Table 6.
P-values and LSmeans of the line effect of behavioral recordings (N = 72).
| Line effect | LSmeans | ||
|---|---|---|---|
| Open field | P | Low-RFI line | High-RFI line |
| Number of zones visited | ns | 19 ± 2 | 24 ± 2 |
| Number of vocalizations | * | 117 ± 9a | 90 ± 9b |
| Number of long breaths | ns | 0.2 ± 0.1 | 0.4 ± 0.1 |
| Number of body shaking | ns | 1.4 ± 0.2 | 1.6 ± 0.2 |
| Number of wing flapping | ns | 2.2 ± 0.2 | 2.0 ± 0.2 |
| Response to the presence of human | |||
| Latency to the first immobilization (s) | ns | 6.2 ± 0.4 | 5.8 ± 0.4 |
| Number of zones visited | ns | 4.7 ± 0.4 | 5.2 ± 0.4 |
| Number of long breaths | ns | 0.4 ± 0.1 | 0.6 ± 0.1 |
| Number of vocalizations | * | 41 ± 3a | 50 ± 3b |
| Number of beak opening | ** | 5.1 ± 0.5a | 2.6 ± 0.5b |
Behavioral traits recorded during the open field test lasting 5 min and the response to the presence of human test lasting one min. Least square means (LSmeans) ± SE were estimated.
In a row, values with different superscripts (a, b) were found to be significantly different (P < 0.05) for the line effect.
*: P < 0.05; **: P < 0.01; ***: P < 0.001
