How Heavy Is a Boar? Average Weight & Influencing Factors

A boar refers to a wild pig, specifically a wild member of the species Sus scrofa, which is the ancestor of most domestic pigs. These animals are found across a wide range of habitats globally, distinguishing them from their domesticated counterparts. Understanding their weight involves examining typical ranges and the biological and environmental factors that contribute to their diverse sizes.

Typical Weight Ranges

The weight of boars varies considerably by geographic location and subspecies. In most of Europe, mature male boars typically weigh between 75 and 100 kilograms (165-220 pounds), while females average 60 to 80 kilograms (130-180 pounds). Males in Europe’s Mediterranean regions may be as light as 50 kilograms (110 pounds), with females around 45 kilograms (99 pounds).

Larger European boars are found in more productive areas, such as Eastern Europe, where males can reach 110-130 kilograms (240-290 pounds) and females about 95 kilograms (209 pounds). In Central and Western Europe, some males can weigh up to 200 kilograms (440 pounds), and females up to 120 kilograms (260 pounds). Asian wild boars also show significant size variation; males in Northeastern Asia can grow to 270-350 kilograms (600-770 pounds), and the Ussuri boar, a large subspecies, can weigh up to 350 kilograms (770 pounds).

Feral hogs in North America, often descended from domestic pigs or their crosses with wild boars, average around 82 kilograms (180 pounds). Adult males generally weigh 90-100 kilograms (200-220 pounds), and females range from 68-77 kilograms (150-170 pounds).

Factors Influencing Size

Several biological and environmental factors contribute to the wide range of weights in boar populations.

The specific subspecies plays a significant role, as different types of wild pigs possess different average sizes. For example, the Ussuri boar is large, while the Japanese boar is smaller.

Age is another important determinant; younger boars weigh less than mature adults. Piglets typically weigh only around 0.6 to 1 kilogram (1.3-2.2 pounds) at birth. They experience rapid growth, with yearlings averaging around 54 kilograms (120 pounds) for both sexes, and individuals older than two or three years generally reaching full adult size.

Sex also influences size, with males generally being larger and heavier than females. Males can be 5-10% larger and 20-30% heavier, with this size difference becoming more pronounced as the animals age.

Diet and nutrition impact boar growth and overall body mass. The availability and quality of food directly affect their weight gain and fat reserves. Boars in areas with abundant food, such as agricultural crops, tend to be heavier than those in less productive environments. Increased access to cereals and root crops can significantly boost body weight.

Habitat and climate also affect boar size. Boars in arid regions with limited food and water tend to be smaller, while those in productive areas with ample resources grow larger. Climatic conditions, including temperature and precipitation, can influence body weight, with favorable conditions supporting greater growth. Genetics also contribute to an individual’s potential for growth, interacting with environmental conditions to determine ultimate size.

Exceptional and Record Weights

While typical boar weights fall within established ranges, some individuals achieve remarkable sizes. The largest wild boars recorded often significantly exceed average weights.

One well-known example is “Hogzilla,” a wild hog from Georgia initially rumored to be over 450 kilograms (1,000 pounds), though later verified at around 360 kilograms (800 pounds) and 2.4 meters (8 feet) long.

Another notable case is the “Coursey Hog,” an 1,100-pound (500-kilogram) feral hog documented in Georgia, representing one of the largest recorded in the United States. In California, a 733.5-pound (332.7-kilogram) hog was taken, setting a state record.

These exceptional weights are rare and occur in areas with abundant food sources, allowing individuals to reach their full growth potential.
