　　The Panel on Additives and Products or Substances used in Animal Feed （FEEDAP） evaluated （i） lutein from a saponified extract from Tagetes erecta obtained via extraction and saponification （lutein not less than 85% of total carotenoids （TC）） and （ii） lutein/zeaxanthin extract from Tagetes erecta obtained via extraction, saponification and isomerisation （lutein not less than 45% and zeaxanthin not less than 35% of TC）。 The maximum proposed use level of 80 mg TC from saponified Tagetes extract/kg complete feed for chickens for fattening and laying hens is safe for these animal categories. This conclusion can be extrapolated to minor poultry species for fattening and laying. The conclusions on saponified Tagetes extract for poultry for fattening and laying are extended to the saponified/isomerised Tagetes extract.
