  Title Exploration of the hypothalamic-pituitary-adrenal function as a tool to evaluate animal welfare Type Journal Article
  Year 2007 Publication Physiology & Behavior Abbreviated Journal Physiol. Behav.  
  Volume 92 Issue 3 Pages 317-339  
  Keywords Stress; Animal welfare; HPA axis; Glucocorticoid hormones; Acth; Dexamethasone suppression test; Cattle; Pig; Fur animals; Mink; Fox; Poultry; Fish  
  Abstract Measuring HPA axis activity is the standard approach to the study of stress and welfare in farm animals. Although the reference technique is the use of blood plasma to measure glucocorticoid hormones (cortisol or corticosterone), several alternative methods such as the measurement of corticosteroids in saliva, urine or faeces have been developed to overcome the stress induced by blood sampling itself. In chronic stress situations, as is frequently the case in studies about farm animal welfare, hormonal secretions are usually unchanged but dynamic testing allows the demonstration of functional changes at several levels of the system, including the sensitization of the adrenal cortex to ACTH and the resistance of the axis to feedback inhibition by corticosteroids (dexamethasone suppression test). Beyond these procedural aspects, the main pitfall in the use of HPA axis activity is in the interpretation of experimental data. The large variability of the system has to be taken into consideration, since corticosteroid hormone secretion is usually pulsatile, follows diurnal and seasonal rhythms, is influenced by feed intake and environmental factors such as temperature and humidity, age and physiological state, just to cite the main sources of variation. The corresponding changes reflect the important role of glucocorticoid hormones in a number of basic physiological processes such as energy metabolism and central nervous system functioning. Furthermore, large differences have been found across species, breeds and individuals, which reflect the contribution of genetic factors and environmental influences, especially during development, in HPA axis functioning. Usually, these results will be integrated with data from behavioral observation, production and pathology records in a comprehensive approach of farm animal welfare.

  Title Interaction with horses (equus): Assessment with a circumplex based questionnaire Type Conference Article
  Year 2008 Publication IESM 2008 Abbreviated Journal  
  Volume Issue Pages  
  Keywords human-pet interaction, interpersonal theory, distress  
  Abstract According to Interpersonal Theory every interaction is motivated by efforts to achieve and maintain self-esteem and to avoid anxiety. People“s characteristic ways of accomplishing these ends are called interpersonal reflexes. Those interpersonal reflexes are evident in interaction with animals, since they are determined by the interpersonal traits of personality. We wanted to catch the typical interpersonal reflexes in between humans and horses compared to pet animals.

We used the self rating assessment instrument ”Inventory of Problematic Interactions with Animals" (IPI – Animals), which bases on a Interpersonal Circumplex Model (Human Animal Circumplex; HAC) and was constructed to catch specific dispositions of distress caused by animals using two dimensions (too dominant vrs too submissive and too warm versus too cold). Data of 233 male adolescents (93 of them actual pet owners, from that 12 horse owners) were collected.

We found that different pet preferences holds distinct locations in the HAC. Horse persons differ from dog and cat persons within the dimension dominance (dog: chi2(df126) =161.54 p= .018; cat: chi2(df126) =199.95 p= .045). Persons, who own a horse or would wish to own one, describe themselves as dominant, but warm interactors. They report that they want horses to notice them. They tend do too much for them and behave very effusively with them. On the other hand they feel that the animal takes too much advantage of the relationship.

  Title Is modified Forssell"s operation superior to cribbing collar in preventing crib-biting in horses? Type Conference Article
  Year 2008 Publication IESM 2008 Abbreviated Journal  
  Volume Issue Pages  
  Keywords stereotypic behaviour, heart-rate variability, stress, equine welfare  
  Abstract Crib-biting (wind-sucking) might be a coping response of the horses to the challenges of

uncontrolled environmental events. Prevention of this stereotypic behaviour evokes

physiological responses consistent with increased stress. Reducing the incidence of cribbiting,

however, is important in order to prevent undesirable physical and behavioural

consequences (tooth erosion, altered gut function, gastric inflammation/ulceration, colic, etc.).

