10. Well known activity datas for the Austrian Inventory Animal population data (Statistik Austria - www.oestat.gv.at) Animal population data (Statistik Austria - www.oestat.gv.at) Average annual milk production of dairy cows Average annual milk production of dairy cows Animal lifeweight Animal lifeweight Climate Climate Rations of Austrian cattle are known Rations of Austrian cattle are known N excretion N excretion

11. Possibilities for future - improvement of inventory quality Milk production – differentiation between milk production from conventional and organic systems Milk production – differentiation between milk production from conventional and organic systems Ration: Organic rations for dairy cattle Rations for fattening pigs and sows Ration: Organic rations for dairy cattle Rations for fattening pigs and sows It might be useful to develop a methodology that estimates methane emissions from net energy intake It might be useful to develop a methodology that estimates methane emissions from net energy intake Update of the feed intake levels – VS excretion Update of the feed intake levels – VS excretion Bo values – IPCC default values are used Bo values – IPCC default values are used
