““Olsen et al. (2001) reported that [growing/fattening] pigs [used] the wallow for lying with temperature

ranges from -4 to 24°C [where temperatures exceeded 18C at only 5% of observations], with

increased use duration when temperature exceeded 15C. …Olsen et al (2001) also noted that pigs

kept dunging areas away from the roughage and lying area, and placed approximately 50% of their

dung in the wallow, supporting the theory that pigs prefer to dung in light, draughty and wet places,

and that they keep dung away from their nest and food” (Rachuonyo, 2001).

Wallows are available at all temperatures, certainly as of 15C (Olsen et al., 2001).

Dunging is allowed near the wallow

“Olsen (2000) showed that oral behaviour towards wallow water was positively correlated with

temperature. This behaviour consisted of rooting, chewing, making bubbles and having the snout
