Consumo, digestibilidade e balanço de nitrogênio de cordeiros alimentados com alto teor de amido ou fibra solúvel em detergente neutro associados ao óleo de girassol

The aim of this study was to evaluate the effect of different carbohydrate sources associated with sunflower oil on intake, digestibility of nutrients and nitrogen balance in diets of lambs. Twenty lambs were used, assigned in a completely randomized design with a 2 x 2 factorial arrangement of treatments with two sources of neutral detergent soluble carbohydrate, starch and neutral detergent soluble fiber, with and without the inclusion of 4.2% sunflower oil. The dry matter intake was not affected by carbohydrate sources and the inclusion of oil. Diets with a high percentage of starch provided higher digestibility of dry matter, starch and ether extract. The different sources of carbohydrates had no interference on digestibility of organic matter, crude protein, neutral detergent soluble fiber, nonfiber carbohydrates, neutral detergent fiber, hemicellulose and acid detergent fiber. The addition of oil in the diets increased the digestibility of ether extract. The combination of 4.2% oil in the diet high in soluble neutral detergent fiber had no influence on the nutrient digestibility, otherwise, the addition of oil at high starch diet caused a significant reduction in the digestibility of organic matter, neutral detergent fiber, hemicellulose and nonfiber carbohydrates. The quantities of nitrogen intake, absorbed and retained, did not differ as sources of carbohydrates and oil inclusion in the diet. The association of 4.2 % sunflower oil to the different sources of carbohydrates in the diet does not affect consumption and nitrogen metabolism in lambs. The addition of 4.2 % oil in the diet with high starch (28% of DM diet) promotes reduction in digestibility of organic matter, of fibrous and nonfibrous carbohydrate in the diet.

O clima urbano de Assis/SP: estudo comparativo da temperatura e umidade relativa entre a cidade e o campo

It is known that the urban environment modifies the energy balance between the surface and the atmosphere, causing changes in temperature, relative humidity, among other things, opening the way for studies aimed at urban climatology. Based on the theme of urban climate, this research focuses on the city of Assis, located west of São Paulo. The generation of urban climate is a result of various factors, among which stand out: the use and different land use, the thermodynamic properties of buildings, number of buildings in the urban, socioeconomic activities, etc.. In general, this increases the temperature and reducing relative humidity, providing thermal discomfort. The rural environment is used for comparison studies to this theme by presenting different characteristics in relation to the structure, morphology and urban functionality. The main objective of this study is to determine the characteristics of temperature and humidity environments with the habits and occupations of the different soils in winter, at night, one inserted into the urban fabric of Assis and the other in the rural environment, to verify for evidence of changes in climatic elements because of urbanization. To collect the data will be used mini automatic weather stations that record data on temperature and humidity. For analysis of the results will be made between the data obtained in the city and the countryside, developing graphics application using Excel to tabulate the data. It was found that there were differences in the thermo-hygrometric data collection points, showing a specific urban climate in the city of Assis

Avaliação de qualidade de amidos de mandioca modificados utilizados na fabricação de pão de queijo

The food industry looks for new ways and strategies to standardize the marketing products in the customer market. The modification of the cornflour that are produced in the manufacturing of the cheese bread has been one of the these ways, since some raw materials that are used to make the cornflour present different features in each supplyed allotment. The present research had as a main purpose to analyse such features looking forward to improving the quality of the final product. Thus, some tests were done to verify the pH, humidity and acidity; it was checked the percentage of carbonyl and carboxylic groups and the power of expansion to five different allotments and to farina, for example: pre-gel, natural, expandex farina as the combination of the three cited kinds. After diversifying the allotments, different results were acquired, even to an unique kind of farina and it was not possible to correlate the results of acidity, the percentage of carbonyl and carboxylic groups and the power of expansion. The pH and humidity are proper for each kind of farina. This way, the raw materials that are used for each cheese bread manufacturing must be analysed in each allotment

Análise do teor de compostos fenólicos e de ligninas em diferentes órgãos vegetativos de espécies arbóreas nativas de diferentes grupos sucessionais

O sucesso do desenvolvimento da dinâmica das formações vegetais depende das relações estabelecidas entre as espécies vegetais com outros organismos e com o meio físico. Tais relações estão sujeitas a situações de estresse, podendo esse ser de caráter abiótico, como condições elevadas de radiação solar e temperatura e déficit hídrico ou de caráter biótico, como a herbivoria e o ataque de patógenos. Dessa maneira, em virtude à necessidade de um sistema de defesa, as plantas utilizam compostos químicos, como compostos fenólicos e ligninas, para se desenvolverem com proteção. Os compostos fenólicos são compostos oriundos do metabolismo secundário vegetal e ocorrem na parede celular dos tecidos vegetais, constituindo assim uma rápida linha de defesa vegetal a lesões e infecções e funcionando como substrato para atuação de enzimas de defesa como peroxidases e polifenoloxidases. Junto com a atuação dos compostos fenólicos, as ligninas fornecem à planta maior resistência mecânica e impermeabilidade suficiente aos vasos condutores do xilema, proporcionando, assim, desde um fundamental auxílio aos vegetais na conquista do ambiente terrestre até o estabelecimento de uma barreira protetora eficiente contra o ataque de microorganismos. Assim, por meio da extração e análise dos teores de compostos fenólicos e de ligninas de porção de raiz, caule, ápice caulinar e folhas maduras e imaturas de indivíduos de Erythrina speciosa Andrews, Eugenia uniflora L., Hevea brasiliensis M.

Produção de cerveja, utilizando méis de diferentes origens botânicas como adjuntos

This study aimed to produce beer, using different botanical origins of honeys (orange, eucalyptus and wild), as malt adjuncts, and their Physical-chemical and sensorial characterizations. The production was made with malt, water, hops and honey. All musts were adjusted to 12 Brix, and the concentration of honey in the formulation was 45% (based on the extract), except for the control (0%). The physical and chemical analysis were performed on malt (extract content), honey (pH, free acidity, lactonic acidity, total acidity, color, turbidity, extract content, moisture content, reducing sugar, total reducing sugar and sucrose) in wort (content extract, pH, color, turbidity, fermentability ,bitterness and total acidity) and beer apparent extract, apparent fermentability, real extract, real fermentability, alcohol content, pH, total acidity, total foam, foam density , bitterness, carbon dioxide, color and turbidity). Sensory analysis was performed by nine-points hedonic scale testing. The attributes evaluated were appearance, aroma, flavor and overall. The results were submitted to ANOVA and means compared by Tukey testing at a 5% of probability. Beer with honey as adjuncts’ had high fermentability and low content of fat, compared to the pure malt beer. The addition of honey as an adjunct did not affect the majority of the physical-chemical parameters, except for turbidity, whereas beer with honey showed the highest value for this feature, in addition, it has also presented their biterness differences the values for beer with honey were lower. The different types of honeys did not affect the acceptability of beer, however, the beer with honey showed greater acceptance between beer with malt and honey
