From: Introduction of a PRRSV-1 strain of increased virulence in a pig production structure in Spain: virus evolution and impact on production

Fig. 4

Evolution of mortality, feed conversion index and average daily weight gain in nurseries N2 and Nu4-nurs, after being infected with a highly virulent PRRSV-1 isolate, compared to nursery N4 that received piglets from a farm endemically infected with a PRRSV-1 strain of moderate virulence. The dotted read line indicates the median of each parametre before the outbreak. Data are shown per trimesters (Q1–Q4 each year)
