Sheep

Arguably the most influential of Bakewell's breeding programs was with sheep. Using native stock, he was able to quickly select for large, yet fine-boned sheep, with long, lustrous wool. The Lincoln Longwool was improved by Bakewell, and in turn the Lincoln was used to develop the subsequent breed, named the New (or Dishley) Leicester. It was hornless and had a square, meaty body with straight top lines.^[3]

These sheep were exported widely, including to Australia and North America, and have contributed to numerous modern breeds, despite the fact that they fell quickly out of favour as market preferences in meat and textiles changed. Bloodlines of these original New Leicesters survive today as the English Leicester (or Leicester Longwool), which is primarily kept for wool production.

Cattle

He crossed long-horned heifers and a Westmoreland bull to eventually create the Dishley Longhorn. As more and more farmers followed his lead, farm animals increased dramatically in size and quality. In 1700, the average weight of a bull sold for slaughter was 370 pounds (168 kg). By 1786, that weight had more than doubled to 840 pounds (381 kg) ^{[citation needed]}. However, after his death, the Dishley Longhorn was replaced with short-horn versions.

Horses

Robert Bakewell bred the Improved Black Cart horse, which later became a Shire horse.^[4]

Influence on Darwin

Selective breeding, which Charles Darwin described as artificial selection, was an inspiration for his theory of natural selection. In On the Origin of Species he cited Bakewell's work as demonstrating variation under domestication, in which methodical breeding during Bakewell's lifetime led to considerable modification of the forms and qualities of his cattle, and the unconscious production of two distinct strains when two flocks of Leicester sheep were kept by Mr. Buckley and Mr. Burgess, "purely bred from the original stock of Mr. Bakewell for upwards of fifty years"^[6] with the unanticipated result that "the difference between the sheep possessed by these two gentlemen is so great that they have the appearance of being quite different varieties."^[7]

New Dishley Society

The New Dishley Society has been created to promote the memory of Robert Bakewell and of his contemporaries and students of his methods.^[8] The society aims to disseminate knowledge of his work and appreciation of his pioneering legacy in the breeding of improved farm livestock and better crop management. It supports research into the revolutionary agricultural techniques of the eighteenth and early nineteenth centuries and into the men who developed these techniques.
