Occasionally they are mentioned as being mini juliana or mini painted pigs. This breed should always be spotted, BOTH parents must be spotted and have documented lineage. Pure breds julianis are very, very, very rare.
They are one of the oldest breeds of pigs. The breed has been endangered many times. This breed has been bred and trained as research and rescue pigs. They were imported from Europe for the pet industry. Please beware of cross bred animals. Many times people who can not find or afford a breeding pair will cross breed them with potbellies to try to produce more colorful pigs. All piglets in a litter as well as the parents should be spotted. Spots can be on the skin or hair. If you run across a breeder advertising a "juliana/juliani piglet" and it is a solid color - run the other way. They do not know what they are doing and have no business breeding miniature pigs. A good breeder is an educated breeder & an educated breeder knows what they have as far as genetics, bloodlines, etc. 90% of miniature pig breeders today can not even tell you what breed of pig they are producing.
Mini pigs are not pot bellies. Mini pigs were not bred down from pot bellies. They are two completely different breeds. The mini pig is not a juliani pig. Mini pigs were created by the medical research companies not to market as pets, but to create a smaller swine model for their research. They have been a vital part of learning and benifital to gun shot and burn victims, diabetics, heart disease and transplants, dietary advances, and genetics. Many people who can not find or afford these pigs will cross them with potbellies to try and get a smaller pig, please be careful. Pure bred pigs are rare and hard to find. We will typically cross breed the juliani pig and the mini pig to obtain the small size and personality of the juliani pig. Most people find the "deer like" appearance of the juliani undesireable, yet they want the tiny size. The mini pig has a short, squared off snout, tiny short legs and a "box like" body. Most piglets, other than color, look alike as babies. A good breeder will be able to tell you after the first two weeks (after birth) which piglets will display certain traits.
