Abstract—The aim of this study was to evaluate whether prolonged treatment with acetate of melengestrol (MGA) influence or not, the ovarian follicular persistence in the ewe. We used 20 ewes with BCS 3.2 ± 0.3 (scale 1-5), 40.18 ± 5.8 kg BW and 3.25 ± 0.6 old years. All were confirmed by ultrasound, not pregnant. Treatment consisted of 0.22 mg of MGA daily during 17 days and follicular development was observed. The follicles were identified as an echogenic structures. The persistence or not follicular persistence was determined from changes in the size of dominant follicles in the days observed. During treatment, none of the ewes presented the dominant follicle persistent development. Is concluded that administration of prolonged treatment with MGA, not generates persistent follicle development in ewes.

Index Terms—Ewes, follicular persistence, melengestrol acetate.
