Differences between a boar, a hog, and a pig
The terms boar, hog, and pig all refer to different types of domestic swine and are used in various contexts to describe animals at different stages of growth, gender, and use. Understanding these differences is important for farmers, breeders, and animal enthusiasts.
Introduction
Swine are highly adaptable mammals that have been domesticated for thousands of years. Their classifications into boars, hogs, and pigs help specify their age, gender, and purpose. While these terms are sometimes used interchangeably by laypeople, they have distinct meanings in animal husbandry, veterinary medicine, and agriculture.
Pig: The General Term
The term "pig" is the most commonly used and generic term for a domesticated swine regardless of age, gender, or purpose. In everyday language, "pig" refers to the animal often seen on farms, in petting zoos, or as food products. Technically, a pig can refer to any swine juvenile or adult.
Young Pigs: The term is often used for juvenile swine before they reach maturity.
Adult Pigs: As adults, they are sometimes called hogs in agricultural contexts.
Hog: The Mature Swine
"Hog" is a term used primarily to denote an adult, particularly those raised for meat (pork). The term is widely used in American English and refers to mature swine that weigh over 120 pounds (55 kg). Hogs are usually slaughtered for pork production.
Hog Characteristics:
- Usually over 6 months old.
- Typically larger and heavier.
- Often raised in confinement systems.
- Used for commercial pork production.
Boar: The Male Swine
"Boar" specifically refers to an uncastrated male pig of breeding age. In breeding, boars are valued for their genetics and are often used for reproducing litters.
Boar Features:
- Un castrated male.
- Generally older than a piglet.
- Has distinctive physical features such as larger tusks and a more muscular build.
- Responsible for breeding with sows (female pigs).
Difference From Barrows: A castrated male pig is called a barrow.
