The purpose of this study was to evaluate ovarian response, using transrectal ultrasonography, to two injections of Prostaglandin F2α (PGF2α) given at different intervals. Fourteen Bergamasca ewes were injected with an i.m. dose of PGF2α during the breeding season. Ewes were randomly alloted in two groups (n = 7) which received PGF2α 7 d (PG7) or 9 d (PG9) after ovulation (when the dominant follicle of wave 2 was expected to be in the growth and plateau phase, respectively). Ovaries […]
