Evaluates the impact of creep feeding and growth-promoting implants on calf performance, indicating enhanced growth in supplemented calves.

Assess the effects of creep feeding and growth-promoting implants on the growth performance of beef calves during the preweaning phase.
Stratified 72 cow-calf pairs by body weight into pastures.
Implemented a 2 × 2 factorial design with creep feeding and implants as treatments.
Calves were weighed at specific intervals leading up to weaning.
Analyzed data using generalized linear mixed models.
Calves receiving creep feeding were 17 kg heavier at weaning than non-supplemented calves.
Cows with supplemented calves gained more weight by weaning.
Implanted calves tended to weigh more at weaning.

Mazeres et al. (2026) studied this question.
