Kemin has released ORO GLO® Dry to replace previous pigmenting additives with lower concentrations of xanthophyll. Kemin has supplied pigmenting products for the egg industry for four decades and has established technology to ensure stability and biological activity.

ORO GLO® 50 Dry provides 50 grams of xanthophyll activity per kilogram of commercial product.

The efficacy of the new preparation was confirmed in a trial conducted by the University of Illinois comparing the biological action of ORO GLO® 50 with ORO GLO® 30.  Data showed that the concentrated product provided similar pigmenting ability on a proportional dietary addition basis. Mean total xanthophyll level of 43 mg/kg egg and 12 micrograms/kg of lutein per egg were assayed irrespective of the concentration of the pigmenter.

ORO GLO® 50 increased the visual score for yolk pigmentation from a level of 7 to 9 within two weeks of initiating supplementation. Again there was no difference between supplementation with either ORO GLO® 30 and ORO GLO® 50 on a projected equal xanthophyll content of the diet.
