TRT = treatment; cow–calf pairs were provided with ad libitum access to a weekly 1.16 kg of DM × cow–calf pair−1-allotment of a custom-formulated and contractually-manufactured complete free-choice mineral supplement that contained amino acid complexes of Zn, Cu, and Mn, as well as Co glucoheptonate.

CNT = control; cow–calf pairs were provided with ad libitum access to a weekly 1.16 kg of DM × cow–calf pair−1-allotment of a custom-formulated and contractually-manufactured complete free-choice mineral supplement that contained a similar level of Zn, Cu, Mn, and Co from inorganic sources.
