Priming effects of yolk T

Effects of a yolk testosterone manipulaiton on the yolk T deposition (pg / mg yolk) of females that developed in the manipulated eggs, and their daughters

Statistical analysis (hierarchical ANOVA with fixed effect of line and random effect of female nested within the line) of maternal antibodies (IgY) in the yolk and albumen lysozyme performed separately within genetic selection for the duration of tonic immobility, social reinstatement behaviour and yolk testosterone concentrations in Japanese quail.

Egg compounds in Japanese quail selected for contrasting yolk testosterone (T) levels.

<p>Data represent means (± SE) of yolk T (A), yolk immunoglobulins, IgY (B) and albumen lysozyme (C) concentrations (upper row) and total egg content (bottom row) in the high (HET) and low (LET) egg T lines. Different letters above columns indicate significant differences between lines at the level of <i>p</i><0.05.</p

Egg compounds in Japanese quail selected for contrasting social reinstatement (SR) behaviour.

<p>Data represent means (± SE) of yolk T (A), yolk androstenedione, A₄ (B), yolk progesterone, P₄ (C), yolk immunoglobulins, IgY (D) and albumen lysozyme (E) concentrations (upper row) and total egg content (bottom row) in the lines selected for high (HSR) and low (LSR) SR behaviour and the non-selected control line (CSR). Different letters above columns indicate significant differences between lines at the level of p<0.05.</p
