Abstract

Beef operations in Florida and other areas of the southeastern United States have a yearly calving percentage of less than 80%. Studies commissioned by the Florida Cattleman's Association in 2007 and 2016 found ovarian follicular dysplasia (OFD) as a primary cause of infertility in Florida beef cows. The later stages of OFD can be detected via ultrasound examination of the ovaries but earlier stages cannot be reliably detected utilizing ultrasound. The objective of this study was to examine the variation in ovarian gene expression between OFD cows and non-OFD cows. Identification of specific genetic profiles could aid in the development of an ante-mortem molecular test for early detection of OFD.
