Heifer management characterization in dairy herds from the west of Buenos Aires, Argentina = Caracterização da gestão de novilhas em rebanhos leiteiros do oeste de Buenos Aires, Argentina
(School of Veterinary Medicine and Animal Science, University of São Paulo, 2021-09)The replacement program in a dairy farm represents the second or third largest cost in a dairy operation. This study aimed to characterize and typify the practices related to the dairy heifer replacement program and describe ... -
El nivel de engrasamiento inicial y la ganancia de peso durante la recría a corral afectan los resultados físicos y económicos del proceso de invernada
(Asociación Argentina de Producción Animal, 2010)La recría de terneros a corral es una estrategia que se ha incorporado a los sistemas de producción en los últimos seis o siete años. El manejo durante la fase de recría a corral puede afectar el resultado físico de todo ... -
Combined use of monensin and virginiamycin to improve rumen and liver health and performance of feedlot-finished steers
(American Society of Animal Science, 2022-12)Monensin and virginiamycin are included in beef cattle finishing diets as prophylaxis to minimize the incidence of ruminal acidosis and liver abscesses. Due to different and probably complementary modes of action, this ... -
Effect of cover crops on hysteresis and anisotropy of soil hydraulic properties
(Elsevier, 2022-12)No till is the main management system for soil conservation world-wide. In Argentina is frequently implemented in simplified crop sequences, which has negative effects on soil physical quality (SPQ). Among the suggested ... -
Condiciones de alojamiento de los terneros en crianzas artificiales de tambo y su relación con el estrés por frío
(Facultad de Ciencias Veterinarias, Universidad Nacional del Litoral, 2022-07)El estrés por frío en los terneros puede ser muy perjudicial para su salud y rendimiento futuro. El objetivo del presente trabajo fue evaluar el efecto de las condiciones de manejo de la crianza artificial y su relación ... -
Dietary inclusion of ruminally protected linseed oil as a means to mitigate heat and slaughter-induced stress in feedlot cattle
(Oxford University Press, 2022-03-03)There is evidence of a relationship between increased energy intake and the development of metabolic inflammation and insulin resistance (IR), and between the aforementioned metabolic state and impaired tolerance to heat ... -
Cover crops effects on soil hydraulic properties in two contrasting Mollisols of Argentinean Pampas region
(Wiley, 2022-02)Decreasing of physical quality of Mollisols in the Argentinean Pampas region is observed due to simplified crop rotations. The main objective of this work was to evaluate the effects of cover cropping management on soil ... -
Impacts of vegetative and reproductive plasticity associated with tillering in maize crops in low-yielding environments: a physiological framework
(Elsevier, 2021-05)Selection for maize (Zea mays L.) grain yield in high-yielding environments at high population densities has favored a compact phenotype tolerant to crowding stress, bearing a single, well-grained ear. However, by contributing ... -
Áreas homogéneas de producción agrícola en el este de la provincia de La Pampa
(Facultad de Agronomía, Universidad Nacional de La Pampa, 1999)El objetivo de este trabajo fue delimitar áreas con comportamientos homogéneos en la producción agrícola del este de la provincia de La Pampa (Argentina). Para ello se aplicaron técnicas de análisis multivariado (análisis ... -
Areas homogéneas de producción agrícola en la provincia de Buenos Aires, Argentina
(Facultad de Ciencias Agrarias y Forestales, Universidad Nacional de La Plata, 1996)Al considerarse los registros históricos de rendimientos de granos de girasol, maíz, trigo y soja, durante el período 1970-1993, se delimitaron 22 áreas homogéneas de producción agrícola en la provincia de Buenos Aires. ... -
Leaf protein allocation across the canopy and during senescence in earlier and later senescing maize hybrids, and implications for the use of chlorophyll as a proxy of leaf N
(Springer, 2019-09)Leaf chlorophyll (chl) and protein distribution were analyzed throughout grain filling in four modern maize hybrids with contrasting senescence behavior, at three different canopy levels and at low-N (LN, 18 kg N ha−1) and ... -
Effect of slow-release urea inclusion in diets containing modified corn distillers grains on total tract digestibility and ruminal fermentation in feedlot cattle
(American Society of Animal Science, 2015-08)Ruminal degradable intake protein (DIP) deficit may result when cattle are fed diets containing a greater inclusion of processed corn grain and small to moderate inclusion of corn distillers grains (DG). This deficit may ... -
Effect of urea inclusion in diets containing corn dried distillers grains on feedlot cattle performance, carcass characteristics, ruminal fermentation, total tract digestibility, and purine derivatives-to-creatinine index
(American Society of Animal Science, 2015-01)Increased availability of rapidly fermentable carbohydrates and a great proportion of corn-derived CP in the diet may result in a degradable intake protein (DIP) deficit. Therefore, ruminal DIP deficit may result from high ... -

(2018-10-19)El objetivo del trabajo fue conocer la producción estacional de forraje de variedades de Lolium multiflorum Lam (raigrás anual) en distintas localidades de Argentina -
Incidencias en Trichostrongylídeos en relación con los patrones de remolinos frontales en bovinos
(Facultad de Ciencias Veterinarias, Universidad de Buenos Aires, 2018)La transmisión de los nematodes gastrointestinales trichostrongylideos de los rumiantes en pastoreo está asociada con la ingestión de sus larvas infectivas distribuidas en las pasturas. Con el objetivo de analizar si la ... -
Biomass Decomposition and Phosphorus Release from Residues of Cover Crops under No-Tillage
(2017-01)Under no-tillage field conditions, cover crop (CC) residues remain on the soil surface and decompose at a slow rate. We used three CC species (oat, Avena sativa L.; rye, Secale cereale L.; and ryegrass, Lolium multiflorum ... -
Cover crop effects on soybean residue decomposition and P release in no-tillage systems of Argentina
(2014-11)Cover crops (CC) provide many benefits to soils but their effect on decomposition of previous crop residues and release of nutrients in continuous no-tillage soybean [Glycine max (L.) Merr.] production are little known. ... -
