Retention of carotenoids in egg yolks of laying hens supplemented with heterotrophic Chlorella

Popis výsledku v původním jazyce

The present study investigated the effect of 1% and 2% feed supplementation with biomass of Chlorella grown through heterotrophic fermentation on the concentration of total and individual carotenoids in egg yolks. A total of 24 Hisex Brown laying hens aged 56 weeks were included in the experiment. The layers were kept individually in cages. They were divided into three groups of eight birds and fed with a mixed feed for laying hens. Control birds (C) received only mixed feed, while experimental diets (P1 and P2) were supplemented with 1% and 2% (i.e. 10 and 20 g/kg) dry disintegrated Chlorella biomass. Egg yolk deposition of total carotenoids was significantly (P{0.01) increased by 46% (P1) and 119% (P2). The rising curves of total carotenoids reachedtheir plateau during the 4th experimental week. The respective values varied near 25ug (P1) and 40 ug (P2) per gram of yolk during the following weeks. Lutein and zeaxanthin were equally deposited and they represented more than 90% of tot
