J.  aSeasonal effecrs on caprine response to synchronization of estrus and superovulatory treatment.h[electronic resource]  c1992  aAbstract: Nubian doelings (n = 21, 7 of which were repeats) were synchronized and superovulated with Norgestomet ear implants and follicle stimulating hormone-pituitary (FSH-p) and were then mated during early and late periods of their breeding season in the southeastern United States. A 100% response rate to estrus synchronization treatment was found in doelings (n = 15, 2 of which were repeats) treated early in the breeding season, and the superovulation regimen resulted in the surgical collection of an average of 15.1 viable embryos per doeling. But only a 66.7% response rate to estrus synchronization treatment was observed in doelings (n = 6, 5 of which were repeats) treated late in the season; only 50% of these doelings (or 33.3% of the initial doelings treated) responded to superovulatory treatment, resulting in an average of 3.33 viable embryos collected surgically per doeling. Thus, a significantly higher number of viable embryos can be obtained from Nubian doelings when treated for estrus synchronization and superovulation early in the breeding season.  aEmbryo transfer  aEstrus synchronization  aReproduction  aSheep  aSuperovulation  aCabra  aCaprino  aCiclo Estral  aSincronização do Cio  aSuperovulação  aTransferência de Embrião1 aRICHARDSON, M.
