“…Kuzmicky et al (486) compared pure neoxanthin and violaxanthin with pure lutein as skin pigmen ters; all were derived from extraction of fresh alfalfa. On the basis of toe-web analysis and visual scoring, neoxanthin had about 8% of the pigmenting potency of lutein, and violaxanthin was essentially ineffective.…”

“…procedure of Quackenbush et al (1970). The NEX procedure essentially eliminates the epoxide xanthophylls, neoxanthin and violaxanthin, which have very little or no pigmentation potency CMarusich et al, I960; Kuzmicky et al, 1969).…”

The availability of the xanthophyll of alfalfa leaf protein concentrate (Pro-Xan) was evaluated in two trials with broilers and one trial with laying hens. In the broiler trials, freezedried Pro-Xan and Pro-Xan dried in a pilot plant Heil dehydrator at outlet temperatures of 76.7 and 90.6°C. were shown to have xanthophyll availabilities of about 1.7 times that of dehydrated alfalfa and three times that of marigold meal. The xanthophyll availability of dehydrated alfalfa was about half that of pure lutein and twice that of marigold meal. Similar results for xanthophyll availability were found for freeze-dried Pro-Xan, dehydrated alfalfa, and lutein in the laying hen trial.

“…Similarly, violaxanthin from dehydrated alfalfa meal was not recovered from egg yolks (Nakaue et al, 1966). Kuzmicky et al (1969) found neoxanthin to be only 8% as effective in pigmenting broiler skin as lutein whUe violaxanthin was basically ineffective. Despite this low utilization of the epoxide xanthophylls, neoxanthin, traces of violaxanthin and trace amounts of isomers of each were found in broiler skin.…”

Xanthophyll depleted, fasted broilers were intubated with various xanthophyll sources in a series of six experiments. The increase in serum xanthophyll per milligram xanthophyll intubated per kilogram body weight was used to estimate exahtnophyll availability. Statistically significant differences among samples within and among generic sources were obtained. As a result, beta-apo-8'-carotenoic acid ethyl ester (apo-EE) was used as a reference standard in Experiments 4 to 6. When the availability of apo-EE was given a relative value of 100, the availability of xanthophyll from corn gluten meal ranged from 47.7 to 89.1% (four samples), from dehydrated alfalfa, 34.6 to 65.4% (eight samples), and from Coastal Bermudagrass, 18.8 to 27.9% (three samples).
