Impact of dairy farms on groundwater quality in a productive basin in the northeast of the Pampean Plain, Argentina
(Elsevier, 2023-11)The Pampean Plain is a relevant world food production area where livestock and agricultural activities are developed. The northeast of this region is characterized by dairy production, where large quantities of excreta ... -
The degree of maternal nutrient restriction during late gestation influences the growth and endocrine profiles of offspring from beef cows
(CSIRO, 2021)Context: Cow–calf operations in Argentina are managed under extensive grazing condition and the quality of forages is often poor during the second half of gestation. The severity of nutrient restriction in bovine gestation, ... -
The Effects of Age at Weaning and Length of Lipid Supplementation on Growth, Metabolites, and Marbling of Young Steers
(MDPI, 2020-10)The objective of this study was to determine how weaning age, days on supplements, and lipid supplementation affected the growth and marbling deposition of steers. Steers from a single sire were early weaned (n = 24) at ... -
Enyesado de suelos sódicos: modificación de sus propiedades químicas, físicas y biológicas
(Facultad de Agronomía, Universidad Nacional de La Plata, 2021-12)Los suelos sódicos ocupan una extensa proporción de la Depresión del Salado. El sodio aumenta el pH y provoca la dispersión de las arcillas generando modificaciones en la estructura de los suelos que perjudican el crecimiento ... -
Soil water availability and water absorption by maize in sodic soils with high water table
(Elsevier, 2023-05)Context: Because of the increasing prices of commodities over the last decades, crops like maize (Zea mays L.) are being cultivated in lowland sodic soils with physical-chemical constraints, such as those having natric ... -
Comparison of the 7-day CO-Synch and 8-day estradiol-based protocols for estrus synchronization and timed artificial insemination in suckled Bos taurus cows
(Elsevier, 2023-04)Two experiments were conducted to compare, follicle diameter (FD) on Day −1, corpus luteum (CL) area on Day 7, progesterone (P4) concentration on Day 7 and 18, pregnancy per timed artificial insemination (TAI) on Day 30, ... -
Cation nutrient reserves decline markedly under intensive cropping of Pampas Mollisols
(Elsevier, 2023-04)The availability of exchangeable cationic nutrients in soils, such as calcium (Cae), magnesium (Mge), and potassium (Ke), is vital for crops growth and development. However, the concentration of these nutrients can be ... -
Cover crops effects on anisotropy of unsaturated soil hydraulic properties
(Elsevier, 2023-03)No tillage (NT) is frequently implemented in simplified agricultural systems, which has negative effects on soil physical quality. Among the suggested practices to preserve the physical fertility of soils under NT are ... -
Ecophysiological Responses of Tall Wheatgrass Germplasm to Drought and Salinity
(MDPI, 2022-06)Tall wheatgrass (Thinopyrum ponticum (Podp.) Barkworth and D.R. Dewey) is an important, highly salt-tolerant C3 forage grass. The objective of this work was to learn about the ecophysiological responses of accessions from ... -
Effect of Protein Restriction During Mid-to Late Gestation of Beef Cows on Female Offspring Fertility, Lactation Performance and Calves Development
(E-Cronicon, 2019-12)Cow calf operation in Argentina are managed under extensive grazing condition and the quality of forages is often poor during second half of gestation. Protein restriction in bovine gestation affects production traits in ... -
Age at First Gestation in Beef Heifers Affects Fetal and Postnatal Growth, Glucose Metabolism and IGF1 Concentration
(MDPI, 2021-11)This study aimed to determine the effects of age at first gestation on offspring growth performance, glucose metabolism, and IGF1 concentration. Heifers impregnated by AI from a single bull at 15 months of age (15 M, n = ... -
Effects of inorganic copper injection in beef cows at late gestation on fetal and postnatal growth, hematology and immune function of their progeny
(Elsevier, 2021-10)To determine if Cu injection during late gestation can affect fetal and postnatal growth, hematology and immune function of progeny, 70 multiparous pregnant Angus cows, at 219 ± 15 d of gestation, were ranked by BW and BCS ... -

(Ediciones INTA, 2020-12)Se realizó un estudio para evaluar el efecto de la vacunación contra el virus de la fiebre aftosa (FA), aplicada durante el periodo embrionario, sobre la pérdida de preñez en un rodeo de vacas Angus que habían sido inseminadas ... -
Persistencia de los efectos de la descompactación del suelo con paratill
(Facultad de Ciencias Agrarias y Forestales, Universidad Nacional de La Plata, 2020-07)En la Argentina predomina como sistema productivo la siembra directa donde la ausencia de remoción y el tránsito de máquinas cada vez más pesadas han incrementado los problemas de compactación. Para revertir este fenómeno ... -
