Manitoba, Ontario and Quebec are the largest pig-producing and pig-slaughtering provinces in Canada. Approximately one-quarter of all Canadian pigs are exported to the U.S. for fattening and slaughter.
Typically, a sow has about 2.2 pregnancies a year, producing 19 to 22 pigs annually. A sow has an average of only three litters before her productivity wanes and she is sent to slaughter at an age of 24 to 30 months. Sows that are no longer productive are termed “cull sows.” Due to prolonged confinement, lack of exercise and the fact that pigs have been bred for large size, culls sows often experience lameness, foot injuries, weakened bones and painful abrasions. When sent to slaughter, pigs that have difficulty walking or navigating the transport ramps are too often roughly handled and outright abused. Electric prods, despite being discouraged by animal welfare scientists, are over-used, causing pigs to go down (“downers” are animals that are unable to stand or walk).
