. The objective of this study was to evaluate the inclusion of a brown seaweed additive (SWA; Macrocystis pyrifera ) in the diet of grass-fed steers on carcass performance, beef quality, and nutrient composition. A total of 20 Holstein-Friesian steers were randomly distributed into two groups: Control group (a basal diet without supplementation of SWA) and SWA group (2%-SWA) with basal diet + 30 g/day/animal of SWA during the breeding phase (11 months) and 48 g/day/animal of SWA during the fattening phase (4 months). Steers fed with 2%-SWA were not different ( P >0.05) in final body weight, carcass weight, carcass dressing, fat thickness, ribeye area, and marbling score than those from the Control group. Likewise, no effects of 2%-SWA supplementation were detected ( P >0.05) for beef quality traits, glycolytic potential, or their metabolites (muscular glycogen, glycose+glucose-6-phosphate, and lactate), evaluated in longissimus lumborum (LL) samples. Sensory evaluation showed a slight preference for Control group samples rather than those from the 2%-SWA group (58.93% and 41.07%; P =0.06). Regarding, proximal composition, the inclusion of SWA only affected the total lipids present in the LL samples, which decreased significantly ( P =0.01) in LL samples of grass-fed steers fed with 2%-SWA. The composition of macro (Ca, Na, Mg, P, and K) and micro (Mn, Fe, Cu, and Zn) minerals in LL samples were not affected ( P >0.05) by the inclusion of SWA in the diet. The inclusion of the additive based on brown seaweed had not a detrimental effect on carcass performance, beef quality, and mineral content, however, it reduced the total lipids content in the LL muscle.

The welfare of working equines is born of the relationship co-created with humans and the relational practices humans bring to this work. Our understanding of this relationship remains elusive, however, for it involves attending to that which arises both within and between the equine and the human. Attempts to study such relationships have, arguably, been confounded by the liminalities of relational practices, power literacy and the limitations of language, propositional knowing and the dualistic thinking that characterises many scientific disciplines. This paper presents the theoretical framework that underpins an experiential awarenessbased Action Research approach to transforming human-equine relations within the international mountain tourism industry. This approach privileges curiosity, compassion and primary or contemplative knowing and the development of self-awareness. Drawing on the work of Martin Buber on genuine dialogue and of Otto Scharmer on generative dialogue, this paper provides insights into what can arise in the between when attitudinal shifts are encouraged and facilitated that allow humans and equines to meet genuinely and be fully present to each other. This ultimately involves surrendering control, letting go, the dissolution of subject-object awareness and access to non-dualistic ways of knowing. An awareness of the importance of such shifts and of the source from which we operate is of fundamental importance to the realisation of the co-creative project that humans and equines can engage in. Failure to appreciate this distinction, arguably, leads and gives rise to relationships, whether human-to-human or human-to-horse, characterised by domination rather than partnering, absencing rather than presencing, by monologue rather than dialogue. The ethical and practical implications of this awareness are profound, with implications felt at the level of the individual, for whom the I deepens the more you pay attention, and at the level of the relationship, but also at the level of communities, whether these be constituted locally, nationally, internationally

. In recent decades, several articles have reported significant progress regarding pain treatment in veterinary medicine. This study aims to analyse the attitudes of veterinarians working in small animal practices in Uruguay towards the use of analgesics during the perioperative period. Veterinarians in charge of clinics performing surgeries were interviewed, including clinics located in the capital city, Montevideo (n=59) and the rest of the country (n=81), based on data obtained from the National Veterinary Census in 2010. Most interviews were conducted in person, and if not possible, they were carried out through video calls. According to gender, 54% of interviewees were women and 46% were men, with 95% of them practising in urban areas. The most used drugs were nonsteroidal anti-inflammatory drugs (NSAIDs), with dipyrone (89%) being the most popular. Amongst opioids, pure agonists presented minimal inclusion in analgesic treatment (13%), with tramadol (93%) being the most used opioid. Drugs belonging to other groups were less mentioned. Thirty-eight per cent of the respondents considered that their training in pain management was inadequate. Veterinarians categorised the intensity of pain caused by several surgical procedures as “severe”, however, they used weak opioids such as tramadol or NSAIDs as a single therapy to treat most cases. The scarce use of analgesic drugs and techniques that provide profound analgesia (such as mu-opioid receptor agonists) by Uruguayan veterinarians reveals the need for open discussion, adjustment of attitudes and continuing education on pain management.
