Induction of abortion in queens by administration of cabergoline (Galastop) solely or in combination with the PGF2alpha analogue Alfaprostol (Gabbrostim).

The efficacy of cabergoline solely or combined with a PGF2alpha analogue in inducing abortion at different stages of pregnancy was investigated in 18 queens. The queens were assigned to two treatments: Group I ( n=10 )-cabergoline (15 microg/kg; daily, orally) and Group II ( n=8 )-cabergoline (15 microg/kg; daily, orally) combined with alfaprostol (10 microg/kg; every other day, subcutaneously). Each group was divided into two subgroups according to the duration of pregnancy when treatments started: Group IA ( n=8 ) included queens from Days 34 to 42 after mating.
