What does farrowing mean?
Farrowing is the term used in agriculture and veterinary medicine for the act of a sow giving birth to a litter of piglets. A single gestation typically produces eight to fourteen piglets after roughly three months, three weeks, and three days — a duration so well known among farmers that it is remembered as the 'rule of threes.' Because newborn piglets are vulnerable to being crushed and to cold, farrowing is managed closely on commercial farms: sows are commonly moved into farrowing pens or crates shortly before birth so that staff can monitor labour, provide heat lamps, and safeguard the litter. The word derives from the older noun 'farrow,' meaning a litter of pigs, which itself comes from Old English and is related to Germanic words for young animals. Though narrow in scope, farrowing is indispensable vocabulary for anyone working with pigs.

"The farm installed new heat lamps in the farrowing pens ahead of the spring litters."
"Good ventilation in the farrowing house reduces piglet mortality during the first critical days."
"The sow became restless and began nesting behaviour, a sure sign that farrowing was imminent."
On modern pig farms, sows often give birth in specially designed 'farrowing crates' — and the word itself traces back over a thousand years to Old English.

Etymology of farrowing
The word descends from "farrow," an Old English noun meaning a litter of pigs, which in turn stems from Germanic roots associated with young swine; its Germanic pedigree links it to cognate terms in other West Germanic languages such as German "Ferkeleln/Ferkel" territory of pig-related vocabulary. The verb "farrow," meaning to give birth to piglets, developed from this noun by the late medieval period, and the gerund form "farrowing" became standard agricultural usage.
