We are talking about a select few but they're not like Halley's comet!So that's 1 every 10 years...

ummm i'd sooner have a good set of twins not alot of point breeding worki'm keeping all my triplet lambs entire this year and see what,if any, i like

yea like this http://www.genomnz.co.nz/our-services/booroola/Surely numbers are determined by the ewe, by the number of eggs she produces to be fertilized where as the sex is decided by the Y chromosome carried by the male!
In a small flock maybe, but would come across such animals far more regularly in a larger flock of course.......

Litter size used to be a huge problem within the lleyn breed. A farm near here used to keep them and although they would scan at around 200% there could be lots of singles as well as triplets quads and even quins.But her genes will be passed to her son too. It fully depends if it is a maternal or terminal male progeny you are after.
For you, triplets would be kiss of death. I believe the new Lleyn Index rewards 'twinning' as litter size is taken into account. This is a real strength in the breed I think.

Vets reckon it's about 10% heritable from the male which doesn't sound much but mounts up over time.

Agreed, but some breeders have possibly gone too far to drive prolificacy down, and avoid triplets altogether? I know of someone that was very big on Lleyns, but has now changed over to Romneys as the prolificacy of his Lleyns was dropping every year (Rams bought from a breeder doing as above), getting down to 160% scanning was the final straw IIRC.
I know he would have been buying on ebv's, but whether he was taking full account of litter size ebv, I don't know.
In a modern Lleyn, personally I wouldn't be looking for a negative litter size ebv, unless I was looking to reduce lambing %age significantly from 200.

seem to recall a fella on another forum says it was close to nothing as a trate not sure on that thoVets reckon it's about 10% heritable from the male which doesn't sound much but mounts up over time.
Off on a tangent abit, but how successful have people been cross breeding Lleyns to have a more consistent twinning, (instead of trips and singles), yet still maintain a decent lambing %? Were trying to incorporate NZ texel into the mix, partly for this reason among others. But has anyone had any good results? Sorry to hijack

It's early days, but this year I had 1 set of triplets and good amount of twins from lleyn x Aberfield shearling ewes.Off on a tangent abit, but how successful have people been cross breeding Lleyns to have a more consistent twinning, (instead of trips and singles), yet still maintain a decent lambing %?
