Intrafollicular Injection of Prostaglandins in the Preovulatory Follicle of the Mare

The exact role of prostaglandins during the ovulatory process in mammals is not completely understood. This experiment was performed to evaluate whether intrafollicular treatment with PGE2 and PGF2 α administered in early to mid-oestrus (follicle diameter between 35-39 mm), would induce normal ovulation, corpus luteum formation and development, progesterone production, fertilization and embryo development. Six mixed-bred cyclic mares aged 3 to 12 years old and weighing between 350 and 550 Kg were studied during 3 oestrous cycles each, between September 2017 and January 2018.
