Quail’s reactivity to a novelty.

<p>(A) Reactivity to a novel object: The latency to peck at the novel object was higher for the LTI quail compared to the STI quail, and it tended to increase with the exposure to URNS when considering all the quail. Data represent mean+se. Mann-Whitney U tests: NS, P≥0.1. (B) Reactivity to a novel food: The genetic line did not influence the amount of novel food consumed by the quail, but the exposure to URNS decreased the amount of novel food consumed in STI quail. Data represent mean+se. Two-way ANOVA: **, P<0.01; NS, P≥0.1. (C) Reactivity to a novel environment: The STI quail spent less time in the center of the open field compared to the LTI quail. The exposure to URNS induced an increase of the time spent in the center of the open field in STI quail, but had no effect on LTI quail. Data represent mean+se. Mann-Whitney U tests or Fisher’s test: *, P<0.05; NS, P≥0.1. White bars: control group. Black bars: disturbed group.
