Democracy in Brazil is recent and poses challenges to citizens in terms of political positioning, especially in the 2018 presidential elections, which were characterized by polarization, the spread of fake news and the use of social media to promote the candidates' agenda. In this context, we aim at analysing the discursive resources of pre-candidates to the 2018 Brazilian presidential elections. The Critical Discourse Analysis (FAIRCLOUGH, 2003) and Systemic Functional Linguistics (HALLIDAY, 2014) approaches were used to analyse the transcription of excerpts of six interviews from the Roda Viva TV show. The results point out that the discourse of: a) Álvaro Dias shows a pre-candidate willing to invest in education financially; b) Ciro Gomes constructs the image of experience and authority in the field of education; c) Henrique Meirelles emphasizes the relation between education and workforce development; d) Manuela D'Ávila supports the states and municipalities autonomy in their capacity to manage education locally and is aligned with women's experience as mothers, workers and citizens; e) Geraldo Alckmin will direct efforts to kindergarten education, aiming at reducing inequality; f) Jair Bolsonaro advocates eliminating the low-income and minorities quotas in public universities by investing in Basic Education in order to provide equal access to all students when they finish high school. ; A democracia no Brasil é recente e coloca desafios aos cidadãos em termos de posicionamento político, especialmente nas eleições presidenciais de 2018, que foram caracterizadas por polarização, disseminação de boatos e uso de redes sociais para promover as propostas dos candidatos. Nesse contexto, objetivamos analisar os recursos discursivos de pré-candidatos às eleições presidenciais do Brasil em 2018. A Análise Crítica do Discurso (FAIRCLOUGH, 2003) e a Linguística Sistêmico-Funcional (HALLIDAY, 2014) são utilizadas para análise da transcrição de excertos de seis entrevistas do Programa Roda Viva. Os resultados apontam que o discurso de: a) Álvaro Dias mostra um pré-candidato disposto a investir financeiramente na educação; b) Ciro Gomes constrói a imagem da experiência e autoridade no campo educacional; c) Henrique Meirelles enfatiza a relação entre educação e desenvolvimento de força de trabalho; d) Manuela D'Ávila apoia a autonomia dos estados e municípios para administrar localmente a educação e está alinhado à experiência das mulheres como mães, trabalhadoras e cidadãs; e) Geraldo Alckmin irá direcionar esforços para a educação infantil para diminuir a desigualdade; f) Jair Bolsonaro é favorável à eliminação das cotas no ensino superior por meio de investimentos na Educação Básica para proporcionar condições de acesso igualitárias a todos.PALAVRAS-CHAVE: Educação; Discurso político; Eleições presidenciais de 2018.

This study examines rumen-fluid parameters and the biochemical profile of feedlot sheep supplemented with a commercial product composed of yeast culture and enzymatically hydrolyzed yeast during an abrupt change of diet. Eight sheep at 30 months of age, with an average weight of 40.2 ± 3.4 kg, were housed in individual stalls where they received the same diet twice daily, which was formulated according to the National Research Council [NRC] (2007). The animals were divided into two groups, namely, supplemented with Saccharomyces cerevisiae (SG, n = 4) and control (CG, n = 4). The experiment consisted of three periods: the first (seven days) consisted of an acclimation to the roughage-only diet; in the second period (five days), the animals of SG started to receive supplementation; lastly, in the third period (five days), all animals underwent a sudden change of diet, which was characterized by an alteration from 100% roughage to a 50:50 ratio (roughage:concentrate) without prior adaptation. Blood samples were collected to evaluate albumin, aspartate amino transferase, calcium, gamma glutamyl transferase, globulins, glucose, magnesium, potassium, sodium, total plasma proteins and urea. Rumen fluid was harvested to evaluate physical aspects. Supplementation increased the protozoa count; the rate of sedimentation and fluctuation remained within the physiological parameters; and total plasma proteins and globulin decreased. Therefore, the yeast appears to be a promising alternative for reducing the deleterious effects of an abrupt change of diet.
