Ruminant husbandry is a major source of anthropogenic greenhouse gases (GHG). There is a large body of nutrition-related GHG and ammonia (NH3) mitigation data, but it is not well organised. The GLOBAL NETWORK will accumulate, analyse, and systematise these existing resources.
The objectives of Global Network are to:
The focus of the Global Network project was to develop databases aimed at prediction and mitigation of greenhouse gases (GHG), specifically enteric methane, from ruminant production systems. The databases collate individual animal data relating to dairy and beef cattle and small ruminants (sheep and goats) diets, intake, GHG emissions, and animal performance.
The dairy cattle database comprised of 5,233 individual dairy cow records from 154 published and unpublished studies conducted in 15 countries in Europe, North and South America, and Oceania. In addition to the dairy cattle data, the project databases contain over 2,000 individual animal beef data and over 2,800 individual animal small ruminants data.
The analyses developed simple and more complex enteric methane prediction equations and proposed effective and feasible mitigation practices. Data showed that some of the Ym factors (expressing enteric methane emission on a gross energy intake basis) used by the Intergovernmental Panel on Climate Change (IPCC) are inadequate and need to be updated for more accurate estimation of global and national GHG inventories.
