Cattle

Cattle breeding for lower greenhouse gas emissions

  • Cattle with a greater ability to convert feed into energy will eat less feed, produce less methane (greenhouse gas equivalent to 28 CO2 units) and improve feed conversion efficiency (FEC), with economic benefits to the farmer.

Managing genetic codes to reduce methane emissions from cattle

  • Although methane emissions depend partly on the quantity and quality of feed consumed, differences in individual animal characteristics produce variation in methane emissions between animals.

    Unravelling the genetics that determine animal characteristics will allow farmers to take advantage of low emissions animals.

Managing pastures to reduce methane emissions from cattle

  • Pastures that reduce methane emissions can be categorised into high quality grasses and legumes and plants containing secondary metabolites like tannins.

Reducing methane emissions from beef cattle using feed additives

  • Domesticated livestock produce significant amounts of methane as part of their normal digestive processes.

    Feed additives inhibit the micro-organisms that produce methane in the rumen and subsequently reduce methane emissions.
