Livestock, farm animals, with the exception of poultry. In Western countries the category encompasses primarily cattle, sheep, pigs, goats, horses, donkeys, and mules; other animals, such as buffalo, oxen, or camels, may predominate in the agriculture of other areas. So, the short and sweet answer is, for a good feeder pig, expect to pay from $60-$100 depending on age and breed. For breeding pigs of good quality and genetically sound bloodlines, expect to pay somewhere between $300-$1000. Keep in mind that some of these pigs sell at shows for thousands of dollars.It is not uncommon to see photos of newborn piglets that are advertised as 2-4 months old. The pigs advertised from these breeders typically cost $700-$1,500, and most breeders require a $100-$250 deposit on the piglets. Reputable breeders can often be found through professional potbellied organizations.
