(2015-06-15)En silvicultura clonal, a fin de dar respuesta a situaciones de sitio o mercado específicas, es habitual la utilización de híbridos interespecíficos. La propagación vegetativa de estos materiales depende de la capacidad ... -
Molecular Characterization of the First Bovine Herpesvirus 4 (BoHV-4) Strains Isolated from In Vitro Bovine Embryos production in Argentina
(Plos One, 2015-07-15)Bovine herpesvirus 4 (BoHV-4) is increasingly considered as responsible for various problems of the reproductive tract. The virus infects mainly blood mononuclear cells and displays specific tropism for vascular endothelia, ... -
Animal performance, carcass characteristics and beef fatty acid profile of grazing steers supplemented with corn grain and increasing amounts of flaxseed at two animal weights during finishing
(Elsevier, 2015-08)The objective of this study was to determine (1) the effects of increasing flaxseed addition to the corn grain supplemented at finishing to grazing steers on animal performance, carcass characteristics and longissimus ... -
Temperature impact on the forage quality of two wheat cultivars with contrasting capacity to accumulate sugars
(2015-08-17)Wheat is increasingly used as a dual-purpose crop (for forage and grain production) worldwide. Plants encounter low temperatures in winter, which commonly results in sugar accumulation. High sugar levels might have a ... -
Quality assessment of irrigation water under a combination of rain and irrigation
(Elsevier, 2015-09)Supplementary irrigation is one of the proposed management practices to increase the area under grain production mainly in the Humid Pampas (HP). The most common source of irrigation water in the HP comes from groundwater ... -
Soybean and wheat response to lime in no-till Argentinean mollisols
(Elsevier, 2015-09)Crop production in Argentina has significantly increased over the past few years; this increase was consequence of better management practices which included P and N fertilization and, occasionally, S fertilization. Commonly ... -
¿El análisis de suelo permite diagnosticar la deficiencia de zinc en el cultivo de maíz?
(2015-09)El desarrollo de métodos adecuados de diagnóstico para evaluar la disponibilidad de Zn es clave para un manejo racional del mismo. El extractante más utilizado es el ácido dietilen triamino penta acético (DTPA) propuesto por ... -
Llama (Lama glama) semen collection via thermo-electric artificial vagina: effect of seasonality and collection interval on ejaculate characteristics
(Elsevier, 2015-09-09)Adult male Llamas (Lama glama) (n = 6) were collected using a receptive female and a thermo-electric artificial vagina assembled with a polyethylene collection bag with the following objectives: (a) to develop a reliable ... -
Sistemas de cultivo alternativos desarrollados por productores en el sudeste de la provincia de Buenos Aires
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2015-10-21)El proceso de expansión de la soja (denominado sojización) en la pampa argentina ha tenido como consecuencia la especialización de numerosas explotaciones agrícolas en el cultivo de soja. Sin embargo, muchos actores del ... -
Antioxidant effect of lemon balm (Melissa officinalis) and mate tea (Ilex paraguensys) on quality, lipid peroxidation and DNA oxidation of cryopreserved boar epididymal spermatozoa
(Wiley, 2015-11)In this study, we investigated the protective ability of the addition of two antioxidant herb extracts, mate tea and lemon balm, on boar epididymal frozen–thawed spermatozoa quality. Testes from mature boars were collected ... -
Birth of live llama (Lama glama) derived from embryo transfer storage at 5 °C for 24 h
(2015-11)The objective of the present work was to evaluate the efficacy of maintaining llama embryos metabolically inhibited but viable at 5 °C during 24 h. Adult females (n = 20) were used as embryo donors and were superstimulated ... -
Azospirillum inoculation effects on growth, product quality and storage life of lettuce plants grown under salt stress
(Elsevier, 2015-11-12)Recent results have shown that Azospirillum-inoculated lettuce seeds yield a higher number of transplanted plants with superior traits than non-inoculated controls grown with and without saline stress. However, little ... -
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 ... -
Guanaco abundance and monitoring in Southern Patagonia: distance sampling reveals substantially greater numbers than previously reported
(Springer, 2015-12)Background: Guanacos (Lama guanicoe) are thought to have declined in Patagonia mainly as a result of hunting and sheep ranching. Currently accepted estimates of total population size are extrapolated from densities obtained ... -
Evaluation and comparison of serological methods for the detection of bovine neosporosis in Argentina = Evaluación y comparación de pruebas serológicas para la detección de la neosporosis bovina en Argentina
(Asociación Argentina de Microbiología, 2015-12)Neospora caninum is a protozoan parasite that causes abortion and important economic losses in cattle worldwide. The accurate diagnosis of neosporosis is essential for management and control measures. The aims of this study ... -
Ecosystem services research in contrasting socio-ecological contexts of Argentina: critical assessment and future directions
(Elsevier, 2015-12)In Argentina, agricultural expansion and intensification has stimulated the utilization of the ecosystem services (ES) approach to understand the consequences of land-use and land-cover changes. However, Argentina's ... -
Critical nitrogen dilution curve in processing potato cultivars
(Scientific Research, 2015-12)The critical nitrogen dilution curve (CNDC) can be used as a diagnostic tool to assess crop N nutrition during the growing season. Potato cultivars have different biomass production and accumulation of N and consequently ... -
Occurrence of glyphosate and AMPA in an agricultural watershed from the southeastern region of Argentina
