Com o aumento progressivo da sobrevida em prematuros tem ocorrido um interesse crescente em rela??o a avalia??o nutricional, uma vez que uma alimenta??o adequada nas primeiras semanas de vida influencia o desenvolvimento a longo prazo. Portanto a avalia??o da composi??o corporal ? de fundamental import?ncia nos cuidados nutricionais dos prematuros. OBJETIVO: Avaliar a composi??o corporal atrav?s da Dual-energy X-ray absorptiometry em rec?m-nascidos prematuros alimentados com leite humano suplementado (FM85? .Nestl? Nutrition) ou leite humano. M?TODOS: Foram estudados 26 rec?m-nascidos prematuros com menos de 1500g de peso ao nascimento, durante a interna??o na UTI Neonatal do Hospital S?o Lucas da PUCRS, entre julho de 2006 e janeiro de 2010. Os rec?m-nascidos foram randomizados em dois grupos: o grupo 1 recebeu leite humano acrescido de FM85? e o grupo 2 que recebeu leite humano sem FM85?. Foram registrados as medidas antopom?tricas. A composi??o corporal foi avaliada atrav?s da Dual-energy X-ray absorptiometry. RESULTADOS: Foram comparados 15 rec?m-nascidos prematuros que utilizaram leite humano com FM85? e 11 que ingeriram apenas leite humano. Os dois grupos n?o apresentaram diferen?as significativas tanto na entrada como no final do estudo em rela??o a idade gestacional (m?dia 30,2 sem ? 2,38 versus 30 sem ? 1,62; p = 0,76), peso (1232,7 g ? 166,82 versus 1161,4 g ? 228,43; p = 0,37), comprimento (37,4 cm ? 1,9 versus 36,6 cm ? 2,65; p = 0,25) e per?metro cef?lico (26,5 cm ? 2,91 versus 25,9 cm ? 1,51; p = 0,5). As percentagens no in?cio e ao final do estudo n?o apresentaram diferen?a significativa de massa magra (80 ? 1,89 versus 80,3 ? 1,22; p = 0,63), massa gorda (19,6 ? 1,81 versus 19,4 ? 1,2; p = 0,72) e conte?do mineral ?sseo (0,4 ? 0,18 versus 0,3 ? 0,09; p = 0,18), O volume percentual de leite humano ingerido, e tempo de interna??o tamb?m foram semelhantes entre os dois grupos no momento da alta. A concentra??o mineral ?ssea/Kg do grupo FM85? foi maior no grupo do leite humano suplementado (5,46 ? 2,63 g/Kg versus 3,55 ? 1,54 g/Kg; p =0,04) ao final do estudo. CONCLUS?ES: N?o houve diferen?a entre os grupos em rela??o a massa magra, massa gorda e massa mineral ?ssea

This study aims to verify the change in body composition during the first year of post-bariatric surgery. METHODS: Was conducted a prospective observational cohort study. Were selected 50 patients with morbid obesity who underwent bariatric surgery and who kept up the care team according to the protocol during the first year after surgery. Patients were assessed preoperatively and postoperatively for periods of one, three, six and 12 months by tetrapolar bioelectrical impedance analysis and laboratory testing of lipids and serum albumin. Data were statistically analyzed. RESULTS: The variables of body composition obtained statistical significance (p <0.001), the mean and standard deviation in the pre and one year postoperatively, are respectively: BMI: 45,8?7,5 to 30,0?4,8 kg/m?; body fat: 64,7?15,5 to 30,6?9,8 kg, body fat percentage: 51,6?4,17 to 37,3?7,6%, total cholesterol: 197,1?49,8 to 169,8?31,0 mg/dl. The reduction in BMI achieved patients withdrew from the classification of morbid obesity to obesity grade I. The decrease in body fat percentage shows a better proportion between the body components. The percentage of fat decreased significantly more in males (p=0,012). The lean body mass (p=0,000) had the highest reduction in patients operated by the SUS (Unified Health System - Government of Brazil). CONCLUSION: The change in body composition of patients in the course of the first year of post-operative RYGBP assessed by tetrapolar BIA was statistically significant for all variables, demonstrating the effectiveness of the