Induction of abortion with prostaglandin F(2)alpha in gilts and their subsequent fertility.
Fourteen gilts were aborted (some of them repeatedly) by i.m. administration of 500/ug cloprostenol (PG) between 30 and 100 days of pregnancy so that the total number of PG-induced abortions was 19. Six of these gilts were allowed to terminate their subsequent pregnancy by farrowing. It was found that In a Trial under semi-production conditions the mean birth body mass of piglets from 11 gilts bred after previous PG-induced abortion was 1.48 kg as compared to 1.19 kg in the controls. The difference was significant (P<0.01).
