Viabilidade econômica da utilização dos resíduos da bananicultura na alimentação de cordeiros confinados

Aimed to analyze the economic feasibility of replacing hay Cynodon spp by hay banana crop residues in diet of lambs. We used 25 Santa Inês lambs, with an average age of five months and an average initial weight of 26.5kg, distributed in a completely randomized design with five treatments (40% hay Cynodon spp. + 60% concentrate, 20% hay banana leaf and 20% of Cynodon spp. + 60% concentrate, 40% of banana leaf hay + 60% concentrate, 20% hay pseudostem of banana and 20% of Cynodon spp. + 60% concentrate, 40% hay pseudostem of banana + 60% concentrate). After 69 days of experiment the animals were slaughtered. Possession of the cost of each diet and consumption of animals was calculated economic feasibility. Treatment with 40% of banana leaf hay + 60% concentrate showed the best economic indicators, based on the highest net income, the higher rate of return to higher profitability and marketing of live animals or slaughtered. The inclusion of banana crop residues in the diet of growing lambs increases the economic viability of the activity.

Análise comparativa da expressão de RNAm de aquaporinas em sapos hidratados e submetidos ao estresse hídrico

A maior parte das espécies de anuros adultos terrestres está constantemente exposta a altas taxas de perda de água por evaporação através da pele. A manutenção do balanço hídrico nestes animais envolve a absorção de água através da mancha pélvica, uma região da pele ventral altamente permeável à água, além da reabsorção de água a partir do fluido filtrado nos glomérulos ao longo do sistema tubular dos néfrons, bem como a partir da urina formada e estocada na bexiga urinária, em resposta à arginina vasotocina (AVT). O movimento de água através da membrana plasmática ocorre através de poros formados por proteínas integrais de membrana, conhecidas como aquaporinas (AQPs), e a regulação osmótica exercida pelo AVT envolve translocação de vesículas contendo AQPs do citoplasma para a membrana apical e, provavelmente, alteração na expressão de alguns tipos de AQPs. Resultados previamente obtidos no laboratório demonstraram a existência de variação interespecífica nas taxas de reidratação de três espécies de Rhinella, sendo que R. ornata apresentou taxas de reidratação significativamente menores que aquelas apresentadas por R. schneideri e R. icterica. Uma possível explicação para esta variação em taxas de reidratação poderia envolver diferenças na expressão de aquaporinas na mancha pélvica. Desta forma, o objetivo do projeto foi identificar e quantificar a expressão do RNAm de aquaporinas do tipo 1 (AQP-1) e de aquaporinas AVT dependentes pertencentes ao tipo 2a (AQP-t2 e AQP-t3) - quanto à classificação das AQPs entenda-se AQP -t aquelas que apresentam sequência gênica referentes a Rinella marina AQP -h a Hyla japonica.- nos seguintes tecidos: pele dorsal e pele ventral (mancha pélvica) de espécimes de R. schneideri e R. ornata totalmente hidratados e após submissão à desidratação correspondente a 70% da massa corpórea padrão. As hipótese ...

Fibras naturais: características químicas e potenciais aplicações

This study has as objective determining the chemical properties that serve as the basis for potential scientific and technological applications of seven species of fibrous plants cultivated in Brazil, which are: Banana” (Musa spp.), “Coco” (Cocos nucifera), Curauá (Ananas erectifolius), Fique (Furcraea andina), Piteira” (Furcraea gigantea), Sisal(Agave sisalana) and “Taboa” (Typha domingensis). The tests for determining the percent dry completely, extractives soluble in cold water, in hot water, in sodium hydroxide 1% and in ethanol-toluene, and the percentages of ash, hydrophobicity, lignin, holocellulose and cellulose were performed at the Department of Environmental Sciences, Agronomy College (FCA) of UNESP – Botucatu, São Paulo State. It also presents a literature review about these fibers and their potential applications. Differences between the results obtained and those found by other authors are possibly explained by variations on the origin of plant material, the harvest season, the climate and soil where they were grown. However, the results and the methodology used, serve as a basis for further studies with natural fibers

