Fontes de proteína e carboidratos para cães e gatos

O mercado de alimentos para cães e gatos absorve importante quantidade de proteínas e carboidratos, apesar disso poucos estudos existem sobre digestibilidade e energia metabolizável destes ingredientes. Arroz e milho têm sido considerados as melhores fontes de amido, mas demonstra-se que o sorgo é igualmente bem digerido por cães. Na interpretação dos estudos, deve-se distinguir os que empregaram farinhas ou amidos purificados dos que empregaram ingredientes moídos, como utilizado na fabricação de alimentos para animais de companhia. Além de sua digestibilidade e valor energético, amidos interferem na glicemia de cães, o que torna interessante se empregar, para animais em condições específicas, fontes de carboidrato que levem à menores respostas de glicose e insulina. Devido a elevada necessidade de proteína, ingredientes protéicos são importantes nas formulações. Proteínas de origem animal apresentam maior variação em composição química, qualidade e digestibilidade que as de origem vegetal. Farinhas de origem animal podem apresentar excesso de matéria mineral, limitando sua inclusão na fórmula, enquanto derivados protéicos vegetais apresentam diversos fatores anti-nutricionais que devem ser inativados durante seu processamento. Demonstra-se que proteínas vegetais apresentam boa digestibilidade e energia metabolizável para cães e gatos, sendo sua inclusão interessante para reduzir a matéria mineral da dieta, controlar o excesso de bases do alimento e manter adequada a digestibilidade do produto, neste sentido soja micronizada e o farelo de glúten de milho 60% se destacam em digestibilidade e teor de energia metabolizável. A farinha de vísceras de frango, dentre as proteínas de origem animal secas demonstra-se como a de melhor digestibilidade e energia metabolizável.

O sindicato como espaço de construção da profissão docente

This work examines the connection Syndicate/teachers profession trying to unveil the important role taken over by the Syndical movement in the process of professionalization of the militant teachers. For that, it describes and analyses the historical course of three Syndicates representatives of the teachers category Associação dos Professores Licenciados da Bahia APLB; Sindicato dos Trabalhadores em Educação de Pernambuco SINTEPE; Sindicato dos Servidores Municipais de Petrolina SINDSEMP acting in the micro-region of the San Francisco Valley, especially, in the municipalities of Juazeiro Bahia , and of Petrolina Pernambuco. It concentrates its interests on the contribution of the Syndicates for the professional development of these teachers in this region analysing the aspects related to emerging conflicts into the Syndical organization, to the attitude of these entities before the educational reality to their reinvindicative struggles to the formative dimension of the group actions. This study tries to answer the following questions: How has this syndical movement of teachers of state school of S. Francisco Valley been characterized? How do their actions reflect in the formation and professionalization of the teachers? Do teachers recognize the syndicate as a constructive space for the teaching profession? The methodological trajectory was directed through a qualitative approach of an etnomethodological character, using instruments for the understanding of this reality, The treatment of the data was based on the interpretative analysis of the speeches present in documents and through answers of the interviwees, having as a reference in this analysis the theoretical studies about syndicalism and the teacher professionalization. For a conceptual construction of this work it was studied these two categories from their genesis, from the social historical evolution of their concepts and the up to date discussions that give explanations about the teachers syndical movement and about the process of teachers professionalization. As thesis of this study it was defended the idea of that the teachers syndicates have contributed expressively in the process of the construction of the teacher profession of the militant teachers of this in the micro-region of the S. Francisco Valley. Once the teachers participate actively in this movement promoted by the syndical entities, the teachers develop the critical sense of the educational realty; improve their formation and reinvindicate from the State this condition as a Right; fight for better conditions in the work; reinvindicate the salary valuation and, try to construct an image of teacher basing on a professional model. The contribution of the Syndicate in the process of teachers profissionalization, is more evident in its external dimension that chacterizes the profissionalism, on the related aspects: to the forms of participation in the definition and the management of the educational politics; to the political struggles for the achievements of the professional status, to the recognition and of his eventual valuation. The syndical actions have repercussions with less intensity in the inside dimension that defines the profissionality, in the related aspects: to the administratation of the pedagogical processes in schools and in the classroom; to the acquisition of branches of knowledges; to the epistemological criticism of the acquirements mobilized in the teaching; the curricular question to the mediation that make possible the learning at school and in the classroom

