ABSTRACT.- Residual feed intake (RFI) and methane (CH4) emissions are potential new selection objectives in beef and sheep breeding programmes to assist reaching greenhouse gas mitigation targets and to support economic, social, and environmental sustainability. Phenotyping platforms in both species are in place in Uruguay, linked with the genetically evaluated populations of main breeds (Hereford, Merino, Corriedale, Dohne and Texel), being the basis of the reference populations for genomic selection. Current progress and main findings are described here.

RESUMEN:La fiebre Q es una zoonosis distribuida mundialmente, causada por Coxiella burnetii. Los bovinos, ovinos y caprinos son la fuente más frecuente de infección en humanos, en los que la enfermedad es de notificación obligatoria ante el Ministerio de Salud Pública. Revisamos las publicaciones que describen casos de fiebre Q en humanos en Uruguay, con foco en sus características epidemiológicas, y discutimos las pruebas diagnósticas disponibles localmente. Se incluyeron nueve trabajos publicados e información del registro de enfermedades profesionales.

bstract: Yellow lamb disease is an infrequent disease in sheep for which there is scant literature, and that has been reported in the US, Australia, New Zealand, South Africa and Europe, although anecdotal evidence indicates that it may have also been diagnosed in South America. The disease is produced by some strains of Clostridium perfringens type A that produce unusually high levels of alpha- toxin. Because C.

Se evaluó el efecto de dos cargas animales (C; 12 -CB- y 18 -CA- corderos/ha) y 3 tipos de suplemento (TS; sorgo -Sg-, maíz -M- y afrechillo de arroz -AA-) al 1% del peso vivo (PV) y sin suplementación -SS- sobre la productividad de corderos cruza Corriedale x Merino Dohne durante 97 días sobre una pastura mezcla de trébol rojo (TR) y achicoria (Ach).

El objetivo del presente trabajo fue evaluar la respuesta de estrés de terneros con y sin pre-acondicionamiento en etapas tempranas, al momento del destete definitivo con 6 meses de edad.

ABSTRACT. - SMARTER (SMAll RuminanT breeding for Efficiency and Resilience) is an H2020 EU multi-actor project, whose global objective is to develop novel and collaborative strategies to improve resilience and efficiency of the sheep and goat sectors at the animal, population/breed and system/farm levels. A dedicated work package (WP6) aims to contribute to accelerated genetic progress for resilience and efficiency (R&E) through international harmonisation and cooperation in order to deploy genomic evaluations across countries.

Worldwide, gastrointestinal parasites (GIP) generate numerous productive and economic losses in sheep production and Uruguay does not escape to this problem. Due to the aggravating situation of anthelmintic resistance to all drugs available in the market, the use of non-chemical alternative strategies is essential to address the problem of GIP.

Abstract:Bacterial, protozoal and viral diseases are major causes of abortion in sheep and goats. These agents cause significant economic losses, and many are considered of concern for public health (zoonotic pathogens) and/or the international trade of livestock, such as those causing diseases notifiable to the World Organization of Animal Health (OIE). In South America, information about their occurrence, prevalence and economic impact is scarce.

Este artículo sintetiza las bases y la puesta en funcionamiento de la Majada Cooperaria, como instrumento para el desarrollo del sector ovino en el marco del Proyecto Regional ANDE - MJA. La iniciativa surge como parte de un trabajo interinstitucional, con foco en la pequeña escala productiva y en la mano de obra familiar.
