Scientists are also testing a commercial system, "GreenFeed," which measures an animal's carbon dioxide, methane emission, and oxygen consumption, Gunter says.
Methane emissions from cattle: estimates from short-term measurements using a GreenFeed system compared with measurements obtained using respiration chambers or sulphur hexafluoride tracer.
Bobcat has very short awnlettes which may make it more suitable for greenfeed production.
But, as the English know, it only takes a small patch of soil to raise enough greenfeed to keep the horse satisfied.
(1999) found that for barley, yields and protein content of greenfeed for ensiling responded positively to N fertilization.
