  Title Physiological response to the first saddling and first mounting of horses: comparison of two sympathetic training methods Type Journal Article
  Year 2014 Publication Animal Science Papers and Reports Abbreviated Journal  
  Volume 32 Issue 3 Pages 219-228  
  Keywords cortisol / emotional reaction/ horses / natural training / stress  
  Abstract There is not much research done on the influence of sympathetic training on the emotional reaction

of horses. The aim of the present study was to evaluate the emotional response and the stress level

in horses to two sympathetic training methods: (1) with the use of the “round pen technique” (RP),

and (2) in which the RP was not applied (SH). Twenty two half-bred Anglo-Arab horses (2.5

years ±3 months of age) were subject to an initial training. Eleven horses were randomly included

to the RP method and the other 11 horses for the SH method. Heart rate (HR) and saliva cortisol

concentration were measured as indicators of horse emotional arousal and stress level, respectively.

The HR values were analysed: at rest, during the habituation period, just after the first saddling

and tightening of the girth, during the first time a human leaned over the horse’s back, and during

the mounting of the horse. Saliva samples were taken before and 15 min after each training session

studied. After saddling, the HR occurred significantly higher when the RP technique was used. The

significant increase in saliva cortisol concentration was observed only after the first mounting of

the horse. Generally, the use of the RP technique did not involve more important physiological

reactions in the trained horses than did the SH method.

  Title Cortisol levels in hair reflect behavioural reactivity of dogs to acoustic stimuli Type Journal Article
  Year 2013 Publication Research in Veterinary Science Abbreviated Journal  
  Volume 94 Issue 1 Pages 49-54  
  Keywords Dogs; Behaviour; Cortisol; Hair; Acoustic stimuli  
  Abstract Cortisol levels in hair samples were examined in fourteen domestic dogs and related to the dogs’ responses to different acoustic stimuli. Stimuli were playbacks of species-typical vocalizations recorded during three different situations (“disturbance”, “isolation” and “play” barks) and the sounds of a thunderstorm. Hair samples were collected at 9:00 h and 17:00 h two weeks after the behavioural tests. Results showed that behavioural reactivity to playback of the various stimuli correlates with cortisol levels in hair samples collected at 9:00 h, and the same was the case for the separate measures of behaviour (i.e. hiding, running away, seeking attention from the tester, panting and lowering of the body posture). Hence, levels of cortisol in hair appear to reflect the dog’s chronic state of emotional reactivity, or temperament.

  Title Immunological response to long-term transport stress in mature horses and effects of adaptogenic dietary supplementation as an immunomodulator Type Journal Article
  Year 2004 Publication Equine Veterinary Journal Abbreviated Journal  
  Volume 36 Issue 7 Pages 583-589  
  Keywords horse; transportation; Cd+; lymphocytes; stress; cortisol; adaptogens  
  Abstract Reasons for performing study: Little information exists on the immunological effects of transport or the use of supplements to minimise transport stress. Objectives: To establish baseline ranges and evaluate immunophenotypic and functional changes associated with transport and a nutritional ‘adaptogen’ supplement. Methods: Horses received either supplement (n = 10) or placebos (n = 9) during the 30 day study. After 28 days in stalls, 12 horses (6 supplement; 6 placebo) were transported for 24 h, then unloaded and recovered. Venous blood samples were collected on Days 1, 14 and 28 to establish baselines, and on Days 28, 29 and 30 to examine changes during transport and recovery. Results: Transport prompted elevations (P<0.05) in cortisol concentration, neutrophil count and white blood cell counts, while lymphocyte subpopulation counts (CD3+, CD4+, CD8+, CD21+) decreased (P<0.05). Normal phenotypic lymphocyte profiles returned within 24 h of recovery. Supplement effects on immunophenotype (CD21+ and CD8+) were observed in stabled horses (P<0.05), but not in transported horses. Conclusions: These results provide insights into the immunological mechanisms associated with long-term transport. Potential relevance: The existence of a small window of immunological uncertainty follows long-term transportation, enhancing the potential risk of infectious disease in susceptible individuals.

