| Resumen: |
The recognition of animals as sentient beings has raised societal awareness of the welfare of farmed animals. This has been instrumental in increasing the legislative pressure towards welfare-conscious farming practices and, more lately, greater consumer demand for ethically sourced products. Besides, improved animal welfare is a key driver for enhanced performance, particularly in breeding boars, as welfare conditions strongly influence reproductive outcomes. The stressors associated with confinement impact testicular physiology and semen quality and the efforts to improve the welfare of breeding boars have so far focused on mitigating the negative consequences associated with stressors. The Five Freedoms framework and the European Food Safety Authority (EFSA)'s 'welfare consequences' approach prioritise the alleviation of suffering. In breeding boars, key welfare negative consequences include movement restriction, isolation stress, inability to engage in exploratory behaviours, locomotory disorders, and prolonged hunger. The negative consequences, which can be mitigated by improved housing and management practices, should be tackled in any commitment to improve the welfare of breeding boars. Animal welfare science, however, has recently shifted towards cultivating positive welfare experiences and a life worth living, beyond just alleviating suffering. The Five Domain Model systematically evaluates animal welfare, considering both negative and positive aspects. Encouraging positive welfare states involves facilitating species-specific behaviours, such as exploration and play, and fostering positive human-animal interactions. In breeding boars, strategies promoting positive welfare include providing enriching environments, encouraging exploration, and cultivating positive interactions with caretakers. Thus, for an overall welfare improvement of breeding boars, not only should the absence of suffering be guaranteed, but also the promotion of positive experiences that make their lifes worth living. |
