| description | The aim of this study was to investigate the possibility of performing inter-species embryo transfer under actual field conditions in the natural habitat of South American camelids. In this study embryos from llamas were transferred to alpaca recipients. In a parallel study alpaca embryos were transferred to llama recipients. All animals used were free of uterine and ovarian abnormalities detectable by rectal palpation and /or ultrasound examination. Embryos were harvested twice after single ovulation in 10 mated female llamas and non-surgically transferred to synchronized alpaca recipients. The field laboratory was located in the Peruvian highlands and was equipped with basic restraining pens but lacked electricity and running water. The use of alpacas as recipients for embryos of the slightly larger llama may be relevant for future preservation of the wild South American camelids. Furthermore we wanted to determine if it is possible to perform successful inter species embryo transfer under basic field conditions. The result of this study is promising with a 44% pregnancy rate after inter-species transfer. |

I detta examensarbete utreddes möjligheterna för lyckad embryoöverföring mellan två arter av små kamelider i deras naturliga habitat under fältmässiga förhållanden. I detta arbete beskrivs hur embryon från lamor flyttas till alpacka-surrogatmödrar. Parallellt med denna studie utfördes en annan studie med omvänd embryoöverföring. Alla djur som deltog i försöket var, enligt gynekologisk undersökning, fria från sjukdom. Tio stycken lamahonor parades naturligt varefter man samlade in embryon icke kirurgiskt och överförde dessa till hormonellt synkroniserade alpacka honor. Fältlaboratoriet som användes var beläget i det peruanska höglandet och saknade rinnande vatten samt elektricitet. Att använda alpackor som mottagare av embryon från den något större laman är intressant ur ett bevarandeperspektiv då de vilda små kameldjursarterna; vikunja och guanaco är hotade. Vidare undersöktes om det är möjligt att utföra mellanartlig embryoöverföring under basala fältförhållanden. Resultatet av studien är lovande med 44 % dräktighet efter embryoöverföring mellan olika arter. 2015-06-01 Second cycle, A2E NonPeerReviewed application/pdf sv https://stud.epsilon.slu.se/7973/7/tollig_s_150601.pdf Tollig, Signe, 2015.
