¹Day of age, 41 = d immediately preweaning; 43,45,47,49 = every other day during weaning week; 51 = 2 d postweaning.

²Treatment C0 = control milk replacer, no visits; C1 = control milk replacer+ visits; A0 = high plane of nutrition milk replacer, no visits; A1 = high plane of nutrition milk replacer + visits.

³Vis = visitation of calves at 1030 and 1430 h.

⁴MR = milk replacer type, conventional or accelerated.

⁵Int = interaction between visits and milk replacer type.
