The variables studied were daily dietary intake (CRD), daily weight gain (GPD), feed conversion (CA), bone parameters, intestinal morphometry, intestinal microbiota diversity and economic viability of the experimental diets. Seventy five male and female piglets were used, with a mean initial weight of 25,024 ? 3,21 kg. The experimental design was a randomized block design, containing five treatments, five blocks totaling 25 experimental units composed of three pigs (two males and one female), with the following treatments: T1 = Reference diet; T2 = Basal diet with reduction of 100 kcal / kg of metabolizable energy; T3 = T2 + xylanase (100g / ton); T4 = T3 + probiotic (B subtilis and Bacillus Licheniformis) and T5 = T3 + symbiotic (B subtilis and Bacillus Licheniformis and Mananoligosaccharide). It was observed that the animals that received the T4 diet presented lower CRD (P 0.05) between treatments for any of the performance variables. In the total period (0-30 days) it was observed that T2 resulted in worsening of feed conversion in relation to T4, and no significant differences were observed between these treatments and the others. The T5 diet resulted in a higher ratio of villus height: crypt depths in the jejunum compared to T2. In relation to the microbial diversity of the cecal content, the relative abundance (% of OTUs) for the Firmicutes, Actinobacteria and Proteobacteria phylae independent of the treatment were observed at phylum level. While at the family level the greatest abundance was for Lactobacillaceae, Steptococcaceae and Clostrideacea. Growth pigs rations with reduction of 100 kcal/kg of ME and supplemented with xylanase, probiotic and simbiotic resulted in similar performance compared with the results of pigs receiving reference ration. The xylanase plus probiotic improved the feed convertion compared to the energetic reduction diet without these additives. The xylanase and symbiotic combination prooted the biggest villus height:crypth depth ratio. The joint use of xylanase and probiotic results in best economic efficiency and best cost ratio O experimento foi realizado com o objetivo de investigar a suplementa??o da enzima xilanase individualmente, ou associada com probi?tico ou simbi?tico na dieta de su?nos com redu??o do valor de energia metaboliz?vel. As vari?veis estudadas foram: consumo de ra??o di?rio (CRD), ganho de peso di?rio (GPD), convers?o alimentar (CA), par?metros ?sseos, morfometria intestinal, diversidade da microbiota intestinal e viabilidade econ?mica das dietas experimentais. Foram utilizados 75 leit?es machos castrados e f?meas, com peso m?dio inicial de 25,024 ? 3, 21 kg. O delineamento experimental foi o de blocos ao acaso, contendo cinco tratamentos, cinco blocos totalizando 25 unidades experimentais compostas por tr?s su?nos (dois machos e uma f?mea), sendo os tratamentos: T1= Dieta refer?ncia; T2= Dieta basal com redu??o de 100 kcal/kg de energia metaboliz?vel; T3= T2 + xilanase (100g/ton.); T4= T3 + probi?tico (B subtilis e Bacillus Licheniformis) e T5= T3 + simbi?tico (B subtilis e Bacillus Licheniformis e mananoligossacar?deo). Os animais que receberam a dieta T4 apresentaram menor CRD (P0,05) para as vari?veis de desempenho. J? no per?odo total (1-30 dias) foi observado que o T2 resultou em piora (P

Its was chosen a case study, in the scope of qualitative research, as the most appropriate approach to the investigative process, by reference, it was used questionnaires and interviews, as well as document analysis, fundamental to the process. The documentation issue was organized mainly from research on the Internet at specialized sites in the discussion of rural development. The bibliographical research has prioritized the reading of books and/or academic papers and doctoral theses and Master?s dissertations related to the topic. The study of monitoring reports, technical control of the family units and reports were used in the process as important analysis resources. The students? training was analyzed based on three main elements: the level of education, the training, the time formed as Agricultural Technician and the professional qualification, in terms of continuous education. The EAFC students with service activity in pig farming in the rural settlements in Northeast of Par? hold information on the swine activity disconnected from the reality of family farming, so it is necessary to reframe the curriculum, to rethink the teaching spaces of research and production sectors, as well as the teaching and learning process. Esta pesquisa foi realizada com os egressos do curso t?cnico em agropecu?ria da Escola Agrot?cnica Federal de Castanhal, Par? ? EAFC ?, que atuam em assentamentos da reforma agr?ria no Nordeste Paraense, tendo como objetivos: diagnosticar a a??o dos egressos da EAFC sobre a suinocultura praticada nestes assentamentos; analisar a concep??o norteadora do processo formativo dos cursos t?cnicos com ?nfase na suinocultura; identificar se a atua??o dos egressos da EAFC favorece a difus?o de conhecimentos na atividade suin?cola nos assentamentos da reforma agr?ria. Elegeu-se o estudo de caso, no escopo da pesquisa qualitativa, como o enfoque mais adequado ao processo investigativo, recorrendo-se, como procedimentos, aplica??o de question?rio e entrevista, bem como a an?lise documental, fundamental para o processo. A documenta??o tem?tica foi organizada, sobretudo, a partir de pesquisa na internet, em s?tios especializados na discuss?o do desenvolvimento rural. A pesquisa bibliogr?fica priorizou a consulta de livros e/ou trabalhos acad?micos como Teses de Doutorado e Disserta??es de Mestrado relacionados ao tema. O estudo de fichas de acompanhamento e controle t?cnico das unidades familiares, relat?rios, se constitu?ram, nesse processo, tamb?m em importantes recursos de an?lise. A forma??o dos egressos foi analisada a partir de tr?s elementos principais: o n?vel de ensino, de forma??o, o tempo de formado como T?cnico Agropecu?rio e a qualifica??o profissional, em termos de forma??o continuada. Os egressos da EAFC com atividade de assist?ncia t?cnica em suinocultura nos Assentamentos Rurais do Nordeste Paraense det?m a informa??o sobre a atividade da suinocultura desconectada da realidade da agricultura familiar, havendo a necessidade de ressignifica??o do curr?culo, de repensar os espa?os pedag?gicos dos setores de pesquisa e produ??o, bem como tamb?m faz?-lo com o processo de ensino e aprendizagem.

