Sir; I applaud the initiative to eradicate scrapie from the nation's remaining sheep flocks. I believe the first cross from the once rare Wensleydale sheep have a 90% resistance to the disease. This inbuilt characteristic sounds like a gift to commercial sheep breeders and owners of pedigree sheep who persevered with an unfashionable breed. Times change! Can older, healthy sheep not be used for mutton pies, still made by a few Scots butchers? Is this a national brand waiting in the wings for promotion? Light lambs need not be destroyed but should be marketed and eaten. G Lund Girvan {{LETTERS }}
