Developing and validating measures of temperament in livestock
Proceedings of the Manitoba Swine Seminar, Manitoba, Feb.
The human animal relationship, its implications for pig welfare and productivity and training strategies to safeguard pig welfare.
The long-term longitudinal study enabled clarification of the relationship between responses of heifers to first machine milking and their earlier responses to behavioural tests.
In this general discussion, I will consider the results in a wider context, and also specifically focus on (i) the multidimensional nature of response patterns to stress, (ii) the significance of individual differences in stress responsiveness in (farm) animals, and (iii) some practical implications of the findings of this thesis.
Most of the instruments reviewed (48/52) were disease-specific rather than generic.
Only four publications provided a definition of Qo L or wellbeing.
The average temperament score (±s.e.m.) of the Corriedale lambs was 24.7 (±0.23) and that of the Merino was 36.8 (±0.45).
The basic premise of these concepts is that animals exhibit consistent individual differences in behavioural and physiological responses across a wide range of different environmental challenges.The main aim of the work described in the present thesis was to examine the consistency of individual differences in behavioural and physiological responses to acute stressors in dairy cattle in a longitudinal fashion, i.e. Information about the variation in the reactivity of dairy cattle to a “real-life” challenge was provided by a study of heifers’ responses to first-time machine milking.