On the other hand, environmental education can be a means of generating ideas and actions to improve the quality of teaching in schools. Thus, the objective of this study was to propose that environmental education is applied in the swine industry of the Farroupilha Federal Institute ? Campus S?o Vicente do Sul (IFF - Campus SVS), and valued, both in practical classes, as in the theoretical . Thus, it was necessary to conduct an environmental analysis of waste management of these facilities, evaluating the students' perception about the environmental impacts. The result was, more than 68% of students are unaware of the harm that poor disposal of pig waste can cause to the environment. In step characterized by meetings and field research, students found that the IFF ? Campus SVS facilities are pigs in adverse conditions, so students do not show, appropriately, the correct way of handling the waste. After the fieldwork, students who participated and those who did not participate in the survey were asked again to verify the degree of learning. The result of this step showed that students who participated in the survey had a higher rate of correct responses, which shows that implementation of the Environmental Education methods are effective when applied effectively. As a result of the lack of increased workload on the topic "Swine and the Environment" in the disciplines of Environmental Management and Swine, the bad influence of facilities on learning, students found it difficult to correctly answer some simple questions of the questionnaires. It was also found that most students said that the facilities needed reforms because, as they themselves said, the facilities were poor and lacked space for practical classes. Thus, the final results have intensified the need for improvements in environmental education and care for the proper management of waste at IFF ? Campus SVS is therefore a necessary pedagogical proposal seeking to increase the amount of content related to the preservation of environment and proper management to pig farming waste. Because agricultural education, teaching practice dedicated to the preservation of the environment should be highlighted. From all the results found in this study, warned that the direction of the IFF - Campus SVS that need to be built new facilities for swine, with adequate infrastructure. As a consequence, in April 2011, the direction of the IFF - Campus SVS calls for a new project facilities for swine. In July 2011 the project was completed. Thus, it is considered that this work has contributed significantly to changes in posture in the face of reality presented, and attracted the attention of managers of the Institute, helping to make possible the implementation of projects for new facilities. A suinocultura ? uma atividade muito importante no cen?rio econ?mico do pa?s, por?m os dejetos de su?nos, se n?o forem corretamente tratados, tornam-se um poderoso poluidor ambiental. Por outro lado, a educa??o ambiental pode ser um meio de gerar reflex?es e a??es para a melhoria da qualidade de ensino nas escolas. Diante disso, o objetivo deste trabalho foi o de propor que a Educa??o Ambiental seja aplicada no setor de suinocultura do Instituto Federal Farroupilha Campus S?o Vicente do Sul (IFF ? Campus SVS), sendo valorada, tanto no ?mbito das aulas pr?ticas, como nas te?ricas. Para tanto, foi necess?rio realizar uma an?lise ambiental do manejo dos dejetos nessas instala??es, avaliando-se a percep??o dos alunos a respeito dos impactos ambientais. O resultado foi: mais de 68% dos alunos n?o sabem dos malef?cios que a m? disposi??o dos dejetos su?nos pode causar ao meio ambiente. Na etapa caracterizada pelos encontros e pesquisas de campo, os alunos verificaram que no IFF ? Campus SVS as instala??es de su?nos est?o em condi??es adversas, sendo assim, os alunos n?o evidenciam, de maneira apropriada, o correto modo de manejo dos dejetos. Ap?s a pesquisa de campo, os alunos que participaram e os que n?o participaram da pesquisa foram novamente questionados para a verifica??o do grau de aprendizado. O resultado dessa etapa mostrou que os alunos, que participaram da pesquisa, tiveram maior ?ndice de acertos nas respostas, o que demonstra que a aplica??o das metodologias de Educa??o Ambiental surtem efeito, quando aplicadas efetivamente. Em conseq??ncia da falta de maior carga hor?ria sobre o tema ?Suinocultura e o Meio Ambiente? nas disciplinas de Gest?o Ambiental e Suinocultura, al?m da m? influ?ncia das instala??es sobre o aprendizado, os alunos encontraram dificuldades em responder corretamente algumas perguntas simples dos question?rios. Constatou-se tamb?m que a maioria dos alunos manifestou que as instala??es precisavam de reformas, pois, como eles mesmos afirmaram, as instala??es estavam prec?rias e faltava espa?o para as aulas pr?ticas. Assim sendo, os resultados finais intensificaram a necessidade de melhorias na Educa??o Ambiental e na preocupa??o com o manejo adequado dos dejetos no IFF - Campus SVS. Portanto ? necess?ria uma proposta pedag?gica buscando aumentar a quantidade de conte?dos relacionados ? preserva??o do meio ambiente e ao manejo adequado para os dejetos da suinocultura. Por ser ensino agr?cola, a pr?tica de ensino voltada para a preserva??o do meio ambiente deveria ser evidenciada. A partir de todos os resultados encontrados nessa pesquisa, advertiu-se ? dire??o do IFF ? Campus SVS da necessidade que fossem constru?das novas instala??es de suinocultura, com infraestrutura adequada. Como conseq??ncia disto, em Abril de 2011, a dire??o do IFF - Campus SVS solicitou a elabora??o de um novo projeto de instala??es para suinocultura. Em Julho de 2011 o projeto foi conclu?do. Assim, considera-se que este trabalho contribuiu expressivamente para as mudan?as de postura, diante da realidade apresentada, e despertou a aten??o dos gestores do Instituto, colaborando para a viabiliza??o da execu??o dos projetos de novas instala??es.

