Abstract

for their assistance on my research projects. I could not have completed my research projects without their wonderful help.I would like to thank my parents, Mark and Lisa Ruston, and my sisters, Adelaide and Madison Ruston, for their continuous support of my career goals. I would not have been able to accomplish this work without their love, support and guidance throughout my life. I would also like to thank my soon-to-be family, the Steckelbergs, for being my family away from home, here in Iowa, and supporting me through my research studies. I would also like to thank the Figurelle family, for all the great laughs and "pep" talks as I strived to work towards my career goals.Finally, I would like to thank my fiancé, Joel, for all his patience and love through my research studies and coursework. Your support has made this process much easier and enjoyable.

Presence of Porcine Circovirus Type 2 in the Environment of Farm Facilities without Pigs in Long Term-Vaccinated Farrow-to-Wean Farms
