The coronavirus porcine epidemic diarrhea virus (PEDV) infects the cells lining the small intestine of a pig and, causes porcine epidemic diarrhea (PED). Owing to its highly infectious nature, PEDV has a substantial economic burden, which results in significant morbidity and mortality in piglets. In this study, the virucidal efficacy of a powder disinfectant containing a phosphate compound against PEDV was investigated. Virucidal efficacy was assessed as the infectivity of PEDV toward Vero cells after exposure of the virus to the disinfectant. PEDV was exposed to the disinfectant in the presence of either hard water (HW) or an organic matter suspension (OM). In the HW condition, PEDV was inactivated by 4-fold dilution of the disinfectant. In the presence of OM, the disinfectant showed virucidal activity with a 2-fold dilution. As the disinfectant possessed virucidal activity against PEDV, it should be an effective reagent for limiting the spread of animal viral diseases.

This study investigated the changes in appetite and behavior of cattle and pigs after foot-and-mouth disease (FMD) vaccination. This study involved ten calves and ten pigs, each divided into two groups of five animals. One group of each animal was vaccinated with an FMD vaccine (FMD-V), and the other group was used as a non-treated control (CON). Each animal’s appetite and behavior were observed before vaccination and for seven days post-vaccination. In the FMD-V groups, appetite and behavior scores during the seven days post-vaccination were significantly decreased compared to those in the CON groups. The only exception was the seventh day post-vaccination in the swine behavior scores