  Title Effects of season, age, sex and housing on salivary cortisol concentrations in horses Type Journal Article
  Year 2015 Publication Domestic Animal Endocrinology Abbreviated Journal Domest. Anim. Endocrinol.  
  Volume Issue Pages  
  Keywords horse; cortisol; diurnal rhythm; reproduction; housing  
  Abstract Abstract Analysis of salivary cortisol is increasingly used to assess stress responses in horses. Since spontaneous or experimentally induced increases in cortisol concentrations are often relatively small for stress studies proper controls are needed. This requires an understanding of factors affecting salivary cortisol over longer times. In this study, we have analysed salivary cortisol concentration over 6 mo in horses (n = 94) differing in age, sex, reproductive state and housing. Salivary cortisol followed a diurnal rhythm with highest concentrations in the morning and a decrease throughout the day (P < 0.001). This rhythm was disrupted in individual groups on individual days; however, alterations remained within the range of diurnal changes. Comparison between months showed highest cortisol concentrations in December (P < 0.001). Cortisol concentrations increased in breeding stallions during the breeding season (P < 0.001). No differences in salivary cortisol concentrations between non-pregnant mares with and without a corpus luteum existed. In stallions, mean daily salivary cortisol and plasma testosterone concentration were weakly correlated (r = 0.251, P < 0.01). No differences in salivary cortisol between female and male young horses and no consistent differences between horses of different age existed. Group housing and individual stabling did not affect salivary cortisol. In conclusion, salivary cortisol concentrations in horses follow a diurnal rhythm and are increased in active breeding sires. Time of the day and reproductive state of the horses are thus important for experiments that include analysis of cortisol in saliva.

  Title Quantification of stress sensitive markers in single fecal samples do not accurately predict excretion of these in the pig Type Journal Article
  Year 2007 Publication Research in Veterinary Science Abbreviated Journal  
  Volume 82 Issue 3 Pages 423-428  
  Keywords Cortisol; Immunoglobulin A; Stress; Pigs; Feces; Animal welfare  
  Abstract All feces produced during 24 h were collected from five pigs and cortisol and immunoreactive cortisol metabolites (CICM), and IgA were quantified. Within pigs, the concentrations of CICM and IgA varied extensively between random samples obtained from a single fecal dropping, and deviated in most cases significantly from the true concentration measured in total fecal output (CV 6.7–130%). The CICM and IgA contents varied considerably (CV 8.1–114%) within and between individual fecal droppings from the same pig compared to the total fecal excretion. In conclusion, single random samples could not be used to reliably quantify the total fecal concentration or excretion of CICM or IgA in pigs. Analyses of all feces collected during shorter periods than 24 h did not provide an accurate estimate of the daily excretion of CICM. Thus, the concentration of stress sensitive molecules in random single fecal samples as an indicator of animal welfare should be interpreted with prudence.

  Title Urinary and fecal immunoglobulin A, cortisol and 11-17 dioxoandrostanes, and serum cortisol in metabolic cage housed female cynomolgus monkeys (Macaca fascicularis) Type Journal Article
  Year 2007 Publication Journal of Medical Primatology Abbreviated Journal  
  Volume 36 Issue 6 Pages 355-364  
  Keywords cortisol; cynomolgus monkey; immunoglobulin A; long tailed macaque; Macaca fascicularis; metabolism cage  
  Abstract Background and methods Quantitative enzyme-immunoassays of urinary and fecal immunoglobulin A (IgA), cortisol and 11-17-dioxoandrostanes (11,17-DOA), and serum cortisol in eight metabolic-cage-housed female cynomolgus monkeys were performed. The monkeys were divided into two groups, B and NB. Group B animals were blood sampled every 6 hours, whereas Group NB animals were not handled/blood sampled. Results No differences were recorded between the amounts of feces and urine excreted by the two groups. Group B animals excreted more urinary cortisol than did Group NB animals indicating that restraint-blood sampling resulted in a stress response. Excreted amounts of IgA and 11,17-DOA (urine and feces) did not differ between the groups. Conclusions Urinary cortisol was a reliable marker of the stress associated with repeated blood sampling. Declining amounts of excreted urinary cortisol indicated that cynomolgus monkeys acclimated quickly to repeated blood sampling in metabolism cages. Within and between animal variation in amounts of feces voided demonstrated the importance of expressing fecal markers as ‘amounts excreted per time unit per kg body weight’ rather than just measuring the concentrations in fecal samples.

