Greenfeed animal respiration system
WebApr 1, 2024 · The GreenFeed emission monitoring system (GEM) is based on spot sampling of eructated and exhaled gases allowing measurement of enteric CH 4 production on a large number of animals in farm conditions. The system can be programmed to deliver small amounts of pelleted feeds to attract individual animals to visit multiple times per … 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.
