To cook a whole pig in a rotisserie, place the meat into the unit, making sure it's at least 12 inches away from the heat source. Set the rotisserie heat temperature following pig roasting temperature guidelines, and cook the meat for the number of hours recommended.
When positioning the pig in the rotisserie, it's important to distribute the weight of the pig as evenly as possible. Heat from the rotisserie must remain at a constant level for best results. Roasting a pig requires constantly checking the meat during the cooking process. Estimated cooking times for roasting a pig are guidelines, and the actual cooking times vary. Use a meat thermometer to check the pig's internal temperature, and once it reaches 160 degrees Fahrenheit, remove the pig from the heat.
Generally, a 75-pound pig requires six to seven hours of cooking time. A pig weighing 100 pounds cooks in approximately seven to eight hours, and a 125-pound pig needs between eight and nine hours of cooking time.
A fully cooked pig can stay warm for one to two hours before it dries out, so plan to serve it within that time range. Cleanliness is a high priority when handling an uncooked whole pig. Prevent bacteria from growing on the pig by wiping it with a cloth soaked in heavily salted water, and keep it cold until ready to cook.
