Britain s rarest breed of cattle, the Vaynol, was boosted further last week by the arrival of the first two calves of eight expected this year by the Rothesay herd, at Dumfries House, headquarters of The Prince s Foundation. Farm manager John Rowell was delighted to welcome a bull and a heifer, with the bull calf described as an excellent example of the breed and likely to go on to be a stock bull for another herd, helping to increase genetic diversity nationally. The farm team of John and wife Denise, who is education farm manager, as well as shepherdess Charlotte Darwent and John Irwin, have been working round the clock to help deliver calves.
