Factors affecting recording methane emission phenotypes of composite and crossbreed beef cattle grazing tropical and subtropical rangelands of Northern Australia.

Abstract excerpt

Globally agricultural emissions contribute 10%-12% of all anthropogenic greenhouse gas emissions. Ruminant livestock account for a considerable proportion of these emissions, with cattle grazing in tropical and subtropical regions representing a major source. Enteric methane production has climatic implications and represents a loss of energy from the animal that could be directed toward growth. This study...
