Nutrient Composition, Forage Parameters, and Antioxidant Capacity of Alfalfa (Medicago sativa, L.) in Response to Saline Irrigation Water
(2015-07)Although alfalfa is moderately tolerant of salinity, the effects of salinity on nutrient composition and forage parameters are poorly understood. In addition, there are no data on the effect of salinity on the antioxidant ... -
Evaluation of alfalfa (Medicago sativa L.) populations’ response to salinity stress
(2017-02)Alfalfa (Medicago sativa L.) is a moderately salt-tolerant crop with high economic return and is therefore more suitable for production with lower quality water than most high-value crops. This study was conducted to examine ... -
Variable salinity responses of 12 alfalfa genotypes and comparative expression analyses of salt-response genes
(2017-02)Twelve alfalfa genotypes that were selected for biomass under salinity, differences in Na and Cl concentrations in shoots and K/Na ratio were evaluated in this long-term salinity experiment. The selected plants were cloned ... -
High-sulfate water consumption determines intake and metabolic responses to protein supplementation in lambs consuming low-quality forage
(2017-05)Twenty Hampshire lambs (31 ± 4 kg BW) in individual metabolism cages were used in a 10-treatment by 2-period (n = 4) trial to evaluate the interaction between protein supplementation and sulfate water on intake and metabolic ... -
Response of hardwood tree regeneration to surface fires, western Chaco region, Argentina
(2014-08-15)We assessed the response of seedlings and pole-sized individuals of Aspidosperma quebracho-blanco Schlecht., Schinopsis lorentzii (Griseb.) Engler and Ziziphus mistol Griseb. to surface fires. We assessed traits of fire ... -
To chop or not to chop? Tackling shrub encroachment by roller-chopping preserves woody plant diversity and composition in a dry subtropical forest
(2017-10-15)Shrub encroachment is a frequently observed phenomenon in the arid and semi-arid biomes. In the dry forests of the Argentine Chaco ecoregion that are affected by shrub encroachment, the growing demand for grazing areas has ... -
Quantifying yield and water productivity gaps in an irrigation district under rotational delivery schedule
(2016-01)Removal of irrigation network limitations under a rotational delivery schedule has been focused on improving infrastructures without paying sufficient attention to improving management. We developed a methodology to assess ... -
Chemical composition and in vitro ruminal degradation of hay and silage from tropical grasses
(2014)This study was conducted to evaluate the effects of preservation type on chemical composition and in vitro ruminal degradation of warm-season grasses (WSG). Treatments consisted of two factors (6 2): the first factor was ... -
Prediction of the Ym factor for livestock from on-farm accessible data
(2015-07)Methane emission factor (Ym) is directly involved to calculate the worldwide livestock methane inventories, hence it is important to refine the estimation of this parameter for different livestock production systems. The ... -
Early exposure to and subsequent beef cattle performance with saline water
(2016-03)Two experiments were conducted to evaluate the impact of early life exposure to high salt water on later cattle performance with saline water. In Exp. 1, 24 cow/calf pairs were randomly assigned to one of two treatments: ... -
Hormones and monensin use to improve pregnancy rates in grazing lactating beef cows in the semiarid region of Argentina
(2018-03)The objectives of this study were 1) to determine the effect of monensin treatment, alone or combined with a hormonal estrus synchronization treatment, on the pregnancy rate of lactating beef cows, and 2) to evaluate the ... -
Measurement of malondialdehyde as oxidative stress biomarker in goat plasma by HPLC-DAD
(2016-11)During the cattle breeding, the animals are exposed to stressful conditions (confinement, competition, extreme temperatures, pathogens); these have been associated to the increase of reactive oxygen species that attack ... -
Exploring the biological activity of condensed tannins and nutritional value of tree and shrub leaves from native species of the Argentinean Dry Chaco
(2017)BACKGROUND: Tropical tree or shrub leaves are an important source of nutrients for ruminants and a potential source of biologically active compounds that may affect ruminalmetabolism of nutrients. Therefore, eightwoody ... -
Influencia del rolado selectivo de baja intensidad (RBI) sobre las comunidades de aves de bosques del Chaco Occidental
(2015-12)El rolado selectivo de baja intensidad (RBI) es una tecnología de habilitación de sistemas silvopastoriles de bajo impacto usado en la Región Chaqueña. El RBI reduce el estrato leñoso bajo (<3 m de altura), incrementa la ... -
Rolado selectivo de baja intensidad (RBI) sobre bosque nativo en el Chaco Semiárido: influencia sobre la diversidad y la composición de un ensamble de reptiles
(2017-04)El rolado selectivo de baja de intensidad (RBI) es una tecnología para habilitar sistemas silvopastoriles de bajo impacto en el Chaco Semiárido. A diferencia de otras formas de habilitar las tierras con fines ganaderos ... -
Dinámica de la humedad de los combustibles y su relación con la ecología y manejo de fuego, region chaqueña occidental (Argentina) II: follaje y residuos de árboles y arbustos
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2014-08)El fuego es fenómeno frecuente en la región chaqueña argentina. El contenido de agua (CH, %) es un factor que define la inflamabilidad de los combustibles vegetales, y sus cambios en magnitud pueden ser usados para comprender ... -
