Abstract

This study was undertaken to determine if the synchronization treatment that accompanies superovulation in goats affected the ovulatory response and the incidence of premature regressive corpora lutea. Twenty eight Murciana goats were submitted, once in autumn and once in spring, to one of three different synchronization regimens based on fluorogestone acetate (FGA) sponges: treatment A, the standard short synchronization system; treatment B, the standard long synchronization system and treatment C, similar to treatment B, but with prostaglandin F-2 alpha injected two days before pessary removal. All animals were superovulated with 16 mg of follicle stimulating hormone (FSH). No difference in the percentage of animals with regressed corpora lutea was found due to season (27% in fall vs, 44% in spring, P = 0.196), due to the length of FGA treatment (41% with treatment A vs. 31% in treatment C, P =0.55), or due to the effect of prostaglandin F-2 alpha administration(33% in treatment B vs. 31% in treatment C, P = 0.89). The number of corpora lutea present at the time of embryo recovery did not differ among treatments (P > 0.05) or seasons (P > 0.05), but embryo recovery was lower (P < 0.001) in animals with regressed corpora lutea (1.2 +/- 0.6) than in animals with apparently normal luteal structures (8.9 +/-0.9), These data show that the synchronization regimen does not interfere with the superovulatory response and that high percentages of premature luteal regression can be associated with FSH-based superovulatory regimes. In the same way, it can be concluded that the administration of prostaglandin F-2 alpha does not increase the number of animals showing premature luteal regression.
