| quantitative polymerase chain reaction for porcine circovirus-2 in swine feces in a porcine circovirus disease-affected commercial herd and a nonaffected commercial herd. | this study examined if pigs in a porcine circovirus disease (pcvd)-affected herd (n = 100) had shed more porcine circovirus-2 (pcv-2) in their feces than pigs in a pcvd-nonaffected herd (n = 101), and if differences in shedding among production stages within and between the herds existed. the pcv-2 shedding was quantified by real-time polymerase chain reaction. the highest median pcv-2 shedding was found in the nursery of the pcvd-affected herd and in the grower of the pcvd-nonaffected herd. the ... | 2008 | 19252710 |
