A Neospora caninum vaccine using recombinant proteins fails to prevent foetal infection in pregnant cattle after experimental intravenous challenge
(Elsevier, 2014-12-15)The aim of the present study was to evaluate the immunogenicity and protective efficacy of rNcSAG1, rNcHSP20 and rNcGRA7 recombinant proteins formulated with immune stimulating complexes (ISCOMs) in pregnant heifers against ... -
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 = ... -
Age at first gestation in bovine influences female progeny post-weaning growth and reproductive development
(Elsevier, 2024-12)This study investigated the impact of the age at which heifers conceive for the first time on the growth and reproductive development of their female offspring. A total of seven heifers pregnant at 15 months of age (15M), ... -
Characterization of Immune Cell Infiltration in the Placentome of Water Buffaloes (Bubalus bubalis) Infected with Neospora caninum During Pregnancy
(Elsevier, 2014-05)Neospora caninum infection in cattle stimulates host immune responses, which may be responsible for placental damage leading to abortion. Susceptibility of water buffaloes (Bubalus bubalis) to neosporosis is not well ... -
Cytokine expression in the placenta of pregnant cattle after inoculation with Neospora caninum
(Elsevier, 2014-09-15)Neospora caninum is recognized as a major cause of reproductive losses worldwide but its pathogenesis is not completely understood. Immune mediated placental pathology has been reported as being responsible for compromising ... -
Ecografía reproductiva en ovinos: una herramienta simple y con muchas ventajas
(Estación Experimental Agropecuaria Balcarce, INTA, 2023-08)La ecografía reproductiva en ovinos es una herramienta diagnóstica de gestación que brinda multiplicidad de información para la toma de decisiones en el manejo de la majada. -
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 ... -
Efectos de la inyección de cobre en vacas Angus al final de la gestación sobre el crecimiento fetal y posnatal de sus crías
(Ediciones INTA, 2021-12)Para determinar si la inyección de Cu durante el último tercio de gestación puede afectar el crecimiento fetal y posnatal de la progenie, se utilizaron 70 vacas Angus con 219 ± 15 días de gestación y se asignaron al azar ... -
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. ... -
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 ... -
High rate of transplacental infection and transmission of Neospora caninum following experimental challenge of cattle at day 210 of gestation
(BMC, 2012-12)In order to investigate the pathogenesis of neosporosis following a primary infection in late pregnancy, cattle were subcutaneously challenged with 5 × 108 Neospora caninum (NC1 isolate) tachyzoites at day 210 of gestation ... -
Immunization with inactivated antigens of Neospora caninum induces tolllike receptors 3, 7, 8 and 9 in maternal-fetal interface of infected pregnant heifers
(2017)Neospora caninum is an obligate parasite and a major cause of abortion in cattle. Pregnancy failures appear to be associated with weak innate defences on the maternal-fetal interface during infection with N. caninum. Herein, ... -
Immunopathogenesis of bovine neosporosis throughout gestation
(College of Medicine and Veterinary Medicine, University of Edinburgh, 2013)Despite Neospora caninum being recognised as a major cause of bovine abortion, its pathogenesis is only partially understood. Evidence of immune mediated placental pathology has been reported as being responsible for ... -
Inflammatory infiltration into placentas of Neospora caninum challenged cattle correlates with clinical outcome of pregnancy
(BMC, 2014-01)Infection with Neospora caninum stimulates host cell-mediated immune responses, which may be responsible for placental damage leading to bovine abortion. The aim of this study was to compare immune responses in the bovine ... -
Late-gestation protein restriction negatively impacts muscle growth and glucose regulation in steer progeny
(Elsevier, 2019)The objective of this study was to determine whether the amount of protein provided to cows during late gestation would affect postnatal growth and lead to changes in glucose and insulin concentrations. At 129 d of gestation, ... -