  Title Does housing in a „social box“ change faecal cortisol metabolites concentration in stallions? Type Conference Article
  Year 2015 Publication Proceedings of the 3. International Equine Science Meeting Abbreviated Journal Proc. 3. Int. Equine. Sci. Mtg  
  Volume Issue Pages  
  Keywords housing system, stallions, social interaction, stress, faecal cortisol metabolites  
  Abstract In order to improve the housing conditions of stallions in individual boxes by offering a possibility to have more social contact, the Swiss national stud farm tested a new box system for horses, allowing increased physical contact with the neighbouring stallion. The aim of this part of the study was to investigate whether this type of housing system (named “social box”) potentially induces a change in stress reactions in stallions compared to conventional boxes. Therefore faecal cortisol metabolite (FCM) concentration was measured as a non-invasive parameter to assess endocrine responses related to this new environment.

Four groups each consisting of eight adult Freiberger breeding stallions were included in the test design. Every stallion spent three weeks in a conventional box and in a social box respectively (cross-over design). The conventional box consisted of a separation wall with a lower opaque part and an upper part with vertical barriers (5 cm between barriers), allowing visual and olfactory contact but strongly limiting tactile contact. The separating wall of the social box consisted of two lateral sections, one part being opaque to the ceiling and the second part consisting of vertical barriers (30 cm between barriers), allowing the horse to have physical contact with its neighbour or to avoid it.

In horses, FCM concentration reflects an average level of circulating cortisol over a period of approximatively 24h. Faecal samples were collected the day following integration in social / conventional boxes, reflecting the potential stress induced by increased social interactions during the integration. In order to asses potential chronical stress, faeces samples were also collected in week one, two and three after the integration into the social / conventional box (in total: 4 samples per horse and housing system). The samples were immediately stored at -20°C until they were analysed. The samples were not analysed in the laboratory until the end of the experiment, therefore the duration of conservation in the freezer varied from 40 to 429 days.

A considerable percentage of data from groups 1 and 2 was below the detection limit (<0.8 ng/g) (Tab. 1). Thus the statistical analysis was conducted with the FCM concentration from groups 3 and 4 (n horses = 16) which contained no values below the detection limit.

Tab. 1: Details about FCM values and storage time for the 4 groups of stallions

Group Storage duration [d] Proportion of data below the detection limit (<0.8 ng/g) Mean [ng/g] Median [ng/g]

Group 1 384-429 55.6 % 2.2 0

Group 2 315-360 25.5 % 5.8 6.3

Group 3 41-79 0.0 % 8.7 8.0

Group 4 40-85 0.0 % 5.8 5.4

Despite the impressive social interactions observed between the stallions directly after being introduced into the social boxes, we did not find any differences in FCM concentration between the stallions being introduced into the conventional box and the social box on the day of integration (social box: n samples = 16, mean±SD: 6.9±4.7 ng/g; conventional box: n samples = 16, mean±SD: 9.0±11.2 ng/g; Wilcoxon signed rank test V = 70, p = 0.94).

Overall the samples taken during integration and in week one, two and three did not show evidence of changes in FCM concentration in either housing system over a longer period of time (social box: n samples = 64, mean±SD: 7.9±6.2 ng/g; conventional box: n samples = 64, mean±SD: 6.6±3.4 ng/g; Linear mixed model (LMM), p = 0.56).

