3 ECO-FCE overview Feb 2013 Feb prtners Overll objectives improve food security by optimising feed efficiency (FE) in pigs without negtively impcting on niml welfre or met qulity reduce the ecologicl footprint of pig production Tegsc objective to exmine gut structure, function nd microbiot in pigs divergent for FE

4 Expected benefits Improved FE (microbiot, feed dditives & genetics) feeding costs emissions improve met qulity improve niml welfre Improved intestinl microbil profile costs ssocited with sick nimls (growth check, mediction, housing, lbour, etc.) better digestion nd nutrient uptke Implementtion of n Internet ECO-FCE hub fctors ffecting feed efficiency ecologicl clcultors

5 ECO-FCE overview RFI = Difference between observed feed intke nd tht predicted by growth (lower is better) Intestinl structure & function Genomics Genetics Low RFI Intestinl helth Helth & welfre High Animl performnce Medium Intestinl microbiot Met qulity
