Correlation of litters with diarrhea and maternal parity, prevalence of porcine RVC in diarrheic and healthy piglets, and piglets mean fecal RVC shedding titers. A Rectal samples were collected from diarrheic or healthy litters (n = 4). The number of litters with diarrhea was plotted against maternal parity and correlation determined using the spearman rank test (r_s = −0.629). Gilts (1^st parity) were significantly (p = 0.0002) associated with having diarrheic piglets. B RT-qPCR was used to test rectal swab samples obtained from diarrheic and healthy piglets for RVC RNA. C CT values from RT-PCR were converted to log10 GE/mL using a standard curve. Diarrheic piglets had significantly higher (p = 0.0419) RVC RNA fecal titers when compared with healthy piglets.
