Effect of breed and pasture type on methane emissions by growing beef steers

Research output: Chapter in Book/Report/Conference proceedingConference Proceeding (Non-Journal item)


Larger, faster-growing animals should partition relatively more nutrients into production, and therefore be more efficient. As a result the output of polluting excretion products on a per unit product basis would be expected to be
lower for modern cattle breeds. In contrast, native cattle breeds are generally smaller and slower-maturing, but are perceived to have been bred under conditions that ensured they were hardy and able to survive in exposed conditions on nutritionally poor vegetation. Thus it is possible that physiological or behavioural differences may result in them utilising low quality rough grazing more efficiently than modern breeds. The aim of this study was to explore the extent to which
breed might influence methane emissions from growing cattle grazing contrasting pasture types
