What is artificial insemination?

So you've heard about artificial insemination? Let's take a closer look. 

Artificial insemination (AI) is an advanced reproductive technology tool where semen is artificially deposited into an animal’s reproductive tract (Spanner, et al. 2024). Ewes have a corkscrew-shaped cervix which makes AI a bit trickier. AI in sheep must be done laparoscopically which includes a trained technician or veterinarian inserting two probes into the uterus of the ewe to dispense semen. Ewes must be sedated for this procedure. In addition, ewes must have an induced, synchronized estrus cycle for successful AI which includes a 12-14 day protocol focusing on a CIDR and hormonal injections.

​Conception rates from AI depend on a number of factors, such as time of year, semen quality, and ewe condition. However, conception rates of 50-70% can be expected per attempt. Artificial insemination offers producers benefits such as ability to utilize semen from other areas of the world, breed many ewes to one sire, and can be more cost-effective than purchasing your own ram.