Our results suggest that the possibility of having physical contact with a conspecific does not induce changes in FCM concentration in breeding stallions. The considerable percentage of values below the detection limit in groups 1 and 2 seemed to correlate with the increasing duration of storage before analysis. During the IESM Network Meeting 2015, we would like to discuss possible methodological issues and the possibilities to correctly integrate these low values in the statistical analysis.

  Title Cortisol, adrenocorticotropic hormone, serotonin, adrenaline and noradrenaline serum concentrations in relation to disease and stress in the horse Type Journal Article
  Year 2012 Publication Research in Veterinary Science Abbreviated Journal  
  Volume 93 Issue 1 Pages 103-107  
  Keywords Horse; Disease; Cortisol; Acth; Serotonin; Catecholamines; Stress  
  Abstract No detailed comparative data are available on the hormonal parameters of horses suffering from a number of diseases. The aim of our study was to measure concentrations of cortisol, adrenocorticotropic hormone (ACTH), serotonin, adrenaline and noradrenaline in horses with various diseases and following surgery, to assess the response of the HPA axis and adrenal medulla. Blood samples were obtained from six groups of horses comprising a total of 119 animals as follows: laminitis, acute abdominal syndrome (AAS), castration surgery, acute diseases, chronic diseases and healthy controls. Serum hormonal concentrations were determined for each group for comparison. Statistically significant differences between all groups and controls were found for cortisol, ACTH (except for castration), serotonin and adrenaline concentrations but only in horses with laminitis and AAS for noradrenaline. No statistically significant differences were found between males and females. The largest changes in the pituitary–adrenal axis activity occurred mainly in acute diseases, laminitis and in the AAS group.

  Title Salivary IgA: a Possible Stress Marker In Dogs Type Abstract
  Year 1995 Publication Animal Welfare Abbreviated Journal  
  Volume 4 Issue 4 Pages 339-350  
  Keywords Animal Welfare; Behaviour; Cortisol; Dog; Salivary Iga (S-Iga); Stress; Well-Being  
  Abstract Stress in humans has been reported to be associated with a decrease in the salivary immunoglobulin A (s-IgA) levels enabling the possible use of s-IgA to assess stress. Prolonged stress, if reliably assessed in a non-invasive manner, may be used to assess animal welfare. This study analysed groups of dogs undergoing physical and temperamental training and s-IgA levels were measured by rocket immunoelectrophoresis in prospective samples. Behavioural assessment was carried out and cortisol levels in saliva were measured by ELISA. A significant negative correlation (P < 0.007) between the logarithmic cortisol concentrations and s-IgA levels in saliva was recorded. The behavioural assessment of the dogs agreed well with the biochemical markers. It is concluded that IgA levels in saliva may be a useful marker of dog well-being and that stress results in decreased s-IgA levels.

  Title Are cats (Felis catus) from multi-cat households more stressed? Evidence from assessment of fecal glucocorticoid metabolite analysis Type Journal Article
  Year 2013 Publication Physiology & Behavior Abbreviated Journal Physiol. Behav.  
  Volume 122 Issue Pages 72-75  
  Keywords Feline; Housing; Non-invasive; Enzyme immunoassay; Cortisol  
  Abstract Abstract Given the social and territorial features described in feral cats, it is commonly assumed that life in multi-cat households is stressful for domestic cats and suggested that cats kept as single pets are likely to have better welfare. On the other hand, it has been hypothesized that under high densities cats can organize themselves socially thus preventing stress when spatial dispersion is unavailable. This study was aimed at comparing the general arousal underpinning emotional distress in single housed cats and in cats from multi-cat households (2 and 3–4 cats) on the basis of fecal glucocorticoid metabolites (GCM) measured via enzyme immunoassay (EIA). GCM did not significantly vary as a function of living style (single, double or group-housing); highly stressed individuals were equally likely in the three groups. Young cats in multi-cat households had lower GCM, and overall cats that tolerate (as opposed to dislike) petting by the owners tended to have higher GCM levels. Other environmental aspects within cat houses (e.g. relationship with humans, resource availability) may play a more important role in day to day feline arousal levels than the number of cats per se.
