The North East of England pioneered the development of livestock. The first pedigree herd-book for cattle in the world was produced in 1822 for the Durham Shorthorn, recording all breeding lines known up to that time.
This painting was done for the Earl of Strathmore in 1804 by George Gerrard. The Ox, a Durham Shorthorn, was bred by the Collings Brothers, who had learnt much from Robert Bakewell's ideas about selective breeding, continuing to implement them on their stock in the North East. The two brothers, along with Thomas Bates, are given much of the credit for the development of the Durham Shorthorn. The Ox was raised to 216 stone and later on was sold to John Day who exhibited him all over the country at fairs and shows, where he became a sensation. Day created a pamphlet which emphasised the advantages of this breed.
