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.

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.

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.

¿Qué es lo nuevo sobre el control de esta enfermedad?. En los últimos años se ha venido desarrollando un paquete tecnológico integral para el control de la Leucosis
Enzoótica Bovina (LEB) en tambos de Uruguay, una herramienta hasta ahora inexistente en el país. Este es un desarrollo conjunto entre la Plataforma de
Investigación en Salud Animal de INIA, el IPMon y la empresa ATGen.

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.

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.

ABSTRACT.- Pregnancy rates following embryo transfer (ET) in cattle may be influenced by transient inflammatory responses triggered during the procedure. The objective of this study was to evaluate the effect of tolfenamic acid (TA), a nonsteroidal anti-inflammatory drug (NSAID), on pregnancy rates in embryo-recipient females. A total of 1431 recipients (367 heifers and 1064 cows) were enrolled in 34 ET programs conducted on 24 commercial farms in Uruguay, using either in vivo-derived or in vitro-produced embryos, fresh or frozen.
