Özet

The study was carried out to investigate the effect of adding lutein, alfalfa meal, marigold meal, paprika meal, beta-apo-8'-carotenoic acid ethyl ester, canthaxanthin and beta-apo-8'-carotenoic acid ethyl ester+canthaxanthin (3:1) on egg yolk pigmentation and production in white corn and wheat diets. The maximum Roche color fan (RCF) value was found in canthaxanthin and the mixture of beta-apo-8'-carotenoic acid ethyl ester and canthaxantin. The maximum beta-carotene equivalent (BCE) value was found in beta-apo-8'-carotenoic acid ethyl ester. The maximum Hunter L value was found in the control and lutein. The maximum Hunter a value was found in paprika meal. The maximum Hunter b value was found in beta-apo-8'-carotenoic acid ethly ester and alfalfa meal (P<0.01). There were no significant differences among the groups for egg production, egg weight and weight gain (P>0.01).
