dc.description.abstractExperiments were done to determine if inclusion of eCG and progesterone in the superstimulation protocol will increase the ovarian response and embryo production in wood bison, and to provide preliminary information regarding the effect of season. In Experiment 1 (anovulatory season), bison (n = 26) were synchronized by follicular ablation (Day −1) and given FSH on Days 0 and 2, and assigned to 3 groups: Progesterone (Days 0–4), eCG (Day 3), or progesterone + eCG. On Day 5, bison were given hCG and inseminated 12 and 24 h later. Ova/embryos were collected 8 days after hCG. In Experiment 2 (ovulatory season), bison (n = 24) were synchronized and assigned randomly to two groups in which superstimulation was induced with FSH, either with or without eCG, as in Experiment 1. No differences among groups were found in ovarian response or embryo production in either experiment. The follicular count at wave emergence was positively correlated with the number of large follicles at the end of superstimulation in all groups. A significantly greater number of follicles present at wave emergence in the anovulatory vs. ovulatory season was associated with a greater number of CL at the time of embryo collection, but only half the number of freezable embryos. In conclusion, the number of transferable embryos collected (1–2/bison) was higher than in any previous report, but was not attributable to the inclusion of eCG or progesterone in the superovulatory protocol. The apparent effect of season on oocyte competence, and not superovulatory response, is worthy of further investigation.es_ES
