The trial aimed at comparison of clinical effect on yellow and white scour, edema, paratyphoid, transmissible gastroenteritis, diarrhea and porcine epidemic diarrhea etc.
Piglets oedema disease come on quickly with high death rate, and was difficultly to be controlled by antibiotics, thus a type of new and high effective vaccine would be developed.
Porcine postweaning diarrhea and oedema disease are still responsible for considerable economic losses, and E. coli is a common porcine enteric pathogen.
