This study evaluated the relationship between CL features assessed by ultrasound (luteal tissue area and blood flow, BF) or rectal palpation (size), uterine tone (UT), plasma progesterone (P4) concentration on Day 7 (D7) and subsequent pregnancy outcomes in bovine embryo recipients. A total of 163 cows and heifers were included in this study. The expected day of ovulation after the synchronization protocol was designated as D0.

- The study tested if starting a hormone protocol on Day 13 after Timed Artificial Insemination (TAI) improves conception rates in Nelore cows from two commercial farms.
- On Day 13, cows were divided into a Resynch group (receiving the hormone protocol) and a Control group (no additional protocol), with similar conception rates for the first TAI in both groups (around 50%).
- The second TAI for non-pregnant cows in the Resynch group showed a lower conception rate (42.8%), significantly influenced by farm-related factors.
