Abstract

This work studied the surgical technique for collecting embryos in the goat, using heterozygous donors for the 5/15 translocation, which were bred with translocated animals. At the same, time technical characteristics related to cryopreservation, thawing and cultivation of the structures were performed. Considering the superovulatory treatment, oestrus was observer 24 or 48 hours after removing the intravaginal sponge and 71 viable structures were yielded in 43 collections. The 1 -2 Propanediol proved to be an efficient cryoprotectant agent, and allowed the cultivation of all the embryos. This result was not observed when glycerol was used as a cryoprotectant agent. Adhesions due to multiple collections constitute a great challenge for the improvement of this technique, since they are considered a limiting factor to the use of donors in the beginning of their reproductive lives.
