Greenfeed animal respiration system

WebThe GreenFeed automated emissions monitoring (GF) system can be used to estimate CH4 emissions (g/d) from individual animals and has been available since about 2010 (Garnett 2012). WebMethane emission was monitored for 151 cows using the GreenFeed system. Prediction models were developed for daily and average (for the trial period of 12 or 14 days) methane production (g/d), yield (g/kg DM intake (DMI)) and intensity (g/kg of fat- and protein-corrected milk) using partial least squares regression.

WebA GreenFeed™ unit uses similar principles to a respiration chamber. However, animals can move freely in and out of the unit and gases are measured only when the animal visits. A small quantity of feed attracts the animal to place its head inside a semi-enclosed box, where air is drawn past the animal’s nose.
