Composição Corporal e Exigências Nutricionais de Magnésio, Potássio e Sódio de Cordeiros Santa Inês em Crescimento dos 15 kg aos 25 kg de Peso Vivo

This study was carried out to determine body composition and magnesium, potassium and sodium requirements for weight gain of Santa Ines lambs (hairy coat breed). Eighteen animals were used with average 15 kg initial LW. At the beginning of the experiment, six animals were slaughtered for the determination of the amount of each mineral retained in the body, and serving as reference animals in the comparative slaughter technique. The remaining 12 animals were divided in two groups: six were ad libitum fed and six animals were restricting fed at maintenance plus 20%. The animals from the ad libitum and restrict feeding groups started in the experimental period by pairs and they both were slaughtered when the animals from the ad libitum group reached 25 kg LW. The estimates of magnesium, potassium and sodium body composition were obtained through the prediction equations obtained by the logarithm regression of the amount of each present minerals in the empty body in function of the empty body weight (EBW). The net requirements for weight gain were obtained through the derivation of these prediction equations. The estimates of body composition per kg EBW for the animals from 15 to 25 kg were: 0.591 and 0,578 g for Mg: 2.914 and 2.776 g for K 1.830 and 1.637 g for Na; and the net requirements for kg weight gain were: 0.515 and 0.503 g for Mg: 2.408 and 2.294 g for K; 1.315 and 1.177 g for Na, respectively

Percepções de gestantes sobre atenção odontológica durante a gravidez The beliefs of pregnant women about dental care during gestation

O presente artigo tem como proposta discutir a percepção de gestantes usuárias do Sistema Único de Saúde e também as assistidas em serviço privado conveniado sobre saúde bucal no período gestacional, por meio de entrevistas semi-estruturadas, cujos dados foram objeto de análise de conteúdo. Foram realizadas entrevistas até obter-se saturação em relação à compreensão dos objetivos dessa pesquisa, totalizando vinte. A análise e interpretação dos dados mostraram a existência de mitos, medos e restrições relacionados à atenção odontológica no pré-natal. A busca pela atenção odontológica entre as usuárias do SUS é mais rotineira e sistemática durante o pré-natal devido à oferta programática realizada neste período pelas Unidades Básicas de Saúde (UBS), sendo uma oportunidade de resolver problemas odontológicos pré-existentes. Identificou-se entre as gestantes assistidas por convênio a existência de atenção odontológica programada em outras épocas e evitadas durante o pré-natal.<br>The objective of this study was identifying beliefs of pregnant women, both users of the Unified Health System (the Brazilian Healthcare System) and women assisted by the private sector, with respect to oral health and dental care during their pregnancy. The approach used in this survey was theme-based qualitative content analysis. The subjects' comprehension of the objectives of this study was checked in semi-structured interviews, a total of 20. Analysis and interpretation of the collected data revealed the existence of myths, fears and restrictions with regard to prenatal dental care. According to our findings the users of the Unified Health System seem to have dental visits on a more systematic and regular basis than the users of the private health sector, probably because the dental services offered by the prenatal program of the Primary Care Units is providing them with an opportunity to solve pre-existing dental problems. On the other hand, the users of the private health system seem to avoid scheduling dental visits during pregnancy
