Integration of Reproductive Ultrasound in Embryo Recipient Evaluation
  1. Pre-screening recipients before synchronization (Hour 1)
    Cyclicity of heifers (CL, RTS, Cervix); Cyclicity of early PP cows (CL, UT involution, post-calving trauma/uterine infection); Cyclicity of nutritionally restricted cows/heifers (CL, follicular activity, CL, uterus).
    Presenters: Luiz Nasser, BORN Biotechnology, Panama
    Brad R. Lindsey, Ovitra Biotechnologies, Texas
  2. Assessment of CL viability at time of transfer (Hour 2)
    1. No ultrasound use (rectal palpation of ovaries and uterus); traditional real-time US (CL, CL types – homogenous vs. fluid cavity vs. luteal cyst, uterine appearance);  Correlates to utilization rates, non-return rates, pregnancy rates.
      Presenters: Daniela Demetrio, Ruann and Maddox Dairy, California
      Nate Dorshorst, GenOvations, Wisconsin
    2.  Using ultrasound to specifically evaluate recipients’ endometrial/corpora lutea vascularization via color Doppler enhancement and how it might correlate to uterine/CL viability and thus, pregnancy rate/retention.
      Presenter: Sotirios Karvountzis, Bow Valley Genetic Limited, Canada
Panel Discussion – Luiz Nassar, Brad R. Lindsey, Daniela Demetrio, Nate Dorshorst, and Sotirios Karvountzis, will present a short summary of each topic presented followed by an interactive panel discussion between the experts and the audience.
