Educational intervention proposal for planning a new curricular design: comprehensive teaching of the causal agents of infectious diseases

Juliana CANTÓN — 2025-04-01

The teaching of contemporary veterinary medicine demands innovative curricular designs that emphasize disciplinary integration. These designs enable students to build a strong foundation for their professional performance, supported by a teaching model that extends beyond the passive transmission of information. Instead, teachers actively guide and participate in the process of knowledge construction, utilizing an integrated teaching approach and an evaluation system focused on scientific and professional competencies and skills. This work presents an opinion about curricular integration, specifically through a proposal developed by faculty in Microbiology, Virology, and Infectious Diseases, aimed at informing discussions on a new curricular design at the FCV-UNCPBA. The proposal is structured around the concept of modular teaching and promotes interdisciplinary activities across courses within the Department of Animal Health and Preventive Medicine. This work is organized into several key components: an educational conceptual framework; guiding principles for the roles of teachers, students, and the learning environment; objectives; didactic design and its placement within the curricular map; the work and evaluation methodology; as well as the mechanisms for monitoring and assessing the expected impact of the proposal.

Reference values for kidney and liver functional indicators of goats in Las Colonias Department of the province of Santa Fe, Argentina

Fabian O. AGUIRRE — 2025-04-01

The reference values of the biochemical indicators of renal and hepatic functionality were estimated in Saanen and Boer breed goats of different sexes, ages and productive statuses from livestock establishments from Las Colonias Department of the province of Santa Fe, Argentina. The estimated values showed discrepancies with respect those reported in the literature. The results obtained contribute to the knowledge of the reference values of kidney and liver functional indicators of the goat breeds in the central region of the province of Santa Fe, Argentina, providing relevant and unpublished data for the region.

Fat mobilization syndrome in beef cows due to poor adaptation to corn silage consumption

Gabriela V. SANDOVAL — 2025-04-01

An outbreak of fat mobilization syndrome in breeding cows due to lack of adaptation to confinement is described in Salta, Argentina. The incidence was 8% and the lethality was 67%. Clinical signs included depression, unsteady gait, weakness, and eventual recumbency and death. Some animals in the final stages exhibited nervous signs such as blindness and walking in circles. Necropsy revealed mild jaundice in subcutaneous tissue, vascular endothelia, and organs in general, along with marked hepatomegaly, ocher coloration, and a greasy texture to the touch. Microscopically, severe hepatic lipidosis and retention of bile pigments were observed. Additionally, elevated levels of aspartate aminotransferase (AST=489±277), alkaline phosphatase (ALP 895±207 IU/L), and urea (48±13 mmol/L) were noted. Hepatic lipidosis is a well-known condition in dairy cows but is rarely described in breeding cows.

Changes that occurred in bovine dairy farms from 2014 to 2023 in the dairy basin of the Lerma Valley, Argentina

Gabriela Marcela MARTINEZ — 2025-04-01

The purpose of this work was to understand the relevant productive changes in the dairy farms of the Lerma Valley (Salta), from the beginning of 2014 to the end of 2023. During the period 2022-2023, a cross-sectional survey was carried out in 10 dairy farms, recording infrastructure, productive, health and reproductive data that was contrasted with a previous survey carried out in 2013-2014. The results show that 50% of the dairy farms changed from a grazing-based system to totally confined systems with greater incorporation of technology. This change was accompanied by a 53.4% increase in the number of cows per dairy farm, going on average from 283.4 ± 64.1 to 418.8 ± 212.7 animals, and an average daily milk production increase from 5.818 ± 1.894 to 8.298 ± 3.524 liters per farm, and from 23.6 ± 2.8 to 25.6 ± 5.9 liters per cow. Although an increase in production was evident, fundamentally from the intensification of the systems, investment in infrastructure and technology and herd size increases, deficiencies of the reproductive and health data must be studied since their parameters as the mortality and culling rates did not change.
