Notes:
The characterization of xanthophylls in egg yolks from laying hens fed turf bermudagrass (Cynodon dactylon) meal was studied. Laying hens were fed 2 wk on a milo-soybean meal diet to deplete the birds' xanthophyll stores from developing ova prior to introduction of 9% turf bermudagrass. After an additional 4 wk the various carotcnoids present in egg yolks were determined by open-column, thin-layer, and high-performance liquid chromatography. Chromatographic analyses suggest that the yolk color was due mainly to the presence of free lutein and zeaxanthin at a ratio of 4:1. Neoxanthin and violaxanthin were present in minor amounts. The presence of p-carotene was not detected.
