ABSTRACT.- The aim was to compare the behavioral and physiological responses to tail docking with rubberrings in weaned twin lambs housed with either their docked or undocked sibling,or with familiar lambs that were docked or undocked. -- RESUMEN.- El objetivo fue comparar las respuestas comportamentales y fisiológicas al descole con anillos de goma en corderos mellizos destetados y alojados con sus hermanos descolados o no, o con corderos familiares descolados o no.

RESUMEN.- La ganadería representa una de las principales actividades económicas del Uruguay. En particular, la exportación de carne bovina es un rubro clave en la generación de divisas. El presente trabajo tuvo como objetivo determinar el contenido de vitaminas B3, B6 y B12 en tres cortes de carne cruda y cocida: Bife angosto (Longissimus lumborum), Cuadrada (Biceps femoris) y Nalga de adentro, provenientes de novillos terminados a pasto, con el fin de cuantificar su valor nutricional en condiciones de consumo habituales.

Agricultural intensification and changes in land use have led to a significant increase in the areas dedicated to monoculture plantations. Consequently, the diversity of polliniferous and nectariferous resources available for honey bees has decreased.

Latin America is a wide region with diverse geography and climates that exhibits a vast biological diversity, and is characterized by being a food-producing region. This review highlights the necessity to support countries with limited information regarding honey bee pathogens, to develop consensus protocols of monitoring, and to define mitigation methods at a regional scale.

The objective of this study was to analyze the association between the infection levels of V. destructor pretreatment with the adult and brood population and the colony losses in later times.

INTRODUCTION.- This work addresses the sustainable intensification of production systems through the analysis of four systems that combine agriculture and livestock with varying levels of soil use intensification. We evaluated their economic outcomes, environmental impact (i.e., emission profiles, contribution of each process, and partial carbon footprint), and contributions to food security using data from a long-term experiment.

Uruguay is a territorially small country but with a beekeeping sector economically and socially relevant. The varroosis was the disease with greater economic damage for the chain. These results are a first snapshot of the quantification of the economic cost of bee health and should be considered in the design of politics for improve the sustainability of the beekeeping sector.

Latin America (LA) is a major producer and exporter of animal and plant-based food products, of which plant product yields rely heavily on entomophilous pollination; with bees being the major pollinators. We aim to promote the integration of apiculture and meliponiculture into diversified agricultural systems, aided by knowledge-based actions, to produce quality foods for our populations; taking into account environmental conservation, the local cultural heritage, and the rational use of our natural resources.

Rice blast, caused by Pyricularia oryzae, is one of the most destructive diseases of rice in the world. In Uruguay, approximately 35% of the rice area was cultivated with susceptible cultivars in 2022-2023. The blast fungus shows a high degree of variability in the field, and limited information is available on its genetic diversity and population structure in Uruguay. Knowing the genetic variability of this pathogen will provide information useful for genetic improvement programs.

The present study aimed to determine the content of the bioactive compounds: anserine, carnosine, L-carnitine, coenzyme Q10, glutathione, and taurine in raw and cooked beef aged for 5 or 90 days.
