Mycobacterium paratuberculosis detection in cow's milk in Argentina by immunomagnetic separation-PCR
(Elsevier, 2016-06)The aim of this study was to standardize a diagnosis procedure to detect Mycobacterium avium subsp. paratuberculosis (Map) DNA in raw cow milk samples under field conditions. A procedure that combines both immunomagnetic ... -
Potential for crop production increase in Argentina through closure of existing yield gaps
(Elsevier, 2015-12)Favorable climate and soils for rainfed crop production, together with a relatively low population density, results in 70–90% of Argentina grain production being exported. No assessment to date has tried to estimate the ... -
Utilization of fluorescence spectroscopy as a novel approach to evaluate the oxidative stability in beef retail displayed
(Elsevier, 2016-09)Beef samples from grazing steers finished with different seed-supplemented diets were vacuum packaged for 3, 14 and 56 days (VC) and subsequently exposed to aerobic conditions (AE) for 0 and 5 days. Different fluorescent ... -
Ranges of Vigor Based on the Electrical Conductivity Test in Dehulled Sunflower Seeds
(Academic Journals, 2015)Electrical Conductivity (EC) is a promising vigor test since it produces fast laboratory results. In sunflower, the leakage of electrolytes from the pericarp may interfere with exudates from embryo tissues. The aims of ... -
Mid-Season High-Resolution Satellite Imagery for Forecasting Site-Specific Corn Yield
(MDPI, 2016-10)A timely and accurate crop yield forecast is crucial to make better decisions on crop management, marketing, and storage by assessing ahead and implementing based on expected crop performance. The objective of this study ... -
The phylogenetic structure of plant–pollinator networks increases with habitat size and isolation
(Wiley, 2016-01)Similarity among species in traits related to ecological interactions is frequently associated with common ancestry. Thus, closely related species usually interact with ecologically similar partners, which can be reinforced ... -
Improve intra‐uterine insemination in rabbits using ultra‐high temperature skim milk as extender to keep semen at room temperature
(Wiley, 2016-03)Two experiments were carried out to examine in vitro quality and in vivo fertility of rabbit semen diluted in ultra‐high temperature (UHT) skim milk. In the first experiment, pooled ejaculates of 10 adult rabbits were ... -
Temperature influence during seed filling on tocopherol concentration in a traditional sunflower hybrid
(Instituto de la Grasa, CSIC, 2007)Se investigó el efecto de la temperatura durante períodos cortos en el llenado de las semillas sobre la concentración de tocoferoles y la relación tocoferoles/ácido linoleico en un híbrido tradicional de girasol. Se realizó ... -
Comparative analysis of replicative properties of phylogenetically divergent, Argentinean BoHV-4 strains in cell lines from different origins
(Elsevier, 2019-06)Bovine gammaherpesvirus 4 (BoHV4) is a member of the family Herpesviridae. In Argentina, BoHV4 was isolated and characterized in 2007 from samples of aborted cows. Argentinean isolates are highly divergent and are classified ... -
Predicting soybean losses using carbon dioxide monitoring during storage in silo bags
(Elsevier, 2019-06)The rapid increase of the overall grain production of Argentina resulted with a storage capacity deficit in permanent structures of 40–50 million tons, and this context favored the rapid adoption of the silo bag technology. ... -
Cambios en las propiedades químicas de un suelo molisol de la región pampeana argentina con diferente historia de manejo = Changes on the chemical properties of a mollisol soil under different management systemas in the Pampean region, Argentina
(Universidad de Concepción, Chile, 2015)La intensificación del uso agrícola del suelo provoca degradación, la cual puede revertirse implementando rotaciones de cultivos, labranzas conservacionistas, forestaciones o incorporando pasturas. El objetivo de este ... -
Evaluación de indicadores de retención en sistemas agrícolas, ganaderos y forestales = Evaluation of phosphorus retention indicators in agricultural, livestock and forestry systems
(Universidad de Concepción, Chile, 2014)El escurrimiento, erosión o lavado del fósforo (P) del suelo aumentan con altas concentraciones de P extractable y condiciones que favorezcan su transporte. Los objetivos del presente trabajo fueron evaluar la relación ... -
Vaginal histological changes after using intravaginal sponges for oestrous synchronization in anoestrous ewes
(Wiley, 2015-04)To characterize the histological and cytological vaginal changes generated by the use of intravaginal sponge (IS) applied in oestrous synchronization treatments in ewes during mid‐non‐breeding season. Thirty‐five multiparous ... -
Developing integrated crop knowledge networks to advance candidate gene discovery
(Elsevier, 2016-12)The chances of raising crop productivity to enhance global food security would be greatly improved if we had a complete understanding of all the biological mechanisms that underpinned traits such as crop yield, disease ... -
Expression profile of genes as indicators of developmental competence and quality of in vitro fertilization and somatic cell nuclear transfer bovine embryos
(Plos One, 2014-09)Reproductive biotechnologies such as in vitro fertilization (IVF) and somatic cell nuclear transfer (SCNT) enable improved reproductive efficiency of animals. However, the birth rate of in vitro-derived embryos still lags ... -
Estimating the risk of groundwater contamination and environmental impact of pesticides in an agricultural basin in Argentina
(Springer Verlag, 2019-02)Due to the increase in pesticide detection in groundwater and other environmental components, some indicators, such as the attenuation factor (AF) and the environmental impact quotient (EIQ), have been proposed to determine ... -
Storage of WDGS under hermetic and non-hermetic conditions : effect on sensory properties, microorganisms, mycotoxins and nutritional value.
(Elsevier, 2019-01)WDGS production in Argentina substantially increased in the last 5 years and become a frequent constituent for feed diets. However, due to the extremely high moisture content of the product, quality deterioration occurs ... -
Reduced efficacy of fluazinam against Phytophthora infestans in the Netherlands
