ABSTRACT.- Honey bees (Apis mellifera L.) construct a structured nest with separated areas for the brood, pollen and honey that optimizes the functioning of the colony. However, in the Eucalyptus grandis plantations, bees tend to store a great amount of pollen and nectar in the brood area during the flowering period, reducing the space for the queen's egg laying. Through the python informatic program "CombCount" and an image program, the capped brood area and the proportion of cells occupied by brood, pollen or nectar during the flowering period of E.

RESUMEN.- En el caso del Instituto Nacional de Investigación Agropecuaria (INIA) de Uruguay, en el marco del Plan Estratégico Institucional 2016-2020 con visión 2030, se definió como uno de los lineamientos estratégicos mejorar los indicadores de cantidad y calidad de publicaciones científicas arbitradas. El artículo que se propone presentará los resultados obtenidos del estudio, permitiendo la discusión acerca de la pertinencia estratégica, la evolución, la conformación de grupos de trabajo y las vinculaciones institucionales en relación con la publicación de artículos científicos.

Los parásitos gastrointestinales (PGI) han sido y continúan siendo una de las principales causas de pérdidas productivas y económicas en los sistemas productores de ovinos a nivel mundial. Debido a la grave situación que ha alcanzado la resistencia a los antihelmínticos, al cambio climático y cambio en los sistemas de producción, se ha vuelto muy difícil el control de H. contortus y de otros PGI. Por ello, el método Famacha© es una herramienta que amerita mayor exploración e implementación a
nivel de majadas comerciales, sobre todo en los planes integrados de control parasitario.

RESUMEN.- La realidad dinámica de los procesos de investigación y desarrollo tecnológico en el sector agropecuario nacional, generada por cambios abruptos en la demanda de alimentos y sus características, sistemas de certificaciones, irrupción de nuevas tecnologías (TICs), y cambios en el desarrollo del mercado tecnológico

ABSTRACT.- We reviewed the history, epidemiology, clinical signs, pathology, pathogenesis, treatment, control, and prophylaxis of Sorghum poisoning in livestock. Economic losses in the livestock industry associated with sorghum have been reported since the 19th century. Hyperacute/acute poisoning associated with cyanide (HCN) or nitrate/nitrite frequently occurs in ruminants that consume high quantities of growth and regrowth sorghum after drought, followed by rainfall, respectively.

ABSTRACT.- The global rise in afforestation highlights the need for improved forestry practices, underscoring the demand for enhanced management strategies and research. Integrated intercropping systems offer sustainable solutions, promoting biodiversity and ecosystem health. This research explored the long-term effects of weed control and row spacing on eucalyptus (Eucalyptus grandis) and pinus (Pinus taeda), intercropped with switchgrass (Panicum virgatum), within a Uruguayan setting.

Introduction: Flight distance (FD) is a temperament test associate to lying time of dairy cows in early lactation and under a conventional millking system. Objective: To determine the relationship between FD test of Holstein cows in late lactation and grazing behavior under conventional milking system.

ABSTRACT.- Throughout their domestication, sheep have adapted to environmental heterogeneity, from the tropics to the highlands. Climate and human selection have shaped the genome and left genetic 'fingerprints' on breeds bred in diverse regions worldwide. The small ruminants have evolved to be highly efficient and provide
a valuable model for identifying the genetic pathways and mechanisms underlying adaptation.

INTRODUCTION: In livestock, the advancement of genotyping technology has introduced new methods for assessing inbreeding based on single nucleotide polymorphism. Homozygosity runs (ROH) provide a more accurate method for estimating past and recent inbreeding rates at the individual/population level compared to traditional pedigree-based estimations or in the absence of pedigree records. Furthermore, ROH metrics can be used for the identification of regions under strong selection and
provide insights into evolutionary trends over time.
