Stress-induced behaviour was recorded for 3 min and spontaneously occurring dyskinetic behaviours were scored using the AIMs scale.
The latency of the first episode of immobility, the total duration of this behaviour, and mean velocity were scored using Noldus EthoVision XT 8.5 (Noldus Information Technology, Wageningen, Netherlands) according to the protocol that was previously validated [ 41].
The goats were video recorded for 48 h in the end of each experimental period and the behaviour and position in the pen were scored using instantaneous sampling at 15 min intervals.
Alleles were scored using GeneMarker.
Uék's behaviour was scored from videotape by JHW.
Freezing behaviour was scored as previously described.
Typical behaviour is scored as 0, whereas the absence of normal behaviour or the presence of abnormal behaviour is rated as 1.
Videos were recorded in.mov format and behaviour was manually scored using JWATCHER v1.0 [ 59].
These items were repeated for the three behaviour sections and scored using a 7-point Likert scale.
Mother child interactions were videotaped and systematically scored using the Maternal Behaviour Q-Sort (MBQS -25 iteMBQS -25andarditemsmeastandardizedrnal sensitivity.
