El Sistema Forestal de INIA se encuentra iniciando un nuevo proyecto de investigación enfocado a la sanidad forestal en el que se abordan tres problemas sanitarios, priorizados por el sector privado o identificados como relevantes a partir de su prevalencia a nivel de campo. El siguiente artículo presenta los objetivos, equipos e instituciones colaboradoras para el abordaje de cada uno de los componentes del proyecto.

ABSTRACT.- The increasing global demand for food and the strong effect of climate change have forced animal science to advance regarding new methods of selection in search of more efficient animals in production systems. Feed consumption represents more than 70% of the costs of sheep farms, and more efficient animals can increase the farmers? profitability. One of the main measures of feed efficiency is estimated residual feed intake (RFI), created in 1963 by Robert Koch for estimation in cattle and later adapted for sheep.

ABSTRACT.- Livestock production in southern South America heavily relies on extensive native grasslands, characterized by high plant species diversity, which makes estimating forage digestibility and intake by ruminants in this pastoral ecosystem challenging. Therefore, the aim of this study was to generate regression models to establish the relationship between total faecal nitrogen excretion (FNe) and intake, and faecal nitrogen content (FNc) and digestibility in sheep fed multispecies native forage.

ABSTRACT.- Canine tick-borne diseases, such as babesiosis, rangeliosis, hepatozoonosis, anaplasmosis and ehrlichiosis, are of veterinarian relevance, causing mild or severe clinical cases that can lead to the death of the dog. The aim of this study was detecting tick-borne protozoan and rickettsial infections in dogs with anemia and/or thrombocytopenia in Uruguay. A total of 803 domestic dogs were evaluated, and 10% were found positive (detected by PCR) at least for one hemoparasite.
