Stocking management effects on forage composition, cow methane emissions, and soil properties of cool season pastures

An abstract of a study by Russell et al determining the methane emissions of cows utilizing sulfur hexafluoride is presented. Monthly forage mass and composition differed little between treatments. However, during methane emission measurements, IVDMD and CP concentrations were greater (P < 0.05)...

Description
Summary:An abstract of a study by Russell et al determining the methane emissions of cows utilizing sulfur hexafluoride is presented. Monthly forage mass and composition differed little between treatments. However, during methane emission measurements, IVDMD and CP concentrations were greater (P < 0.05) and NDF concentrations lower (P < 0.05) in live forage in the upper canopy of ROT than STP pastures in August. There were no significant treatment effects on daily methane emissions per cow. In October of yr 3, soil bulk density did not differ between treatments, but soil penetration resistance at depths of 0, 12.5, and 15.0 cm were greater (P < 0.05) in CONT than STP pastures.