surgical procedure and the clinical protocol set, which tends to favor a better prognosis for the health and weight maintenance of patients in the long term. / INTRODU??O: ? conhecido o efeito potencial da cirurgia bari?trica na redu??o do peso corporal e na melhora das comorbidezes associadas, mas ainda ? pouco determinada a propor??o obtida entre os componentes do peso corporal. Este estudo tem por objetivo verificar a modifica??o da composi??o corporal durante o primeiro ano de p?s-operat?rio de cirurgia bari?trica. M?TODO: Foi realizado um estudo de coorte observacional prospectivo. Foram selecionados 50 pacientes obesos m?rbidos que foram submetidos ? cirurgia bari?trica e, que mantiveram acompanhamento conforme protocolo da equipe assistencial. Os pacientes foram avaliados no pr? e no p?s-operat?rio nos per?odos de um, tr?s, seis e 12 meses por bioimped?ncia tetrapolar e exames laboratoriais de l?pides e albumina s?rica. Os dados foram submetidos ? an?lise estat?stica. RESULTADOS: A altera??o da composi??o corporal apresentou signific?ncia estat?stica (p<0,001). Para as vari?veis apresentadas, os valores de m?dia e desvio padr?o nos per?odos pr? e de um ano p?s-operat?rio, s?o respectivamente: IMC (?ndice de massa corporal): 45,8?7,5 para 30,0?4,8 Kg/m?; gordura corporal: 64,7?15,5 para 30,6?9,8 Kg; percentual de gordura corporal: 51,6?4,17 para 37,3?7,6%; colesterol total: 197,1?49,8 para 169,8?31,0 mg/dl. A redu??o de IMC alcan?ada retirou os pacientes da classifica??o de obesidade m?rbida para obesidade grau I. Houve uma maior redu??o de percentual de gordura no sexo masculino (p=0,012). A massa magra corporal (p=0,000) obteve maior redu??o em pacientes operados pelo SUS (Sistema ?nico de Sa?de - Governo do Brasil). A diminui??o no percentual de gordura corporal demonstra uma melhor propor??o entre os componentes corporais. CONCLUS?O: A modifica??o na composi??o corporal dos pacientes no primeiro ano de p?s-operat?rio de cirurgia bari?trica, avaliada por bioimped?ncia tetrapolar, foi estatisticamente significante para todas as vari?veis analisadas, demonstrando efetividade do procedimento cir?rgico e do protocolo cl?nico institu?do, o que tende a favorecer um melhor progn?stico para a sa?de e para a manuten??o do peso destes pacientes ? longo prazo.

The study was carried out at the Forage and Pastures Sector, Animal Nutrition and Pastures Department, Animal Science Institute in Universidade Federal Rural do Rio de Janeiro, Serop?dica-RJ, Brazil between August and September 2013. Completely randomized design with a factorial arrangement of five (45% N) (0, 1, 2, 3 and 4% based on dry matter) commercial urea doses distributed in a split-plot at two periods (30 and 45 days) for the bags opening, with five replications each was employed. The ammoniated material was stored in (1 kg hay / bag) plastic bags, sealed and after opening, samples were collected for bromathological analysis. No dose effect, time and dose x time interaction for dry matter, ether extract, neutral detergent fiber, acid detergent fiber, hemicellulose, cellulose, lignin, acid detergent insoluble nitrogen, mineral matter, total carbohydrates, B2 fractions and carbohydrates fraction (P> 0.05) were reported. The variables crude protein, neutral detergent insoluble nitrogen and non-fibrous carbohydrates were influenced by urea doses. The ammoniation of Tifton 85 hay with urea at 1; 2; 3: 4% doses on dry matter might promote increases in crude protein and non-fibrous carbohydrates. However, cell wall constituents of the forage might not be altered, as well. / Objetivou-se neste trabalho avaliar as altera??es na composi??o bromatol?gica do feno de Tifton 85 (Cynodon spp) submetido a diferentes doses de ureia e per?odos de tratamento.

