PDS is characterized by any of the following: low milk production, anorexia (off-feed), fever, mastitis, and uterine infections; however, some females may not show obvious clinical signs other than producing piglets with below average weaning weights. PDS can be caused by changes in sow/gilt body composition and metabolism, response to stress in the environment, and the presence of infectious agents.
