Abstract: Piglet diarrheal diseases have acute onset，large scale，rapid onset and high annual average incidence in swine herd，posing a huge threat to the global pig industry and leading to heavy economic losses. The causes of piglet diarrhea are complex and the main pathogens，causing piglet diarrhea，have the characteristics of natural recombination，continuous variation，a wide host spectrum and a variety of serotypes. With the emergency of more mutated pathogens，serious co ? infection and reduced vaccine protection，there is an urgent need to develop more sensitive and accurate tools，safer and more effective vaccines and to upgrade existing integrated prevention and control technologies. In this review，we summarize the causes of piglet diarrhea，the epidemic status，the key technologies research progress of integrated prevention and control，and propose to accurate diagnosis，rational selection of vaccines and strict feeding management，providing a basis and reference on the diagnosis and control of the disease.
