The Celtic Manor was accused of distancing itself from Newport in the 2010 Ryder Cup build-up, as it advertised itself as UskValley and being an hour and a half from London.
Colin Evans, who farms at Pant y Goitre farm in the UskValley in Monmouthshire, said between 20 and 25 lambs born to his 800 ewes appeared to have been affected by Schmallenberg - up to 5% of the flock.
