Abstract

A slaughterhouse study commissioned by Florida Cattleman's Association in 2007 identified ovarian follicular dysplasia (OFD) as a primary cause of infertility in Florida beef cows. Ovaries with OFD have progressive bilateral development of solid clustered follicles containing multiple Call-Exner bodies that originate in the rete ovarii and the hilar region and progress into the cortex to eventually form bilateral Sertoli-Type Granulosa Theca Cell tumors (GTCT). The objective of this study was to access the usefulness of ultrasound for on-farm diagnosis of OFD.
