Choosing a Breed. The question "Which breed shall I raise" confronts every purebred hog producer. He may have a personal preference which will assist him in choosing a breed. If he has no such preference, it would be well worth while to consider the most popular breed in the community. This procedure will help the breeder to gain popularity, in establishing a reputation, and in attracting more buyers into the community. Each breeder may believe he has the best breed because of size, feeding qualities, higher dressing percentage or some other factor; but there is more difference within breeds than between breeds. The six major breeds being produced in South Dakota are Berkshire, Chester White, Duroc, Hampshire, Poland China, and Spotted Poland China. The Yorkshire, Minnesota Number One and the Hereford breeds are present in much smaller numbers.
