Componentes de polpa e de semente de baru (Dipteryx alata Vog.), leguminosa do cerrado brasileiro, foram objetos de estudo neste trabalho. Análises térmicas, Termogravimetria (TG) e Calorimetria Exploratória Diferencial (DSC) foram utilizadas na investigação de proteínas em farinha desengordurada, concentrado e isolado proteico. A extração do concentrado proteico foi em pH 10, seguida de precipitação no ponto isoelétrico para obter o isolado, o qual foi seco por atomização. As curvas termogravimétricas foram obtidas em atmosfera de nitrogênio em vazão de 100 mL/minutos. As temperaturas iniciais, finais e de pico foram analisadas, assim como a perda de massa. Na faixa de temperatura avaliada, a farinha desengordurada e o concentrado apresentaram quatro etapas de perda de massa, enquanto que o isolado apenas duas etapas. O conteúdo de proteína da farinha desengordurada da semente de Baru foi mais alto do que do isolado. Por outro lado, ocorreu redução da entalpia, sugerindo que o processo aplicado na obtenção do concentrado e isolado de baru levou à desnaturação das proteínas.

Baru (Dipteryx alata Vog.), a species of legume found in the Brazilian savannas, was investigated in this study for the composition of its flesh and seed. Thermal analyses, Thermogravimetry (TG), and Differential Scanning Calorimetry (DSC) were used to investigate the proteins in defatted meal, concentrate, and protein isolate. The protein concentrate was extracted at pH 10, followed by a precipitation at the isoelectric point to obtain the isolate that was spray dried. The thermogravimetric curves were obtained under a nitrogen atmosphere with a 100 mL/minutes flow. The initial, final and peak temperatures and mass loss were analyzed. Within the performed temperature ranges studied, the defatted meal and concentrate presented four steps of mass loss, while the isolate showed only two steps. The protein content of defatted meal from Baru nuts was higher than that of the isolate. On the other hand, there was a reduction in enthalpy, which suggests that the process applied to obtain the baru concentrate and isolate led to protein denaturation.

The objective of this work was to evaluate, in bovines, the intake and apparent digestibility of nutrients, ingestive behaviour and content of total digestible nutrients (TDN) of diets based on sugar cane treated with calcium hydroxide. It was used four cows with average body weight of 412.06 kg ± 37.3 kg. The study included inclusion of calcium hydroxide at the doses 0, 8, 16 and 24 g/kg of sugar cane in natural matter basis fed in diets with 65% of roughage and 35% on concentrate, based on dry matter (DM). It was used a 4 × 4 Latin square experimental design with four treatments and four periods. Calcium hydroxide doses affected nutrient intake: DM intake was 7.88 kg/day at the dose of 14.99 g of calcium hydroxide, organic matter (OM) intake was 6.75 kg/day at 10.94 g; intake of neutral detergent fiber (NDF) of 3.33 kg/day with a dose of 13.93 g; and intake of acid detergent fiber (ADF) of 2.12 kg/day with a dose of 10.51 g. Digestibility coefficients showed a quadratic effect for doses of inclusion of calcium hydroxide. Dry matter digestibility was 72.88% with a dose of 11.65 g of calcium hydroxide, OM digestibility was 75.12% with 12.09 g; NDF digestibility was 58.67% with 12.11 g; ADF digestibility was 52.97% with 9.36 g and TDN digestibility was 71.42% with 10.92 g. There was no effect of the treatment for activities of rumination and total idle. Chewing time, number of bolus chewed and time for rumination of each bolli presented effect. Calcium hydroxide enabled greater intakes and digestibility of nutrients, especially from the cell wall, favoring the use of nutrients from the diet containing sugar cane, recommending a dose of 8-12 g.

Este artigo refere-se à importância da democracia nos processos geradores do desenvolvimento local nos assentamentos rurais. Os autores basearam-se no núcleo conceitual de desenvolvimento em concordância com instituições como Universidade de Quebec, Canadá, apontando o projeto de assentamento Andalúcia, estado de Mato Grosso do Sul, como um exemplo prático de democracia como um fator relevante para se desencadear o desabrochamento das potencialidades locais.

This article refers to the importance of democracy in the processes leading to local development in rural settlements. The authors were based on the conceptual core of development in accordance with institutions like the University of Quebec, Canada, pointing to the settlement project Andalúcia, state of Mato Grosso do Sul, as a practical example of democracy as a factor to trigger the unfolding local potential.
