The brood sows are placed in separate pens at farrowing time and watched carefully when giving birth to the pigs.
One of the chief causes of trouble with the farrowing sow arises from the sow not having been allowed to take sufficient exercise.
In ordinary cases this is not necessary, the farrowing of a litter of pigs is a simple and natural operation.
All breeders lay great emphasis on the condition of the bowels during pregnancy, and particularly at farrowing.
Old English fearh "young pig," from Proto-Germanic *farkhaz "young pig" (cf. Middle Low German ferken, Dutch varken, both diminutives, Old High German farh, German Ferkel), from PIE *porkos- (see pork (n.)). Sense of "a litter of pigs" first recorded 1570s. As a verb, early 13c.
