Effects of different immunization schedules against CSFV and PRRSV on swine blood indices. A Mean lymphocyte proportions in different treatment groups. B Mean leukocyte counts in different treatment groups. C Mean neutrophil proportions in different treatment groups. D Mean hemoglobin concentrations in different treatment groups. E Mean red blood cell numbers in different treatment groups. F Mean median cell ratios in different treatment groups. Note: the bars are the respective standard deviation. Data are shown as the mean ± SD. Values with small letter (a) represent significant differences between S + PRRS group and control group within different immunization time (P < 0.05); Values with small letter (b) represent significant differences between S + PRRS group and S-PRRS group within different immunization time (P < 0.05); Values with small letter (c) represent significant differences between S + PRRS group and PRRS-S group within different immunization time (P < 0.05);Values with (*) represent significant differences between S-PRRS group and PRRS-S group (P < 0.05);(ns) indicates no significant differences among S + PRRS,S-PRRS, PRRS-S and control groups within different immunization time (P > 0.1)
