  Title Foal behaviour in a loose housing/paddock environment during winter Type Journal Article
  Year 2005 Publication Applied Animal Behaviour Science Abbreviated Journal Appl. Anim. Behav. Sci.  
  Volume 91 Issue 3-4 Pages 277-288  
  Keywords Foal behaviour; Horse; Loose house; Time budget; Weather  
  Abstract The aim of this study was to establish some basic facts about weanling horse (Equus caballus) behaviour in a loose housing/paddock environment during winter. The behaviour of 10 foals (seven American Standardbred and three Finnish cold-blooded foals) was observed in a cold loose housing/paddock environment from December 2002 to March 2003. The time budget, circadian rhythm and effect of weather conditions on behaviour were examined. The foals were observed for a total of 23 24-h periods by video recording. The method used was instantaneous sampling (), where the locations of foals were noted at every 15 min along with the behaviour performed at that time. Temperature, humidity and wind speed were recorded three times a day. The foals spent 43.2 +/- 6.6% of the time in the sleeping hall (an insulated building with a deep-litter bed), 51.4 +/- 5.8% in the open paddock and 5.2 +/- 2.7% in the shelter (a two-sided, roofed entrance shelter in front of the sleeping hall). The time spent outdoors was greatest between the hours of 08:00 and 20:00, but the foals spent some time outdoors also at night. They spent most of the day eating hay (27.6 +/- 3.0%) (offered ad libitum), standing (25.5 +/- 2.8%) and resting (32.1 +/- 2.4%). The proportion of locomotive behaviour patterns was 5% of the observations. The foals in this study were able to perform species-specific behaviour patterns (resting, eating, being active) and to follow the natural circadian rhythm of these patterns. The behaviour of the foals did not change much as the temperature dropped from 0 to -20 [degree sign]C. The time spent in the sleeping hall did not increase greatly, nor the time spent eating, resting or lying close to each other (huddling). On the basis of their behaviour, the weanling horses did not seem to suffer from the cold environment.

  Title The effects of diet and weaning method on the behaviour of young horses Type Journal Article
  Year 2005 Publication Applied Animal Behaviour Science Abbreviated Journal Appl. Anim. Behav. Sci.  
  Volume 95 Issue 3-4 Pages 205-221  
  Keywords Horse; Diet; Weaning; Temperament test  
  Abstract The effects of diet on horse behaviour have not previously been quantified in detail. In this study, we examined the behaviour of 17 foals from the age of 2 to 40 weeks. Each foal received either a starch and sugar (SS) diet or a fat and fibre (FF) diet. The two diets contained similar digestible energy, crude protein and micronutrients, but differed in the fat and non-structural carbohydrate balance. The baseline behaviour of the foals was observed every 2 weeks by focal animal sampling. Additional behavioural observations were conducted when the foals were weaned by one of two methods. Approximately 2 months after weaning, the temperament and tractability of the young horses was assessed using standardised tests. Responses to a novel object, to a novel person, and during a handling test were observed and quantified. Horses grew well on both diets with no apparent effects of diet on growth rate or baseline behaviour. Immediately after weaning, horses receiving the FF diet cantered less frequently (F = 5.10; p < 0.05), for a shorter duration (F = 7.23; p < 0.05) and appeared to be more settled. Foals that were barn-weaned appeared more stressed than foals that were paddock-weaned. In the temperament tests, horses receiving the FF diet spent significantly more time investigating (F = 6.78; p < 0.05), and less time looking at (F = 7.93; p < 0.05), the novel object than horses receiving the SS diet. They also spent less time walking away from the novel person (F = 5.16; p < 0.05) and their time taken to complete the handling test was significantly lower (F = 8.72; p = 0.01). Overall, the horses that received the FF diet appeared less distressed immediately after weaning and seemed calmer and more inquisitive during a range of temperament tests.

  Title Selection and acceptance of flavours in concentrate diets for stabled horses Type Journal Article
  Year 2005 Publication Applied Animal Behaviour Science Abbreviated Journal Appl. Anim. Behav. Sci.  
  Volume 95 Issue 3-4 Pages 223-232  
  Keywords Horse; Flavour; Diet; Selection; Acceptance  
  Abstract Like most large grazing herbivores, horses select their food based on visual cues, odour, taste, texture, availability and variety. There is relatively little published information about the role of flavour in diet selection by domestic horses in comparison with other domestic and companion animals. However, previous trials investigating effects of diet flavour in stabled horses indicated significant effects on foraging behaviour and selection. In this series of three trials we aimed to determine relative acceptance by presenting flavour preference tests to eight horses. Horses were stabled and fed hay ad lib on trial data collection days plus a standard unflavoured concentrate ration at 7:30 a.m. In Trial 1, 15 flavours were separately presented in standard 100 g cereal by-product meals and the trial was replicated. Quantity consumed, time of completion, partial rejection or refusal were recorded. Order of presentation was determined by a Latin Square design. Trial data were collected on five sampling days, separated by a minimum of 1 day. Horses were presented with six flavoured meals daily; minimum 1 h between the meals. Twelve flavours were universally accepted and of these the eight flavours with fastest mean consumption times (banana, carrot, cherry, cumin, fenugreek, oregano, peppermint and rosemary) were presented in paired preference tests in Trial 2. In Trial 2, all paired combinations of the eight flavours were presented, in two tests per day at noon and 4 p.m. Presentations of the same flavour were separated by at least 1 day. Paired presentations were in 300 g cereal by-product. Presentations were terminated when approximately half of the total amount presented had been consumed. Flavour preferences were expressed as a ratio from 0 (rejection) to 1 (exclusive consumption). Paired flavour preferences produced the following rank order: fenugreek, banana, cherry, rosemary, cumin, carrot, peppermint, oregano. In Trial 3, relative consumption times of mineral pellets flavoured with fenugreek and banana were significantly reduced in comparison with unflavoured pellets. In these short-term trials, flavour had significant effects on diet acceptance, selection and consumption times.

