(Plos One, 2018-12)Tall wheatgrass [Elymus elongatus subsp. ponticus (Podp.) Melderis] is a perennial forage grass cultivated in dry, saline or alkaline environments. The morpho-physiological characteristics of four populations of tall ... -
Morpho‐physiological, biochemical and isotopic response of tall wheatgrass populations to salt stress
(Wiley, 2020-12)Tall wheatgrass [Elymus elongatus subsp. ponticus (Podp.) Melderis] is a C3 grass native from dry or saline habitats in SE Europe. The aim of this study was to better understand response mechanisms of populations from ... -
Effects of inorganic selenium injection on the performance of beef cows and their subsequent calves
(Elsevier, 2020-09)Sixty-seven pregnant Angus cows and their subsequent calves were used in a randomized design to evaluate the effect of inorganic Se injection from 80 d of gestation until weaning on cow reproductive parameters, BW and BCS ... -
Promotion of Lotus tenuis and calf early weaning as a good management practice for breeding herds in marginal soils of the Flooding Pampa (Argentina)
(Ediciones INTA, 2020-08)The promotion of forage legumes in marginal environments for agriculture constitutes a major technological challenge for livestock farming. The legume Lotus tenuis (Waldst. & Kit.) is a good example of beneficial naturalization ... -
Casos inusuales de colibacilosis septicémica en terneros neonatos de cría para carne
(Facultad de Ciencias Veterinarias, Universidad Nacional del Nordeste, 2019)La colibacilosis septicémica es causada por Escherichia coli y suele afectar a terneros de tambo. El objetivo de este trabajo fue describir casos de colibacilosis en terneros de cría para carne. Las terneras afectadas ... -
Exposure to toxic fescue during late gestation on beef cows: effects on cow performance and offspring performance from birth to weaning
(ECronicon Open Access, 2020-01-03)To examine the effects of endophyte-infected tall fescue during late gestation on maternal and offspring performance, multiparous Angus cows (n = 40) were bred via AI and allocated into grazing treatments: toxic (E+) or ... -
Evaluación de la transición agroecológica de un establecimiento ganadero a base de pastizal de la cuenca del Salado, mediante indicadores = Evaluation of the agroecological transition through indicators of a livestock establishment based on native grasslands of the Salado basin
(Facultad de Ciencias Agrarias, Universidad Nacional de Cuyo, 2019-06)Son muy escasas las experiencias documentadas de manejos agroecológicos en sistemas extensivos de zonas templadas, en particular las que contemplen la utilización de pastizales naturales. Por ello nos propusimos evaluar ... -
Short-term plant community response to grassland management intended to improve forage quality for the endangered Pampas deer
(Elsevier, 2019-08)The Pampas deer is a medium-sized neotropical cervid whose population has been affected by the advancement of the agricultural frontier, poaching and depredation by introduced species. As a consequence, the population of ... -
Hydraulic conductivity and pore connectivity. Effects of conventional and no-till systems determined using a simple laboratory device
(Elsevier, 2019-03-01)Soil hydraulic conductivity is a property that describes how easily water can move through a porous space and its determination is important because it controls many soil hydrological processes. The objectives of this work ... -
Diffusivity and sorptivity determination at different soil water contents from horizontal infiltration
(Elsevier, 2019-03-15)Determination of soil hydraulic properties under non-saturated conditions is crucial in order to describe soil water dynamics in the field. The objectives of this work were: i- to determine soil water diffusivity (D) as a ... -
