Ítem Acceso Abierto Concentración de cortisol como bioindicador de bienestar animal en la manada equina expuesta a estímulos sociales(Universidad Católica de Cuenca., 2025) Padrón Pesantez, María Eulalia; Maldonado Cornejo, Manuel Esteban; 0150175420Equines are highly sensitive to stress, meaning that any activity around them can trigger a release of plasma cortisol, thus impacting their well-being. Research on this subject has primarily focused on the utilitarian aspect of these animals, which often involves exploiting them beyond their natural capacities and consequently compromising their health. This study aimed to determine serum cortisol levels using the quantitative ELISA (Accubind) technique in a herd of horses used for equine-assisted therapy, compared to a stable group at the same location, measured at different times of the day as a bioindicator of animal welfare. For this purpose, eight castrated male horses from the same herd were selected, with four participating in equine therapy (experimental group) and four not (control group). Blood samples were drawn twice daily over five different days, resulting in a total of 80 samples. The cortisol range in the experimental group was 10.97 ± 5.73 μg/dL, while in the control group, it was 9.03 ± 3.99 μg/dL (p≥0.05). A significant difference was found between groups when comparing the interaction of circadian rhythm (morning and afternoon) (p<0.05). Horses in the control (10.21 μg/dL) and therapy groups (11.94 μg/dL) began with similar values; however, the control group showed a decrease (7.84 μg/dL) in cortisol levels by the end of the day, unlike the therapy group (9.99 μg/dL). These results indicate that equine therapy affects cortisol levels, possibly due to the physical effort involved, which may disrupt the animals' circadian rhythm.

Nine adult female dogs from different family groups were selected and exposed to various odoriferous stimuli (their own urine, unfamiliar urine, collar, and an item of clothing belonging to their guardian) with the aim of analyzing their ability for individual and affiliative discrimination. In order to accomplish this, the nine dogs were assessed in a controlled setting across nine different sessions, during which they were exposed to the various stimuli hidden under a cone. The frequency and intensity of their approach to each stimulus were recorded and analyzed. The results revealed a marked preference for their own urine and their guardian’s clothing, highlighting a socio-emotional function of the olfactory system in self-identity recognition and family bonding. Although not all stimuli elicited consistent responses—such as the collar—the observed behavioral patterns support the presence of a functional olfactory self-recognition ability in dogs, with direct implications for their welfare in both clinical and social contexts. It is concluded that the sense of smell constitutes a key sensory pathway in the construction of social bonds and in the perception of the “self,” and its integration into handling strategies and environmental enrichment in veterinary medicine is recommended.
