Abstract.
Enteric methane (CH4) emissions are directly related to the quantity and type of feed intake. Existing mitigation strategies, for example, the addition of legumes to grass-based diets and increased use of grains, have been thoroughly researched and applied in different production systems. In this paper, we propose a need to expand the capacity to mitigate enteric CH4 emissions in cattle under grazing conditions. The objective of this paper was to contribute to evaluate a mitigation strategy under grazing conditions of using contrasting levels of pasture quality. The study was performed with 20 heifers twice during the year: winter and spring. Each season, the study employed a crossover design with two treatments and two 5-day measurement periods. The treatments were two pastures with different nutritional values, including a pasture with a low quality (70% of neutral detergent fibre, 1% of ether extract, 8% of non-fibre carbohydrates), 9% of crude protein, 35% of dry matter digestibility and a pasture with a high quality (42% neutral detergent fibre, 1.3% ether extract, 24% non-fibre carbohydrates, 21% crude protein and 63% dry matter digestibility). Enteric CH4 emissions were measured with sulfur hexafluoride tracer technique. The dry matter intake (kg/day) was measured indirectly using titanium dioxide as an external marker. CH4 emissions from animals grazing the high-quality pasture were 14% lower expressed as % of gross energy intake, and 11% lower expressed by unit of dry matter intake (g CH4/kg). These results quantitative showed the alternative to mitigate CH4 emissions from grazing bovines exclusively through the improvement of the forage quality offered.

ABSTRACT: The expansion and intensification of agriculture frequently affect riparian zones, mainly in basins where agriculture is the most important activity. In countries with basins dominated by agricultural activities, land use change in riparian zones promotes water quality loss and biodiversity degradation. As a tool to prevent these environmental impacts, the delimitation of riparian zones and buffer strips is crucial. For that purpose, photo interpretation jobs and botanical studies are usually necessary. However, a digital terrain model (DTM) becomes the best alternative when the information is unavailable or the survey area is too large. This work made the first delimitation of riparian zones of the country?s water drainage network. The results obtained by using a 1-m vertical buffer in DTM allowed the delimitation of the riparian zones of Uruguay. The results indicate that of the areas identified as riparian, 62% would be authentic and that the 29% of riparian areas identified under cultivation could rise to 46% if the identification improved the identification accuracy. The results indicate the existence of 4,608,890 ha of riparian zones, of which 94,651 ha could be under cultivation. |
