From Pig

The Hereford is a breed of pig first originated on the farm of R.U. Webber of La Plata, Missouri. Mr. Webber was said to have made his first crosses in about 1902, and these ultimately involved several breeds.

The advocates of the Hereford breed maintain that, although a relatively new breed, it is prepotent and breeds quite true in color pattern. It is stated in the association publications that at least 90 percent of the offspring of well marked Herefords carry acceptable color markings. The sows are prolific and good mothers and compare favorably in these respects with those of other breeds. Hereford hogs are fair grazers, good feeders and they fatten readily[2].
