Table 1 Average (± standard deviation) of the daily RDS of the pigs for the three different periods

From: Efficacy of Mycoplasma hyopneumoniae vaccination before and at weaning against experimental challenge infection in pigs

Age range (days) V1 (n = 20) V2 (n = 19) PCG (n = 19) P value
29–47 0.07 ± 0.26 0.28 ± 0.69 0.11 ± 0.37 0.108
48–83 0.79 ± 1.30 0.62 ± 1.20 0.65 ± 1.19 0.626
29–83 0.54 ± 0.94 0.50 ± 1.03 0.47 ± 0.91 0.852
  1. Scores ranged from 0 (no coughing) to 6 (severe coughing undisturbed) (Halbur et al. [29]). Treatment groups: V1 (vaccinated before weaning, at 18 days of age), V2 (vaccinated on the day of weaning, at 21 days of age) and PCG (non-vaccinated). Overall and pairwise comparisons did not reveal any significant differences between groups for the three different periods. D48: experimental infection, D83: euthanasia
