A feral pig is nothing more than a domestic that has gone wild. The diffrent colors are a result of cross breeding either in the wild, or selective breeding by a producer to produce an animal for a specific purpose, such as more bacon, bigger hams, etc. There are approximately 90 recognized breeds worldwide, and eight major breeds in the US. The colors are basicly white, red, black and white. Cross breeding produces pigs of all colors combinations. The razorback is likely the oldest breed in America, and is not of the eight recognized breeds, but has inter-bred with domestic and produced another line. The razorback has also been bred to the Russian and released all over for the hunters. In many of the Southern states there is a Piney Woods Rooter, a long snout pig that is simular in size and temperment to the razorback. They are mostly wild, and what a lot of the folks down south hunt. But they have also inter-bred with domestic hogs that have gone wild.
Most of the pigs you see here in Texas are nothing more than a domestic that has gone wild, or feral. I hate to admit it, but my partner and I contributed to the problem several years ago. We set out on a venture to raise pigs, had over 100 in a pen on the farm near Noodle, Tx. The bottm fell out of the pig market, we couldn't give a pig away. During this period we were having to buy feed for an animal that we though would never show us a return of investment, when they got out of the pen we didn't try to catch them, it was a blessing since we no longer had to feed them. So likely, what you are hunting today may be an off-spring from one that excaped our pens in the 1980-81 time frame. Our pigs were Duroc (Red) and Berkshire (Black with white points)
