Forages such as grass or grass hay should be available to pet pigs at all times. Eating grass and hay promotes healthy digestion in pigs, from helping to wear their teeth down properly to preventing gastric ulcers. Bermuda hay and Timothy hay are healthy choices for potbellied pigs. Alfalfa hay is too rich in calories for most pet pigs. If your pig has never eaten hay before, you can encourage consumption by wetting hay with a small amount of apple juice or other fruit juice. Discard any wet, uneaten hay daily to prevent molding.
Potbellied pigs and other miniature pigs should be fed a commercial pelleted diet designed specifically for their nutritional needs. Pet pigs should not be fed sweet feed or other grains, or feeds designed for “show pigs” or hogs. Potbellied pig feeds should be fed according to label recommendations, based on the ideal healthy weight of the pig. The daily serving of pellets should be divided up into at least 2 meals per day. Do not starve growing pet pigs in an attempt to make them stay small. This practice will lead to developmental disorders and an unhealthy pig. Overfeeding pigs will lead to obesity and related diseases such as arthritis.
Treats should be fed sparingly and should make up less than 5-10% of the diet. Pet pigs are not garbage disposals- do no feed them your leftovers! However, treats are very helpful in training and socializing pet pigs, so it is important to have healthy options available. Leafy greens and other fresh vegetables can be fed daily. Fruits and fruit juices should be fed less frequently due to their high sugar contents. On special occasions, pigs can enjoy dog biscuits, pretzels, unbuttered popcorn or a dry cereal low in sugar.
All pigs should have access to fresh, clean water at all times.
