Evaluación del valor nutritivo y los costos de producción del heno en pie y del ensilaje de sorgos nervadura marrón o BMR (Brown Middle Rib)
(Instituto de Ciencia Animal, Cuba, 2013)Para evaluar si la calidad y los costos de producción (CP) del ensilaje de sorgo nervadura marrón o BMR (Brown Middle Rib) son superiores a los de este cultivo diferido (heno en pie), se diseñaron dos ensayos. Uno, con ... -
Evolution of the Puccinia coronata population in Argentina and identification of resistance genes useful in oat breeding programs
(Springer, 2023-10)Crown rust caused by Puccinia coronata f. sp. avenae (Pc), is the most widespread and damaging disease in oat worldwide, causing significant losses in grain yield and quality. This research documents the evolution of the ... -
Feeding value of whole raw soya beans as a protein supplement for beef cattle consuming low‐quality forages
(2018-02)Experiments (Exp) I and II were conducted to compare raw whole soya beans (WSB), roasted (rWSB) or other protein sources as supplements of low‐quality forages fed ad libitum to beef cattle, upon DM intake (DMI), ruminal ... -
Finalización de novillos Abeerden Angus con cereales forrajeros de invierno y con grano de cereal en bajas proporciones
(Instituto de Ciencia Animal, Cuba, 2011)La finalización de novillos pesados (> 450 kg cabeza-1) se realiza normalmente en corral, debido a las altas exigencias energéticas. Sin embargo, por los costos elevados de producción (CP) los ranchos o fincas medianos y ... -
A flexible and practical approach for real-time weed emergence prediction based on Artificial Neural Networks
(2018-06)Most popular emergence prediction models require species-specific population-based parameters to modulate thermal/hydrothermal accumulation. Such parameters are frequently unknown and difficult to estimate. Moreover, such ... -
Gas production kinetics and in vitro degradability of tannin-containing legumes, alfalfa and their mixtures
(Elsevier, 2019-06)The aim of this study was to determine in vitro ruminal degradability and gas production kinetics of sainfoin (Onobrichis viciifolia; SF), birdsfoot trefoil (Lotus corniculatus; BFT), alfalfa (Medicago sativa L.; ALF) and ... -
Germinación de dos especies de Rhynchosia (Fabaceae) nativas de Argentina central útiles para la restauración productiva de pastizales naturales
(Ediciones INTA, 2021-04)Los pastizales naturales del sudoeste de la provincia de Buenos Aires (Argentina) están degradados como resultado del sobrepastoreo y de la expansión de la agricultura, que han generado un fuerte impacto en la biodiversidad ... -
Grazing diverse combinations of tanniferous and nontanniferous legumes: implications for foraging behavior, performance, and hair cortisol in beef cattle
(American Society of Animal Science, 2021-10-17)A diversity of forages with different types and concentrations of nutrients and plant secondary compounds may lead to complementary relationships that enhance cattle performance and welfare. We determined whether grazing ... -
How leaf rust disease and its control with fungicides affect dough properties, gluten quality and loaf volume under different N rates in wheat
(2018-03)The unique viscoelastic properties of gluten make bread wheat (Triticum aestivum L.) a staple food. The specific balance between gluten fractions, together with grain protein content (GPC), defines nutritional and end-use ... -
Increased Nitrogen Retention and Reduced Methane Emissions of Beef Cattle Grazing Legume vs. Grass Irrigated Pastures in the Mountain West USA
(MDPI, 2022-01)Grazing studies were carried out over a 5-year period using pregnant cows, yearling calves and 2-year-old heifers to investigate the influence of diet on intake, methane (CH4) emissions and retention of nitrogen (N). ... -
Influence of Soil Water Status on Arbuscular Mycorrhizas in Three Perennial Grasses in Central Argentina
(Finnish Zoological and Botanical Publishing Board, 2008-12)In this field study, we determined the effects of water stress, rainfed or irrigated conditions on the arbuscular mycorrhizal fungal (AMF) root colonization in the late-seral Stipa clarazii, the earlier-seral S. tenuis and ... -
Modelación productiva, económica y emisión de metano en sistemas de cría vacuna de Bahía Blanca y Coronel Rosales
(2018-08)El objetivo de este estudio de simulación fue evaluar la respuesta productiva, económica, emisión de metano y el valor marginal del agregado de alimento extra (VMA) en diferentes sistemas la cría vacuna de Bahía Blanca y ... -
Modeling Avena fatua seedling emergence dynamics: an artificial neural network approach
(Elsevier, 2012-10)Avena fatua is an invasive weed of the semiarid region of Argentina. Seedling emergence patterns are very irregular along the season showing a great year-to-year variability mainly due to a highly unpredictable precipitation ... -
Modeling seed dormancy release and germination for predicting Avena fatua L. field emergence: A genetic algorithm approach
(2014-01-24)Avena fatua is a cosmopolite weed species which produces severe yield losses in small-grain production systems in temperate and semiarid climates. In the semiarid region of Argentina, A. fatua field emergence patterns show ... -
Natural Contamination with Mycotoxins Produced by Fusarium graminearum and Fusarium poae in Malting Barley in Argentina
(2018)Two of the most common species of toxin-producing Fusarium contaminating small cereal grains are Fusarium graminearum and F. poae; with both elaborating diverse toxins, especially deoxynivalenol (DON) and nivalenol (NIV), ... -
Natural occurrence of Alternaria mycotoxins in malting barley grains in the main producing region of Argentina