The study design was randomized blocks, where blocks were floors of the cage, with three blocks, with five treatments and six replicates of 10 birds each, totaling 30 plots and 300 birds. Treatments used: reference diet with avilamicin; reference diet; reference diet with 0,1% cell wall of Saccharomyces cerevisiae (CWSc); reference diet with 0,2% of CWSc; reference diet with 0,3% of CWSc. In the period from 09 to 21 days of age the highest level of CWSc negatively influenced weight gain. In the period from 34 to 39 days, the level of 0,1% of CWSc provided better weight gain compared to treatment with antimicrobials, while the birds of the other treatments had intermediate values for this characteristic. Lower viability was observed in the period of 22 to 33 days of age to broilers fed diets with reference diet, while the other periods of age showed no differences between treatments. There were no statistical differences to feed consumption and feed conversion in period of 09 to 21 days of age, to feed consumption, weight gain and feed conversion in period of 22 to 33 days of age and to feed consumption and feed conversion in period of 34 to 39 days of age. In the total period of 09 to 39 days of age, were not significant differences between treatments for the performance variables. For carcass characteristics the highest value for weight was in the treatment with 0,1% of CWSc, the treatment with 0,3% had lower value. Absolute weight of drumstick and thigh+drumstick showed higher weight for the diets with 0,1% and 0,2% of CWSc, the lowest weight for the level of 0,3% and intermediate weight for the other treatments. The other parameters were not affected. There was no influence of CWSc and the antimicrobial on digestibility and total count of coliforms in the ileum. Changes were observed in the identification of the ileal microbiota as treatment change. The inclusion of CWSc can be performed up to 0,2% in the diets for broiler chickens without compromising animal production, metabolizability of nutrients and counts of coliforms in the ileum. The conclusion is that the CWSc may have diluted share, compared to performance enhancers in antimicrobial free diets. Este experimento teve como objetivo verificar os efeitos da inclus?o de parede celular de levedura (Saccharomyces cerevisiae) (PCSc) na dieta para frangos de corte criados em gaiolas quanto ao desempenho nos per?odos de 09 a 21, 22 a 33, 34 a 39 e 09 a 39 dias de idade, caracter?sticas de carca?a, peso dos ?rg?os, metabolizabilidade das dietas, contagem total e identifica??o de coliformes totais do ?leo. O delineamento adotado foi o de blocos casualizados, onde os blocos eram os andares da bateria met?lica, totalizando tr?s blocos, sendo cinco tratamentos e seis repeti??es de 10 aves por unidade experimental, totalizando 30 parcelas e 300 aves. Os tratamentos foram: dieta refer?ncia com avilamicina (AV); dieta refer?ncia (DR); dieta refer?ncia com 0,1% de parede celular de Saccharomyces cerevisiae (PCSc0,1); dieta refer?ncia com 0,2% de PCSc (PCSc0,2); dieta refer?ncia com 0,3% de PCSc (PCSc0,3). No per?odo de 09 a 21 dias de idade o n?vel mais elevado de PCSc influenciou negativamente no ganho de peso. No per?odo de 34 a 39 dias, o n?vel de 0,1% de PCSc proporcionou melhor ganho de peso em rela??o ao tratamento com antimicrobiano, que resultou em frangos com menor ganho de peso, enquanto as aves dos demais tratamentos tiveram valores intermedi?rios para esta caracter?stica. Foi observada menor viabilidade no per?odo de 22 a 33 dias para os frangos alimentados com dieta refer?ncia, n?o tendo diferen?a nos outros per?odos de idade entre os tratamentos. N?o foram observadas diferen?as estat?sticas para consumo de ra??o e convers?o alimentar no per?odo de 09 a 21 dias de idade, para consumo de ra??o, ganho de peso e convers?o alimentar no per?odo de 22 a 33 dias de idade e para consumo de ra??o e convers?o alimentar de 34 a 39 dias de idade. No per?odo total, de 09 a 39 dias de idade, tamb?m n?o foram observadas diferen?as estat?sticas entre os tratamentos para as vari?veis de desempenho. Para caracter?sticas de carca?a o maior valor para peso vivo foi para os frangos do tratamento com 0,1% de PCSc enquanto aqueles do tratamento com 0,3% obtiveram o menor valor. Os pesos absolutos de sobrecoxa e coxa+sobrecoxa apresentaram maiores pesos para as dietas com 0,1 e 0,2% de PCSc, menor peso para o n?vel de 0,3% e pesos intermedi?rios para os outros tratamentos. Os outros par?metros n?o foram influenciados. N?o houve influ?ncia dos tratamentos para metabolizabilidade e contagem total de coliformes totais no ?leo das aves. Foram verificadas altera??es na identifica??o da microbiota ileal conforme mudan?a de tratamentos. Pode-se incluir at? 0,2% de PCSc em dietas para frangos de corte sem que haja comprometimento no desempenho, nas caracter?sticas de carca?a, na metabolizabilidade dos nutrientes da dieta e na contagem total de coliformes totais no ?leo. Conclui-se que a parede celular de Saccharomyces cerevisiae pode ter a??o comparada aos melhoradores de desempenho em dietas livres de antimicrobianos.

