Abstract: Mixed crop?livestock long-term experiments (LTE) are critical to increase the understanding of sustainability in complex agroecosystems. One example is the ?Palo a Pique? LTE which has been running for 25 years in Uruguay (from 1995 to present), evaluating four pasture?crop rotations under livestock grazing with no-till technology in soils with severe limitations. The results demonstrate that cropping systems reduced soil organic carbon (SOC) compared with permanent pastures, and that perennial pastures rotating with crops were critical to mitigate SOC losses.

ABSTRACT. Sorghum leaves with concentric lesions, alternating purple to red and beige to cinnamon, were observed for the first time inJanuary 2017. The same symptoms were observed later in 29 % of sorghum cultivars in official Evaluación Nacional deCultivares INASE-INIA trials. The pathogen was identified as Microdochium sorghi (syn. Gloeocercospora sorghi) oncepathogenicity trials, morphological and molecular descriptions were done.

ABSTRACT. The intensification of agricultural production has become a topic of intense debate in academic andsocio-political media worldwide.

ABSTRACT. Income elasticities of demand were estimated for nine aggregate food categories for a sample of Hispanic consumers. In general, the demand for food appears to be relatively inelastic with respect to income, although the situation may be quite different when more disaggregated food categories are considered. Government subsidies received by households may also impact the demand for specific food groups.

ABSTRACT. Latin America in general and the Rio de la Plata Grasslands (RPG) in particular, are one of the regions in the world with the highest rates of change in land use/land cover (LULC) in recent times. Despite the magnitude of this change process, LULC descriptions in the RPG are far from being complete, even more those that evaluate LULC change through time. In this work we described LULC and its changes over time for the first 14 years of the 21st century and for the entire grassland biome of the Rio de la Plata, one of the most extensive grassland regions in the world.

ABSTRACT. The benefits of pasture-based systems on the fatty acid composition of sheep meat appear to be achievable despite variability in the quality of the pastures. Lambs fed high levels of temperate pastures have an excess of N-ammonia derived from protein degradation.

ABSTRACT. Here, we evaluate the ecosystem functioning and the ecosystems services supply of different vegetation types (grasslands, shrublands and woodlands) under contrasting management regimes by comparing a protected area with the surrounding landscape, which has been subjected to human disturbance in the Eastern Hills of Uruguay. We propose, based on functional attributes and vegetation physiognomy, a State and Transition Model for the dynamics of the grassland?woodland mosaic.

Abstract: Recent studies have shown that cattle practitioners are concerned about painful conditions and procedures. An understanding of the attitudes toward pain is fundamental to encourage the use of pain relief in cattle. The goal of this study was to investigate the factors that influence Brazilian professionals toward the use of pain mitigation in cattle, primarily during castration and horn removal (e.g. dehorning, disbudding). To reach this objective, an online survey was conducted with veterinarians and animal scientists.