A estética da Commedia dell Arte: contribuições para o ensino das Artes Cênicas

Theatrical phenomenon borned in the Italy the Comedy dell Art concerned to it climax in the XVI century and spreading itself by the word than can be sight like the theatre base modern. Lasting parallel the conventional theatre since the three hundred years, this gender influenced significativly the making theatrical in the Europe graces the popular character of its simulation turned for the improvise. In spite of treat a theatric manifestation no more existing in the present time, we understand that the Comedy dell Art was constituted in one artistic language whose esthetics centralized in the popular fanciful and in the improvise permitted a rich possibility of verbal and not-verbal communication that today can to be taken again in contemporary productions theatricals. Departing of an approach of esthetics, this work has with purpose concentrate the references esthetics that configure that one artistic manifestation such that one references can contribute for the Arts teaches in the present times. We appeal the text and image of Comedy dell Art, such this historical reference that in context, with fountain investigated that mean and if complementary in one esthetic reflection for the creation of meaning diverse and news interpretations for the purpose investigated if having with base some analysis categories such as: the actor s body, the actuations spaces and the esthetics categories such the ugly, the comic and the absurd. To investigate the Comedy dell Art esthetic in the ambit of the teach of Arts Scenics is a manner of be understand the artistic universe of three century behind that can be meant, revived, in the marking possibilities of an art teach able to incentive the critical, the appreciation, the discussion and the transgression of instituted true. Having investigated the exhibition Comedy dell Art esthetic we rebound four stich that we judge significative for we think the Arts Scenics teach, they are: the articulation between actor s body, the text and the space actuation in the play; statement what it is given between actor s body and the on-looker and the every gesture that did share of scene in a popular scenic space; a conception actor s body that transgress with the true duty socially that is capable the to admit its dimension Dionysian, creative and ambiguous in the to do theatrical; the text conception that get beyond the ambit the word writing by the dramatist and talked by actors, if spreading the other elements significance in the scene like gesture, the parody, the recent news, the gags and the word used in the day-to-day; the scenic space like a statement symbolic between actors and on-looker that make a quality of amusement pact supported by the scenic true of artist that actuate in not usual spaces bid at an auctioning degrees of participation in the building the scenic phenomenon; and the importance of esthetics categories such as the ugly, the comic and the absurd, those categories that foundation like a do scenic transgressor make a possible exchange mutual between actor and appreciator. The statement of esthetics categories in joint continuous between the body, the text and the scenic space evident themselves in doing theatrical and in the its appreciation. We believe that the reflection esthetic about the Comedy dell Art in the arts class, consider the stich detached, can favor possibilities of to share discovery, ideas, feelings and attitudes, and can permit the observation of different stich of view, establishing the statement of individual with the group in a participative and democratic form

Fontes de fibra na alimentação do pacu: desempenho, composição corporal e morfometria intestinal

O objetivo deste estudo foi avaliar os efeitos da utilização de diferentes ingredientes fibrosos nas dietas sobre o desempenho, a composição corporal e a morfometria intestinal de juvenis de pacu. Foram avaliadas cinco dietas isoproteicas (23% de proteína digestível), isoenergéticas (3250kcal de energia digestível/kg) e isofibrosas (9% de fibra bruta), sendo a principal fonte fibrosa de cada constituída por farelo de soja, casca de soja, farelo de girassol e polpa cítrica; esta última em dois níveis de inclusão (30 e 45%). Foram utilizados 300 juvenis de pacu (25,12±0,78 gramas), alojados em 25 aquários (200 litros). Os melhores resultados de crescimento e conversão alimentar foram obtidos com as dietas contendo farelo de soja e farelo de girassol. As dietas contendo casca de soja e polpa cítrica prejudicaram o desempenho dos juvenis de pacu, e o efeito negativo foi acentuado com o aumento da inclusão de polpa cítrica. Além disto, somente nos peixes alimentados com a dieta com 45% de polpa cítrica foi observada diminuição na densidade de vilosidades por área no epitélio intestinal. A partir dos resultados obtidos, pode-se concluir que alguns ingredientes fibrosos podem afetar negativamente o desempenho e as características do epitélio intestinal de juvenis de pacu.

Digestibilidade e ganhos em peso de ovinos alimentados com diferentes fontes de volumosos e recebendo somatotropina recombinante bovina (rBST)

O objetivo deste trabalho foi avaliar os efeitos da aplicação de 20 mg de somatotropina recombinante bovina (rBST) de liberação lenta, em períodos de 14 e 28 dias, sobre a ingestão de matéria seca, os coeficientes de digestibilidade de matéria seca (MS), fibra em detergente ácido (FDA), proteína bruta (PB) e energia bruta (EB), o balanço de nitrogênio e o ganho de peso diário, em rações à base de silagem de milho, cana-de-açúcar ou bagaço hidrolisado e concentrado. Foi usado um total de 24 borregos mestiços, não-castrados, com média de 4 a 5 meses de idade e 22 ± 2 kg de PV. Não houve efeito da rBST na ingestão de matéria seca, nas digestibilidades de PB e FDA, no balanço de nitrogênio e no ganho de peso diário dos borregos. A digestibilidade da energia bruta foi influenciada pela aplicação de rBST, quando os diferentes volumosos ou períodos pós-aplicação hormonal foram considerados, porém, somente foi observado efeito da ação hormonal sobre a digestibilidade de MS nas dietas à base de silagem de milho.

