Leptospira in Working Horses From Rural Ecuador: A Neglected Occupational Risk. Neglected tropical zoonotic diseases such as leptospirosis continue to have a significant impact on animal and human health, especially in low-income countries due to limitations in surveillance and knowledge gaps to guide mitigation. In this context, equines have the potential to play an important role in the maintenance and transmission of spp. due to their susceptibility to a variety of serovars (often without signs of disease) and close contact with humans. To better understand the epidemiological role of horses, we evaluated exposure and identified circulating leptospires by collecting b...
Placental adaptation to maternal environment in domestic animals. The developmental origins of health and disease (DOHaD) is based on the observation that environmental conditions during sensitive windows of development shape lifelong physiology and disease susceptibility. While fetal organs are often viewed as direct programming targets, the placenta is a crucial mechanistic hub because it senses maternal conditions and actively constructs the fetal environment through nutrient transport, endocrine signaling, and immune regulation. Placental plasticity spans morphology and how exchanges are favored by tissue topology, vascular development and perfusion, tra...

Estimating the economic value of working donkeys in Ethiopia. There is limited empirical evidence on the quantitative economic contribution of donkeys to livelihoods, leading to their undervaluation and exclusion from policy. Here an enterprise budget analysis is embedded within a stochastic dynamic population model for three production systems in Ethiopia to evaluate system inputs, outputs and the economic contribution of donkeys. The model was parameterised using data from household surveys, focus group discussions and key informant interviews, supplemented by literature. The economic value of donkeys' (unpaid) homestead and agricultural services was e...
Open habitats and species differences shape space use in semi-feral cattle and horses across Danish rewilding sites. Large herbivores can strongly influence ecosystem structure and biodiversity, making knowledge of their space use important for trophic rewilding. We used GPS-tracking data collected over two years from 10 semi-feral cattle and 17 horses across ten Danish rewilding sites to analyse habitat use in a use-availability framework using resource selection functions (RSFs), complemented by direct behavioural observations. Both species showed large individual variability but overall used habitats disproportionately to availability, with higher relative use of open habitats; including dry grassland and...
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 assessm...
