Název v původním jazyce

Maternal carotenoid supplementation does not affect breeding performance in the Great Tit (Parus major)

Popis výsledku v původním jazyce

Carotenoids are micronutrients with many beneficial health-related effects. They are effective antioxidants and stimulants of the immune system. Carotenoids cannot be synthesized in animals and must be obtained from food. As such, they may limit reproductive output and performance, and on the proximate level mediate reproductive trade-offs. We studied carotenoid limitation in wild Great Tits (Parus major) by supplementing prelaying and laying females with lutein, the most abundant carotenoid in this species. We followed the effects of this supplementation on egg yolk carotenoid composition, and offspring and parental performance. Females transferred the supplemented lutein into egg yolks, increasing lutein concentration to the upper limit of naturallyoccurring concentrations in control pairs. Concentrations of zeaxanthin, ?-carotene and ?-carotene did not differ between supplemented and control pairs. Effects on offspring and parental performance were generally absent or weak. There w
