Introduction • Horses kept in paddocks can be considered close to a feral activity behaviour ? • Free moviment is important for domesticated horses: • to lower the incidence of behavioural troubles • to improve the gut’s general health • Free activity affect the overall requirements of an horse taken into account while rationing C.

Introduction • The aim of the work is: • to state if a GPS device is useful to study horses kept in paddocks • to obtain preliminary results in diurnal observations C. Amato, E. Valle, D. Bergero Druento (To), 31oct - 01 nov 2008
Materials • Haflinger and Bardigiano horses(1-9 years) • Garmin Forerunner 201 GPS device • Forerunner Logbook software • ANOVA C. Amato, E. Valle, D. Bergero Druento (To), 31oct - 01 nov 2008

Methods • 129 observations of the diurnal free activity • Measured data: total Km, gallop occurrence, trot occurrence, speed (average, max), registration time • Collected data: breed, sex, age, feeding habits, weather conditions, temperature, presence of the stallion, number of the horses in the group, presence of people, paddocks width (3000 to 20000 m²).

Results C. Amato, E. Valle, D. Bergero Druento (To), 31oct - 01 nov 2008
Results • Mean time observation: 8 h • Total distance covered (KMT): mean 2.04 km (1.47 km sd) • Gallop occurrence (NG): 1.85 (1,33 sd) • Trot occurrence (NT): 8.96 (7.33 sd) • VMED: 0.25 km/h (0.17 km/h sd) • VMAX: 18.66 km/h (9.48 km/h sd) C. Amato, E. Valle, D. Bergero Druento (To), 31oct - 01 nov 2008
Results • Breed → VMED, NT, NG • Bardigiani move more than Avelignesi • Sex → KMT, VMED, NT, VMAX • Mares move less than geldings and stallions • Age → VMED, NT, NG • Higher values for horses aged 4-7 years C. Amato, E. Valle, D. Bergero Druento (To), 31oct - 01 nov 2008
Results • Presence of the stallion → NT • The presence of the stallion increases NT • Number of horses → VMED, NT, NG • The highest values are in larger groups (> 8 horses) C. Amato, E. Valle, D. Bergero Druento (To), 31oct - 01 nov 2008
Results • Temperature → NT • Temperature between 15 º and 20 º increases the values • Wheather condition → No difference • Presence of people → NT in presence of people the horses move less C. Amato, E. Valle, D. Bergero Druento (To), 31oct - 01 nov 2008
Discussion • Horses in paddocks perform very little spontaneous movement • Different factors affect diurnal physical activity • GPS give useful information on the behaviour and requirements of horses kept in paddocks C. Amato, E. Valle, D. Bergero Druento (To), 31oct - 01 nov 2008
