However, the problem of shortage of breeding lands is increasingly prominent. Based on this problem, people have paid attention to building breeding, such as building breeding for pigs, from the traditional planar breeding layout. Building breeding has many advantages. First, building breeding saves land and is convenient for site selection. Using the method of building breeding, the breeding number per area of a breeding land can be multiplied, and the land utilization rate is efficiently increased. In addition, the range of building breeding has greatly increased. Mountainous and hilly areas where farms are difficult to build in the past can also be used for building breeding. Second, building breeding can effectively control the epidemic. The African swine fever in recent years has brought huge loss to the pig industry in China, which has prompted pig farming to become factory-like. Building breeding has the characteristics of a small scope of biosafety and epidemic prevention and clean and hygienic factory area, and floors are barriers, so that it is convenient to strictly carry out isolation, disinfection, and epidemic prevention mechanisms. Finally, it is convenient to achieve mechanical, informationized, and automatic management of building breeding.
However, a major problem in building breeding is how to treat livestock and poultry excrement. The inventor found that a treatment method requires manual transportation of excrement, which does not make full use of the characteristics of buildings, and it is more troublesome to treat and transport the excrement, and the treated excrement can also not be fully used. The two problems have troubled farmers and relevant local government departments, and have also become serious obstacles to the large-scale development of building breeding.
