Baseline clinical parameters (rectal temperature, weight, and attitude) of neonatal Holstein calves at enrollment (prior to treatment) into one of the three treatment groups (placebo, zinc methionine (Met), or zinc oxide (ZO)) from a double-blind block-randomized clinical trial on the effect of zinc as a treatment for diarrhea.

^aTreatment: Placebo = zinc-free oral rehydration solution (ORS); zinc Met = 80 mg of zinc/2 L of ORS (381.5 mg of zinc Met); ZO = 80 mg of zinc/2 L of ORS (99.7 mg of ZO).

^bNo significant differences in means within the same row (P < 0.05).

^cAttitude Scores: 1 = calf was standing, bright, alert, responsive, and had a good suckle reflex; 2 = calf stood only after stimulation and had a moderate suckle reflex; 3 = calf was recumbent, did not stand with stimulation, and had a weak or absent suckle reflex.
