Title: Impact of dietary spray-dried bovine plasma addition on pigs infected with porcine epidemic diarrhea virus Document date: 2018_8_29
ID: 0oyzg5tq_41
Snippet: The data from this trial indicate a beneficial effect of BovSDP on acute PEDV infection, which is similar to previous reports using the PRRSV infection model (Pujols et al., 2011) . Specifically, pigs fed BovSDP were able to clear virus shedding 2.1 d sooner than non-BovSDP pigs. The addition of BovSDP to the diet resulted in faster and stronger PEDV antibody responses and reduced PEDV shedding time compared with pigs with no BovSDP in the diet. .....
Document: The data from this trial indicate a beneficial effect of BovSDP on acute PEDV infection, which is similar to previous reports using the PRRSV infection model (Pujols et al., 2011) . Specifically, pigs fed BovSDP were able to clear virus shedding 2.1 d sooner than non-BovSDP pigs. The addition of BovSDP to the diet resulted in faster and stronger PEDV antibody responses and reduced PEDV shedding time compared with pigs with no BovSDP in the diet. Limitations of this study include the usage of one single virus titer and the low numbers of pigs tested. In addition, two PEDV pigs had to be removed early from the study, which could have impacted the outcomes. A larger study with higher numbers of pigs per group comparing porcine and bovine-derived SDP with multiple necropsy days should be conducted to further confirm the possible benefits of SDP in PEDV-infected pigs.
