Resumen
Abstract
The aim of this study was to identify and analyse the social strategies associated with dominance, conflict resolution, individual behaviour and morphological traits in goats. Social
interactions of 30 high-yielding dairy goats were recorded over a period of 16 days for 96 h.
The variables measured were social interactions, conflict resolution, individual behaviours
and morphological characteristics. Using seven variables of social interactions, through
the test of factor analysis three factors were obtained that concentrated the 92.3% of the
variance. These were labelled as ‘avoider’ factor (36.9%), ‘no-agonistic’ factor (28.1%) and
‘agonistic’ factor (27.3%). Subsequently a hierarchical cluster analysis was performed in
order to identify identity profiles (groups of similar animals) which could help to explain
the possible association between social strategies (obtained from the factor analysis) and
index of success, conflict resolution, social and individual behaviour and morphometric
characteristics. Social strategies, dominance, conflict resolution, and the time they devote
to feeding and resting, beard length, thoracic circumference and the particular association
of each one of these characteristics has allowed us to identify four types of identity profiles
which we have termed aggressive, affiliative, passive, and avoiders. Our results show the
existence of an association between social strategies with identity profiles in dairy goats.
We propose the use of term identity profile for describe individuality, personality and their
relationship with certain morphological traits of the animals.
