Fertilization and early embryonic development in androstenedione-immunized Merino ewes



Fertilization and early embryonic development in androstenedione-immunized Merino ewes



Journal of Reproduction and Fertility 78(2): 423-431



Ewes were immunized against androstenedione (Fecundin) and were assigned to be mated 14 days (179 ewes, group 1) or 25 days (174 ewes, group 2) after a booster immunization with Fecundin. The anti-androstenedione titres at these times were 6790 and 3240 resp. (P<0.01). The remaining 169 ewes were untreated controls (group 3). Ewes were mated to entire rams (12 rams to 180 ewes) at their 2nd oestrus after synchronization.
