“…[ 21 ] reported no significant differences when comparing an ORBS with a SID of 150 mM and 300 mM. More recent studies [ 33 , 35 ] evaluated the efficacy of different ORBS with SID concentrations in the range of 74–83 mM and although they report a comparative improvement in the acid-base status of the treated calves, it should be noted that, relative to the current study, the treatments were carried out over several days [ 33 ] and the calves were not acidaemic (mean blood pH value above lower reference limit) before the treatment [ 35 ].…”
