Implication

Study evaluates nutritional intervention effects on reproductive outcomes in heifers, suggesting efficient management strategies.

Key Points

This research aimed to assess how different post-weaning nutritional strategies affect reproductive development and productivity in primiparous beef cows.
Sixty Angus crossbred heifers assigned to three nutritional groups: low control, high control, and stair-step regimen.
Heifers monitored for average daily gain and pubertal status through weekly blood samples for plasma progesterone assessment.
Fixed-time artificial insemination followed by natural service post-experiment to evaluate pregnancy outcomes.
High control and stair-step groups showed greater average daily gain compared to low control (0.76, 0.68 vs 0.48 kg/d).
Puberty attainment was delayed in low control heifers compared to other groups.
Calving rate was higher in stair-step and low control groups compared to high control.
