“…Its potential in broiler diets has already been established (Ncube et al, 2012a;Ncube, Hamudikuwanda, & Saidi, 2012b;Ncube, Saidi, & Halimani, 2015) but research supporting its use in broiler diets is still at its infancy. Most of the information available relate to its chemical composition (Reed et al, 2001;Odenyo et al, 2003;McSweeney et al, 2005;Mukandiwa et al, 2010;Gusha et al, 2013), appropriateness of processing techniques and harvesting stage for broiler feeding (Ncube et al, 2015) and effect on growth performance (Ncube et al, 2012a(Ncube et al, , 2012b. Not much has been established regarding its effect on the physiology of gastrointestinal organs.…”

“…The tree is adaptable to drought conditions (Dzowela, 1994) and produces up to 12.4 t Ha -1 of biomass (Preece & Brook, 1999). A number of scientists have reported reasonable crude protein levels from the leaf meal ranging from 19%-26.5% (Rubanza, Shem, Bakengesa, Ichinohe, & Fujihara, 2007;Odenyo et al, 2003;McSweeney et al, 2005;Mukandiwa, Mugabe, Halimani, & Hamudikuwanda, 2010;Ncube et al, 2012a;Gusha, Ngongoni, & Halimani, 2013), indicative of its potential use as a protein source. Its potential in broiler diets has already been established (Ncube et al, 2012a;Ncube, Hamudikuwanda, & Saidi, 2012b;Ncube, Saidi, & Halimani, 2015) but research supporting its use in broiler diets is still at its infancy.…”

The effect of A. angustissima leaf meal based diets on intestinal physiology and dressed carcass weight was investigated on 150 day old chicks. Three diets, 0, 5 and 10% A. angustissima were used in a three phase feeding programme. At days 14, 28 and 42, two birds from each replicate were slaughtered, dressed and weighed. The weights and lengths of the duodenum, jejunum and colon were measured. Approximately 1 cm specimen was taken from each organ, fixed in formalin and stained for histological analysis. Using a light microscopy, the digestive and absorptive properties of the tissues were assessed. Inclusion of A. angustissima leaf meal increased intestinal wall thickness, epithelial thickness, and villus height of the duodenum (P < 0.05). There was no effect on the proportional weight and length of the jejunum, jejunum villi height and villi width (P > 0.05) but jejunum wall thickness decreased with increasing levels of the leaf meal (P < 0.05). Leaf meal inclusion resulted in an increase in weight, intestinal wall and mucosal thickness of the colon (P < 0.05) and a decline in sub-mucosal fold height and haustra coli width of the colon (P < 0.05). Dressed weight was the same across diets at two weeks (P > 0.05). At four and six weeks, broilers on the control and 5% diet had superior dressed weights to the 10% fed broilers (P < 0.05). It was concluded that for intestinal physiological adaptation that will not compromise weight gain in broilers, up to 5% A. angustissima could be included in broiler diets.

“…Dessas leguminosas, a G. sepium e a L. leucocephala, por serem palatáveis (Nair et al, 1984;Franco & Souto, 1986;Souto et al, 1992;Rangel et al, 2001;Toral & Simon, 2001;Zoby, 2001;Dias et al, 2004) e apresentarem níveis baixos de tanino (Nozella, 2001;Serisinhe & Iben, 2003;Hindrichsen et al, 2004;McSweeney et al, 2005), são recomendadas para bancos de proteína. Entretanto, a G. sepium foi considerada por Mendonça (2005) como de baixa palatabilidade como forragem verde, em razão da relutância dos animais em consumi-la, o que exigiu por isso um período de adaptação à dieta.…”

“…Ash (1990) e Hindrichsen et al (2004) afirmam que o sucesso da introdução das mudas de uma espécie arbórea, sem proteção e em presença de animais, depende do grau de sua aceitabilidade pelos animais, da velocidade de crescimento e da capacidade de competição com a gramínea na pastagem. Segundo Seresinhe & Iben (2003) McSweeney et al (2005), a aceitabilidade das forrageiras pode ser explicada pelo teor de tanino dessas leguminosas e, também, pelo fato de elas fazerem parte da dieta dos animais na pastagem (Souto et al, 1975).…”