Most of the available evidences evaluate the association of environmental factors with body mass index, despite the known limitations of this evaluation. Objective: this paper objective is to analyze the associations between fat percentage and the risk factors from the prenatal period. Methods: It was studied 225 students aged 5-18 years from Porto Alegre and Canela using verbal communication. The participants and their officials answered questionnaires about demography, socioeconomic data, related to stress factors and the measurement of the percentage of fat through bioimpedance analysis. The associations between fat percentage and stress factors (inadequate gestational weight gain, maternal smoking, low birth weight, cesarean section, gestational birth age, duration of breastfeeding, sleep time in the first year of life, diagnosis of chronic diseases and use of corticoids in the first year of life and in the last 12 months) were evaluated using the unique variation and multivariable linear Generalized model. Results: Of the 225 subjects enrolled, 94 (42%) were male and the average age was 9 ? 3 years. The use of corticosteroids during the first year of life and in the last twelve months were the only factors that had a significant association with the fat percentage in the unique variation regression model (OR 1.29, 95% CI 1.01 to 1.49; P = 0.003; OR 1.30, 95% CI 1.09 -1.54; P = 0.002), respectively. In the multivariate model, only the use of corticosteroids in the last year remained significant (OR 2.98; 27.01 -7.00; P = 0.012). Conclusion: The use of corticosteroids is associated with excess fat percentage in children and adolescents. / Introdu??o: Durante o per?odo fetal e a primeira inf?ncia, o indiv?duo ? mais sucess?vel ? influ?ncia dos fatores ambientais que podem ter consequ?ncias permanentes para a sa?de, como a obesidade. A maioria das evid?ncias dispon?veis avaliou a associa??o dos fatores ambientais com o ?ndice de massa corporal, apesar das limita??es conhecidas desta avalia??o. Objetivo: analisar as poss?veis associa??es entre percentual de gordura e os fatores de risco desde o per?odo pr?-natal. M?todos: Foram inclu?dos 225 estudantes, com idades de 5 a 18 anos, de Porto Alegre e Canela, mediante a comunica??o verbal. Os participantes e os respons?veis responderam question?rios sobre dados demogr?ficos, socioecon?micos e relacionados aos fatores estressores e ? aferi??o do percentual de gordura atrav?s da an?lise da bioimped?ncia. As associa??es entre o percentual de gordura e os fatores estressores (ganho de peso gestacional inadequado, tabagismo materno, baixo peso ao nascer, ces?rea, idade gestacional do nascimento, tempo de amamenta??o, tempo de sono no primeiro ano de vida, diagn?stico de doen?as cr?nicas e uso de corticoide no primeiro ano de vida e nos ?ltimos 12 meses) foram avaliadas por meio do modelo de regress?o linear (Generalized linear model) univariado e multivari?vel. Resultados: Dos 225 participantes inclu?dos, 94 (42%) eram do sexo masculino, e a m?dia da idade foi de 9 ? 3 anos. A utiliza??o de corticoides durante o primeiro ano de vida e nos ?ltimos doze meses foram os ?nicos fatores que apresentaram uma associa??o significativa com o percentual gordura no modelo de regress?o univariada (OR 1,29; IC95% 1,01 ? 1,49; P=0,003; OR 1,30; IC95% 1,09 ?1,54; P=0,002), respectivamente. J? no modelo multivari?vel, apenas o uso de corticoides no ?ltimo ano permaneceu significativo (OR 2,98; 1.27 -7,00; P=0,012). Conclus?o: O uso de corticoides est? associado ao excesso de percentual de gordura nas crian?as e adolescentes.

From this modeling, the pubic expenditure was divided according to its classification (Current expenditures and capital expenditures) and according to the four main Functional categories (health, education, defense, transport and communication), and was Estimating a fixed-effects model (linear and non-linear) with a robust estimator to see the capacity of each component to influence the per capita growth rate of the economy. The results suggest that current expenditures have a economic growth, while capital expenditures have the relation. Expenditures on health, education, transportation and communication positive relationships in relation to economic growth, although it is observed the "size effect" in these variables when linear. / Esse trabalho avalia o impacto dos componentes dos gastos p??blicos na taxa de crescimento do produto, para os estados brasileiros entre 1994-2006, utilizando um modelo AK de crescimento end??geno com 3 argumentos, onde se sup??e como dado o estoque de capital privado e divide-se o gasto p??blico em dois tipos: um produtivo, ????1, e outro improdutivo, ????2. A partir dessa modelagem, o gasto p??bico foi dividido de acordo com sua classifica????o econ??mica (gastos correntes e gastos de capital) e de acordo com as 4 principais categorias funcionais (sa??de, educa????o, defesa, transporte e comunica????o), e, foi estimado um modelo de efeitos fixos (linear e n??o linear) com estimador robusto para ver a capacidade de cada componente influenciar a taxa de crescimento per capita da economia. Os resultados sugerem que os gastos correntes possuem uma rela????o negativa com o crescimento econ??mico, enquanto os gastos com capital possuem a rela????o inversa. Os gastos com sa??de, educa????o, transporte e comunica????o apresentam rela????es positivas em rela????o ao crescimento econ??mico, embora seja observ??vel o ???efeito tamanho??? nessas vari??veis quando analisadas de forma n??o linear.