This study was carried out to evaluate the chemical composition, the gross energy and the apparent digestibility of the nutrients of the barley bagasse (BB). For the chemical composition, three samples of the BB originated from the same beer industry were evaluated. Each sample of BB was submitted to the proximal analyses to determinate the dry matter (DM), gross energy (GE), crude protein (CP), ether extract (EE), ash, crude fiber (CF), neutral detergent fiber (NDF), acid detergent fiber (ADF), macro and micro minerals and the total carbohydrates (TCH) and macro and micro minerals levels. The average of 21,59; 5215,29 kcal/kg, 24,89; 10,82; 8,01; 15,99; 66,32; 24,24 e 56,28%, respectively, for the DM, GE, CP, FE, MM, CF, NDF, ADF, TCH, that were determinate had their values similar to that met in the literature, characterizing the BB as an ingredient of great potential for swine feeding. For the digestibility assay, it was used five barrows with 35,0 kg of bodyweight, housed individually in metabolic cages. The treatments consisted of one ration based on corn and soybean meal, formulated to growing pigs, and one ration test where the BB replace 40% of the control ration. The barrows were raised on metabolism cages during 12 days, with seven days for the adaptation to the cages and five days of feces and urine collection. It was used the iron oxide as fecal marker. The barrows were fed based on metabolic weight (kg0,75). It was used the method of total collect and the feces were collected twice daily at the morning and at afternoon, identified, weighted and kept in freezer. The urine was collected daily and kept in refrigerator. At the end of the experimental period it was made the analyzes of chemical composition of the rations, the feces and urine to determinate the digestibility of these nutrients and the balance of N and P. The DE of the BB was to 2983 kcal/kg. The replacement of 40% control ration to BB caused change in the nitrogen metabolism. Occurred reduction in the urinary excretion in the barrows fed with ration containing 40% of BB improving the utilization of N. Although, occurred reduction of retention of and in the digestibility of the DM, and the nutrients, CP, EE, MM, NDF, ADF, N and P. It concluded that the BB worsted the digestibility of the nutrients. O presente trabalho foi realizado com o objetivo de avaliar a composi??o qu?mica, a energia digest?vel e a digestibilidade aparente dos nutrientes do baga?o de cevada. Para a an?lise da composi??o qu?mica foram avaliadas tr?s partidas do BCV de mesma origem. As amostras foram submetidas ? an?lise proximal para determina??o da mat?ria seca (MS), energia bruta (EB), prote?na bruta (PB), extrato et?reo (EE), mat?ria mineral (MM), fibra bruta (FB), fibra em detergente neutro (FDN), fibra em detergente ?cido (FDA), macro e microminerais. As m?dias de 21,59; 5215,29 kcal/kg, 24,89; 10,82; 8,01; 15,99; 66,32; 24,24 e 56,28%, respectivamente, para MS, EB, PB, EE, MM, FB, FDN, FDA e carboidrato total encontradas nas tr?s partidas tiveram valores semelhantes aqueles encontrados na literatura, caracterizando o BCV como um ingrediente de grande potencial para ser utilizado na alimenta??o de su?nos. Para o ensaio de digestibilidade foram utilizados cinco su?nos machos castrados com peso m?dio de 35,0 kg. Os tratamentos consistiram de uma ra??o controle, formulada para atender as exig?ncias dos su?nos na fase de crescimento e uma ra??o teste, onde o BCV substituiu, na base na mat?ria seca, 40% da ra??o controle. Os animais foram alojados em gaiolas de metabolismo por um per?odo de 12 dias, sendo sete dias para adapta??o ?s gaiolas e as dietas e cinco dias para coleta de fezes e urina. Foi utilizado ?xido f?rrico como marcador fecal. Os animais foram pesados no in?cio do experimento e antes de iniciar as coletas para se determinar o consumo de ra??o que seria ofertado nesta fase. Cada su?no recebeu uma quantidade di?ria de ra??o restrita por unidade de peso metab?lico (kg0,75). As fezes foram coletadas diariamente no per?odo da manh? e da tarde, identificadas, pesadas e congeladas em freezer. A urina foi coletada uma vez ao dia, identificada, pesada e armazenada em refrigerador. Ao fim do experimento foi feita an?lise proximal das dietas, BCV, fezes e urina para determina??o da digestibilidade dos nutrientes e do balan?o do nitrog?nio e do f?sforo. A energia digest?vel do BCV foi de 2983 kcal/kg. A substitui??o de 40% da ra??o controle por baga?o de cevada alterou o metabolismo de nitrog?nio. Houve uma redu??o na excre??o urin?ria dos animais que receberam o BCV, aumentando a efici?ncia na utiliza??o do N deste tratamento. Contudo houve redu??o na reten??o do N e na digestibilidade da MS, PB, EE, MM, FDN, FDA, N e P. Concluiu-se que a caracter?stica fibrosa do BCV pode ter interferido de forma negativa na digestibilidade dos nutrientes.

