Title | Behavioural adaptation in the domestic horse: potential role of apparently abnormal responses including stereotypic behaviour | Type | Journal Article | ||
Year | 2005 | Publication | Livestock Production Science | Abbreviated Journal | Livest. Prod. Sci. |
Volume | 92 | Issue | 2 | Pages | 177-182 |
Keywords | Behavioural adaptation; Horse; Stereotypic behaviour | ||||
Abstract | Classically, biologists have considered adaptation of behavioural characteristics in terms of long-term functional benefits to the individual, such as survival or reproductive fitness. In captive species, including the domestic horse, this level of explanation is limited, as for the most part, horses are housed in conditions that differ markedly from those in which they evolved. In addition, an individual horse's reproductive fitness is largely determined by man rather than its own behavioural strategies. Perhaps for reasons of this kind, explanations of behavioural adaptation to environmental challenges by domestic animals, including the capacity to learn new responses to these challenges, tend to concentrate on the proximate causes of behaviour. However, understanding the original function of these adaptive responses can help us explain why animals perform apparently novel or functionless activities in certain housing conditions and may help us to appreciate what the animal welfare implications might be. This paper reviews the behavioural adaptation of the domestic horse to captivity and discusses how apparently abnormal behaviour may not only provide a useful practical indicator of specific environmental deficiencies but may also serve the animal as an adaptive response to these deficiencies in an “abnormal” environment. | ||||

Title | Species-specific differences and similarities in the behavior of hand-raised dog and wolf pups in social situations with humans | Type | Journal Article | ||

Abstract | In order to reveal early species-specific differences, we observed the behavior of dog puppies (n = 11) and wolf pups (n = 13) hand raised and intensively socialized in an identical way. The pups were studied in two object-preference tests at age 3, 4, and 5 weeks. After a short isolation, we observed the subjects' behavior in the presence of a pair of objects, one was always the subject's human foster parent (caregiver) and the other was varied; nursing bottle (3 weeks), unfamiliar adult dog (3 and 5 weeks), unfamiliar experimenter (4 and 5 weeks), and familiar conspecific age mate (4 weeks). Dogs and wolves did not differ in their general activity level during the tests. Wolf pups showed preference for the proximity of the caregiver in two of the tests; Bottle-Caregiver at the age of 3 weeks and Experimenter-Caregiver at the age of 5 weeks, while dogs showed preference to the caregiver in three tests; conspecific Pup-Caregiver and Experimenter-Caregiver at the age of 4 weeks and dog-caregiver at the age of 5. Compared to wolves, dogs tended to display more communicative signals that could potentially facilitate social interactions, such as distress vocalization, tail wagging, and gazing at the humans' face. In contrast to dog puppies, wolf pups showed aggressive behavior toward a familiar experimenter and also seemed to be more prone to avoidance. Our results demonstrate that already at this early age - despite unprecedented intensity of socialization and the comparable social (human) environment during early development - there are specific behavioral differences between wolves and dogs mostly with regard to their interactions with humans. © 2005 Wiley Periodicals, Inc.

Abstract | The social brain hypothesis proposes that large neocortex size in Homonoids evolved to cope with the increasing demands of complex group living and greater numbers of interindividual relationships. Group living requires that individuals communicate effectively about environmental and internal events. Recent data have highlighted the complexity of chimpanzee communication, including graded facial expressions and referential vocalizations. Among Hominoids, elaborate facial communication is accompanied by specializations in brain areas controlling facial movement. Finally, the evolution of empathy, or emotional awareness, might have a neural basis in specialized cells in the neocortex, that is, spindle cells that have been associated with self-conscious emotions, and mirror neurons that have recently been shown to activate in response to communicative facial gestures. | ||||

Title | Assessment of equine temperament questionnaire by comparing factor structure between two separate surveys | Type | Journal Article | ||

Abstract | To establish a method for assessing equine temperament by use of a questionnaire, we carried out two surveys. The subject animals were all thoroughbreds maintained at the same farm. Respondents were the primary caretaker and two colleagues working with each horse. Factor analysis was performed on the responses to each survey. In both surveys, five factors were extracted and four of them were common between the two surveys. The common factors were [`]Anxiety', [`]Trainability', [`]Affability', and [`]Gate entrance'. There were sufficient internal consistencies in responses about [`]Anxiety', [`]Trainability', and [`]Affability' in the two surveys to indicate the validity of this questionnaire in evaluating these factors in equine temperament. | ||||

