The heaviest hog that was ever recorded in history weighed 2,552 pounds and was called Big Bill. The meat of a pig, the pork, provides thiamine, B-vitamins and proteins in a diet. The content of thiamine in pork is three times as much as it is in other types of foods and it converts carbohydrates into energy and boosts a healthy appetite. Pigs also provide up to 40 types of medicines including insulin. In fact, their heart valves are used to restore damaged heart valves of human beings.

Domestic pigs are descended mainly from the wild boar (Sus scrofa) and the Sulawesi warty pig (Sus celebensis), diverging from their closest ancestors about 500,000 years ago according to the Encyclopedia of Life. Currently there are approximately 752 million domestic pigs worldwide, 406 million of which can be found in China, according to Statista. 

In the last couple decades, lean growth and feed efficiency have dramatically improved average pig weight for market. Productivity of the average pig farmer has increased, with pigs per litter and average market hog weights both increasing. A sure sign that a farrow-to-finish operation is successful is that pigs remain profitable at heavier market weights.

How Big Are Pigs?

Pigs usually weigh between 300 and 700 lbs. (140 and 300 kilograms), but domestic pigs are often bred to be heavier. The largest pig in history was a swine called Big Bill, who stood at 5 feet (1.52m) tall and weighed an impressive 2,552 lbs (1,157 kilograms), according to Guinness World Records. 

Wild pigs on the other hand vary greatly in size and weight. The largest boar is the giant forest hog (Hylochoerus meinertzhageni). Native to more than a dozen countries across Africa, it grows up to 6.6 feet (2 meters) long and measures 3.6 feet (1.1 metres) tall, according to the Encyclopedia of Life. Though it is rarely seen, video of the elusive beast was captured in June 2018 by ecologists in Uganda, National Geographic reported.

Where Do Boars Live?

Boars, pigs and hogs live all over the world, except for Antarctica, northern Africa and far northern Eurasia, according to the Encyclopedia of Life. For example, red river hogs (Potamochoerus porcus), also called bush pigs, are found in Africa; babirusas (Babyrousa babyrussa), or pig deer, are found in Indonesia; and Visayan warty pigs (Sus cebifrons) come from the Philippines. 

Wild pigs typically live in grasslands, wetlands, rain forests, savannas, scrublands and temperate forests. Whenever they have the chance, all pigs wallow in mud as it helps them to regulate their body temperature and discourages parasites.

What Do Pigs Eat?

Pigs, boars and hogs are omnivores and will eat just about anything. Wild boars, for example, fill the majority of their diet with roots, seeds, bulbs and green plants, according to the Woodland Trust, however as opportunistic feeders they will also chow down on invertebrates, carrion (decaying flesh) and even small mammals found on the forest floor. 

How Many Offspring Do Pigs Have?

Domestic pigs can breed throughout the year without any seasonal constraints. Once pregnant, female pigs, commonly called sows, carry a litter of around 10 piglets for approximately 114 days before giving birth, according to the animal welfare organisation Compassion in World Farming.  

Within the first six hours piglets suckle the “first milk”, also known as colostrum, which is jam-packed with nutrients and essential antibodies to build the piglet’s immune system. If the piglet drinks the first milk after 25 hours of being born their intestines will not be able to successfully absorb the antibodies in the milk, according to the Agriculture and Horticulture Development Board. 

So How Much Does A Pig Weigh?

Pigs will generally weigh anywhere from 300-700 pounds (136-317 kg). Some less and some heavier. Weights can widely vary depending on the type of pig, as well as whether it is raised as a domestic pig or commercial pig. The largest pig we know of currently is a hog named Reggie. He tips the scales at a world record 1,335 pounds (605.5 kg). That’s massive for a pig.

How Much Does A Fully Grown Hog Weigh?

The weight of fully grown male pigs, popularly known as boars, is greater than 500 pounds while the weight of fully grown female pigs, popularly known as sows, ranges between 300 and 500 pounds. At birth, the weight of pigs is approximately 2.5 pounds, while between 6 and 7 months, their weight ranges between 210 and 250 pounds.

How Much Do Baby Pigs Weigh?

Do Pigs Have Teeth?

Yes, pigs have teeth, and they need them to help meet their constant eating habits. Piglets are born with what they call “needle teeth”. They are smaller in size and located toward the front of the jaw. As the pig gets older, they develop canine, incisors, and molars, which help them crush food. They are powerful when used. So you don’t want to get your hand caught in their mouth.

They get this reputation from their need to stay cool by rolling around in the mud.

Conservation Status

Wild boars are not endangered, according to the International Union for Conservation of Nature’s (IUCN) Red List of Threatened Species. They are listed as “least concern” due to the wild pig’s “wide range, abundance, tolerance to habitat disturbance and presence in many protected areas.”