This work was conducted with three assays. The first was carried out to estimate nutrient?s digestibility of coast cross hay (Cynodon dactylon cv. coastcross) with the total feces collection technique. The second assay was carried out to estimate nutrient?s digestibility of lucerne hay (Medicago sativa), coast cross hay, and peanut forage (Arachis pintoi) with the mobile bag technique. The last one was carried out to evaluate the prececal nutrient?s digestibility of the same forages used at second assay with the mobile bag technique in a horse cannulated at cecum. The two first assays were simultaneously, with four horses with average weight of 300kg fed coast cross hay only. Water and mineral salt was offered ad libitum. The nylon bags has 45? of porosity and 6.5x 3.0cm of internal dimension and were fill with 663 mg of forage samples ground at 1mm. These assays had duration of 19 days, 10 days for adaptation and regulation of intake, and the last five days to introduce the bags in the stomach and, bags collections in the feces. Two insertions of bags were made at day with 25 bags, eight bags per forage and one empty bag. The feces and the bags were kept on the floor quickly after the horses crap, the bags were separate and the time noted. The assay of prececal digestibility had duration of 20 days which the first 5 days were to horse adaptation and the last 15 days were to insert and recovery the bags in the cecum. In this assay the bags were similar of those used in the first assay, but with a little washer in the border of the bags to possibility the recovery them in the cecum with a magnet. The magnet was place into the cannula near the ileocaecal junction, and at every 30 minutes beginning one hour after bag?s insertion in the stomach, the magnet was withdraw and the bags was removed until 7 hours later. Values of total digestibility with feces collection and mobile bags were similar with the possibility to use the mobile bag technique as alternative to feces collection.

The experimental design was the completely randomised with five tretments and four repetitions of 15 broilers each. The treatments were constituted of the values of 0.680; 0.840; 1.000; 1.160 and 1.320% of total of lysine in the ration (0.586; 0.746; 0.906; 1.066 and 1.226% of digestible lysine). In the period form 35 to 70 days age the levels of lysine influenced the final live weight of the broilers and it was estimated the level in 1.130% which would afford the best final live weight (2630g). The level of 1.135% of lysine in the ration would result in a bigger gain of weight (1641g). The broilers presented a linear growth in the ration consumption and linear reduction in the efficiency of of lysine utilization with the increase of the lysine levels in the ration. It was estimated a value of 1.046% of total lysine (0,952% of diestible lysine) which would result in a best feed: gain ratio (2.98). In the period from 35 to 84 days age the following values were estimated: 1.189% of total lysine (1.095% of diestible lysine) to bigger live weight (3211g), 1.196% of total lysine (1.102% of diestible lysine) to bigger gain of weight (2220g) and 1.078% of total lysine (0.984% of diestible lysine) to best feed: gain ratio (3,28).The increasing levels of lysine in the ration resulted in a linear increase in the ingestion of lysine and linear reduction in the efficiency lysine utilization. In relation to the carcass characteristics of broilers slaughtered at 70 days age, quadractic effects on the live weight after fasting and on the absolute weight of the hot carcass, abdominal fat, breast, thigh+drumstick and wing were observed. The studied levels of lysine influenced quadracticly the yield of breast and back and the relative weight of abdominal fat and gizzard. The levels of lysine influenced quadracticly the breast and back yield and the relative weight of the abdominal fat and gizzard. Linear increases in the absolute weight of the back, heart, liver, cecos and feet and linear reduction in the absolute weight of the proventricle and in the relative weight of the small intestine were observed. In the period from 35 to 84 days age quadractic effects on the absolute weight of the hot carcass, carcass yield, breast thigh+drumstick and back, in the heart and in the small intestine were observed. Linear increases in the live weight after fasting, in the absolute weight of the wing and liver, in the breast and thigh+drumstick and a linear reduction in the relative weight of the proventricle were observed. The levels of lysine did not influenced the other studied parameters. It was estimated that the ration with the level of 1.160% of total lysine (1.066% of digestible lysine) determined the biggest rate of the gross margin average by liver weight and of the gross margin average by weight gain in both studied periods. After 35 days age it is recomended to the male broilers of slow growing raised in a free-range system ration with 1.135% of total lysine (1.041% of digestible lysine) and with 1.196% of total lysine (1.102% of digestible lysine) respectively, to the slaughter at 70 and at 84 days age. O experimento teve como objetivos avaliar os efeitos do n?vel de lisina na ra??o sobre o desempenho, caracter?stica de carca?a e indicadores econ?micos de frangos de corte machos de crescimento lento, criados em semiconfinamento, nos per?odos de 35 a 70 e 35 a 84 dias de idade. Foi adotado o delineamento inteiramente casualizado com cinco tratamentos e quatro repeti??es de 15 aves cada. Os tratamentos foram constitu?dos pelos valores de 0,680; 0,840; 1,000; 1,160 e 1,320% de lisina total na ra??o (0,586; 0,746; 0,906; 1,066 e 1,226% de lisina digest?vel). No per?odo de 35 a 70 dias de idade, os n?veis de lisina influenciaram no peso vivo final dos frangos sendo estimado o n?vel de 1,130% de lisina total que proporcionaria o melhor peso vivo (2630g). Para o