They show minimal resilience levels and need antropogenic interference for rehabilitation in the regional context. In this study it was evaluated 5 reforestations with different species and functional properties (treatments) after a lapse of 13-years. In chapter 1 it was evaluated the development, horizontal structure and floristic composition of shrubby-arboreal stratum. In chapter 2 understory spontaneous regeneration and in chapter 3 similarity of floristic composition between rehabilitation and a spontaneous restored area (~ 40 years old) were determined. At reforestation sites with five different groups of species, floristic composition increased from 12 to 23 species, distributed on 12 families and 276 individuals, where Fabaceae was the major family. For spontaneous regeneration 3.554 individuals were surveyed (1.438 on winter and 2.116 at summer) and the most representative families were Asteraceae and Poaceae. At the restoration site, it was observed 967 individuals from spontaneous regeneration, and the most representative families were Asteraceae and Sapindaceae, showing that there is low similarity between rehabilitation and restoration environments. All treatments displayed advances in the environmental sustainability, but two combinations of species had different performances in the rehabilitation of the reclaimed areas. / ?reas de empr?stimo constituem ecossistemas onde o solo e partes do subsolo foram suprimidas.

The vine?s yield and wilting effect on the chemical composition and fermentative capacity of the sweet potatoes? vines have been evaluated, using a 7x2 factorial arrangement (genotypes ?X? vines wilted or not), a randomized block design with four replications. Genotypes differed on the SMP and DM, NDF, ADF, CEL, LIG, CS, NIDA and CIN contents. Wilting promoted an increase in DM, CP, NIDA and fibrous components and reduction in levels of soluble carbohydrates, making wilted vines of poorer quality. There was not observed effect of wilting on the fermentative ability of in natura or wilted vines. Genotypes BD-25, BD-08 and BD-23, had yields higher than 7.0 t ha-1, while the genotype BD-43, showed low levels of ADF. Besides these features, There have been analyzed the chemical-bromatological composition of the microbial population of sweet potato silage inoculated or not by means of a factorial arrangement 5x2 (genotype ?x? with or without inoculation). The silages with different genotypes differ in ADF, HEM, and pH values. The use of inoculum did not change the microbial population and the characteristics or nutritive value of silages, except for the pH value. In general, the silage produced by all genotypes has good nutritional characteristics, however, the silage genotype BD-43 stood out, showing low levels of ADF.

Pesquisa do Estado de Minas Gerais (FAPEMIG) / Objetivou-se com este trabalho avaliar o efeito da compacta??o do solo e diferentes doses de nitrog?nio no desenvolvimento, produtividade e qualidade de esp?cies forrageiras e nos atributos f?sicos do solo. Foram montados tr?s experimentos independentes em casa de vegeta??o com um delineamento em blocos casualizados, em um esquema fatorial duplo. Os experimentos foram com as tr?s esp?cies forrageiras - Bachiaria ruzizienses, Brachiaria brizantha cv. MG-5 Vit?ria e Panicum maximum cv. momba?a; os tratamentos: quatro Graus de Compacta??o (GC) ? 65%; 75%; 85% e 95% e quatro dose de adubo nitrogenado ? 0; 200; 250 e 300 Kg de N ha-1), com quatro repeti??es. O experimento foi conduzido em vasos em casa de vegeta??o localizada na UFVJM campus JK, em Diamantina-MG. No local de coleta do solo utilizado no experimento, foram coletadas amostras de aproximadamente 5 kg para a realiza??o do ensaio de Proctor normal, determinando-se a Densidade do solo e a Umidade para cada corpo de prova. Uma vez estipulado o GC, conhecendo a Densidade m?xima do solo e o volume do vaso, foi poss?vel calcular a massa de solo a ser colocada dentro dos vasos referente a cada GC. As amostras foram coletadas 90 dias ap?s semeadura, para realiza??o das avalia??es em laborat?rio. As vari?veis analisadas nas plantas foram: produ??o