Kansas Agricultural Experiment Station Research Reports
Understanding the magnitude of transmissible risk Porcine Epidemic Diarrhea Virus (PEDV)-infected feed imposes and establishing the minimum infectious dose of PEDV in a feed matrix are important components in strengthening virus prevention and control methods. In this study, an experiment was performed involving 30 crossbred, 10-d-old pigs that were used as a bioassay model for the minimum infectious dose of PEDV in feed. The PEDV was first diluted using tissue culture media to form 8 serial 10-fold dilutions. An aliquot of the original stock virus at 5.6 x 105tissue culture infectious dose/ml (TCID50/ml), each serial PEDV …
Utilizing Feed Sequencing To Decrease The Risk Of Porcine Epidemic Diarrhea Virus (Pedv) Cross-Contamination During Feed Manufacturing, L. L. Schumacher, R. A. Cochrane, J. C. Woodworth, C. R. Stark, C. K. Jones, Rodger G. Main, Jianqiang Zhang, Phillip Charles Gauger, S. S. Dritz, M. D. Tokach

Kansas Agricultural Experiment Station Research Reports
Understanding key points of potential cross-contamination during the feed manufacturing process is important to developing efficacious methods to control or prevent transmission of pathogens into swine diets. In this study, an experiment was conducted involving 30 crossbred 10-d-old pigs that were used as a bioassay model for Porcine Epidemic Diarrhea Virus (PEDV) to determine the effects of feed batch sequencing on PEDV cross-contamination and subsequent infectivity. PEDV with a PCR cycle threshold value (Ct) of 11 was uniformly mixed into 4.5 kg of swine diet using a stainless steel bench top mixer validated for mixing efficiency. The inoculated feed was …
