Pot-bellied pigs generally have voracious appetites and will eat nearly anything that you offer them. Unfortunately, they are also very prone to obesity which can lead to foot and joint problems, as well as other health issues.
Packaged Diets for Pot Bellied Pigs
Pot-bellied pigs need a good quality diet that is high in fiber and low in calories.
Ideally, a food formulated specifically for pot-bellied pigs or mini pigs should be fed.
These special diets can now be found at some feed stores and pet stores. If your local store doesn’t carry these diets they may be able to order them in for you or you could also check to see if your veterinarian can order them.
As a basic rule in non-breeding adults, feed about 1/2 cup of maintenance food per 25 pounds of the pig’s weight (so a 75-pound pig would get 1 1/2 cups of food). The total amount should be divided into 2 meals a day. However, this amount is just a guideline and should be adjusted based on the pig’s body condition. If the pig is developing rolls of fat around their face and you have a hard time feeling their hip bones, your pig is becoming obese and should be fed less. Conversely, if the pig feels skinny you should feed more. Piglets up to 6 weeks of age can be fed the starter ration free choice (as much as they want) but from 6 weeks to 3 months of age gradually limit the starter food down to about 1 to 1 1/2 cups per day. Nearing 3 months of age, make the gradual change to the adult diet.
Fresh Foods for Pot Bellied Pigs
In addition to the formulated diet, you can feed a good variety of fresh vegetables to make up about 25% of your pot-bellied pig’s diet. Foods such as celery, cucumbers, peppers, carrots, potatoes, and some greens are good choices (but try to limit the starchy vegetables like potatoes). Some fruits can be feed as well but only in moderation due to the high natural sugar content. Most pigs love treats like apples, grapes, and raisins, but these are good to reserve as treats to be used in training (as they are very motivating). Extra fiber can be provided by feeding hay (e.g. alfalfa) and some experts recommend adding bran to whatever your pig eats.
Do Pot Bellied Pigs Graze on Grass?
Pigs should also be allowed the opportunity to root in soil and graze on grass (not treated with chemicals or fertilizer). Pigs are susceptible to selenium deficiency3 (since many pig owners do not give their pigs adequate grazing time) but in most areas, if they are allowed to graze and root in the soil they will get enough. If you live in an area with soil deficient in selenium you may need a mineral supplement. Check with your local pot-bellied pig veterinarian for advice on this.
