The Effect Of Natural And Synthetic Carotenoids On Pigmentation Of Gold Fish (Carassius Auratus), Mahmut Yanar, Nazmi̇ Tekeli̇oğlu
Turkish Journal of Veterinary & Animal Sciences
In this study, the effect natural end synthetic carotenoids on pigmentation of gold fish (Carassius auratus) was investigated. The fish were fed on diets containing 75 mg/kg zeaxanthin, astaxanthin, zeaxanthin+astaxanthin, 6% alfalfa, red pepper, carrot or plankton (Daphnia spp. and Scenedesmus spp.). At the end of the 60 days of experimental period, total carotenoid accumulation in the skin of the fish fed the experimental diets were 33.52±0.62 mg/kg for zeaxanthin, 29.84±0.50 mg/kg for red pepper, 27.07±0.62 mg/kg for Daphnia spp., 26.52±0.42 mg/kg for Scenedesmus spp., 25.84±0.62 mg/kg for astaxanthin+zeaxanthin, 23.95±0.68 mg/kg for astaxanthin, 19.95±0.66 mg/kg for carrot, 16.58±0.64 mg/kg for …

The Effects Of Some Natural And Synthetic Pigment Materials On Egg Yolk Pigmentation Andproduction In Yellow Corn Diets, Figen Kirkpinar, Ramazan Erkek
Turkish Journal of Veterinary & Animal Sciences
The study was carried out to investigate the effect of lutein, alfalfa meal, marigold meal, paprika meal, \beta-apo-8'-carotenoic acit ethyl ester, canthaxanthin and \beta -apo-8'-carotenoic acit ethyl ester+canthaxanthin in addition to 60% yellow corn diets on egg yolk pigmentation and production. Paprika meal showed the maximum Roche color fan value (RCF). \beta -apo-8'-carotenoic acit ethyl ester, alfalfa meal and marigold meal showed the highest \beta -carotene equivalents value (BCE). The maximum Hunter L value was found in the control group. Paprika meal showed the maximum Hunter a value. Lutein had the highest Hunter b value (P0.01).
The Effects Of Some Natural And Synthetic Pigment Materials On Egg Yolk Pigmentation Andproduction In White Corn And Wheat Based Diets, Figen Kirkpinar, Ramazan Erkek
The Effects Of Some Natural And Synthetic Pigment Materials On Egg Yolk Pigmentation Andproduction In White Corn And Wheat Based Diets, Figen Kirkpinar, Ramazan Erkek
Turkish Journal of Veterinary & Animal Sciences
The study was carried out to investigate the effect of adding lutein, alfalfa meal, marigold meal, paprika meal, ?-apo-8'-carotenoic acid ethyl ester, canthaxanthin and ?-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 ?-apo-8'-carotenoic acid ethyl ester and canthaxantin. The maximum ?-carotene equivalent (BCE) value was found in ?-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 …
