Is it okay for the pigs to eat leftovers?

It depends on the type of leftovers and the quantity. Leftover vegetables and fruits are generally okay for pigs in small amounts, but processed foods, salty foods, and spoiled food should be avoided. Pigs should also not be given too much food, as this can lead to obesity and other health problems. It's always best to consult with a veterinarian or an expert on pig care to determine what types and quantities of food are appropriate for your pigs.
