The Sheep Ireland breeding programme has come a long way since its establishment in 2009. The number of pedigree breeders participating in LambPlus increased sharply from 2012 to 2017 and since then has plateaued at over 700 breeders.

This represents in the region of 33% of rams used annually for breeding, with another 7% of rams bred from pedigree flocks not participating in LambPlus. Sheep Ireland estimates that the largest cohort of rams used annually, at approximately 44%, are non-pedigree or crossbred rams.
