El objetivo general de este estudio es cuantificar el efecto de distintos niveles de FDN de dietas forrajeras, sobre las emisiones de CH4 entérico de novillos en terminación. Para lograr este objetivo se plantearon los siguientes objetivos específicos:i. Identificar el efecto de distinta calidad de dieta sobre el consumo y la ganancia de peso diario; y ii. Cuantificar las emisiones de CH4 según el contenido de FDN dela dieta suministrada.
ABSTRACT. The SMARTER (SMAll RuminanT breeding for Efficiency and Resilience) H2020 project aims to develop and implement innovative strategies to improve resilience and efficiency (RandE) related traits in sheep and goats. Regarding feed efficiency, the objective is to identify novel traits that would be relevant, easy to measure and cheap enough to be collected in many animals to identify the most efficient individuals. In practice, feed efficiency can be assessed by different criteria such as residual feed intake and feed conversion ratio.
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.
