CONCLUSIONS
Sponsor Day, 15th-16th May 2014
CONCLUSIONS
# EU feed sector depends on imports of protein sources (SBM)# N surplus in the EU is a major problem due to limited arable land# Improving the efficiency of protein (N) utilisation is the only option
Improvement of AA profile with free AA (new sources)Improvement of feeding precision to match the animal’s requirements
# More precision (=less margin for error)Evaluation of nutritive value of ingredients and feedsEvaluation of animals requirements
