SwinePigs or hogs are also known as “pigs” or “hogs.” Actually, a pig is a young swine, and a hog is a mature swine that weighs more than 120 pounds.

A mature male swine is called a boar. If the male has been neutered, it is called a barrow. A barrow is unable to produce offspring.

A young female swine is called a gilt. After the female has given birth to a litter of piglets, she is called a sow.

Generally, 8 to 12 piglets make up a litter. Each piglet is about a foot long (12 inches) and weighs about 3 pounds at birth. A sow may give birth to five or more litters during her lifetime.

Swine are omnivoresPlant and meat eater and have a digestive system that is similar to that of humans. Pigs raised for market are fed a diet of ground oats, barley, corn, or soybeans. Vitamins and minerals are also added to the diet. It takes about 920 pounds of feed to get a hog ready for market.