ganho de peso o n?vel de 1,135% de lisina total na ra??o resultaria no maior ganho de peso (1641g). Os frangos apresentaram aumento linear no consumo de ra??o e redu??o linear na efici?ncia de utiliza??o de lisina com o aumento dos n?veis de lisina na ra??o. Para convers?o alimentar foi estimado em 1,046% lisina total (0,952% de lisina digest?vel) o valor que proporcionaria a melhor convers?o alimentar (2,98). No per?odo de 35 a 84 dias de idade foram estimados os seguintes valores de: 1,189% de lisina total (1,095 de lisina digest?vel) para maior peso vivo (3211g), 1,196% de lisina total (1,102% de lisina digest?vel) para maior ganho de peso (2220g) e 1,078% de lisina total (0,984 de lisina digest?vel) para melhor convers?o alimentar (3,28). Os n?veis crescentes de lisina nas ra??es resultaram em aumento linear na ingest?o de lisina e em redu??o linear na efici?ncia de utiliza??o de lisina. Quanto ?s caracter?sticas de carca?a de frangos abatidos aos 70 dias de idade, foram observados efeitos quadr?ticos sobre o peso vivo p?s o jejum e nos pesos absolutos da carca?a quente, da gordura abdominal, do peito, coxa+sobrecoxa e asa. Os n?veis de lisina pesquisados influenciaram de forma quadr?tica no rendimento do peito e dorso e nos pesos relativos da gordura abdominal e da moela. Foram observados aumentos lineares nos pesos absolutos do dorso, cora??o, f?gado, cecos e p?s e redu??es lineares nos pesos absolutos do proventr?culo e nos pesos relativos do proventr?culo e intestino delgado. No per?odo de 35 a 84 dias de idade, foram observados efeitos quadr?ticos sobre o peso absoluto da carca?a quente, rendimento de carca?a, no peito, coxa+sobrecoxa e dorso, no cora??o e no intestino delgado. Foram observados aumentos lineares no peso vivo p?s-jejum, nos pesos absolutos da asa e f?gado, nos rendimentos de peito e coxa+sobrecoxa e uma redu??o linear no peso relativo do proventr?culo. Os n?veis de lisina n?o influenciaram os demais par?metros estudados. Foi estimado que a ra??o com o n?vel de 1,160% de lisina total (1,066% de lisina digest?vel) determinou os maiores ?ndices de margem bruta m?dia por vivo e de margem bruta m?dia por ganho de peso, nos dois per?odos estudados. Para frangos de corte machos de crescimento lento e criados em semiconfinamento, recomenda-se ? partir dos 35 dias de idade, ra??o com 1,135% de lisina total (1,041% de lisina digest?vel) e com 1,196% de lisina total (1,102% de lisina digest?vel), respectivamente, para o abate aos 70 e aos 84 dias de idade.

Not just the mere transmission of knowledge. There is a need for action liberating, in which the teaching profession give rise to the task of educator. Thus, the technical-vocational education represents an alternative, because at the same time that teaches, ensures a profession. The objective of this research was improving knowledge in the field of education and understand the reality of vocational education, taking as the object of study the Agrot?cnica Federal School of Salinas. This study was conducted with the students of the second series of technical course in Agriculture. The methodology is based on qualitative research. A questionnaire was used by students, supervised by Professor advisor for the collection of information among family farmers. The council was divided into 05 regions, totaling 50 respondents. The search diagnosed the economic importance of the creation of pigs and the parameters evaluated were the profile of the interviewees, position in the process of agricultural production, current insertion in the labour market agricultural, socioeconomic and participation policy. Through the results, it was concluded that most respondents residing for a long time in the farm and are owners of the property. Although the sugar cane is cultivated by most producers it is not widely used as an alternative food for pigs. It assessed the participation of students in the search through a questionnaire aimed at assessing the importance of research for them and encourage them to basic scientific research. Another segment was the search done with pigs in the process of termination. The Escola Agrot?cnica, provided a complete cycle of pigs, facilitated the conduct of the trial. The objective of the research was to evaluate the effects of the replacement of 15% of sugar cane by the diet provided. The effects were studied performance, quality of the carcass, morphology of gastrointestinal tract and economic analysis. The study based on the inclusion of sugar cane in the diet of pigs, replacing 15% of the dry matter-of the diet, because by its energy wealth to sugar cane can be considered a viable alternative in the feeding of these animals. The ration provided to them was formulated in order to meet nutritional requirements. In performance were analyzed the consumption of diet, weight gain and feed conversion. The amount of feed given not caused reduction in the thickness of bacon and not influenced the weight of the digestive and other organs of finish pigs. Devido ? escassez de m?o-de-obra especializada no mercado de trabalho, ? necess?rio ministrar uma educa??o que estimule o estudante ? conquista de uma profiss?o. N?o basta a simples transmiss?o de conhecimentos. Torna-se necess?ria uma a??o libertadora, em que a profiss?o de professor ceda lugar ? miss?o de educador. Assim, o ensino t?cnico-profissionalizante representa uma alternativa, pois ao mesmo tempo em que ensina, garante uma profiss?o. O objetivo desta pesquisa foi aprimorar os conhecimentos na ?rea da educa??o e compreender a realidade educacional do ensino profissionalizante, tomando como objeto de estudo a Escola Agrot?cnica Federal de Salinas. O presente trabalho foi desenvolvido juntamente com os alunos das segundas s?ries do curso t?cnico em Agropecu?ria. A metodologia fundamentou-se na pesquisa qualitativa. Um question?rio foi utilizado pelos discentes, supervisionados pelo professor orientador, para a coleta de informa??es junto aos agricultores familiares. O munic?pio foi subdividido em 05 regi?es, totalizando 50 entrevistados. A pesquisa diagnosticou a import?ncia econ?mica da cria??o de su?nos e os par?metros avaliados foram: o perfil dos entrevistados, posi??o no processo de produ??o agropecu?ria, atual inser??o no mercado de trabalho agr?cola, n?vel socioecon?mico e participa??o pol?tica comunit?ria. Atrav?s dos resultados, concluiu-se que a maioria dos entrevistados reside h? muito tempo na fazenda e s?o propriet?rios dos im?veis. Embora a cana-de-a??car seja cultivada pela maioria dos produtores ela ? pouco utilizada como alternativa alimentar para su?nos. Foi avaliada a participa??o dos alunos na pesquisa atrav?s de um question?rio visando a avaliar a import?ncia da investiga??o para os mesmos e incentiv?