Performing AI 55 or 65  h after progesterone device removal did not differ in a 7-d progesterone-based protocol for timed-AI in Nellore suckled cows

This study suggests that performing AI from 55 to 65 h after the P4 removal in the 7-d-P4 protocol did not affect the reproductive perfo rmance in Nellore cows, and opens the possibility for producers to take more time to perform AI of cows in the field without affecting P/AI.
