Problemas como el cambio climatico, el aumento de la poblacion mundial y la urbanizacion, la intensificacion de la produccion pecuaria y agricola, la disrupcion de los ecosistemas asi como la globalizacion del comercio y el transito humano, entre otros, hacen necesaria la revision de las estrategias tradicionales en Salud. Existen numerosos antecedentes historicos que documentan el afan de integrar diferentes dimensiones en el campo de la Salud, aunque fue a a partir de los primeros anos de este siglo que el enfoque “Una Salud” se formalizo e institucionalizo como una estrategia sistemica para la promocion de la Salud Publica. Entre los desafios a abordar desde la perspectiva de “Una Salud” se pueden mencionar la disponibilidad e inocuidad de agua y alimentos, la resistencia a antimicrobianos y la emergencia, reemergencia y propagacion de zoonosis. Desde un punto de vista operativo se debera considerar el desafio que representa para nuestras regiones, teoricas protagonistas de las politicas en el marco de “Una Salud”, la aplicacion de instrumentos de accion global gestionados fundamentalmente por los gobiernos y las corporaciones de los paises centrales. Palabras clave: una salud, salud publica, salud humana, salud animal. EnglishHuman and animal health face a complex scenario associated with global change that challenges the paradigms to which both fields have traditionally been confronted. Problems such as climate change, the increase in world population and urbanization, the intensification of livestock and agricultural production, the disruption of ecosystems and globalization of trade and human transit, among others, make necessary to review the strategies to promote public health. There are numerous historical precedents that document attempts to integrate different dimensions in the field of health, although it was just in the first years of this century that the \"One Health\" approach was formalized as a strategy for the promotion of public health. Availability and safety of water and food, resistance to antimicrobials and the emergence or re-emergence of zoonoses can be mentioned among the challenges to be addressed by the \"One Health\" framework. We must consider the challenge that represents for our regions, theoretical main receptors of the policies in the framework of \"One Health\", the application of global action instruments managed by governments and corporations in the developed countries. Key words: one health, public health, human health, animal health.","PeriodicalId":32689,"journal":{"name":"Veterinaria Montevideo","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76813068","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

La oveja y su(s) cordero(s) establecen un vinculo fuerte y selectivo inmediatamente despues del parto, el que es mediado por senales olfativas, auditivas y visuales. Luego del parto, si la oveja acepta su cria como propia, le permite la ingesta de calostro, pero en el caso contrario rechaza a la cria con comportamientos agresivos. Durante el periodo de lactacion los cuidados maternos evolucionan hasta la independencia alimenticia total de la cria, finalizando con el destete natural. Sin embargo, en la mayoria de los sistemas de produccion ovina se realiza un destete artificial que provoca cambios comportamentales y fisiologicos indicativos de estres. En el caso de Uruguay el sistema de cria ovina predominante es extensivo, basado en el pastoreo de campo natural, el que presenta una marcada disminucion en la produccion de forraje durante el invierno, momento en el que las ovejas estan gestando. En estas condiciones las ovejas prenadas sufren una restriccion nutricional, pierden peso y condicion corporal, lo que afecta negativamente el peso y las reservas energeticas de sus crias al nacimiento, asi como el establecimiento del vinculo entre la oveja y su cordero. Las fallas en el establecimiento del vinculo madre-cria, son las principales causas de los altos indices de mortalidad posnatal de corderos y de la baja eficiencia reproductiva de estos sistemas. La disminucion en la produccion de leche de las ovejas compromete el desarrollo de los corderos, lo que tambien repercute en la evolucion del vinculo madre-cria y la respuesta de estres al destete. Palabras clave: comportamiento materno, subnutricion, gestacion, produccion de leche, crecimiento del cordero, destete EnglishThe aim of this review was to summarize and to discuss the available information about the effects of subnutrition during gestation on ewe-lamb bond at lambing and during lactation period. The bond between the ewe and the lamb, that is highly selective, is established immediately after lambing through olfactory, auditory and visual signals. Immediately after lambing, if the ewe accepts the lamb, it allows it to suckle colostrum; however, if it does not accept it, she rejects it with aggressive behaviours. During the lactation period, the maternal care changes until the total independence of the lamb, ending in natural weaning. However, in most productive systems, lambs are separated from the dams at an earlier age, provoking behavioural and physiological responses indicative of stress in both, the ewe and the lamb. In Uruguay, sheep breeding systems that predominate are extensive, based on grazing native pastures, presenting a great decrease in forage availability in winter, when ewes are pregnant. Thus, pregnant ewes suffer a nutritional restriction, losing body weight, ","PeriodicalId":32689,"journal":{"name":"Veterinaria Montevideo","volume":"23 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87344159","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

EnglishOn March 2017, a clinical episode of heat stress in Holstein cows was diagnosed in a dairy farm from southwest Uruguay. After the consumption of the morning feed, 6 of 189 cows presented dyspnea, orthopnea, and open-mouth breathing. One cow died during the manifestation of these clinical signs, the other five cows recovered a few minutes afterwards. Another cow died the night before. There were no lesions in the respiratory system. The maximum Temperature Humidity Index (THI) recorded on February 27-28 and March 1 was 83.5, 83.5 and 83.0, respectively, indicating a heat wave and moderate heat stress. No ergoalkaloids were detected upon toxicological evaluation of the feed. The sudden onset of clinical signs, the lack of lesions in the respiratory tracts, and the moderately elevated THI registered for a prolonged period, indicated an acute clinical episode of heat stress with fatal outcome. The retrospective analysis of the daily THI and average milk production revealed that the clinical episode was preceded by a marked subclinical reduction of milk production from February 15 to March 2, associated with a high THI registered in that period. This was followed by a partial recovery of milk production between March 3 and March 15, in association with a concomitant reduction of the THI and, therefore, of heat stress. This report highlights the need for applying adequate mitigation strategies to prevent and control heat stress during summer in dairy cows in Uruguay.
