One of the major bottlenecks in meeting the increasing demand for livestock products is in reconciling feed production, required in ever-increasing amounts, with good management of natural resources and protection of the environment The process at all stages has a major impact on several factors...

We used an established, process-based model of the dynamics of carbon (C) and nitrogen (N) cycling between plants, soils and animals in grazed temperate pastures to clarify expectations of how some major components of intensification affect the outcomes (short-term and long-term) of alternative...

Increasing the efficiency of conversion of feed nitrogen (N) into milk and meat N in dairy cattle is an integral part of the effort to maintain or increase food production while decreasing agriculture's environmental impact. Mathematical models provide a means to assess and compare different...

According to the Intergovernmental Panel on Climate Change (IPCC), agriculture is responsible for 10-12% of total global anthropogenic emissions and almost a quarter of the continuing increase of greenhouse gas (GHG) emissions. Not all forms of agriculture, however, have equivalent impacts on...