de massa verde (MV) e massa seca (MS) da parte a?rea, altura, volume da raiz, prote?na bruta (PB), fibra em detergente neutro (FDN), fibra em detergente ?cido (FDA) e lignina. Para a realiza??o do ensaio de Resist?ncia do solo ? penetra??o (RP), as amostras indeformadas foram trabalhadas e saturadas por um per?odo de 48 h, em seguida deu-se in?cio ?s leituras de RP. Realizou-se tamb?m a avalia??o de RP em vasos contendo solo compactado com GC de 95%, antes da semeadura; a modelagem foi feita ajustando um modelo exponencial de RP x umidade e foram comparados estatisticamente por um teste de identidade de modelos. Concluiu-se que a MV, MS da parte a?rea, a altura de plantas e o teor de prote?na bruta aumentaram linearmente com a aplica??o de nitrog?nio em todas as forrageiras estudadas. ? medida que se aumentam as doses de nitrog?nio, os teores de FDN e FDA em todas as forrageiras estudadas diminu?ram. Para o volume da raiz, a Brachiaria brizantha cv. MG-5 Vit?ria respondeu linearmente e positivamente ?s crescentes doses de nitrog?nio no solo compactado. Na avalia??o dos atributos f?sicos do solo, o solo cultivado com Brachiaria ruziziensis foi o que apresentou uma maior RP na umidade na capacidade de campo no grau de compacta??o de 95%. As tr?s esp?cies forrageiras t?m capacidade de al?vio da estrutura do solo compactado; por?m, a Brachiaria brizantha cv. MG-5 Vit?ria demonstrou ser a mais eficiente. / Disserta??o (Mestrado) ? Programa de P?s-Gradua??o em Produ??o Vegetal, Universidade Federal dos Vales do Jequitinhonha e Mucuri, 2014. / The objective of this study was to evaluate the effect of soil compaction and different doses of nitrogen, in the development, productivity and quality of forage species and in soil physical properties. Three independent experiments were performed in a greenhouse with a randomized block design, in a double factorial. The experiments were with three forage species Bachiaria ruzizienses, Brachiaria brizantha cv. MG-5 Vit?ria and Panicum maximum cv. momba?a: the treatments: Four Degrees of Compaction (GC) ? 65%; 75%; 85% and 95% and four doses of nitrogen fertilizer? 0; 200; 250 e 300 Kg de N ha-1), with four replications. The experiment was conducted in pots in a greenhouse located at UFVJM JK campus, Diamantina-MG. At the site of the soil sampling used in the experiment, samples of 5kg approximately were collected to perform the normal Proctor test, determining soil density and humidity for each specimen. Once stipulated the GC, knowing the maximum density of the soil and the pot volume, it was possible to calculate the mass of soil to be placed in the pots for each GC. The samples were collected 90 days after sowing, to carry out evaluations in the laboratory. The variables analyzed in plants were: green mass production (MV) and dry matter (MS) of the shoot, height, root volume, crude protein (PB), neutral detergent fiber (FDN), acid detergent fiber (FDA) and lignin. To carry out the soil penetration resistance test (RP), the undisturbed soil samples were worked and saturated for a period of 48 h, next we started the RP readings. It was also performed the evaluation of RP in pots containing compacted soil with a 95% GC, before sowing and the modeling was performed by adjusting an exponential model of RP x humidity and they were compared statistically by an identity test of models. It was concluded that the MV, MS of the shoot, height of plants and crude protein content increased linearly with the application of nitrogen in all the studied forages. As it increases the nitrogen levels, the levels of FDN and FDA in all studied forages decreased. For the root volume, the Brachiaria brizantha cv. MG-5 Vit?ria responded linearly and positively to increasing doses of nitrogen in compacted soil. In the evaluation of soil physical properties, the soil cultivated with Brachiaria ruziziensis was the one that presented a higher RP in humidity at field capacity in the degree of compaction of 95%. The three forage species have relief capacity of the compacted soil structure, however, the Brachiaria brizantha cv. MG-5 Vit?ria proved to be the most efficient one.

