Table 3.
Percentage values of positive bacterial findings of deep nasopharyngeal swab samples of calves in six Finnish beef herds, results of three consecutive samplings at ages 3, 16 and 30 days combined.

N=number of calves per sampling. Pos=proportion of positive samples of all the samples from the farm. PM=Pasteurella multocida, TP= Trueperella pyogenes, F=Fusobacterium spp., U=Ureaplasma diversum, M=Mycoplasma bovis, RSV=respiratory syncytial virus, BCV=bovine corona virus.
a
Two samples were positive for two bacteria species, P. multocida+T. pyogenes and Fusobacterium spp.+T. pyogenes.
b
Two calves of farm E died after the first sampling which has been accounted for when calculating the proportions.
