Abstract: | Six fallow does were inseminated directly into the uterine horns 72 h (three does) or 78 h (three does) after the removal of progestagen intravaginal sponges. Three does were inseminated with fresh (two at 72 h and one at 78 h) or frozen-thawed (one at 72 h and two at 78 h) semen. The semen used had been collected by electroejaculation and had been stored for 2 yr in liquid nitrogen in a Tris, citric acid, glycerol diluent containing 2.25% egg yolk. Three does each produced a live fawn to insemination and all does had been inseminated 72 h after removal of sponges; two with fresh semen and one with frozen semen. The remaining three does failed to conceive to insemination, but did produce fawns to mating at a subsequent estrus. |
