1 Nordic Feed Evaluation System Harald Volden, TINE SA Norwegian University of Life Sciences scientific group
2 A feed evaluation system for cattle Net energy Metabolizable protein Feed intake Animal requirements and feeding standards Feed table Feed analysis and ring tests IT development
3 New feed evaluation system? Key questions: What are the driving forces? Who wants a new system? Who are the customers? Who has the financial power to develop and operate a new system in a long term perspective The Nordic dairy cattle advisory organisations
4 Changes in Nordic dairy cattle production Number of dairy farms has decreased ( ) Denmark 75% (3,800) Sweden 70% (4,000) Finland 70% (10,400) Norway 60% (10,600) Iceland 50 % (660) Swedish dairy farms Number of cows has decreased ( ) Denmark 20% (580,000) Sweden 30% (345,000) Finland 30% (280,000) Norway 30% (240,000) Iceland 15 % (26,000) A cost sharing strategy is important in development and implementation of a new feed evaluation system mill 4
