Interpretive Summary:

Technical Abstract: Ultrasonography is a powerful technology that can be used to improve reproductive management in heifers. By counting the number of antral follicles observed on an ultrasound screen the practitioner can gather additional information when reproductive tract scoring, because the number of antral follicles is predictive of the status of the ovarian reserve. The number of antral follicles is also predictive of response to exogenous gonadotropins and can be used as a screening tool to remove poor responders before time and money is squandered trying to recover oocytes or embryos.
