26 piglets aged 1 week were used to study the effects of dark and shadows on their behavioral responses. In the first test, piglets were held in an enclosure, then allowed access to a like-sized adjacent enclosure. The piglets significantly feared staying in dark. Provision of the light beam significantly enhanced the piglets' movement into a dark area. The spot light and painted black and white patterns on the floor had a tendency to frighten the piglets. It is suggested that piglets have a tendency to move towards a more brightly illuminated area and that they negatively respond to sharp contrast of black and white on the floor.
