. Almost 60% ofthe cows enrolled in the current study
had a CL at the onset of estrous synchronization for TAI.
At least two consecutive exams showing absence of CL are
required to ascertain anestrus. Herein, only one evaluation
of presence of CL was conducted, which may have led to
underestimation of cows that had initiated estrous cycles.
Additionally, cows that were well-fed and averaging (±SE)
172.1 ± 5.5 DIM, had a greater probability of having initiated
estrous cycle
