Farm Atmosphere: Calm Attention and Mobility Characterise Positive Horse Welfare.

On-farm welfare assessment of equines is a challenge given the large diversity of management practices, especially in terms of housing and activities. In our study, we tested time budget measures as a complementary tool to more conventional welfare indicators (e.g., stereotypic behaviours, ear position while foraging, neck shape). We observed 174 horses living in eight facilities (in their home environment) for which data on management practices and welfare were available. Time budget was assessed using the scan sampling method (1 min scan sampling over 30 min; 33 scans), while welfare assessment was based on classical measures. The study was performed in two parts: The first part consisted of validating time budget as a correlate of welfare state, which was performed at the individual level and according to the context of observation. In the second part, the data were analysed at the farm level by averaging data from all horses in the same facility. The results showed that the time spent feeding, in exploratory walking and observation behaviour were correlated with indicators of positive welfare and/or good practices in contrast to the time spent standing immobile resting or in fixed attention and/or in negative social interactions. Time budget varied greatly between facilities, reflecting welfare state and management (feeding, working) practices. This study shows that, provided that observations are made at different time periods when animals are calm, three sessions of 10 min. could give a good account of the local «atmosphere». These findings bring new insights into both methodological approaches and the significance of behaviours and, in particular, the importance of precisely defining and measuring the types of attention as a window into an animal's internal state.
