Extract

Modern cattle management systems involve animals’ separation from penmates for procedures such as weighing, measuring and blood-sampling. This separation can result in distress in some individuals. Environmental and genetic factors are known to control the variability observed in behavioural responses of different individuals. We carried out a genome scan in a Holstein x Charolais cross population to identify QTL influencing temperament-related traits. One of these tests was the social separation test (SS test), which was designed to measure animals’ fearfulness to social separation (Ball et al., 2002). We present here the results obtained for the traits scored in the SS test performed in the heifers of the second-generation of this population.
