All heifers experienced complete luteolysis and ovulation after PG treatments, however, heifers in the TLD-1.5 and TLD-1 groups exhibited delayed progesterone (P<sub>4</sub>) decline, prolonged luteolysis, later estrus onset, and lower peak value of the estrous alarm (PA) than those in OSD.

The delayed luteolytic patterns induced by each regimen affected estrous expressions, as the serum P<sub>4</sub> concentration on Day 1 was positively correlated to the timing of highest estradiol (E<sub>2</sub>) as well as ovulation but negatively correlated to PA.
