From the high fat and protein yielding "super cow" Bonnie Brae Emerald, out of an Ayrshire bred to a Canadian Ayrshire bull, four females were produced for the Whitefords - three by a Holstein bull and one by an Ayrshire-cross bull.
Stephen Borland - himself a Jersey breeder -chose a 75% Ayrshire female as his Supercow - Muir Royal Faith, from Andrew and William Watson.
Before FMD hit, Andrew used to keep Ayrshire Holsteins and pure Holsteins, and cows from this herd had taken the top spots at the Great Yorkshire Show, the Northumberland County Show and Ayr Show.
Now the 170-strong herd is about 70% pure black and white Holstein, 15% red and white Holstein and 15% Ayrshire Holstein, with cows bought from such notable breeders as the Fintdove herd in Hertfordshire, and the Cleevale, Primo and Upsall herds.
Shaun Dixon, aged 16, from Wolsingham, who was showing the interbreed champion calf for the Baynes, also won the Ayrshire champion handler award with the same heifer which was shown for the first time.
The North East Ayrshire Club, North Eastern Holstein Breeders Club, North East of England Jersey Club and the North East Shorthorn Club got together to hold their first all breeds calf show on August 31 at Thirsk.
