Laparoscopic transfer of ovine and cervine embryos using the transpic technique. Abstract Text:

W H McMillan,D R Hall,

A transpic technique was developed to transfer embryos to 352 sheep and 4 deer recipients using a laparoscope, a modified pair of Allis forceps and a modified Cassou aspic normally used for laparoscopic uterine insemination. The overall proportion of uncomplicated transfers in Experiment 1 in 216 recipient ewes was 90.7% (range between groups 80 to 100%), 3.7% of the transfers were presumed to be loss of embryos during expulsion from the transpic, and 5.6% were apparent transfers into the uterine wall. In Experiment 2,83% of transfers into 136 ewe recipients were uncomplicated, 5% were presumed to be loss of embryos during expulsion, 1% was apparent transfer into the uterine wall, and 11% involved 2 attempts at transfer. Only 34% of 116 recipients receiving low-quality frozen-thawed embryos were pregnant and 24% of the 226 embryos survived to term. In contrast, high pregnancy rates (>80%) and embryo survival rates (>70%) were achieved following uncomplicated and twice attempted transfers of fresh embryos. Pregnancy rates and embryo survival rates were low (<2%) following the presumed loss of embryos during expulsion and apparent transfers into the uterine wall. All 4 deer transfers were uncomplicated and 2 2 good-quality embryos survived to term compared with 0 2 low-medium quality embryos. The transpic technique is a moderately invasive technique which permits fast (15 to 20/h) and reliable transfer of embryos in small ruminants. With appropriate care, nearly all of the embryos can be correctly placed in the uterus, and high pregnancy rates and embryo survival rates can be achieved using this technique.
