Comparison of the total time spent eating during the 3-min choice test with menhaden and the familiar food, and the 3-min choice test with menhaden and the unfamiliar food.

<p>Paired <i>t-</i>test, **<i>P</i><0.01.</p

Comparison of the behavior of control (<i>n</i> = 24 pairs) and MH chicks (<i>n = </i>24 pairs) in the 3-min choice test with menhaden and unfamiliar food.

<p>(A) Mean ± SEM latency score to explore the odorized unfamiliar food. (B) Mean ± SEM latency score to ingest the odorized unfamiliar food. (C) Mean ± SEM proportion of time spent eating the odorized unfamiliar food. ANOVA, *<i>P</i><0.05.</p

Growth and feed intake of chicks.

<p>All data are represented as Means ± SEM mass of MHchicks (n = 48) and control chicks (n = 48) and daily intake measured in pairs of chicks. Different superscript letters indicate significant differences in paired <i>t-</i>tests (<i>P</i><0.05).</p

Morpho-physiological measurements of adult hens before and during treatment.

<p>All data are represented as mean ± SEM (<i>n = </i>20). Paired <i>t-</i>test (comparison with “before treatment”):</p>*<p><i>P</i><0.05,</p>**<p><i>P</i><0.01.</p

Mean ± SEM tonic immobility duration (s) in chicks.

<p>MH chicks (<i>n = </i>48) and control chicks (<i>n</i> = 48); ANOVA, *<i>P</i><0.05, **<i>P</i><0.01.</p

Preferences within control and MH chicks for the odorized or non-odorized unfamiliar food.

<p>(A) Mean ± SEM time spent eating each type of food. (B) Mean ± SEM number of feeding sequences on each type of food. Paired <i>t-</i>test, *<i>P</i><0.05, **<i>P</i><0.01.</p

Olfactory evaluation of egg yolks.

<p>Data represent the number of panelists who detected menhaden odor in each vial.</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

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 duration of tonic immobility (TI).

<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 short (STI) and long (LTI) duration of TI and the non-selected control line (CTI). Different letters above columns indicate significant differences between lines at the level of <i>p</i><0.05. b^* indicates <i>p</i> = 0.057.</p
