Yearly follow-up of methane turbulent exchange over an intensively grazed pasture in Belgium.
Methane emissions account for 8 % of the EU-15 GHG emissions and livestock generates 40 % of these emissions (European Commission, 2009). These fluxes are mainly measured in metabolic chambers with the drawback of bringing the cattle in an unfamiliar environment. Recent technological advances in spectroscopy now permit methane flux measurement using eddy covariance. This micrometeorological met...
متن کاملWater quality implications of nitrate leaching from intensively grazed pasture swards in the northeast US
High density animal production systems, such as management intensive grazing (MIG), can have a negative effect on water quality. Learning to manage such systems to minimize water quality impacts is essential for the environmental and economic sustainability of these types of animal production systems. Management intensive grazing is a grazing system in which animals at a high stocking density a...
متن کاملPrevalence of and Risk-Factors for Intramammary Infection in Pasture-Grazed Dairy Heifers in Late Gestation
Mastitis is a common infectious disease in dairy cattle, and is among the most economically damaging animal health problem producers face. Mastitis in dairy heifers is recognised as a distinct problem from that in older cows because of the different pattern of disease (Barkema, Schukken et al. 999; Valde, Lawson et al. 004) and unique factors that determine its occurrence (Waage, Sviland et al....

متن کاملPostgraze assessment of toxicosis symptoms for steers grazed on toxic endophyte-infected tall fescue pasture.
A 2-yr pen experiment was conducted using 12 different crossbred Angus steers each year to determine if short-term changes in prolactin concentrations, body temperature, and vasoconstriction reflect recovery from fescue toxicosis after steers that previously grazed toxic endophyte (Neotyphodium coenophialum)-infected Kentucky 31 tall fescue [Lolium arundinaceum (Schreb.) Darbysh] are placed on ...
