Empirical attributes and limitations of methodologies for predicting the degradability of ruminal protein Ciencia e Investigación Agraria
Velásquez,Alejandro; Rivero,Jordana; Marnet,Pierre-Guy.
The object of the present review is to analyze the methodologies that are commonly used to estimate protein degradability in the rumen, focusing on their attributes and limitations to offer suggestions for improving their use. This information is essential for selecting food types when formulating feed diets. A reliable prediction of the digestibility of ruminal proteins is basic information necessary for optimizing the use of nitrogenous sources because digestibility can translate, on the one hand, into higher yields of milk, milk protein, meat or wool and, on the other hand, into lower excretion of nitrogenous compounds into the environment; it also has an impact on animal health and welfare. Traditionally, the digestibility of feed proteins in the rumen...

Metodologías de Estimación de Rendimientos en el Programa de Producción Agrícola : el caso del PRONESPRE en 2004-2006 en el Estado de México Colegio de Postgraduados
Serrano Carrillo, Esteban Justino.
En el Estado de México, en los últimos años el problema principal que enfrentan tanto las dependencias federales y estatales del sector agropecuario, es la carencia de información real sobre el medio rural y específicamente sobre la superficie sembrada de maíz y el volumen de producción que se obtiene; lo que origina una falta de elementos para la planeación. Por ello los objetivos de esta tesis es desarrollar y difundir la importancia que tienen los Sistemas de Información Geográfica (SIG) en los pronósticos de estimación de rendimiento y producción, recordando que la predicción de cosecha permite tomar decisiones razonables para el manejo de excedentes de producción, cupos de importación, orientación de apoyos a la comercialización y asistencia a...

The oceans play a key role in global issues such as climate change, food security, and human health. Given their vast dimensions and internal complexity, efficient monitoring and predicting of the planet's ocean must be a collaborative effort of both regional and global scale. A first and foremost requirement for such collaborative ocean observing is the need to follow well-defined and reproducible methods across activities: from strategies for structuring observing systems, sensor deployment and usage, and the generation of data and information products, to ethical and governance aspects when executing ocean observing. To meet the urgent, planet-wide challenges we face, methods across all aspects of ocean observing should be broadly adopted by the ocean...
