Lifespan of a Micro Pig

In the 1980s, the first miniature potbellied pigs were imported from Asia. These aren't the same animals as micro pigs, which appeared in the first decade of the 21st century. The media portrays micro pigs as fashionable pets for the home, but veterinarians warn owners that these animals need the same amount of attention as a dog, although they're easy to house-train. Micro pigs have a lifespan of between 18 and 25 years.

  1. Vital Statistics

    • Micro pigs are so small that at birth they can fit in a tea cup, which is why some sellers refer to them as "tea cup pigs." On average, the micro pig weighs 9 oz. at birth and grows to its full size by its second birthday: The micro pig's height at full growth is between 10 and 15 inches, and its weight is usually between 25 and 55 pounds. Although the lifespan of these pigs can reach up to 25 years, the Miniature Pigs Guide website suggests that use of "nutritional manipulation" by certain breeders to produce micro pigs may result in pigs that only have a lifespan of three to four years. Other breeding and environmental issues may also affect the length of a micro pig's life.

    Breeding

    • Micro pigs are sometimes selectively bred from potbellied pigs and Gloucester Old Spot, a full-sized pig breed. Breeders choose the smallest pigs from each litter to create the next generation until the piglets are miniature versions of the original. Because breeders use piglets from the same litter in the process, there's a problem with inbreeding. This can lead to deformities, reduced fertility and the inability to have a litter. Issues like this are likely to shorten the animal's life as they weaken the pig overall.

    Environment and General Health

    • The Institute for Animal Health says that micro pigs are vulnerable to depression if they aren't suitably stimulated with toys, play and preferably the company of another pig. Physically, micro pigs are generally healthy, but they can get an intestinal blockage if they eat too much in one sitting. This can lead to serious illness or death for a micro pig. Like other pets, micro pigs need vaccinations and worming; they also require hoof care.

    Buying a Micro Pig

    • Veterinarian Pete Wedderburn advises that prospective owners only buy from responsible breeders, as there have been occasions where a micro pig has suddenly become a full-size pig after a few months. Breeders should keep the baby pigs until they're weaned, which is usually at around two months, and vaccinate and deworm the pigs before sale. A reputable breeder also supplies buyers with documentation, showing what treatments the animal has received to date. Buying from a responsible breeder can help ensure that a micro pig enjoys a healthy, long life.
