From: The distribution of carotenoids in hens fed on biofortified maize is influenced by feed composition, absorption, resource allocation and storage

Figure 2

Carotenoid levels in the yolk of eggs laid by hens after 31 days on four different diets (WT = wild-type M37W maize, HC = high-carotenoid maize, BKT = ketocarotenoid maize, COM = commercial yellow maize plus retinol).

Values are means in μg/g freeze dried (fd) ± SE from 3–5 independent samples (biological replicates). Individual carotenoids are shown (neox = neoxanthin, viol = violoxanthin, lut = lutein, zeax = zeaxanthin, α-cry = α-cryptoxanthin, β-cry = β-cryptoxanthin, β-car = β-carotene, C427 = most likely β-cryptoxanthin-5,8-epoxide, astax = astaxanthin) as well as the total levels of pro-vitamin A (PVA) and non-PVA carotenoids.