Common treatment of crib-biting is the application of a cribbing collar, which limits the

flexion of the neck making this stereotypic movement uncomfortable and difficult. Another

method, the modified Forssell“s operation, is becoming more and more popular amongst the

horse owners. It is based on the removal of the muscles used in crib-biting (m.omohyoideus,

m.sternohyoideus, m.sternothyrohyoideus) and the ventral branches of the spinal accessory

nerves. Surveys on the success of this surgical procedure have revealed inconsistent results,

and, contrary to the cribbing collar, its effect on the stress level have not been studied either.

The aim of our study was to determine whether the modified Forssell”s procedure is superior

to the cribbing collar treatment.

Differences in stress management was tested by a crib-biting provoking test, in which

surgically treated horses, crib-biting horses, crib-biting horses with cribbing collar, and

normal horses (those showing no stereotypies), altogether 56 horses were compared. In this

test, a food bucket had been placed out of the reach of the animal, from which titbits were

given 3 times. Behaviour and heart rate variability (HRV) of the horses were recorded and

analysed throughout the test. Hypotheses were tested by linear mixed model.

According to our results, both prevention methods (collar or surgery) inhibited crib-biting

successfully though not totally. Regarding behaviour and heart rate variability, horses

prevented from crib-biting (by collar or surgery) differed significantly from crib-biting and

normal horses but not from each other.

Normal horses were usually trying to reach the food-bucket while present and were standing

still afterwards, whereas the other three groups had not really made efforts to reach the

bucket, spent less time with resting, and performed or tried crib-biting. During the stress-test,

normal and crib-biting horses had shown good stress-adaptation to the challenge since their

HRV, after an initial increase, returned to the basal value by the end. On the contrary, HRV of

the two prevented groups remained elevated and showed large oscillations throughout. They

had not found a successful coping behaviour either.

Our results suggest that since prevention may significantly increase distress, the treatment in

itself, without changing the motivation of the horse to perform the replacement behaviour – it

seems to be unsatisfactory and insufficient. After prevention the motivation of the horse to

perform crib-biting should be addressed. In addition, considering that prevention by collar and

surgery had not resulted in any significant behavioural or physiological differences, the

superiority of the modified Forssell"s procedure might be questioned. However, the surgery

might be recommended if treatment with collar is ineffective.

  Title Dominance in vertebrate broods and litters Type Journal Article
  Year 2006 Publication Quarterly Review of Biology Abbreviated Journal  
  Volume 81 Issue 1 Pages 3-32  
  Keywords Aggression; Assessment; Dominance; Individual recognition; Sibling conflict; Trained losing  
  Abstract Drawing on the concepts and theory of dominance in adult vertebrates, this article categorizes the relationships of dominance between infant siblings, identifies the behavioral mechanisms that give rise to those relationships, and proposes a model to explain their evolution. Dominance relationships in avian broods can be classified according to the agonistic roles of dominants and subordinates as “aggression-submission,” “aggression-resistance, ” “aggression-aggression,” “aggression-avoidance,” “rotating dominance,” and “flock dominance.” These relationships differ mainly in the submissiveness/pugnacity of subordinates, which is pivotal, and in the specificity/generality of the learning processes that underlie them. As in the dominance hierarchies of adult vertebrates, agonistic roles are engendered and maintained by several mechanisms, including differential fighting ability, assessment, trained winning and losing (especially in altricial species), learned individual relationships (especially in precocial species), site-specific learning, and probably group-level effects. An evolutionary framework in which the species-typical dominance relationship is determined by feeding mode, confinement, cost of subordination, and capacity for individual recognition, can be extended to mammalian litters and account for the aggression-submission and aggression-resistance observed in distinct populations of spotted hyenas and the “site-specific dominance” (teat ownership) of some pigs, felids, and hyraxes. Little is known about agonism in the litters of other mammals or broods of poikilotherms, but some species of fish and crocodilians have the potential for dominance among broodmates.

