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 ... -
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 ... -
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, ... -
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 ... -
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 ... -
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 ... -
Efecto de la vacunación contra el virus de la fiebre aftosa sobre la pérdida de preñez en un rodeo de bovinos para carne
(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 ... -
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 ... -
Effect of protein restriction of Angus cows during late gestation: Subsequent reproductive performance and milk yield
(2018-06)The effect of level of CP fed during late gestation on reproductive performance and milk production was studied in multiparous cows. Sixty-eight pregnant Angus cows were used. At 121 d prepartum, cows were blocked by BW ... -
Effect of protein restriction of bovine dams during late gestation on offspring postnatal growth, glucose-insulin metabolism and IGF-1 concentration
(2018-06)The objective of this study was determine whether the amount of protein provided to cows during late gestation would affect postnatal growth and lead to changes on glucose, insulin and insulin-like growth factor concentrations. ... -
