PH values of saliva (A), faeces (B), blood (C) and urine (D). Early-weaned calves were weaned gradually between experimental d 28 and 42 of the trial. Late-weaned calves were weaned gradually between experimental d 98 and 112 of trial. Data shown as LSMeans with SE. Early-weaned calves from multiparous cows (earlyMC) n = 16, late-weaned calves from multiparous cows (lateMC) n = 16, early-weaned calves from primiparous cows (earlyPC) n = 15, late-weaned calves from primiparous cows (latePC) n = 12
