The Berkshire is a breed of pig cultivated in England.
The Berkshire Breed paved the way for better swine production and improvement in the United States and Europe, as well. Berkshires have had great influence upon the swine industry the past 100 years, and the Breed Association has made people aware of the importance of purebred animals. Types have changed in the swine industry due to economic needs, and Berkshires have played some of the most distinguishable roles in the Swine Industry. In the 1940's and early 1950's, Berkshires set a pace in market hog shows never to be surpassed - during this era, Berkshires won more consecutive Chicago International Truckload Championships than any other breed. Their winnings have never been duplicated.
During the past several years the Berkshire has made great strides of improvement towards meeting the demands of the swine industry. Selection pressure has been applied toward those traits of great economical importance - fast and efficient growth, reproductive efficiency cleanness, and meatiness.
This is the background of the modern Berkshire hog. It is important because it explains why the Berkshire is such a true breeder when crossed on other breeds or on common hogs. His characteristics have been established and purified over a very long period of time. Breeders have been working at the task of improving him as far back as any record goes. He is indeed a splendid example of an improved breed of livestock.
