Cervical AI Allows a Ram To Be Mated With 20-40 Ewes On a Given Day.
The process is currently limited to fresh semen and is reliant on semen of a motility score 4 or 5 being available on the day. Ewes are synchronised using sponges and PMSG (these must be obtained from your veterinary practice).
Conception rates of 65-75% are common, with some flocks having achieved +90% in the past, but are highly dependent on the quality and volumes of semen available on the day.
The process is quick and causes little stress to the ewe, but does require the ram to give multiple samples for insemination. Ewes are inseminated 52-58 hours post sponge removal and a schedule will be issued to you in advance of your AI day.
The Major Benefits of Cervical AI Are:
- Rams that are shared across various flocks, can cover a higher number of ewes than would be possible naturally
- Ewes that do repeat to Cervical AI tend to do so on the first cycle, leaving a compact lambing
- Cervical is considerably cheaper than other AI methods, which makes it a viable option for commercial and pedigree sheep breeders
Testimonials
I prefer Cervical AI compared to the Laparoscopic AI as there is less stress on the ewe. Ewes are brought in just before AI, no fasting or special treatment and are let out afterwards. In 2015 we had a 73% conception rate

Having had rams tested using the electro-ejaculator probe before we won’t be going down that road again. With this method of collection, you see the ram give the sample and it’s there for anyone to see, plain and simple
