Horses that are stabled under confined conditions may develop stereotypies (e.g. stall-walking), which may be caused by the inability of horses to express foraging behaviour. The objective of this study was to determine whether horses will use a foraging device (modified version of the ‘Edinburgh Foodball,’ British Patent No. 9200499.3) and if so, whether it has an effect on their overall time budget. The Foodball comprised a cylinder shaped casing with a food dispensing hole and an internal food store. Five Standardbred, individually stabled horses were subjected to the following three consecutive test periods as follows. Baseline (B): the animals were observed in their stable under normal management practises for three consecutive days; Foodball (F): for the following five consecutive days the Foodball, containing 4 kg of a high fibre pelleted diet was introduced to the horse and was refilled morning and evening; and Post enrichment (P): for the following three consecutive days the Foodball was removed from the stable. The horses were video recorded between 19:00 h and 12:00 h for the duration of the experimental period (allowing the horses outside for 7 h per day in order to allow exercising and grazing) and behavioural data were collected by time sampling every 2 min
