37. Bakery waste in sheep diets: intake, digestibility, nitrogen balance and ruminal parameters
The objective of the study was to evaluate the effects of bakery waste inclusion (0; 25; 50; 75 and 100%, DM basis) in proportion to corn meal in the energetic mixture of the concentrate on intake, digestibility, nitrogen balance and ruminal parameters in sheep. Five male lambs with body weight of 30 kg were used in a 5 × 5 Latin square design. Experimental

38. Correlação entre precursores e voláteis em café arábica brasileiro processado pelas vias seca, semiúmida e úmida e discriminação através da análise por componentes principais
The influence of pre-processing of arabica coffee beans on the composition of volatile precursors including sugars, chlorogenic acids, phenolics, proteins, aminoacids, trigonelline and fatty acids was assessed and correlated with volatiles formed during roasting. Reducing sugars and free aminoacids were highest for natural coffees whereas total sugars, chlor

39. Caracterização do perfil de ácidos graxos em leite de cabra por diferentes métodos de extração de gordura ou por metilação direta / Characterization of fatty acids profile in goat milk using different fat extraction methods or by direct methylation
The objective of this research was to characterize the profile of fatty acids in goat milk by using four different methods of extraction of fat milk and a method of direct methylation for further analysis by gas chromatography. Samples were obtained from the storage tank of the caprine production systems of the Department of Animal Science at the Universidad

40. Influência do período de maturação e das estações do ano nos parâmetros físico-químicos e microbiológicos do queijo Minas artesanal da região do Serro
Minas traditional Serro cheese is a product that has a high consumption and appreciation in Brazil. The main objective of this work was to verify the ripening and dry and rainy seasons influence on hygienical-sanitary indicators, pathogenic microorganisms, Staphylococcal enterotoxins and physicochemical characteristics of this cheese to find out the microbio

41. ProduÃÃo de Ãcidos graxos volÃteis por biodigestÃo anaerÃbia da manipueira / Production of volatile fatty acids by anaerobic biodigestion of manipueira
The cultivation of cassava extends throughout Brazil because of its excellent adaptation to different soils and climatic conditions. Our country occupies the second position at the worldwide ranking in cultivating this plant (15% of the world production). The industrial processing of cassava generates a liquid waste, the so called manipueira, considered as a

42. Metabolic and biological prospecting of Coreopsis tinctoria
Coreopsis tinctoria Nutt., Asteraceae, flowering tops infusion has been traditionally used in many countries to control hyperglycaemia. In this work we report for the first time fatty acids and volatile compounds in this species. Fifteen fatty acids and sixteen volatile compounds were determined by GC-ITMS, being saturated fatty acids and monoterpenes the ma

44. Proposta de metodologia para determinação da atividade hidrogênica específica
Hydrogen production by fermentation process is influenced by the concentration and characteristics of organic substrate, the effluent pH value and biomass concentration. The determination of specific hydrogenic activity of organic substrates and biomass can be a tool to analyze the hydrogen volume produced during the fermentation, the volatile fatty acids pr

45. Effects of copper sources and levels on performance, Cu status, ruminal fermentation, metabolism and oxidation of lipids in cattle / Efeitos de diferentes fontes e níveis de cobre no desempenho, "status" de Cu, fermentação ruminal, metabolismo e oxidação de lipídios em bovinos
Copper is associated with lipid metabolism, becoming very important in reducing cholesterol, and with oxidative stability of meat, because it is part of some antioxidant enzymes. However, when in the ionic form, is considered a pro-oxidant element. The organic copper did not exhibit this effect and, besides, presents higher bioavailability than inorganic sou

46. Experimental determination of vapor-liquid equilibrium data of binary mixtures of fatty acids through Differential Scanning Calorimetry / Determinação experimental de dados de equilibrio liquido-vapor de misturas binarias de componentes de oleos vegetais atraves da calorimetria diferencial exploratoria
This work will contribute to some unpublished data of phase equilibria of compounds that form the biodiesel, which arouses the interest immediately. Vapor-liquid equilibrium (VLE) data for three binary mixtures of saturated fatty acids have been successfully measured through differential scanning calorimetry (DSC). These data are of great interest to the ind

47. Uma alternativa para a glicerina oriunda da produção do biodiesel : preparo de polióis e aplicação em adesivos poliuretânicos
This work reports the purification of the residual glycerin, a coproduct of the biodiesel production and their esterification with fatty acids from vegetable oils. The obtained products, mainly monoacylglycerides (polyols), were used for the preparation of urethanic adhesives. Firstly, residual glycerin was purified by vacuum distillation and the acid cataly

48. âAvaliaÃÃo morfolÃgica do abomaso e ceco-cÃlon de bovinosâ / Morphologic evaluation of abomasum and cecum-colon of bovines
The morphophysiology related to volatile fatty acids (VFA) absorption throughout the gastrointestinal tract of ruminants is not totally characterized. The elucidation of VFA behavior in all production and absorption sites can contribute to the adoption of nutritional strategies aiming to maximize food utilization and to reduce the occurrence of digestive dis
