Peter Rogers, [28 Jul 2022 at 11:17:39]: Good morning-can anybody give me some advice on how to abort a lioness please ? I see that she would need massive amounts of Alizine. She mated a good few times about 10 days ago - too early to check progesterone levels and the significance thereof as far as pregnancy is concerned ? Shaun Beverley, [28 Jul 2022 at 11:33:03]: (From Prof Henk Bertschinger) If you want to induce luteolysis for abortion you have to: • Wait at least 14 days after mating/ovulation for the corpus luteum to be susceptible to prostaglandins • In lions, we recommend 3 injections of Estrumate on consecutive days or alternate days @ 1/5th of the cattle dose.
