  1. 1: Presented stratified by age group, sex or presented overall, depending on if a difference between groups was detected. a: RBC=red blood cell count; MCV=mean corpuscular volume; MCHC=mean corpuscular haemoglobin concentration; WBC=white blood cell count. b: λ=the transformation value from the Box-Cox transformation. c: 2.5 and 97.5 percentiles on untransformed data. d: B=both female and male; F=female; M=male. e: Y=yearling; S=subadult; A=adult. f: p-values are given for significantly different groups: A=p-value for age and AxS=p-value for age-sex interaction.
