Clive Rowland

Farm Manager

During the 20 years that Clive has managed our in-hand farm, he has developed an excellent reputation amongst Limousin cattle breeders for stock quality. He also manages Garrowby Farm's flock of 700 Mule ewes.

He selects the best of the progeny born on the farm to come into the herd. Clive’s almost encyclopaedic knowledge of the breeding history of the cattle is highly impressive!

Outside work Clive has an active family life and is kept busy with his three growing boys.
