Sažetak
This article examined the procedure of recipient does hormonal preparation and the technique of semilaparoscopic embryotransfer as well. Furthermore, the technique of direct transfer of thawed embryos was discussed as well as the obstacles associated with those procedures which should significantly contribute to genetic improvement of the flocs. The hormonal preparation of recipient does consisted of insertion of vaginal sponges through 11 days and application of eCG and prostaglandins on day 9. 24h after sponges were removed, detection of oestrus was performed. Seven days later semilaparoscopic direct transfer of thawed embryos were performed. Before the transfer, the uterus, ovaries and the quality of corpora lutea were visually evaluated by laparoscope. There should be at least one functional corpus luteum (even better 2 of them), red in colour and 6-7 days old in order to use the goat as a recipient. Late ovulations as well as early luteolisis should be avoided. The choosen horn was fixed and punctuated near the uterotubal junction in order to accomplish the transfer. It is important not to pass more than 1 minute from thawing till transfer of embryos. The direct transfer consist of thawing, after which the embryos are not passed through decreasing concentration of cryoprotector solutions but are quickly transferred into the uterine horn.
