Interpretive Summary:

Technical Abstract: Ultrasonography serves as a diagnostic tool for understanding what is occurring at the microscopic level in the bovine ovary. Situations exist, however, in which genetic or nutritional influences can alter the population of microscopic follicles without altering the number of antral follicles observed on the ultrasonically, because correlations between preantral and antral follicle numbers are not 100%. Investigation of the mechanisms controlling establishment of the ovarian reserve and regulation of preantral follicle growth may improve both reproductive management of developing heifers and diagnostic capabilities.
