Over the last 20 years Hampshire Down breeders have worked hard to breed faster growing, leaner rams with much better muscularity. Performance recording has played a vital role in this. Signet's Sam Boon comments: 'In 2000 only 2% of the Hampshire Down population had indexes over 200 – now over 60% of lambs are in this category. In fact over half of the lambs born last year had similar or superior genes to the top 1% of the lambs born in 2000. This is a remarkable achievement in a relatively short period of time. This chart demonstrates how the genetic potential of the whole population has been lifted.'