Title | Untersuchungen zum Einfluss der Fütterung auf den Säure-Basen-Haushalt bei Ponys | Type | Manuscript | ||
Year | 2005 | Publication | Abbreviated Journal | ||
Volume | Issue | Pages | |||
Keywords | |||||
Abstract | In der praktischen Pferdefütterung kommen regelmäßig Substanzen zum Einsatz, die einen erheblichen Einfluss auf den Säure-Basen-Haushalt ausüben. Andererseits können Manipulationen des Säure-Basen-Haushaltes in der Diätetik erwünscht sein, z.B. bei Harnsteinen oder hyperkaliämischer periodischer Paralyse. Verschiebungen im Säure- Basen-Gleichgewicht treten – unabhängig von der Fütterung – außerdem bei starker körperlicher Aktivität auf, eine eventuelle Prophylaxe durch die Ernährung wird ebenfalls diskutiert. Der Einfluss der Fütterung auf den Säure-Basen-Haushalt ist beim Pferd bisher nur wenig und nicht systematisch untersucht, während sich viele Arbeiten mit dem Effekt körperlicher Belastung beschäftigen. Analogieschlüsse zu anderen Spezies müssen äußerst vorsichtig betrachtet werden, da die Absorption von am Säure- Basen-Haushalt beteiligten Substanzen beim Pferd Unterschiede zu anderen Spezies aufweist (Meyer, 1982). In der vorliegenden Untersuchung sollte daher der Effekt von verschiedenen Chloriden (Natriumchlorid, Kalziumchlorid, Ammoniumchlorid) auf den Säure-Basen-Haushalt bei Ponys geprüft werden. In den ersten Versuchsdurchgängen wurden für Kleinpferde im Erhaltungsstoffwechsel für diesen Zweck Rationen mit sehr hohen Heuanteilen verwendet. Trotz hoher Dosen des bei verschiedenen Spezies stark säuernden Ammoniumchlorids traten bei den Ponys nur relativ kleine Effekte auf. Bei der weiteren Durchsicht des Schrifttums fiel auf, dass Einzelbeobachtungen zu stark säuernden Effekten nur bei Rationen mit hohem Anteil an Kraftfutter und geringem Anteil an Rauhfutter auftraten. Daher wurde der Effekt von Ammoniumchlorid auf einer stark kraftfutterhaltigen Ration nochmals überprüft. |

Title | Effect of oestrous-cycle stage on the response of mares in a novel object test and isolation test | Type | Journal Article | ||

Abstract | In various species, sex, hormonal treatments and oestrous-cycle stage have been shown to affect the animal's response in behavioural tests. Few such studies have been performed in the horse. The main aim of the present study was to investigate whether oestrous-cycle stage affects mares' response to a novel object test and isolation test and, in part, to study whether mares, assumed to suffer from oestrous-related behavioural problems, respond differently in these tests when compared with controls. Twelve mares were tested twice, in oestrus and dioestrus, in a crossover design. Seven behavioural and two heart rate variables were measured for the novel object test and two heart rate variables for the isolation test. Oestrous-cycle stage and whether a mare was classified as a 'problem' mare did not affect the mare's response. However, test order, i.e. the cycle stage a mare was tested in first, affected its reaction. This effect could partly be explained by significant differences between test occasions 1 and 2 in three behavioural variables and one heart rate variable (p < 0.05) in the novel object test. The mares explored the novel object more and had a higher mean heart rate in the first test. Exploring the novel object more could largely be attributed to those mares tested in dioestrus first, perhaps indicating that the mares in oestrus were less receptive to the novel object. The reason for the differences between test occasions could be an effect of learning or habituation. | ||||

Title | Behavioural asymmetry is involved in regulation of autonomic processes: Left side presentation of food improves reproduction and lactation in cows | Type | Journal Article | ||
Year | 2005 | Publication | Behavioural Brain Research | Abbreviated Journal | Behav. Brain. Res. |

Keywords | Behavioural asymmetry; Somatic functions; Reproduction; Lactation | ||||
Abstract | It is known that the right and left brain hemispheres differ in their ability to regulate autonomic processes in the organism. Direct unilateral stimulation of the brain provokes side-dependent endocrine, immune and other visceral reactions. Since brain hemispheres are mainly involved in the regulation of muscles and sensory organs on the contra lateral side of the body the activation of behavioural asymmetry stimulates the contra lateral half of the brain. The important theoretical and practical question of whether autonomic processes can be regulated via the behavioural asymmetry route remains unexplored. In this study, we report that the chronic presentation of an emotionally important stimulus--food--from the left side, improves reproductive performance in animals in a broad range of feeding conditions. The unilateral presentation of food can also influence lactation, but in this case the side-dependent effects are different under varying feeding conditions. This finding opens a simple practical approach to influence basic somatic functions in the organism. | ||||