  Title The effects of predator odors in mammalian prey species: A review of field and laboratory studies Type Journal Article
  Year 2005 Publication Neuroscience and Biobehavioral Reviews Abbreviated Journal  
  Volume 29 Issue 8 Pages 1123-1144  
  Keywords Behavioral suppression; Defensive behavior; Endocrine effects; Neural effects; Predator odor; Small mammals  
  Abstract Prey species show specific adaptations that allow recognition, avoidance and defense against predators. For many mammalian species this includes sensitivity towards predator-derived odors. The typical sources of such odors include predator skin and fur, urine, feces and anal gland secretions. Avoidance of predator odors has been observed in many mammalian prey species including rats, mice, voles, deer, rabbits, gophers, hedgehogs, possums and sheep. Field and laboratory studies show that predator odors have distinctive behavioral effects which include (1) inhibition of activity, (2) suppression of non-defensive behaviors such as foraging, feeding and grooming, and (3) shifts to habitats or secure locations where such odors are not present. The repellent effect of predator odors in the field may sometimes be of practical use in the protection of crops and natural resources, although not all attempts at this have been successful. The failure of some studies to obtain repellent effects with predator odors may relate to (1) mismatches between the predator odors and prey species employed, (2) strain and individual differences in sensitivity to predator odors, and (3) the use of predator odors that have low efficacy. In this regard, a small number of recent studies have suggested that skin and fur-derived predator odors may have a more profound lasting effect on prey species than those derived from urine or feces. Predator odors can have powerful effects on the endocrine system including a suppression of testosterone and increased levels of stress hormones such as corticosterone and ACTH. Inhibitory effects of predator odors on reproductive behavior have been demonstrated, and these are particularly prevalent in female rodent species. Pregnant female rodents exposed to predator odors may give birth to smaller litters while exposure to predator odors during early life can hinder normal development. Recent research is starting to uncover the neural circuitry activated by predator odors, leading to hypotheses about how such activation leads to observable effects on reproduction, foraging and feeding. © 2005 Elsevier Ltd.

  Title Of mice and men – and lopsided birds Type Journal Article
  Year 2008 Publication Cortex Abbreviated Journal  
  Volume 44 Issue 1 Pages 3-7  
  Keywords Cerebral asymmetry; Handedness; Evolution; Laterality  
  Abstract The article by Zucca and Sovrano (2008, this issue) represents part of a new wave of studies of lateralization in nonhuman species. This work is often in conflict with earlier studies of human cerebral asymmetry and handedness, and the associated claim that these asymmetries are uniquely human, and perhaps even a result of the “speciation event” that led to modern humans. It is now apparent that there are close parallels between human and nonhuman asymmetries, suggesting that they have ancient roots. I argue that asymmetries must be seen in the context of a bilaterally symmetrical body plan, and that there is a balance to be struck between the adaptive advantages of symmetry and asymmetry. In human evolution, systematic asymmetries were incorporated into activities that probably are unique to our species, but the precursors of these asymmetries are increasingly evident in other species, including frogs, fish, birds, and mammals – especially primates.

  Title Cerebral mechanisms for understanding emotional prosody in speech Type Journal Article
  Year 2006 Publication Brain and Language Abbreviated Journal  
  Volume 96 Issue 2 Pages 221-234  
  Keywords Emotion; Prosody; Speech; Laterality; Brain-damaged; Patient study; Sentence processing; Social cognitive neuroscience  
  Abstract Hemispheric contributions to the processing of emotional speech prosody were investigated by comparing adults with a focal lesion involving the right (n = 9) or left (n = 11) hemisphere and adults without brain damage (n = 12). Participants listened to semantically anomalous utterances in three conditions (discrimination, identification, and rating) which assessed their recognition of five prosodic emotions under the influence of different task- and response-selection demands. Findings revealed that right- and left-hemispheric lesions were associated with impaired comprehension of prosody, although possibly for distinct reasons: right-hemisphere compromise produced a more pervasive insensitivity to emotive features of prosodic stimuli, whereas left-hemisphere damage yielded greater difficulties interpreting prosodic representations as a code embedded with language content.

