Abstract: In recent years，a standardization of livestock and poultry large-scale breeding was vigorously promoted in China.But some problems were brought for large-scale breeding，such as pig manure and urine cleaning.Pig manure is main source of air pollution in pigsties.If the excrement is not cleaned timely，the excrement and urine is easy to decompose and produce NH3，H2S，CH4 and other harmful gases that are very harmful to human and animal health，as well as breeding bacteria，which is easy to induce respiratory diseases and infectious diseases.In order to ensure a healthy environment for growth of pigs，it is necessary to clean up the piggery regularly.Therefore，it is a feasible and effective way to carry out in-depth research on relevant technologies and supporting equipment of manure cleaning and gradually improve modernization and mechanization level of manure cleaning technology.Research status of technology and muck cleaning machinery both in China and other countries were introduced，and future development trend and suggestions were put forward.
