Consider the life of a pregnant sow. Her incredible fertility is the source of her particular hell. While a cow will give birth to only a single calf at a time, the modern factory sow will birth, nurse, and raise an average of nearly nine piglets — a number that has been increased annually by industry breeders. She will invariably be kept pregnant as much as possible, which will prove to be the majority of her life. When she is approaching her due date, drugs to induce labor may be administered to make the timing more convenient for the farmer. After her piglets are weaned, a hormone injection makes the sow rapidly “cycle” so that she will be ready to be artificially inseminated again in only three weeks. Four out of five times a sow will spend the sixteen weeks of her pregnancy confined in a “gestation crate” so small that she will not be able to turn around. Her bone density will decrease because of the lack of movement. She will be given no bedding and often will develop quarter-sized, blackened, pus-filled sores from chafing in the crate. (In one undercover investigation in Nebraska, pregnant pigs with multiple open sores on their faces, heads, shoulders, backs, and legs — some as large as a fist — were videotaped. A worker at the farm commented, “They all have sores. . . . There’s hardly a pig in there who doesn’t have a sore.”) More serious and pervasive is the suffering caused by boredom and isolation and the thwarting of the sow’s powerful urge to prepare for her coming piglets. In nature, she would spend much of her time before giving birth foraging and ultimately would build a nest of grass, leaves, or straw. To avoid excessive weight gain and to further reduce feed costs, the crated sow will be feed restricted and often hungry. Pigs also have an inborn tendency to use separate areas for sleeping and defecating that is totally thwarted in confinement. The pregnant pigs, like most all pigs in industrial systems, must lie or step in their excrement to force it through the slatted floor. The industry defends such confinement by arguing that it helps control and manage animals better, but the system makes good welfare practices more difficult because lame and diseased animals are almost impossible to identify when no animals are allowed to move.
