“…and the lowest for stabled horses (mean 35.2% ± 13.5%), which may be due to stabling occurring predominantly overnight (except during heat periods) when horses eat the least, lower food availability in the stable, palatability of grass versus hay and the variable caloric density of the accessible food. Given the caloric requirements of 16.7 Mcal/day/500 kg horse at rest and the average caloric density and dry matter (DM) proportion of pasture (2.23 Mcal/kg DM, 30% DM) and grass hay (1.78 Mcal/kg DM, 90% DM), a 500 kg horse needs to consume 25 kg grass or 10.3 kg hay, with correspondingly different required feeding times, to cover its caloric requirements [47][48][49][50]. However, food intake is controlled not just by energyrelated homeostatic signals but also somatosensory and motivational stimuli, explaining why diet has the greatest effect on equine time budgets [10,51].…”

Housing and management conditions strongly influence the health, welfare and behaviour of horses. Consequently, objective and quantifiable comparisons between domestic environments and their influence on different equine demographics are needed to establish evidence-based criteria to assess and optimize horse welfare. Therefore, the present study aimed to measure and compare the time budgets (=percentage of time spent on specific activities) of horses with chronic orthopaedic disease and geriatric (≥20 years) horses living in different husbandry systems using an automated tracking device. Horses spent 42% (range 38.3–44.8%) of their day eating, 39% (range 36.87–44.9%) resting, and 19% (range 17–20.4%) in movement, demonstrating that geriatric horses and horses suffering from chronic orthopaedic disease can exhibit behaviour time budgets equivalent to healthy controls. Time budget analysis revealed significant differences between farms, turn-out conditions and time of day, and could identify potential areas for improvement. Horses living in open-air group housing on a paddock had a more uniform temporal distribution of feeding and movement activities with less pronounced peaks compared to horses living in more restricted husbandry systems.
