Optimisation and validation of insemination in sheep: technical and welfare objectives

Development of a non-traumatic and non-stress technique to artificially inseminate ewe.

The objective of this project is to develop a non-traumatic technique to introduce sperm dose into the uterus of the ewe. The current protocols and devices for artificial insemination in sheep are not efficient. There are various patented devices and protocols for intrauterine insemination in sheep, but they are very expensive (laparoscopy) or quite traumatic (Gourley scope, trans-cervical technique developed by GUELP UNIVERSITY researchers). In fact, the trans-cervical approach is very difficult in the ewe, because her cervix is small, very collagenous, with a tiny, tortuous path through it to the uterus. For this reason, artificial insemination procedures in sheep are performed trans-abdominally, via a laparoscopy. So, the risks include anaesthetic death, damage of the reproductive tract (which can affect future fertility), or even damage of other abdominal organs and traumatic death. We propose the use of a different combination of catheter and cervix dilator agent. The cervix dilator agent is the key factor in this process and the most innovative aspect. The source of this substance will be Super-Absorbent Polymers (SAP) technology. Porous polymer structures will be applied into the cervical canal and tested for cervical ripening. Alternatively, we aim to develop a simple and cheaper technique to inseminate the ewe through the abdominal wall: a modified laparoscope integrated with an insemination gun, to perform insemination through transabdominal incision only. These techniques will be applied in farms within the COVAP district. It is for this reason that research and definition of this sector and implementation of milk control in farms is important. The aim is to validate the reproductive techniques of the principal project at this level. Keywords: sheep, reproduction, insemination.
