The aims of this study were
to characterize the estrus behavior, ovulatory responses and progesterone profiles, and to
evaluate the in vitro embryo production (IVP) in this breed. In Experiment 1, ten nulliparous and
seven pluriparous females received medroxyprogesterone acetate (MAP)-containing sponges
(60 mg) plus 75 mg D-cloprostenol for estrus synchronization and their reproductive param-
eters were evaluated. In Experiment 2, oocytes obtained by laparascopy from hormonally
stimulated females (n = 15) were used for IVP. There was no difference ( p > 0.05) between
nulliparous and pluriparous goats in terms of estrus response (40.0% vs. 85.7%), time from
progestagen sponge removal to the onset of estrus (62.0
15.5 vs. 50.7
19.2 h; mean

duration of estrus (25.0

15.1 h), percentage of ovulating animals (60.0% vs.
