“…This finding agrees with the results of a number of other recent studies, which suggest that individual personal traits may significantly modify behavior and physiological response in wide range of species including horses (Hausberger et al, 2004;Henry et al, 2007;Ijichi et al, 2013;LeScolan et al, 1997).…”

a b s t r a c tArtificial weaning is often highly stressful for both mother and offspring. We investigated the effect of 2 different weaning and relocation schedules on growth rate and saliva cortisol concentrations in a group of loose-housed domestic horses. We predicted higher acute stress (cortisol concentrations), but a lower long-term effect on weight gain, which would indicate lower chronic stress in foals, if the foals were moved to the new environment immediately after separation from the mothers ("prompt relocation" [PR]) compared with relocation that was adjourned for a week ("stepwise relocation" [SWR]). Within 2 seasons, 56 foals weaned at age of 165-250 days were regularly weighed up to 140 days after weaning. Growth rate significantly differed between SWR and PR foals. The PR weanlings revealed relatively stable increase in their weights, whereas SWR foals experienced a significant drop in growth during the first 3 weeks after weaning. The weight differences were still apparent 5 months after weaning (predicted weight, least squares means AE standard error: 374.40 AE 1.75 kg in PR vs. 362.71 AE 1.66 kg in SWR foals). Cortisol concentrations changed significantly between and within different weaning procedures and were highest in PR foals after weaning and relocation. Compared with pre-weaning values, cortisol levels increased in PR but not in SWR foals, either after weaning or deferred moving. We found large individual variability in foals' growth and in cortisol concentrations for both weaning procedures. There was also a year effect in SWR foals. Stepwise changes of the physical and social environment (deferred removal to the remote facility) within a short period after abrupt weaning resulted in lower acute stress but induced long-term negative effects on foals' growth rate compared with joint weaning and relocation. Our results support rather prompt moving of the weanlings to the new facility, rather than to a stepwise location on horse breeding farms.

“…All animals were recruited through direct contact from private owners (n=40), and were kept at various locations in Gloucestershire and Wiltshire, in the South West of England during the study period (June 2014-January 2015). In addition, these animals differed in terms of management regime, breed (ranging from native breeds to sport horses) and use (from leisure to polo and competition disciplines such as polo and dressage) in order to source a representative crosssection of the UK horse population with the level of variance favoured for Principal Component Analysis (Ijichi et al, 2013). As such, selection criteria required that the horse was free from acute clinical disease (excluding dopamine pathology) and able to be led from a head collar and lead rope (Ijichi et al, 2013).…”

“…This approach would however need to proceed mindful of the balance between genotypic determination of temperament and subsequent environmental modification of behavioural output. Whilst temperament and 96 personality type research has been conducted in horses (for example see Momozawa et al, 97 2003;Momozawa et al, 2005a;Lloyd et al, 2007, Nagy et al, 2010Ijichi et al, 2013), the 98 way in which the result of this relates to dopaminergic function has yet to be determined 99 empirically. Interestingly however, Momozawa et al (2005b) observed a significant relationship between DRD4 (dopamine D4 receptor subtype) single nucleotide polymorphism, an A-G substitution causing an amino acid change from asparagine to aspartic acid (Hori et al, 2013).…”

1 mtA-elte comparative ethology research group, budapest, hungary 2 department of psychology, university of texas, Austin, tX, usA 3 school of psychologial sciences, university of melbourne, parkville, vic 3010, Australia 4 department of ethology, eötvös university, budapest, hungary (received: march 5, 2014; accepted: June 26, 2014) the aim of the present study was to examine the links between independent rating and coding approaches to assessing activity-impulsivity and inattention in dogs. fifty-six adult belgian shepherd dogs were videotaped performing in behavioural tests. seventeen behavioural variables were measured by coders (video coding). raters watched the same videotapes and then rated the activity-impulsivity and inattention of each dog (video rating). Owners filled out the Dog ADHS-RS questionnaire measuring activityimpulsivity and inattention. video rating of activity-impulsivity correlated with the scale scores of the owner, but video codings did not. the results suggest that the owner ratings and video ratings are tapping the same constructs, but behavioural variables assessed in the present study were not appropriate for mirroring the owners' assessments. The findings suggest that if consistent individual differences in broad behavioural traits are the primary focus of analyses, then ratings seem to capture information not easily captured in coding approaches designed to assess the same constructs.
