Cet article s’intéresse au tourisme scientifique. Il propose par une revue de littérature de définir et de distinguer les différents types, formes, caractéristiques et pratiques du tourisme scientifique. Notre contribution a pour finalité de mettre en exergue l’apport du tourisme scientifique au développement de l’enseignement supérieur aux universités Marocaines ; cas de l’Université Mohammed V Souissi Rabat. Ce papier développe les connaissances acquises ainsi que les expériences tirées lors des journées scientifiques, des tables rondes, des séminaires, des colloques et des congrès. Aussi, La construction de connaissance en tourisme passe par la publication aux revues scientifiques, journaux, livres pédagogiques et les cahiers collaboratifs qui jouent un rôle crucial dans la reconnaissance du tourisme. Enfin, cette étude vise à créer une synergie entre les différentes cultures universitaires et encourager les professeurs et les jeunes chercheurs à profiter de chaque opportunité et à dépasser les obstacles auxquels ils peuvent confrontés. La méthodologie utilisée est basée sur une étude qualitative par le biais des entretiens semi directifs menée auprès des professeurs chercheurs et des doctorants de l’Université Mohammed V Rabat ayant déjà eu l’opportunité de présenter des travaux de recherches scientifiques ou d’assister à des colloques d’ouvertures à l’international.
Pregnancy, parturition, and lactation represent physiological changes of organism, which activates adaptation mechanisms dedicated to maintain homeostasis during peripartum period. Despite of the appropriate input of calcium and phosphorus, the homeostasis of phosphocalcic metabolism is sometimes faulty, in particular among animals with high production potential. The aim of this study is to define usual values of calcium and phosphorus during pregnancy and postpartum period. This paraclinic tool will serve to a good interpretation when used by veterinarians. A second goal is to study the influence of physiological stage on phosphocalcic metabolism in milch cow. The hereby study was conducted on 17 Prim' Holsteins cow breed from 3 to 5 years old, clinically healthy, multiparous and derived from two dairy farms located in the wilaya of Constantine. Blood samples were taken from the jugular vein using dry tubes at different physiological stages (early gestation, mid gestation, late gestation, pre-partum, one day after parturition, and one month postpartum). All of the samples correctly identified were transported to a specialized laboratory where specific kits were used. Blood calcium and phosphorus levels have significantly varied depending on physiological stage (p < 0.01). They showed a high pre-partum variation, with a rate of 94.71 mg/mL and 61.99 mg/mL, respectively. These results can be used as means of follow-up reproduction for a better management of dairy farming.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