Educação do campo e alternância :reflexões sobre uma experiência na Transamazônica/Pará

The study theme is the Rural Familiar House Program (RFHP), through the Rural Familiar House of Uruará-PA city (URFH), from 2000 to 2005. It is considered as base the education offered to the field young people, in the modality of basic education by alternation methodology between the Familiar and School Times in the two first from 5th to 8th grade classrooms. From the argument about the understanding importance and need of knowledge transmission and construction to be established in the inter-section between general references of the social reality and the subjective ones. It constitutes an educative work that both values domain of knowing and the creative capacity of each pupil. Considering that the greatest aim of the education is the human being emancipation, this thematic for the development of the documentary and field research was defined with the delimitated thematic for the educative practice-proposal in alternation, choosing the Program of the RFHs as the reference to carry out an analysis which considered fruitful in the articulation between education and educative work. This study had the objective to contribute for the debate concerning the alternation and to understand presuposals and educative practice of the RFHs what its importance for the young people and its relation with the field educational policy. For this, it was used, mainly, from analytical references of authors, such as Williams, Gramsci, Adorno, Freire, Shiva, Soares, Molina, Tonet, et. all, all were also important for the construction of this work. The studied documentary sources, as well as the verbal ones the actors also interviewed had allowed, in irreplaceable way and significantly, a critical analysis on the pedagogical proposals and the articulation among school, familiar work and education, which was carried out in the formation of URFH, the sessions of alternation between Time School and Time Family. The results are scored with the chapter construction, as they had presented themselves in several sources and the reading which was made. A reading that signals for the affirmation which is possible to overtake the emphasis on technicality, mediated in the practice-theory-practice relation, still present in the alternation, and, thus, to be able to make an educative work that intends to contribute for the young people education with capacity of being, thinking and to act actually as subjects of their history

Em busca de novas territorialidades pedagógicas para a identidade da Educação Física no Ensino Médio integrado: uma perspectiva pós-crítica

Cet étude s agit du domaine de l Éducation Physique comme composante curriculaire dans le contexte de l Ensino médio integrado (l enseignement secondaire professionnel intégré) dans le IFRN, Campus Natal Zona Norte (Régio Nord). Son objectif principal est sur le plan éducatif des actions de l enseingant au procès des convivialités avec la culture corporale à partir des expériences, désires, besoins et volontés des apprenants dans la perspective de l imersion dans le monde de la créativité, de la recherche, de la connaissance et de la transformation de l identité pédagogique de la composante curriculaire. Dans ce sens, l étude a eu comme objectif l élaboration d une propisition pédagogique, fondamentée sur la Théorie Post-critique de l éducation qui contribue pour la configuration de l identité de l Éducation Physique dans les cours téchniques intégrés de niveau secondaire. La recherche s est configuré dans une intervention pédagogique fondamenté sur les préssuppositions methodologique d une expérience empirique du genre recherche-action apliqué dans l univers scolaire des cours thécniques intégrés de l enseignement secondaire de l IFRN, Campus Natal Zona Norte. Les sujets qui ont participé de la recherche, sont les apprenants des groupes de la première année du cours de Commerce et Éléctronique de la soirée (13h à 18h), inscrit à partir de l année 2012. Les instruments utilisés pour la recherche ont été deux questionaires et une cahier de bord. Les résultats obtenus sont disposés dans des graphiques qui représentent les paroles des sujets après le procès d intervantion et les analyses réalisées sous l étude-recherche, qui ont été faites por l analyse de contenu, de l image principale de la population recherchée. On considère que les résultats de la recherche ont été plausibles à la mesure que au-delà du support et de la participation dans la recherche, les réponses obtenues ont démontré que le procès d intervantion pédagogique a été pertinent pour les apprenants des cours téchniques intégrés de niveau secondaire de Commerce et Électronique de l IFRN, Campus Natal Zona Norte. Le sense essentielle de cette thèse s est concentrée dans la dimension interculturelle pour l Éducation Physique dans le secondaire intégré, comme un travail fondamenté à partir des temoignage des apprenants et par la conception post-critique du curriculum qui refuse les explications évidentes et instituées comme des véritées finales dans l objectif de réguler et controler les sujets de l éducation. L option faite par cet abordage de thèse a été pour rompre avec l établi à partir de la proposition d un dialògue, avec les apprenants, à la recherche de nouveaux territoires pédagogiques pour l Education Physique à l enseignement intégré de l IFRN, Campus Natal Zona Norte. Des territoires qui occupent des espaces dans la culture scolaire, dans une dynamique dialogique avec les apprenants, qui se défine politique et pédagogiquement pour la diversité culturelle du mouvement, qui aborde le concept de mouvement dans la proximité des actions corporales cotidiennes et qui propose de nouvelles possibilités et de recréations pour les pratiques de la culture corporale. La perspective post-critique ouvre des possibilités pour de nouvelles langages en fortifiant les narratives de ce qui ont toujours entendu et cependant ont silencié ses voix et ainsi, la thèse a confirmé que, l étude présent et la recherche supporté par la théorie post-critique du curriculum ont possibilité une nouvelles configuration pour l identité pédagogique de l Éducation Physique dans la condition de composant curriculaire des cours téchniques intégrés de niveau secondaire de l IFRN au Campus Natal Zona Norte

