What kind of animal is a mini pig? We will explain its characteristics, ecology, and habitat. This pig is not a wild animal, but a species that has been bred for captivity. They love to dig in the soil with their noses and are very vocal, so if you are not careful when raising them, you will receive complaints if you do not choose the right place.
What is a miniature pig? Basic status
Miniature pigs are a breed of pigs that have been bred as pets or experimental animals. They are called miniature pigs or mini-pigs in English, and have been bred by humans.

They are cheap, but it’s good to know about them.

Miniature pig definition
There are no regulations for miniature pigs. However, according to the American Miniature Pig Association (AMPA), a miniature pig is defined as one that is less than 20 inches (≒ 50 centimeters) tall at the front shoulder when mature. In general, miniature pigs are smaller than domestic pigs that weigh over 200 kilograms. The Gottingen and Vietnamese potbellies are famous.
Micropig definition
Micropigs are defined as pigs that are even smaller than minipigs. Micropigs often refer to pigs with a size and weight of 12 to 40 kg. Minipigs grow to 40 to 80 kg, so pigs smaller than this are defined as micropigs.
Originating from Vietnam
Most minipigs kept as pets in the United States, the United Kingdom, Germany, Japan, etc. originate from Vietnam. Micropigs also originate from Vietnam, as they were created by mating particularly small Vietnamese pot-bellied pigs.
Different restrictions than pure pets
These miniature and micro pigs are subject to laws and regulations for managing livestock. Therefore, they are subject to many restrictions due to legal regulations. Information has shown that disease prevention and movement management similar to those for farming are highly mandatory, and this is a mandatory requirement in most developed countries. Owners need to not only be smart, but also follow the rules and laws.
About Mini Pig Living Environment
Mini pigs are a domesticated breed of pig and do not live in the wild. This means that they have no concept of a “natural habitat” and primarily live in captivity. The following summarizes their habitat:
Living Environment
Home

Cages and exercise space are required
Farms and breeder facilities
Kept in breeding facilities for experiments and pets
Parks and facilities
They are sometimes kept at animal care facilities and tourist ranches.
Living Space Characteristics
Temperature control is required
They are sensitive to extreme cold and heat, and an indoor temperature of 20-28°C is ideal.
Exercise space is required
Insufficient exercise through walks and play can lead to obesity and health problems.
Social life in a safe place
Interaction with other mini pigs and owners is important
Differences from Wild Pigs
Mini pigs are not feral, so they do not live in natural forests or grasslands.
Their habitat is completely dependent on artificial and controlled environments.

Living Environment

Temperature Control is Important: They are sensitive to cold and heat, with temperatures between 20-28°C (68-88°F) being ideal.

Gestation Period: Approximately 114 days (approximately 3.5 months).
Birthing: They give birth to 3-8 piglets at a time.
Raising: The mother pig provides nursing and protection. In captivity, they are cared for by caretakers.
Behavior and Sociality
Primary gregariousness: They tolerate loneliness poorly and need interaction with other animals and people even in captivity.

Can they be kept as pets?
Mini pigs and micro pigs can be kept as pets. Please pay attention to the following points when raising them. There are many reports and consultations about health problems if you are not careful when raising them. Be careful when feeding them. Check what they eat and the environment. Be sure to consult with your family and decide on the species you will raise. They are loud, so they may be a nuisance to your neighbors.
How to buy
Compared to other breeds, individual burmese are rarely seen for sale at general pet shops. To purchase either species, it will cost about 100,000 to 500,000 yen in Japanese yen. Compared to large dogs, there are few of them, so they seem to be a little expensive. Prices are generally on the cheaper side, so they are not difficult to find. They are highly intelligent from birth, and although they are laid-back, they are easy to raise.
If you need a cage, buy one
There are no cages specifically for pigs, so it is better to buy one for dogs and get them used to being in one. Pigs also like to dig their noses and have the habit of digging various things with their noses, so create an environment where they can “dig their noses”. They also don’t have much of a smell. They have little body hair and no sweat glands, so you don’t have to worry about animal odor.
Costs required for raising
Monthly expenses are food and toilet. Their staple food is vegetables and pellets. You will probably spend about 10,000 to 20,000 yen on pellets and toilet sheets. A hospital is not necessary, but you will need to live near a veterinarian. All hospital fees are at actual cost, so if your pig is prone to illness, there is a risk of high expenses.
You can take measures to train them
Mini pigs and micro pigs are intelligent. Therefore, we recommend raising them as young as possible. If you educate them properly, they will learn to use the toilet and learn tricks to get used to people, so they are recommended for beginners. They have a gentle personality and are very expressive, so it is fun to raise them.
How long do pigs live?
Pigs are said to have a lifespan of 10 to 15 years. However, if you do not pay attention to hygiene, they may end up being short-lived. Even though they are animals born for experiments, you should have them checked regularly. They are considered to be relatively knowledgeable and intelligent, and because they are cute, it is recommended to keep them indoors together with rabbits. They are less maintenance-intensive than medium-sized dogs or wild boars, so some people nowadays walk them on small harnesses.
