A Case Study Evaluating Economic Implications of Two Grazing Strategies for Cattle Ranches in Northwest Argentina
(Elsevier, 2009-09)In the Argentinean Chaco Arido region, cattle production based on cow–calf operations is the principal source of agricultural income, and rangeland is the main forage source for cattle. Traditional grazing strategy (TGS, ... -
A comparative pattern of lectin-binding in the endometrial glands of the uterus and placenta of healthy buffaloes and bovines at early gestation
(Tech Science Press, 2021)Water buffalo (Bubalus bubalis) and domestic cattle (Bos taurus) are closely related species. However, embryo transfer interspecies has been attempted without any success. The failure in hybrid embryo-implantation is ... -
A comparison of two in vitro bioassays to detect resistance of the cattle tick Rhipicephalus microplus to fipronil
(Elsevier, 2023-01)The aim of this work is to compare the sensitivity of two in vitro bioassays to detect resistant to fipronil in Argentinean populations of the cattle tick Rhipicephalus microplus. Two different larval bioassays prepared ... -
A descriptive Study of lectin histochemistry of the placenta in cattle following inoculation of Neospora caninum.
(Elsevier, 2019-01)The aim of this study was to describe the lectin-binding pattern in the placentas of cows infected experimentally with Neospora caninum. Four cows were inoculated intravenously with 1 × 108 tachyzoites of the NC-1 strain ... -
A DNA vaccine formulated with chemical adjuvant provides partial protection against bovine herpes virus infection in cattle
(2017-01-25)Bovine herpesvirus-1 (BoHV-1) is the causative agent of bovine infectious rhinotracheitis, an important disease worldwide. Although conventional BoHV-1 vaccines, including those based on the use of modified live virus and ... -
A dose-dependent response to MEK inhibition determines hypoblast fate in bovine embryos
(BioMed Central, 2019-07-04)Background: The segregation of the hypoblast and the emergence of the pluripotent epiblast mark the final stages of blastocyst formation in mammalian embryos. In bovine embryos the formation of the hypoblast has been ... -
A meta-analytical evaluation of the effects of high-salt water intake on beef cattle
(Oxford Academic Press, 2021-08)Adequate drinking water is essential to maintain acceptable production levels in beef cattle operations. In the context of global climate change, the water scarcity forecasted for the future is a growing concern and it ... -
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 ... -
A new cage-like particle adjuvant enhances protection of foot-and-mouth disease vaccine
(Frontiers Media, 2020-07)Foot-and-Mouth Disease (FMD) is an acute viral disease that causes important economy losses. Vaccines with new low-cost adjuvants that stimulate protective immune responses are needed and can be assayed in a mouse model ... -
A new method for simultaneous detection and discrimination of Bovine herpesvirus types 1 (BoHV-1) and 5 (BoHV-5) using real time PCR with high resolution melting (HRM) analysis
(Elsevier, 2016-01)Bovine herpesvirus types 1 (BoHV-1) and 5 (BoHV-5) are antigenically and genetically similar. The aim of this study was to develop a simple and reliable one-step real time PCR assay with high resolution melting (HRM) ... -
A novel association of BoLA DRB3 alleles in BLV infected cattle with different proviral loads
(2017)Bovine leukemia virus (BLV) is associated with the most common neoplastic disease of cattle. BLV has a silent dissemination in the herd due to infected cell exchange, thus the concentration of BLV-infected cells in blood ... -
A novel MHC-II targeted BVDV subunit vaccine induces a neutralizing immunological response in guinea pigs and cattle
(Wiley, 2021-11)Bovine viral diarrhoea virus (BVDV) is a major cause of economic loss in the cattle industry, worldwide. Infection results in reduced productive performance, growth retardation, reduced milk production and increased ... -
A novel pathogenic mechanism for cerebellar lesions produced by Solanum bonariense in cattle
(American Association of Veterinary Laboratory Diagnosticians, 2015-05)Intoxication with Solanum bonariense in cattle causes cerebellar cortical degeneration with perikaryal vacuolation, axonal swelling, and death primarily of Purkinje cells, with accumulation of electron-dense residual storage ... -
