Carotenoid Modulation of Immune Function and Sexual Attractiveness in Zebra Finches
It is shown that manipulation of dietary carotenoid supply invokes parallel changes in cell-mediated immune function and sexual attractiveness in male zebra finches (Taeniopygia guttata).
Effect of selenium and vitamin E content of the maternal diet on the antioxidant system of the yolk and the developing chick
It is concluded that the nutritional status of the laying hen determines the efficiency of the antioxidant system throughout embryonic and early postnatal development of the offspring.
Maternally derived androgens and antioxidants in bird eggs: complementary but opposing effects?
It is shown that within-clutch variation in yolk testosterone is the opposite to that of yolk antioxidant concentration in the lesser black-backed gull Larus fuscus, and evidence is provided that these two direct maternal effects are complementary and, in conjunction with an indirect maternal effect (the onset of incubation), may provide an adaptive mechanism for parental favoritism in response to environmental variability.
Carotenoids and egg quality in the lesser black-backed gull Larus fuscus: a supplemental feeding study of maternal effects
The results suggest that carotenoids could be one resource responsible for egg quality maternal effects in birds, and the possible implications of carOTenoid–mediated effects on phenotype for fitness in mothers and their offspring are discussed.
Selenium content in selected foods from the Greek market and estimation of the daily intake.
The total selenium content of foods purchased from the North West part of Greece was determined using hydride generation atomic fluorescence spectroscopy. The results of this study were within the
Viability, susceptibility to peroxidation and fatty acid composition of boar semen during liquid storage.
It is concluded that the alphaT inclusion in the boar semen diluent increased cell viability through its prevention of an oxidative reduction in the levels of the major polyunsaturated fatty acids, namely 22:6n-3.
