While you can buy bags of premixed pig food at most farm supply stores, you might want to make your own pig food mix. Many people believe that you can feed pigs anything, such as your table scraps and whatever else you can get your hands on. While it's true that pigs will eat just about anything, they should be fed a balanced diet just like any other animal. This is especially true if you are raising your pigs commercially, as you want them to be as healthy as possible.
Feed your weaners, or pigs that are being weaned off of their mother's milk, a special mix of food until they are about 10 to 12 weeks old. Create a feed mix that is comprised of about 76 percent corn or wheat, 12 percent skim milk powder, 6 percent soybean meal, 6 percent calcium and protein supplement, and 0.2 percent salt.
Begin feeding your pigs a grower diet when they are about 12 weeks old. Create a feed mix that is 79 percent sorghum, 10 percent soybean meal, 7 percent calcium and protein supplement, 4 percent sunflower or peanut meal, and 0.25 percent salt.
Feed your breeder pigs a different mix than the rest of your pigs. Make a feed mix that is 80 percent sorghum, 10 percent sunflower meal, 10 percent calcium and protein supplement, and 0.25 percent salt.
