The development of populations of gastrointestinal parasites resistant to antihelmintics has led to seeks new alternatives its control. Stimulation of natural immunity by means of animal nutrition has shown promising results in controlling nematodes in sheep. The addition of protected fat sources, containing essential fatty acids, may be an alternative due to many effects, among them, regulation of immunity expression and regulation of the inflammatory response by immune effectors. The aim of this study was to estimate correlations between haematological and parasitological patterns, animal performance through weight and body condition, under the influence of protected fat in ewes. Fifty Santa Ines sheep, in the final third of pregnancy or postpartum, in paddocks of Panicum maximum, received, individually, 200 g per day of concentrate, isonitrogenous and isocaloric diets, with or without the addition of protected fat. In general, except for total leukocytes and eosinophils, almost all of Pearson correlation coefficients of other variables were significant. However, the protected fat, in the amount offered, had no antihelmintic effect.

From the study of the news, it is possible to notice a substantial and progressive increase in the number of reports that use social networks as a source for the composition of the news in recent years. This paper discusses precisely this process of legitimation of social networks as an authorized source for journalists from the perspective of the standards narration codes historically marked that journalists use to tell their stories, in a crossover between the ideas of Michel de Certeau, Paul Ricoeur and Roland Barthes. We will study the notion that this increase is due to a repositioning of journalistic values in vogue (who put those sources within the boundaries of acceptable) and has visible consequences in the writing and structuring of journalistic report as an enunciative technical.

This work deals with the historical survey of the class for the Devonian layers, general characteristics of the group and taphonomic preservation standards associated with the group. It was analyzed specimens of scientific collections from brazilian museums and universities. The taxonomic group is represented by four genera in the basins of Parana, Parnaiba and Amazon: Tentaculites, Homoctenus, Styliolina and Volynites. The tentaculitids occur from Ordovician to the Devonian, having its peak in the Middle Devonian. The class has three known orders: Tentaculitida, animals of benthic habit, Homoctenida and Dacryoconarida, animals of habit planktonic. It was also noticed the presence of two patterns of taphonomic conservation: isolated and grouped specimens.
