Free Amino Acid Content of Ovine Cervicovaginal Mucus1

Abstract

Estrous cycle synchronization of ewes has been accomplished by several methods. Progesterone or a derivative when fed, injected or applied with a vaginal sponge will inhibit estrus and ovulation. When treatment is stopped, estrus and ovulation occur in 1 to 5 days but mating at this estrus has given conception rates lower than those obtained with untreated animals (Hulet, 1966; Robinson and Moore, 1967; Cunningham, Deas and Fitzsimons, 1967).

Very little work has been reported on the physiological changes occurring in the reproductive tract during and following treatment with exogenous progestogen. It was found (Perkins and Goode, 1967) that the free amino acid content of oviduct fluid was altered when ewes were synchronized with progesterone. There was a distinct increase in free amino acid concentration of uterine fluids of rabbits treated with progesterone (Gregoire, Gongsakdi and Rakolf, 1961).

This research was designed to determine what effects synchronization of ewes with flurogestone acetate3 would have on the concentration of free amino acids in cervicovaginal mucus.
