Impacto de la intensidad de laboreo en los rendimientos de arroz de la UPAG, durante tres zafras (2006/07, 2007/08 y 2008/2009).
Positive consequences of maternal diet and post-natal rumen inoculation on rumen function and animal performance of Merino lambs.
Neonatal modification of the microbial inoculum entering the gastrointestinal tract mayalter the rumen microbiome and consequently alter pre- and post-weaning rumen fer-mentation and growth of lambs.
Advances in the knowledge of Eucalyptus gall insects in Uruguay: current status and future prospects.
Uruguay has 1 million ha forested with exotic species, and 75% of this area is in Eucalyptus plantations. A national silvicultural practice characterized by large-scale plantations with monocultural stands makes it mandatory to carry out phytosanitary surveillance to prevent the entrance of new pests. A signifi cant increase in insect invasions on Eucalyptus production areas has been observed in recent years. Gall-forming insects cause concern because of the risk they pose to young plantations.

Escarabajos de corteza de pino en Uruguay:situación y perspectivas.
La actividad forestal en nuestro país ha crecido considerablemente en los últimos años hasta alcanzar un estimado de 700.000 hectáreas de eucaliptos y 300.000 hectáreas de pinos. Uno de los principales problemas sanitarios que enfrenta el sector pinero es la presencia en el país de escarabajos barrenadores de corteza (Coleoptera:Scolytinae) introducidos de Europa y Asia.

Programming rumen bacterial communities in newborn Merino lambs.
Establishment of the rumen microbiome can be affected by both early-life dietary measuresand rumen microbial inoculation. This study used a 2 × 3 factorial design to evaluate theeffects of inclusion of dietary fat type and the effects of rumen inoculum from differentsources on ruminal bacterial communities present in early stages of the lambs? life. Twodifferent diets were fed ad libitum to 36 pregnant ewes (and their lambs) from 1 month pre-lambing until weaning.
Production attributes of Merino sheep genetically divergent for wool growth are reflected in differing rumen microbiotas.
Divergent genetic selection for wool growth as a single trait has led to major changes in sheep physiology and metabolism, including variations in rumen microbial protein production and uptake of ?-amino nitrogen in portal blood. This study was conducted to determine if sheep with different genetic merit for wool growth exhibit distinct rumen bacterial diversity. Eighteen Merino wethers were separated into groups of contrasting genetic merit for clean fleece weight (CFW; low:WG?