A multiplicidade poética de Emílio Moura: o encanto da hora amarga

The modernist poet Emílio Moura (1902-1971) incorporates a strictly modern language regarding the imagistic suggesting a mainly poetry metalinguistic. That way, from the works Canto da hora amarga (1932) and Cancioneiro (1944) we attest, through the poetic analysis, that modernity Moura’s poetry takes place in confluences with ideas ranging from biblical tradition and come to the depersonalization of the modern I and questing. We objectify, therefore, demonstrate and explore the metalinguistic and intertextual character that results in the personification of poetry, as clarified muse. To achieve this, this same poetry undergoes a dualistic and pessimistic sentiment, baroque, the I that is divided into life and death, light and shadow; goes through a romantic feeling of anguish and desolation and reaches the multiplicity of the poetic speaker, which promotes a constant struggle with the language. More than draw a correlation between classical and modern ideas (in the sense that the poet creates depersonalization and appropriates of free, short prose or verse, typical of modernism), intend to supply, at least in part, the dearth of studies on the miner poet who has found fertile ground to question and analyze internally the role of poetry in the multiplicity of man and modern society to therefore conclude that universalism the Emílio Moura becomes distinctive and mature. Thus, we will check how poetic inflows corroborate both works for reevaluation and critical insertion of poetic the Emílio Moura in the context of modern/Modernist Brazilian literature

Phytotherapy in the control of helminthiasis in production animals

Parasitic diseases constitute one of the main problems affecting livestock; however the use of chemical medicaments provides drug resistance residues in animal and environmental contamination. Changes in production concepts require that food must be produced in hygienic conditions, per healthy animals and that are not eliminating antibiotic residues, pesticides or other drugs. This scenario has favored organic production and the use of medicinal plants. For the control of endoparasites, several studies have published the benefits of Azadirachta indica A. Juss., Punica granatum Linn., Musa sp., Operculina hamiltonii G. DON., propolis, among others. However, despite the existence in- vitro studies that demonstrate the pharmacological properties of phytotherapics, there is still need for clinical trials to determine dosage and its effects in- vivo. Investigations of new bioactive natural substances can be of great value for the control of animal health and food safety, which is particularly important for organic production systems in which the use of chemical drugs is a limiting factor for certification.

O fantástico de Charles Nodier: lenda e mito

O artigo centra-se na análise do conto de Charles Nodier, “La légende de soeur Béatrix”, sob a perspectiva do fantástico literário; na criação de seu texto ficcional, o autor parte de uma lenda hagiográfica que acaba por mesclar-se a mitos antigos, associando o mito mariano ao da deusa grega Perséfone. Metáfora da poesia e da musa que caminha entre os dois mitos, a personagem do conto, irmã Béatrix, mostra que a encarnação é o caminho para o reavivamento do mito e da poesia.

Desenvolvimento micelial de Lentinula edodes em meios de cultivo à base de diferentes substratos orgânicos

The radial mycelial growth of Lentinula edodes (Berk.) Pegler, strain LE-96/13, was studied in culture media prepared with organic residues extract, by using substrates prepared with pineapple (Ananas comosus (L.) Merril) crown, Astrocaryum aculeatum Meyer peel, Theobroma grandiflorum Schum shell, Musa sp. (genomic group AAB, subgroup Pacovan) peel, and Musa sp. (genomic group AAB, subgroup Prata) peel, with three supplementation levels with wheat bran (0, 10 and 20%), and incubated at 25ºC. The experimental design was totally randomized, in a 5×3 factorial scheme, adding up 15 treatments with 4 repetitions, and each repetition corresponding to a Petri dish. The diameter of the colony was evaluated daily during nine days of incubation. After that period, it was verified that the highest mycelial growth averages of strain LE-96/13 of L. edodes were found in culture media prepared with T. grandiflorum Schum shell (whose supplementation with wheat bran was favorable for Mushroom development) and A. aculeatum Meyer peel (whose supplementation did not favor the mycelial growth of L. edodes in relation to the medium not supplemented).