-los a inicia??o cient?fica. Outro segmento foi ? pesquisa feita com su?nos em fase de termina??o. A Escola Agrot?cnica, provida de uma suinocultura de ciclo completo, facilitou a condu??o do experimento. O objetivo da pesquisa foi avaliar os efeitos da substitui??o de 15% de cana-de-a??car pela dieta fornecida. Os efeitos estudados foram: o desempenho, qualidade da carca?a, morfologia do trato gastrointestinal e an?lise econ?mica. O estudo fundamentou-se na inclus?o da cana-de-a??car na dieta alimentar dos su?nos, substituindo 15% da mat?ria-seca da dieta, porque pela sua riqueza energ?tica a cana-de-a??car pode ser considerada uma alternativa vi?vel na alimenta??o desses animais. A dieta fornecida a eles foi formulada de modo a atender ?s exig?ncias nutricionais. No desempenho, foram analisados o consumo de ra??o, ganho de peso e convers?o alimentar. A quantidade de dieta ministrada n?o ocasionou redu??o na espessura de toucinho e nem influenciou no peso dos ?rg?os digestivos e demais ?rg?os de su?nos em termina??o

It was used 20 crossbreed gilts, with 35 kg on average of live weight, in a randomized blocks experimental design with five treatments, and four blocks. The five levels of barley bagasse inclusion were 0, 12.5, 25, 37.5 and 50%, replacing the ration based on the dry matter of the reference ration (0% of inclusion). The performance variables ration intake (RI), barley bagasse intake (BBI), total feed intake (TFI), daily ration intake (DRI), daily barley bagasse intake (DBBI), daily feed intake (DFI), total body weight gain (TWG), daily body weight gain (DWG) and feed conversion (FC), also carcass characteristics and weights of organs and visceras were submitted to variance and polynomial regression analysis. It was observed linear reduction on RI and quadratic effect on all the other performance parameters evaluated. The BBI increased with the BB increasing level while TFI increased until 14.91% then decreasing after this level of inclusion. A quadratic effect was observed on DRI and DBBI while DFI increased until the level of 15.00% then decreasing after this level of inclusion. TWG and DWG increased until levels of 12.89 and 14.00% respectively, then decreasing after this level of inclusion. The FC improved progressively until 13.34% of inclusion then getting worse after this level of inclusion. Were evaluated: hot carcass weight (HCW), cold carcass weight (CCW), carcass length (CL) and carcass yields (CY), backfat thickness (BT), ham weight (HW) and ham yield (HY), palette weight (PW) and palette yield (PY), lomb weight (LW) and lomb yield (LY), and loin eye area (LEA). It was observed a quadratic effect on HCW and a linear reduction effect on PW and PY, as the level of barley bagasse inclusion was increased in the swines diets, with none influence on the other carcass characteristics. The Weights of gastro-intestinal tracts (GIT), viscera (VISC), stomach (SW) and liver (LW) were evaluated. There was not any influence on the weights of these last variables due to the level of BB in the growing phase diet. It was observed linear reduction in the feeding cost (FCT) and quadratic effect in the cost per unit of gain (CPUG), which decreased until 22.72% and increasing after this level of BB inclusion. The best level of BB inclusion in diets for swines in growing phase would be 14.91% for higher total DM intake, 12.89% for higher bodyweight gain and 13.34% for the best feed conversion. BB can be included in the growing diet up to 17,36%, without compromising the carcass quality of swines slaughtered at 100 kg of liveweight. BB can be included up to 22.72% in diets of swines in growing phase for reduction of the feeding costs. O presente trabalho foi realizado no Setor de Suinocultura do Instituto de Zootecnia da Universidade Federal Rural do Rio de Janeiro (FAIZ/UFRRJ), durante o per?odo de agosto a novembro de 2005, com o objetivo de avaliar diferentes n?veis de inclus?o de baga?o de cevada na dieta de su?nos em fase de crescimento, dos 35 aos 60 kg de peso vivo. Foram utilizados 20 animais mesti?os das ra?as Large White, Duroc e Landrace, f?meas com peso m?dio de 35 kg, distribu?dos em delineamento de blocos ao acaso com cinco tratamentos e quatro blocos. Os cinco n?veis de inclus?o de baga?o de cevada na dieta foram: 0%; 12,5%; 25%; 37,5% e 50%, substituindo a ra??o com base na mat?ria seca da ra??o refer?ncia (0% de inclus?o). Os par?metros de desempenho consumo de ra??o (CR), consumo de baga?o de cevada (CBC), consumo total (CT), consumo di?rio de ra??o (CDR), consumo di?rio de baga?o de cevada (CDBC), consumo di?rio (CD), ganho de peso total (GP), ganho de peso di?rio (GPD) e convers?o alimentar (CA), assim como caracter?sticas de carca?a e pesos dos ?rg?os e das v?sceras foram submetidos ? an?lise de vari?ncia e de regress?o. Observou-se redu??o linear no CR, e efeito quadr?tico sobre os demais par?metros de desempenho estudados. Observou-se efeito quadr?tico sobre o CBC com o aumento do n?vel de inclus?o, enquanto o CT aumentou at? o n?vel de 14,91% e reduziu ap?s