Exposure to environmental stressors result in increased viral load and further reduction of production parameters in pigs experimentally infected with PCV2b.
Bottom Line: Porcine circovirus type 2 (PCV2) has been identified as the essential, but not sole, underlying infectious component for PCV-associated diseases (PCVAD).These stressors were identified recently as risk factors leading to the occurrence of severe PCVAD on a farm level.Furthermore, all stressors led to an increased viral load in serum and tissue as assessed by qPCR, although levels did not reach statistical significance.

Mentions: Each pig in the study was weighed weekly and the mass of feed consumed by pigs in each room throughout each week was recorded. The mean weekly mass (Fig. 1) and the mean average daily weight gain (ADG, Fig. 2) and feed conversion ratios (FCR, Table 1) were recorded for each room.
