Hog farmer Kenny, from the RM of Springfield in Manitoba, shared this video in July 2018, showing weanling pigs at about seven to eight weeks of age in a nursery barn. The nursery barn is warm and protected from drafts, with fresh air circulating all the time. These group pens can contain as few as 10 or as many as 300 pigs. As you can see, the weanlings socialize well, including running, playing and nosing each other. Weanlings stay in this barn for up to eight weeks, during which time they grow to about 26-30 kg (57-66 lb), and are then moved to a feeder barn.
