A baby pig is called a "piglet." Piglets are born after a gestation period of around 114 days and typically weigh about 2-3 pounds at birth. They are characterized by their small size, short legs, and cutely round features. Piglets are highly social animals and tend to form close bonds with their littermates. After weaning, which occurs at about three to four weeks of age, piglets transition to solid food and continue growing rapidly. Piglets are not only important in agriculture for breeding and meat production, but they also capture the hearts of many due to their playful and intelligent behavior.