Resumo -O objetivo deste trabalho foi analisar, por meio de métodos de análise de variância multivariada, o comportamento de 16 espécies de leguminosas arbóreas, introduzidas em pastagem estabelecida de Brachiaria decumbens, a partir de mudas pequenas e em presença de animais, em quatro épocas do ano, em Seropédica, RJ. Nove variáveis relacionadas ao comprimento e ao número de brotos das mudas, antes e após o pastejo dos animais, foram utilizadas nas avaliações. As diferenças estatísticas entre as médias da variável canônica principal, pelo teste de Scott-Knott, indicaram a formação de quatro agrupamentos, tendo-se destacado o grupo formado pelos tratamentos Mimosa tenuiflora nas 3 a e 4 a avaliações. Diferenças entre as médias dos tratamentos, para cada variável, calculadas por meio de intervalos de confiança de Bonferroni, mostraram que o maior comprimento e o maior número de brotos na muda, após o pastejo, foram encontrados na M. tenuiflora. Esta leguminosa é indicada para ser introduzida, com maior probabilidade de sucesso, nas pastagens de B. decumbens na região, sem a proteção das mudas e em presença de gado.Termos para indexação: variável canônica, aceitabilidade, sistemas silvipastoris. Performance of leguminous trees introduced into pasturesAbstract -The objective of this work was to analyse, by means of multivariate variance analysis, the behaviour of 16 leguminous tree species introduced into pastures of Brachiaria decumbens from unprotected young plants and under grazing, in four periods of the year, in Seropédica, RJ, Brazil. Nine variables, related to length and to number of sprouting, before and after animal grazing, were used for the evaluation. The statistical difference of the means of the principal canonical variable, calculated by the Scott-Knott test, indicated the formation of four groups, and the Mimosa tenuiflora group stood out at the 3 rd and 4 th evaluations. Difference among treatment means for each variable, calculated by Bonferroni confidence intervals, showed that the greatest sprouting length and the highest number of sprouting, after grazing, were found in M. tenuiflora. This leguminous species is indicated to be introduced into B. decumbens pasture of the region, with higher probability of success, without protection of the young plants and under grazing.Index terms: canonical variable, acceptability, silvipastural systems. IntroduçãoEm regiões tropicais e subtropicais, fica cada vez mais evidente que espécies arbóreas são necessárias para melhorar a produção, a qualidade e a sustentabilidade das pastagens (Alonzo, 2000;Costa et al., 2005), para assim acumular quantidades substanciais de carbono (Kanninen, 2001), aumentar a biodiversidade (Naranjo, 2000), além de se obter efeito maior, no caso de leguminosas arbóreas que possuem a capacidade de fixar o nitrogênio do ar por meio de associações simbióticas com bactérias nodulantes (Dias, 2005).Segundo Andrade et al. (2002), entre as razões de muitos pecuaristas considerarem inviável a presença de árvores nas pastagens, destacam-se...

“…The importance of these biochemical compounds has been recorded by various scientists (Kalita et al, 2007;Hussain et al, 2009). Besides these nutrients, the moisture, fiber, and ash contents and the energy values of individual plant species have also been regarded important to the human health (Cummings et al, 2004;Mcsweeney et al, 2005;Hussain et al, 2010).…”

The chemical composition of four edible plant foods species, three fish species and one prawn were analyzed in Food Chemistry Laboratory of Behbahan Khatam Alanbia University of Technology, Behbahan, Iran in 2014. The analysis of fatty acid and sugars composition were performed by gas liquid chromatography and high performance liquid chromatography, respectively. Protein and lipid content were founded higher in baked and fried in fish S. commersonnianus (74.29%), (20.20%), fish Sphyraena helleri (88.12%) and (17.77%), respectively. Ash content in fish S. commersonnianus varies from 9.80% to 15.34%, and in fish S. helleri from 5.83% to 7.68%. Based on the proximate analysis, it can be calculated that an edible portion of 100 g of studied edible plant foods provides, on average, around 303.9±1.04 kcal. The plant Portulaca neglecta is suitable for high temperature food processes. The macronutrient profile in general revealed that the wild plant foods were with rich sources of protein and carbohydrates, and had low amounts of fat. The highest protein, the lowest fat and energy contents were found in boiled in both fish species; therefore, boiling can be recommended as the best cooking method for healthy diet.
