Degradabilidade ruminal da matéria seca de grãos de milho e de sorgo com alto ou baixo conteúdo de tanino processados

This work evaluated the effects of high moisture silage, extrusion and corn and sorghum drying with and without tannin, on the chemical composition and ruminal digestion of dry matter. The experimental design was completely randomized in 3x3 factorial scheme (kinds of grains: processing), for the chemical composition and degradability and three blocks (animals) through in situ method. It was verified significant difference between kinds of grains and processing in relation to the chemical composition, except for crude protein and mineral matter. The contents of etherextract in the three types of grains, were reduced significantly with the high moisture silage, extrusion and drying in relation to the humid material. For the contents of phenols, total and condensed tannin there was effect of hybrid, processing and interaction, and the most elevated contents were found in sorghum with tannin. Although grain composition has been similar, the interaction in ruminal ambient associated to the tannin, promoted differences in the dry matter degradability. It was concluded that sorghum without tannin may be ensiled or extruded, while the sorghum with tannin, must be extruded to improve the degradability and availability of nutrients.

́Toma que o filme é teú: Sai de Baixo entre o teleteatro e a sitcom

A program recorded in a theater, with the audience, incorporating all of the improvisations and later televised. That was Sai de Baixo, TV Globos program broadcasted between 1996 and 2002. However, a specific episode limit this article. Toma 0que o filmeéteu, 1998, was made alive. Was it a spasm of the old teleplay Or was it just a common sitcom episode To answer these questions, the paper used a case study, bibliographical and documentary research and concluded that this episode was not a brief return of teleplay, having in mind that the fact of being alive is not a requirement to be teleplay, but there are other criteria.

Fontes de carbono de baixo custo para a produção de xilanase termoestável por aspergillus niger

A strain of the flamentous fungus Aspergillus niger was isolated and shown to possess extracellular xylanolytic activity. These enzymes have biotechnological potential and can be employed in various industries. This fungus produced its highest xylanase activity in a medium made up of 0.1% CaCO3, 0.5% NaCl, 0.1% NH4Cl, 0.5% corn steep liquor and 1% carbon source, at pH 8.0. A low-cost hemicellulose residue (powdered corncob) proved to be an excellent inducer of the A. niger xylanolytic complex. Filtration of the crude culture medium with suspended kaolin was ideal for to clarify the extract and led to partial purifcation of the xylanolytic activity. The apparent molecular mass of the xylanase was about 32.3 kDa. Maximum enzyme activity occurred at pH 5.0 and 55-60oC. Apparent Km was 10.41 ± 0.282 mg/mL and Vmax was 3.32 ± 0.053 U/mg protein, with birchwood xylan as the substrate. Activation energy was 4.55 kcal/mol and half-life of the crude enzyme at 60oC was 30 minutes. Addition of 2% glucose to the culture medium supplemented with xylan repressed xylanase production, but in the presence of xylose the enzyme production was not affected.

Programação, conexão e avaliação de psicrômetro aspirado de termopar de baixo custo em micrologger para estudos agrometeorológicos

As the psychrometric method is considered standard for the measurement of relative humidity, many studies have used aspirated thermocouple psychrometers connected to microloggers but, however, they do not detail how the aspiration of the air stream is done. However, one of the major difficulties of aspirated thermocouple psychrometers is to program and to connect it in micrologger, because specific programming and connection are requires, and still some skills in getting accurate measurements. This work aimed to provide the programming and the connection of the aspirated thermocouple psychrometer type T for the CR10X microloggers and CR23X of Campbell Scientific, evaluating the quality of measurements of temperature and air relative humidity in relation the a sensor Vaisala HMP50. The non-continuous measurements were made in the period 2006/09/04 to 2007/07/11 at Jaboticabal, SP. The air temperature measurements were similar between the Vaisala sensors and aspirated thermocouple psychrometer, but the relative humidity measurements were significantly different. The measurements obtained by the aspirated thermocouple psychrometer connected to CR10X micrologger were the most accurate. Using the programming and connection of a micro-fan to suck in the dry and moist bulbs of aspirated thermocouple psychrometer in microloggers models CR10X and CR23X, it is possible to obtain measurements of air temperature with good precision and accuracy, and measurements of air relative humidity with good precision, but accuracy is not always attainable due to the difficulties inherent to the physical processes that occur in the wet bulb, the skill in the use and maintenance of this equipment and the reservoir protection against radiative effects.
