El sistema agrícola bajo amenaza: ¿qué aportan los cultivos de cobertura y/o las pasturas cortas?
SNP o no SNP? Es está la cuestión?. (SNP, or not SNP? Is this the question?)
ABSTRACT. Genetic evaluations (GE) of commercial species have led to reached an efficient selection of the main economic relevant traits. Despite the great number of QTLs (quantitative trait loci) found in the last years, these have had limited application in formal breeding programs. However, the recent development of high density marker panel (SNP - single nucleotide polymorphism) has allowed the Genomic Selection (GS) application.

Water Productivity, Irrigation Management and Systematization for Rice Farming Systems in Central Region of Uruguay. Abstract.
A high proportion of rice farming irrigation in the Central Region of Uruguay is done with water stored in dams. Maximizing water productivity is important as savings in water inputs would reduce pumping irrigation costs, increase rice area planted and allows to allocate water to irrigate other crops in a rotation. The aim of the experiment is to determine irrigation management practices and systematization field layout techniques that increase Water Productivity, contemplating the economic and environmental sustainability of rice farming systems in Uruguay.
Water Productivity, Irrigation Management and Systematization for Rice Farming Systems in North Region of Uruguay. Abstract.
Rice farming systems in the North Region of Uruguay are mainly irrigated from water stored in dams. Increases in Water productivity would contribute to augment annually rice planted area, allows the allocation of water to irrigate other crops in a rotation and could contribute to reduce pumping irrigation costs. The aim of the experiments is to determine irrigation managem entpractices and field layout techniques that increase water productivity contemplating economic and environmental sustainability of rice farming systems in Uruguay.
Online prediction of fatty acid profiles in crossbred Limousin and Aberdeen Angus beef cattle using near infrared reflectance spectroscopy.
ABSTRACT The objective of this study was to examine the online use of near infrared reflectance (NIR) spectroscopy to estimate the concentration of individual and groups of fatty acids (FA) as well as intramuscular fat (IMF) in crossbred Aberdeen Angus (AA×) and Limousin (LIM×) cattle. This was achieved by direct application of a fibre-optic probe to the muscle immediately after exposing the meat surface in the abattoir at 48 h post mortem. Samples of M. longissimus thoracis from 88 AA× and 106 LIM× were scanned over the NIR spectral range from 350 to 1800 nm and samples of the M.
Associations between response to handling and growth and meat quality in frequently handled Bos taurus beef cattle.
ABSTRACT Fearful behavioral responses to handling (temperament) are undesirably associated with ADG and meat quality in infrequently handled Bos indicus cattle. It has never been assessed whether these relationships exist in calmer Bos taurus breeds in systems where handling is more frequent. Such systems predominate in some countries where beef production is a major agricultural activity.
Water Productivity, Irrigation Management and Systematization for Rice Farming Systems in Central Region of Uruguay. [Poster].
A high proportion of rice farming irrigation in the Central Region of Uruguay is done with water stored in dams (rainfall). Maximizing water productivity would :reduce the costs of pumping irrigation, increase rice area planted annually allow to irrigate other crops in a rotation.
