enters a blood circulation system through a respiratory system and is combined with the hemoglobin, so that the heme is converted into the methemoglobin, the oxygen carrying capacity of the hemoglobin, the blood alkali storage capacity and the oxidation performance of the heme are reduced, further anemia and hypoxia appear in livestock and poultry, and the resistance of the organism to diseases is reduced. Researches show that high-concentration ammonia in a chicken farm can also influence the growth of poultry, the chicken raising cost is increased, and great health risks are caused to breeding personnel who frequently come in and go out of a chicken house.
The ammonia removal method for chicken farms at present comprises ammonia removal methods for removing ammonia by using feed probiotics, urease inhibitors, activated carbon and the like, but the existing method for reducing ammonia volatilization of chicken manure is high in cost and high in requirements on plant facility hardware, and the ammonia removal effect of an ammonia removal formula used on cow manure and pig manure is not high due to the fact that the nitrogen content in the chicken manure is far higher than that of cow manure and pig manure, so that the technical problem that how to remove ammonia by using easily available raw materials in a green and environment-friendly mode on chicken manure in chicken farms is always puzzled on practitioners, and the technical problem that the current chicken farm environment is improved and the working environment of the practitioners is urgently needed to be solved is solved.
