The term for a swine giving birth is "farrowing." A female pig, known as a sow, typically gives birth to a litter of piglets after a gestation period of about 114 days. During farrowing, the sow will usually deliver between 6 to 12 piglets, although larger litters can occur. This process is crucial for swine production in farming and affects the overall health and welfare of both the sow and her piglets.