O experimento foi conduzido na Fazenda Experimental do Moura, pertencente ? Universidade Federal dos Vales do Jequitinhonha e Mucuri (UFVJM), localizada no Munic?pio de Curvelo, MG e as an?lises laboratoriais forma realizadas no Laborat?rio de Nutri??o Animal do Departamento de Zootecnia da UFVJM, Campus Diamantina, MG. Foi adotado um delineamento inteiramente casualizado em esquema fatorial 4 x 4, sendo quatro n?veis de adi??o do farelo de crambe (FC: 0; 5, 10 e 20%, com base na mat?ria natural) e quatro tempos de abertura dos silos (10; 20; 30; 60 dias ap?s a confec??o das silagens),com quatro repeti??es. Para a avalia??o da composi??o bromatol?gica usou-se: mat?ria seca (MS); mat?ria org?nica (MO), mat?ria mineral (MM), prote?na bruta (PB), extrato et?reo (EE), fibra em detergente neutro corrigida para cinzas e prote?na (FDNcp), fibra em detergente ?cido (FDA), carboidratos totais (CT), carboidratos n?o fibrosos (CNF) e nutrientes digest?veis totais calculados (NDTcalculado). Para o perfil fermentativo foram avaliados os valores da atividade de ?gua (Aw), potencial hidrogeni?nico (pH), condutividade el?trica (CE), carboidratos sol?veis (CHOs) e nitrog?nio amoniacal (N-NH3). Os dados foram submetidos ? an?lise de regress?o (P>0,05). Para vari?vel EE, foi observado efeito de dose e tempo (P>0,05). Para a intera??o dos fatores (n?veis de inclus?o do FC x tempo de abertura) observou-se efeito para MS, MM, PB, MO, FDNcp, FDA, CT, CNF, NDT calculado, CE, AW, CHOs, pH e N-NH3. A adi??o do farelo de crambe na ensilagem de cana-de-a??car promoveu melhorias na composi??o bromatol?gica, uma vez que houve eleva??o nos teores de MS, PB, CNF, al?m da redu??o nos componentes fibrosos (FDNcp e FDA), proporcionando assim um alimento de melhor qualidade. As altera??es promovidas pela adi??o do FC at? os 20% de inclus?o na ensilagem de cana n?o comprometeram o perfil fermentativo da massa ensilada. A inclus?o do FC ? indicada at? o n?vel de 10% (com base na mat?ria natural), uma vez que maiores inclus?es acarretam em aumento desfavor?vel da mat?ria seca, nitrog?nio amoniacal e redu??o dos teores de carboidratos sol?veis. A partir dos 30 dias ap?s ensilagem, o material ensilado j? apresentava tend?ncia ? estabiliza??o. / Disserta??o (Mestrado) ?

The experiment took place at the Experimental Farm of Moura, belonging to the Federal University of the Jequitinhonha and Mucuri Valleys (UFVJM), located in the municipality of Curvelo, MG and the laboratory analyzes performed at the Animal Nutrition Laboratory, Department of Animal Science UFVJM Campus Diamantina, MG. A completely randomized 4 x 4 factorial design was adopted, with four levels of addition of crambe meal (CM: 0, 5, 10 and 20%, based on natural materials) and four days of opening of silos (10; 20; 30; 60 days after the opening of silos), with four replicates. For the evaluation of the chemical composition was used: dry matter (DM), organic matter (OM), mineral matter (MM), crude protein (CP), ether extract (EE), neutral detergent fiber corrected for ash and protein (NDFap), acid detergent fiber (ADF), total carbohydrates (TC), non-fibrous carbohydrates (NCF) and total digestible nutrients calculated (TDN calculated. Regarding the fermentative profile were evaluated: water activity (AW), hydrogenionic potential (pH), electrical conductivity (EC), soluble carbohydrates (sCHT), ammonia-nitrogen concentration (N-NH3). Data were subjected to regression analysis (P> 0.05). For variable EE, only dose and time effect was observed (P> 0.05). For the factors? interaction (levels of inclusion of CM x opening time) was observed effect for MS, MM, CP, MO, NDFap, ADF, TC, NFC, TDN, CE, AW, sCHT, pH and N-NH3. The addition of crambe meal in sugarcane silage boosted the chemical composition, since there was an increase in DM, CP, NFC, and a reduction in fibrous components (NDFap and ADF), thus providing better quality food. The changes promoted by the addition of the FC to the 20% inclusion in cane silage did not affect the fermentation characteristics of silage. The inclusion of the FC is given to the level of 10% (based on natural matter), since larger inclusions lead in an unfavorable increase in dry matte, ammonia nitrogen and reduced levels of carbohydrates. From 30 days after ensiling, the ensiled material already presented tendency towards stabilization.

