Weaning and other common production practices may have negative consequences on pig health and performance. Many physical aspects of a pig’s environment also may impact its overall well-being.
In the meantime, it may be worth exposing pigs in confinement facilities to more lighting than they currently receive. At least make sure that light intensity is consistent across the entire barn. For example, the level should be more than 50 lux (like a bright, clear day) at the pig’s eye level.
