(Facultad de Agronomía y Veterinaria, Universidad Nacional de Río Cuarto, 2025-07)La dermatosparaxis es un trastorno hereditario, de carácter autosómico recesivo, que se caracteriza por provocar alteraciones en el tejido conectivo de los individuos afectados. En este trabajo se describen los hallazgos ... -
Nitrate and nitrite acute poisoning in feedlot cattle caused by ingestion of Portulaca oleracea
(Springer, 2025-07-14)Nitrate and nitrite poisoning is a frequently lethal disease diagnosed in production animals due to the consumption of excessive levels in feed or water. The aim of this report was to describe an acute outbreak of nitrate ... -
Oxidative and inflammatory status, daily weight gain, intake and feed efficiency on natural congenitally Neospora caninum infected dairy calves
(Elsevier, 2025-08)This study explored the effect of Neospora caninum infection on oxidative and inflammatory status in newborn dairy calves and the relationship between antibody levels in dairy cows and congenital transmission. The study ... -
Feed additives for methane mitigation: Assessment of feed additives as a strategy to mitigate enteric methane from ruminants. Accounting; How to quantify the mitigating potential of using antimethanogenic feed additives
(Elsevier, 2025-01)Recent advances in our understanding of methanogenesis have led to the development of antimethanogenic feed additives (AMFA) that can reduce enteric methane (CH4) emissions to varying extents, via direct targeting of ... -
Varicellovirus bovinealpha (BoAHV) 1 and 5 activate distinct toll-like receptors signaling pathways in neural cells
(Elsevier, 2025-05)Varicellovirus bovinealpha (BoAHV) types 5 and 1 are closely-related, neurotropic alphaherpesviruses. BoAHV-5 is the etiological agent of non-suppurative meningoencephalitis in calves, whereas BoAHV-1 is responsible for ... -
Aislamiento de Lactobacillus reuteri de pollos con potencial efecto probiótico = Isolation of Lactobacillus reuteri from chickens with probiotic potential effect
(Sociedad de Medicina Veterinaria de la República Argentina, 2024-06)Existen numerosos microorganismos con capacidades probióticas, siendo las bacterias ácido lácticas (BAL) del género Lactobacillus las que se encuentran presentes en el tracto gastrointestinal (TGI) de los animales. Hay ... -
Optimization of bovine oocyte cryopreservation: membrane fusion competence and cell death of linoleic acid-in vitro matured oocytes subjected to vitrification
(Frontiers Media, 2025-07-03)Long-term conservation of livestock female genetic resources has led to increased interest in oocyte cryopreservation. However, the challenges of preserving large-volume cells and the lack of standardization in vitrification ... -
