^abcMeans within row lacking common superscript differ (P < 0.05).

^aCalf divergent mineral intake classified calves as high (>50 g/d) or low (<50 g/d) mineral intake.

^bCow divergent mineral intake classified cows as high (>90 g/d) or low (<90 g/d) mineral intake.

^cRepresents average daily intake over the course of the 95-d monitoring period.

^dRepresents daily intake on the days cows and calves attended the electronic feeder.

^eTime represents the total time in minutes spent at the feeder over the course of the 95-d monitoring period.
