We have analysed the most favorable conditions for obtaining good fertility, prolificity and fecundity in non-lactating ewes treated with hormones (vaginally administered fluorogestone acetate and PMSG) and inseminated with either fresh (I5 °C) or frozen (― 19 60C) semen, without prior detection of oestrus. This study has shown that even during the breeding season, PMSG should be associated with progestagen, and that the results also depend on the quantity of hormone contained in the vaginal sponge. The technique of semen preparation and administration (quality of diluent, timing and number of inseminations, final semen concentration) is an equally important source of variation. The results presented indicate that the technique of synchronisation of oestrus with hormones associated with artificial insemination (fresh semen : i AI/female ; frozen semen : 2 AI/female) can be used throughout the year, but we find slightly better results with fresh semen than with frozen semen.
