Popis:	Scores for four behavioural traits – aggressiveness, ferocity, face hiding and nobility – recorded between 1984 and 2010 in Lidia bovine breed (the property of a single breeder in Spain), were analysed using the multi-trait and reaction norm models. The multi-trait analysis results revealed heritability values of between 0.23 for nobility and 0.33 for ferocity. Principal components analysis of the genetic correlation matrix identified two factors that explained 91.6% of the total variance. Reaction norm analysis revealed genetic correlation values across sexes and time to be
