“…For increasing the accuracy of the determined phenotype or temperament type, the combination of behaviour records and physiological and endocrinological parameters are used in behaviour studies. Measurements of cortisol and heart rate are often used to measure the activity of the hypothalamicpituitary-adrenal axis and sympatho-adrenal medullary system as supplementary indicators for the stress response in cattle (Grignard et al, 2001;King et al, 2006;Curley Jr. et al, 2008;Burdick et al, 2010;Cafe et al, 2011a). Higher heart rates and cortisol levels indicate more excitable or tem-peramental cattle.…”

“…Likewise in cattle, parameters of the HPA axis activity were shown to be correlated to cattle temperament. Temperamental heifers were found to have higher baseline cortisol concentrations than calmer animals (Curley Jr. et al, 2008). A detailed investigation of the genetic correlation between behaviour and HPA axis parameters could be a valuable approach to identify relevant pathways and physiological responses resulting from the genetic predisposition of temperament.…”

Abstract.Cattle temperament, which describes individual behaviour differences with regard to a stressor or environmental challenge, is known for its impact on working safety, adaptability to new housing conditions, animal productivity and for evaluation of animal welfare. However, successful use of temperament in animal breeding and husbandry to improve keeping conditions in general or animal welfare in particular, requires the availability of informative and reproducible phenotypes and knowledge about the genetic modulation of these traits. However, the knowledge about genetic influences on cattle temperament is still limited. In this review, an outline is given for the interdependence between production systems and temperament as well as for the phenotyping of cattle temperament based on both behaviour tests and observations of behaviour under production conditions. In addition, the use of temperament as a selection criterion is discussed.

“…Stressors activate the hypothalamus-pituitary-adrenal (HPA) axis that stimulates the adrenal glands to release hormones including cortisol, epinephrine and noradrenalin (12,13). High levels of blood cortisol provoke immunosuppression, rendering the cattle more susceptible to infectious diseases (12,14).…”

This study determined the correlation between serum cortisol levels and rabies antibody titers in cattle primo-vaccinated against rabies and supplemented with dietary selenium (Se). Sixty Nelore male calves (10 to 12 months old) received daily and individual dietary supplementation with 0, 3.6, 5.4 and 6.4 mg Se (groups Gc, G 3.6 , G 5.4 and G 6.4 , respectively). The animals were vaccinated against rabies (day 0) and subjected to handling stress in the corral for 120 days. Blood sampling procedures were performed on days 0, 15, 30, 60, 90 and 120. Cortisol levels increased until day 90, but had dropped significantly by day 120 (P < 0.01). Rabies antibody titers on days 30 and 90 were similar among Sesupplemented groups; in the control group, rabies antibodies decreased significantly from day 30 to 60, and 90 to 120. Serum cortisol levels and antibody titers were not correlated in most of the groups or blood sampling days. A positive correlation among these variables was found only in G 6.4 on days 60 (R = 0.513; P = 0.05) and 120 (R = 0.644; P = 0.009). In conclusion, repeated handling in the corral stresses cattle, but without compromising rabies humoral immune response.

“…It is thus questionable whether discrepancies between these studies are due to the lack of standards in experimental designs using exercise as stressor, or individual-related factors are responsible for the variability of results. Although several studies have shown that HPA activity and responses to usual stressors can differ with temperament in production animals (Curley et al, 2008;Pajor et al, 2013;Kovács et al, 2016), it is still unclear whether cortisol level could be influenced by temperament in horses. Therefore, the aim of this study was to bring researchers one step closer to answering the question whether cortisol response in Thoroughbred horses to a single exercise bout differs with temperament.…”

Temperament has not been taken into account in previous studies evaluating the stress response to exercise in horses. The aim of the present study was to investigate the cortisol response in Thoroughbred racehorses to a single exercise bout, and to analyse the results based on the basic personality of the horse examined. Twenty healthy Thoroughbred horses were selected for the study based on a 25-item rating questionnaire survey used for characterising equine temperament. Eight temperamental and twelve calm horses took part in the experiment. The horses trotted as a warm-up activity, and then galloped on a rounded sand track. Blood sampling was conducted four times for each horse. Horses with a more excitable temperament showed a higher cortisol response to the test (P = 0.036). In conclusion, cortisol levels in response to a mild intensive exercise can be affected by temperament in horses. Serum cortisol may be a relevant marker to quantify individual temperamental differences in racehorses.
