We assessed motor laterality in sheep to explore species-specific brain hemi-field dominance and how this could be affected by genetic or developmental factors. Further, we investigated whether directionality and strength of laterality could be linked to emotional stress in ewes and their lambs during partial separation. Forty-three ewes and their singleton lambs were scored on the (left/right) direction of turn in a y-maze to rejoin a conspecific (laterality test). Further, their behavioural response (i.e. time spent near the fence, vocalisations, and activity level) during forced separation by an open-mesh fence was assessed (separation test). Individual laterality was recorded for 44.2 % ewes (significant right bias) and 81.4 % lambs (equally biased to the left and the right). There was no significant association in side bias between dams and offspring. The Chi-squared test revealed a significant population bias for both groups (p < 0.05). Evolutionary adaptive strategies or stimuli-related visual laterality may provide explanation for this decision-making process. Absolute strength of laterality (irrespective of side) was high (Kolmogorov–Smirnov test, dams: D = 0.2; p < 0.001; lambs: D = 0.36, p < 0.0001). The Wilcoxon test showed that lateralised lambs and dams spent significantly more time near each other during separation than non-lateralised animals (p < 0.05), and that lateralised dams were also more active than non-lateralised ones. Arguably, the lateralised animals showed a greater attraction to their pair because they were more disturbed and thus required greater reassurance. The data show that measures of laterality offer a potential novel non-invasive indicator of separation stress.

This work investigated the differences in the reactivity of Sarda (primiparous n= 18, multiparous n= 17) and Dorset (multiparous n= 8) breeds of sheep and their singleton lambs to two challenging test situations involving a mother-lamb partial separation test and an isolation test. Non-parametric analysis used single behavioural variables and fear scores to evaluate the effect of parity, sex of lambs, and the association between mother-lamb behaviour. Amongst ewes, Dorset were characterised by a more calm temperament while Sarda (especially primiparous ewes) were more active in their response to challenge (i.e. more attempts to escape). As with their dams, lambs reflected to a certain extent this divergence and overall during isolation lamb fear score was on average significantly higher than dams. Correlations between measures of behavioural reactivity across tests were carried out to search for predictive measures of fear. A very strong correlation emerged linking vocalisation to locomotor activity. Vocalisation could be a good candidate as predictor factor of an active reaction of sheep to a fearful situation.

Introduction: The attachment related difficulties of Looked after Children are well recognised in literature with difficulties linked to early experiences hypothesised to be perpetuated by experiences of the care system itself. Recent policy guidelines have emphasised the importance of relationships for children in care, one of the most important being with their primary carer. Golding (2014) published a group format training resource entitled ‘Nurturing Attachments’ which aims to promote ‘therapeutic parenting’; however there is limited knowledge on the feasibility of this intensive approach.
Aims: To assess the feasibility of Nurturing Attachments through exploring (i.) recruitment, retention and attrition, (ii.) initial outcomes, (iii.) acceptability and (iv.) ability of the programme to be delivered in line with the manual content and structure.
Method Two Health and Social Care Trusts in NI participated in the study by facilitating a Nurturing Attachments group in each site with adoptive parents, foster carers and kinship carers (N = 26). Carers completed pre and post measures to explore initial outcome, completing an evaluation questionnaire to explore acceptability. Acceptability was also explored with Trust stakeholders and group facilitators through focus group and interview. To explore if the manual can be delivered as intended, each group completed debrief tools.
Results: The overall response rate for uptake was 13.9%, which impacted on engagement for a ‘treatment as usual’ group. Once engaged in the programme, attrition was low and attendance was high. Initial outcomes have shown positive effects for both young person and carers. Feedback suggests a positive response regarding acceptability with limited expressed concern. The manual can be delivered in a standardised way; however can be flexible enough to allow for group processes.
Conclusions: Further research is needed to continue to explore efficacy, however the current study has provided supporting evidence that Nurturing Attachments as an intervention has positively impacted on many levels of the LAAC system.