Exportação de nutrientes pelos frutos de melancia em função de épocas de cultivo, fontes e doses de potássio

Foram conduzidos dois experimentos em propriedades rurais, localizadas próxima a cidade de Borborema (SP), de outubro a dezembro/2001 e de fevereiro a abril/2002, com o objetivo de determinar as quantidades exportadas de nutrientes pelos frutos de melancia, em função de fontes e doses de potássio, em duas épocas de cultivo. O delineamento experimental utilizado foi o de blocos casualizados completos, em esquema fatorial 3x4, com três repetições, sendo avaliados as fontes: cloreto, nitrato e sulfato de potássio e as doses: 50; 100; 200 e 300 kg ha-1 de K2O. Com exceção do Mg, as maiores exportações de nutrientes pelos frutos foram obtidas no cultivo de outubro a dezembro. A massa seca e as exportações de N, P, K, e Ca aumentaram de forma quadrática com as doses de potássio. A aplicação KCl aumentou respectivamente, de forma quadrática e linear, as exportações de S e Cl pelos frutos de melancia.

Fontes e doses de nitrogênio para o feijoeiro em sucessão a gramíneas no sistema plantio direto

O nitrogênio é um nutriente essencial ao feijoeiro. Contudo, ainda há dúvidas sobre qual fonte e dose utilizar para o fornecimento desse nutriente em cobertura à cultura, no sistema plantio direto. O objetivo deste trabalho foi avaliar a influência de fontes e doses de N, aplicadas em cobertura, na nutrição e produtividade do feijoeiro (Phaseolus vulgaris L.) cultivado no sistema plantio direto, em um Nitossolo Vermelho. O delineamento experimental foi o de blocos ao acaso com quatro repetições, num esquema fatorial 2x4, constituído por duas fontes de N (nitrocálcio e uréia) e quatro doses de N (0, 30, 60 e 120 kg ha-1) em cobertura. A aplicação de doses elevadas de N, na forma de nitrocálcio, promoveu maior absorção de nitrato, K, Ca e Mg pelo feijoeiro em plantio direto, em comparação com a aplicação de uréia. A adubação nitrogenada em cobertura, utilizando como fonte o nitrocálcio ou a uréia, proporcionou aumento no teor de N nas folhas, na massa de matéria seca da parte aérea, no número de vagens por planta e na produtividade do feijoeiro no sistema plantio direto, em sucessão a aveia-preta, até a dose estimada de 95 kg ha-1 de uréia.

Manejo da adubação nitrogenada paraa batata-doce: fontes e parcelamento de aplicação

Com o objetivo de avaliar o rendimento da batata-doce [Ipomoea batatas (L.) Lam.], cultivar Rainha Branca, submetida a fontes e parcelamentos da aplicação de 80 kg ha-1 de nitrogênio, instalou-se um experimento, no período de abril a agosto de 2007, na Universidade Federal da Paraíba, em Areia. O delineamento experimental utilizado foi o de blocos casualizados, em esquema fatorial 2 x 7, com duas fontes de nitrogênio (uréia e sulfato de amônio) e oito de épocas parcelamentos da aplicação (100% no plantio; 100% aos 30 dias após o plantio (DAP); 100% aos 60 DAP; 50% no plantio e 50% aos 30 DAP; 50% no plantio e 50% aos 60 DAP; 50% aos 30 e 50% aos 60 DAP; 33% no plantio, 33% aos 30 e 33% aos 60 DAP), com quatro repetições. Foram avaliados o peso médio de raízes comerciais, a produção e o número de raízes comerciais por planta e as produtividades total e comercial de raízes de batatadoce. O maior peso médio de raízes comerciais (294 g) foi obtido com o parcelamento do N, como uréia, 50% no plantio e 50% aos 30 DAP. O parcelamento de N 33% no plantio, 33% aos 30 DAP e 33% aos 60 DAP na forma sulfato de amônio foi responsável pela maior produção de raízes comerciais por planta (337 g). Para o número de raízes comercias e as produtividades total e comercial, o N na forma de sulfato de amônio parcelado 33% no plantio, 33% aos 30 DAP e 33% aos 60 DAP proporcionou os maiores valores, 1,50 raízes, 30,5 e 28,4 t ha-1, respectivamente.