Fish were collected monthly in the year of 2012. During biometrics, portions of the digestive tract and of gonads were removed, fixed in formalin 10% and Bouin, respectively, for be submitted to histological processing by the techniques of hematoxylin-eosin. Stomach content analyzes were performed using the methods of Frequency of Occurrence and Volumetric and was calculated the repletion index. Throughout the study period were recorded a total of 49 species. The fish assemblages differed between sections monitoring, with the highest abundance, biomass and indices of richness and diversity in sections B, D and C. Already the excerpt A, showed higher values for dominance and equitability. In the cluster analysis according to the faunal similarity was observed the formation of three groups: group I formed by excerpts B and D, group II by excerpt C and group III formed by excerpt A. The assessment of reproductive stage revealed that the fish assemblages discarded by trawling are composed mainly of juveniles. Regarding the feeding ecology, the species Larimus breviceps, Menticirrhus littoralis and Pomadasys corvinaeformis characterized as carnivorous with tendency to carcinofagia. Already Conodon nobilis characterized as carnivorous with tendency to piscivory, but all proved generalist-opportunistic with increase of feeding activity during drought. The dendrogram of grouping of the species developed based on the food items used shows the formation of four groups: Group I consists of species that feed mainly of "gastropod" and "sediment"; group II of "teleost fish"; the group III of "crustacea" and group IV of "echinodermata" and "bivalve". The anatomical and histological characteristics of the digestive tract were consistent with the dietary habits of the analyzed species. In this context, the Costa Branca of Rio Grande do Norte can be considered a feeding site and recruitment for juveniles, which, opportunistically, utilize resources associated with the background / A composi??o da ictiofauna descartada pelo arrasto camaroeiro, sua fase reprodutiva e ecologia alimentar foram estudadas nas praias da Bacia Potiguar, Brasil. Os peixes foram coletados mensalmente, no ano de 2012. Durante as biometrias, por??es do tubo digest?rio e das g?nadas foram retiradas, fixadas em formol a 10% e Bouin, respectivamente, para serem submetidas ao tratamento histol?gico pelas t?cnicas de Hematoxilina-Eosina. Foram realizadas as an?lises de conte?do estomacal atrav?s dos M?todos de Frequ?ncia de Ocorr?ncia e Volum?trico e foi calculado o ?ndice de Reple??o. Ao longo do per?odo de estudo foram registrados um total de 49 esp?cies. As assembleias de peixes diferiram entre os trechos de monitoramento, com maior valor de abund?ncia, biomassa e dos ?ndices de riqueza e diversidade nos trechos B, C e D. J? o trecho A, apresentou maiores valores para domin?ncia e equitabilidade. Na an?lise de Cluster de acordo com a similaridade faun?stica, observou-se a forma??o de tr?s grupos: o grupo I formado pelos trechos B e D, o grupo II composto pelo trecho C e o grupo III formado pelo trecho A. A avalia??o do est?gio reprodutivo revelou que as assembleias de peixes descartadas pelos arrastos s?o compostas principalmente por juvenis. Em rela??o a ecologia alimentar, as esp?cies Larimus breviceps, Menticirrhus littoralis e Pomadasys corvinaeformis caracterizaram-se como carn?voras com tend?ncia a carcinofagia. J? Conodon nobilis caracterizou-se como carn?vora com tend?ncia a piscivoria, por?m todas se revelaram generalistas oportunistas e com maior atividade alimentar durante a estiagem. O dendograma de agrupamento das esp?cies com base nos itens alimentares ingeridos demonstrou a forma??o de quatro grupos: O grupo I composto por esp?cies que se alimentam principalmente de gastr?pode e sedimento ; o grupo II de tele?steo ; o grupo III de crustacea e o grupo IV de equinodermata e bivalve . As caracter?sticas morfohistol?gicas do tubo digest?rio das esp?cies analisadas mostraram-se consistentes com seus h?bitos alimentares. Assim, a Costa Branca do Rio Grande do Norte pode ser considerada um s?tio de alimenta??o e recrutamento para peixes juvenis, os quais se utilizam oportunisticamente de recursos associados com o fundo