  Title Right hemispheric dominance in processing of unconscious negative emotion Type Journal Article
  Year 2006 Publication Brain and Cognition Abbreviated Journal  
  Volume 62 Issue 3 Pages 261-266  
  Keywords Right hemispheric dominance; Unconscious negative emotion; Subliminal affective priming; Emotional facial expressions  
  Abstract Right hemispheric dominance in unconscious emotional processing has been suggested, but remains controversial. This issue was investigated using the subliminal affective priming paradigm combined with unilateral visual presentation in 40 normal subjects. In either left or right visual fields, angry facial expressions, happy facial expressions, or plain gray images were briefly presented as negative, positive, and control primes, followed by a mosaic mask. Then nonsense target ideographs were presented, and the subjects evaluated their partiality toward the targets. When the stimuli were presented in the left, but not the right, visual fields, the negative primes reduced the subjects' liking for the targets, relative to the case of the positive or control primes. These results provided behavioral evidence supporting the hypothesis that the right hemisphere is dominant for unconscious negative emotional processing.

  Title Animal Communication: Parent-Offspring Type Book Chapter
  Year 2006 Publication Encyclopedia of Language & Linguistics Abbreviated Journal  
  Volume Issue Pages 284-288  
  Keywords Begging Strategies; Communication; Competition; Feeding Strategies; Fitness; Parental Care; Parent-Offspring Conflict; Recognition; Sibling Conflict  
  Abstract Parent-offspring communication has evolved under strong selection to guarantee that the valuable resource of parental care is expended efficiently on raising offspring. To ensure allocation of parental care to their own offspring, individual recognition becomes established in higher vertebrates when the young become mobile at a time when a nest site can no longer provide a safe cue to recognition. Such recognition needs to be established by rapid, sometimes imprinting-like, processes in animals producing precocial offspring. In parents, offering strategies that stimulate feeding and entice offspring to approach the right site have evolved. Such parental signals can be olfactory, acoustic, or visual. In offspring, begging strategies involve shuffling for the best place to obtain food – be this the most productive teat or the best position in the nest. This involves signals that make the offspring particularly obvious to the parent. Parents often feed young according to their signaling intensity but may also show favoritism for weaker offspring. Offspring signals also serve to communicate the continuing presence of the young and may thereby maintain brood-care behavior in parents. Internal processes in parents may end parental care irrespective of further signaling by offspring, thus ensuring that offspring cannot manipulate parents into providing substantially more care than is optimal for their own fitness.

  Title Is it possible to measure the welfare of the ridden horse? Type Manuscript
  Year 2008 Publication Abbreviated Journal  
  Volume Issue Pages  
  Keywords horse, welfare, training, learning, measure, assess  
  Abstract Since the time of domestication, humans have trained horses for the purpose of serving man. Different training methods have been developed throughout the centuries; some were developed with consideration for the horse's welfare, while others disregarded welfare to a great extent. Most present day training is based upon making the horse perform a desired behaviour through dominance and subordination. Although cooperative training techniques have gained popularity, everyday training lacks the application of learning theory or neglects the horse's learning capacities and their species' specific behaviour. Thus, the horse's welfare may be jeopardised.

The aim with this review is to consider methods that allow an objective assessment of the welfare of horses undergoing training. The review gives a brief insight into the history of horse training and handling. It proceeds with an overview of the horse"s learning abilities which is argued to be of paramount importance for effective training. The review then describes a few selected training techniques that are used today, based on negative and positive reinforcement, and discusses parameters from which it could be possible to assess the welfare of the ridden horse. The work concludes with suggestion for future
