A team involving Chilean and UK based researchers tested the effects of including different fat sources in dairy cow diets in the form of unprocessed oilseeds including rapeseed, linseed and cottonseed simultaneously on methane emissions, nitrogen utilization...
Combing a cow’s own genetics with strategies that target changes in her rumen flora may be able to reduce methane emissions more effectively than by only selecting for low methane-emitting cows, according to a study from Denmark.
Dietary approaches from ration balancing to plant extract supplementation could boost milk yields in developing countries while supporting a reduction in methane emissions, said a leading Indian researcher.
Feeding trials are demonstrating that a pellet developed from grape marc and lucerne ‘offal’ by researchers at the University of Adelaide in Australia, could be an economically viable route to reducing methane emissions in ruminants.
Nutrition and feeding approaches may be able to lower enteric methane in dairy production by up to 15%, but rumen modifiers have had very little success in terms of sustained methane reductions without compromising milk production, found a meta-analysis.