esse n?vel de inclus?o. Observou-se efeito quadr?tico no CDR e no CDBC enquanto o CD aumentou at? o n?vel de 15,00% passando a diminuir ap?s esse n?vel de inclus?o. O GP e o GPD aumentaram at? o n?vel de 12,89 e 14,00% respectivamente, apresentando redu??o ap?s esse n?vel de inclus?o. A CA melhorou gradativamente com a inclus?o at? o n?vel de 13,34% passando a piorar ap?s esse n?vel de inclus?o. Foram avaliados: peso de carca?a quente (PCQ), peso de carca?a resfriada (PCR), comprimento de carca?a (CC) e rendimento de carca?a (RC), espessura de toucinho (ET), peso de pernil (PP) e rendimento de pernil (RP), peso de paleta (PPL) e rendimento de paleta (RPPL), peso de lombo (PL) e rendimento de lombo (RL), e ?rea de olho de lombo (AOL). Observou-se efeito quadr?tico no PCQ e efeito linear no PPL e no RPPL, ? medida que se aumentou o n?vel de baga?o de cevada na dieta dos su?nos, n?o tendo sido observado influ?ncia sobre os demais par?metros de carca?a. Foram avaliados os pesos de trato gastro-intestinal (TGI), das v?sceras (VISC), de est?mago (EST) e de f?gado (FIG). N?o houve influ?ncia do n?vel de baga?o de cevada na dieta dos su?nos em crescimento sobre esses par?metros. Observou-se redu??o linear no custo de alimenta??o (CAL) e efeito quadr?tico no custo por unidade de ganho (CPUG), observando-se redu??o em at? 22,72% no CPUG e aumento ap?s esse n?vel. O melhor n?vel de inclus?o de baga?o de cevada em dietas para su?nos em crescimento seria de 14,91%, para maior consumo total de MS, 12,89% para m?ximo ganho de peso e 13,34% para a melhor CA. O baga?o de cevada pode ser inclu?do na dieta de su?nos em fase de crescimento em n?veis de at? 17,36%, sem comprometer a qualidade de carca?a de su?nos abatidos aos 100 kg de peso vivo. O baga?o de cevada pode ser inclu?do na dieta de su?nos em fase de crescimento em n?veis de at? 22,72% para redu??o dos custos de alimenta??o.

Brazilian Apiculture is currently facing some obstacles to produce wooden hives. Regarding the similar physical properties within the wood, the hives made of cement-vermiculite mortar (CVM) have been tested in order to find out if it shows also similar biological responses to the wooden hives. This study took place in a tropical region ((22?45?28"S, 43?41?05"W), during eight months. Standard Langstroth hives (n=20) were built, and used in an apiary containing Africanized honeybees colonies from equal strength (one super) and queen line. The CVM boxes and colonies were compared with control one (wooden made) in a completely randomized design, with two factors (beginning and end of the study, with and without bees) and 5 repetitions/treatment, which were used in order to test the colony performance patterns: thermal control, flight activity, area of wax comb production and storage of food, weight of the super, honey collected and its chemical analysis. The standard CVM hive (2 supers) weights about 21.66 kg and its cost requirement (US$15.19) was 28.50% cheaper than the wooden hives cost. There were no significant differences between the hives performance. The honey quality sampled in both types of material followed the pattern of the schedule chemical analysis. Although the experiment time was restricted, the results allow us to recommend this new material (CVM) to small or poor beekeepers, to regions that need wood extraction prevention and to tropical regions. For it cannot be transported, the CVM hives must not be used for migratory activity. Hives made of cement-vermiculite mortar have been studied for two years now, and more time is needed to further observations. A vermiculita expandida ? um material isolante e muito utilizada pela engenharia. Nesta pesquisa, tendo como proposta a constru??o de caixas de abelhas com argamassa cimento-vermiculita (ACV), testou-se se este material apresenta respostas f?sicas e biol?gicas semelhantes ?s caixas constru?das de madeira. Esse estudo foi realizado em uma regi?o tropical (22?45?28"S, 43?41?05"W) durante oito meses. As caixas, modelo Langstroth, foram constru?das, instaladas e povoadas em um api?rio de col?nias de abelhas Africanizadas, com a mesma popula??o e parentesco da rainha. Acompanhou-se a temperatura interna, avaliou-se a condutividade t?rmica e a perda evaporativa das caixas de madeira e de ACV, n?o povoadas. Quando em col?nias, verificou-se seus padr?es de desempenho referentes ao controle t?rmico, da atividade de v?o, da ?rea de produ??o de favos e armazenamento de alimento, do peso da melgueira, do mel coletado e da sua qualidade qu?mica. As caixas e col?nias de ACV foram comparadas ?s de controle, de madeira, em um delineamento inteiramente casualizado, com dois n?veis de tratamento (tipo de material, in?cio e fim do estudo) e cinco repeti??es por tratamento, atrav?s da an?lise de vari?ncia. O peso da colm?ia padr?o ACV foi aproximadamente o dobro da de madeira e seu custo de US$15,19) foi 28,50% mais baixo que o da colm?ia de madeira. A temperatura m?dia interna das caixas e colm?ias de madeira e vermiculita foram semelhantes. Na caixa de ACV houve maior absor??o e perda mais r?pida de ?gua do que na de madeira. Apesar do controle t?rmico das col?nias de ACV, verificou-se que, eventualmente o intervalo da temperatura interna ultrapassou a faixa ?tima, o que pode ter ocasionado a redu??o da atividade de v?o, cuja diferen?a com a colm?ia de madeira foi significativa. A ?rea de forma??o de favos, de armazenamento de alimento e o peso do mel coletado n?o apresentaram diferen?as significativas, mas sofreram grande varia??o. A qualidade do mel amostrados nas colm?ias de ACV e madeira apresentaram-se dentro do padr?o rotineiro de an?lise qu?mica. Considerando-se que a caixa de ACV representa um modelo de constru??o artesanal, de baixo custo e caracter?sticas semelhantes ? caixa de madeira, sua utiliza??o torna-se mais uma alternativa vi?vel para o meio ap?cola, exceto para a atividade migrat?ria.