  Title Exercise-induced physiological adjustments to stressful conditions in sports horses Type Journal Article
  Year 2005 Publication Livestock Production Science Abbreviated Journal Adaptability of sport horses to stressful conditions  
  Volume 92 Issue 2 Pages 101-111  
  Keywords Horse; Exercise; Stress  
  Abstract Among athletic/sports animals, the horse has a unique ability to increase its oxygen uptake by a factor of 60 during heavy exercise. This is achieved by physiological adaptations of all the links in the oxygen chain. Ventilation is increased by a factor of 30. Since the horse is a compulsory nasal breather, this hyperpnea necessitates high transmural pressure changes, which may be responsible for the dynamic collapse of the airways. Blood flow is increased by a factor of 10. Since the left ventricle is not very compliant, this increase necessitates a high filling pressure in the pulmonary circulation, which may induce capillary stress failure and exercise-induced pulmonary haemorrhage. Lastly, oxygen transport is improved by splenic contraction which increases haemoglobinemia by 50%. Sports horses frequently suffer from several problems, which are related either to endogenous or exogenous stresses experienced during their career. These stresses, caused by the use of the horse as a competition animal, may lead to several medical problems. At a systemic level, endogenous stresses include hyperkaliemia, lactacidemia, and hyperthermia; oxidative stress may induce problems at a general, and/or a pulmonary level. External factors, e.g. poor quality of inspired air, transport, hot and humid ambient conditions, and microbiological agents, may also induce abnormal body attacks, and lead to health problems.

  Title Risk factors for cross-country horse falls at one-day events and at two-/three-day events Type Journal Article
  Year 2005 Publication The Veterinary Journal Abbreviated Journal  
  Volume 170 Issue 3 Pages 318-324  
  Keywords Horse; Eventing; Fall; Cross-country; Risk  
  Abstract The cross-country phase of eventing competitions has been associated with injuries and fatalities to horses and riders. A case-control study was carried out to identify variables that were associated with increased or decreased risk of a horse fall on the cross-country phase at event competitions. After initial analysis, the dataset was split according to the categories of one-day events as compared to two- or three-day events to establish whether significant risk factors varied between the different types of eventing competitions. Data were collected for 121 cases (horse falls) at one-day events, 59 cases at two- or three-day events and for their 540 matched controls. The data were analysed using conditional logistic regression. The variables of no previous refusals on the course, fences with a landing in water and the combined variable of the angle and the spread of the fence were significantly associated with the risk of a horse fall in both datasets. Additional risk factors for one-day event falls were: fences requiring a take-off from water, a drop landing, the rider's knowledge of their position before the cross-country phase and if the rider received cross-country tuition. Three-day event risk factors in the multivariable model included: the camber of the fence and participation in non-equestrian sports by the rider. This study identified variables that were significantly associated with an increase or a decrease in the risk of a horse fall during the cross-country phase of different types of eventing competitions. Some of these variables are modifiable and the results of this study have been reported to the governing body of the sport of eventing in the UK so that possible interventions might be considered.

  Title Effects of Orientation, Intermittent Rest and Vehicle Cleaning During Transport on Development of Transport-related Respiratory Disease in Horses Type Journal Article
  Year 2005 Publication Journal of Comparative Pathology Abbreviated Journal  
  Volume 132 Issue 2-3 Pages 153-168  
  Keywords horse; respiratory disease; transit fever; transit stress  
  Abstract Summary The effects of various factors on the inflammatory and stress response in horses during transportation were examined in Experiments 1 and 2, carried out in April and August, respectively. In Experiment 1, three groups (G1-G3) of four Thoroughbreds were used, and in Experiment 2, two groups (G4, G5). G1 animals were loaded into lorries with their heads facing forwards (FF) and given periods of short rest (SR) (30 min for every 4 h driven). G2 horses were loaded facing rearwards (FR) and given SR. G3 horses were FF and given periods of long rest (LR) (2 h rest for every 4 h driven). G4 horses were transported FF with hay suspended in front of them and no cleaning of faeces or urine during rest stops. G5 horses were FF and given pellets instead of hay, and the lorry was cleaned and washed at each rest stop. G4 and G5 horses were rested for 1 h after every 5 h of driving. All groups were driven a distance of 1500 km, and the total journey time was 37 h for G1 and G2, 49 h for G3, and 40 h for G4 and G5. In Experiment 1, indicators of inflammatory and stress responses tended to be highest in G1, intermediate in G2 and lowest in G3. In Experiment 2 they tended to be higher in G4 than in G5. The results suggested that increasing the rest time and cleaning the interior of the vehicle during rest stops reduced transportation stress and respiratory insults, factors that may lead to respiratory disease.

  Title The effect of kinesthetic imagery on the sport confidence of flat-race horse jockeys Type Journal Article
  Year 2005 Publication Psychology of Sport and Exercise Abbreviated Journal  
  Volume 6 Issue 4 Pages 443-459  
  Keywords Vmiq; Miq; Multiple-baseline design; Itsacorr  
  Abstract Objectives The primary objective was to examine the efficacy of a kinesthetic imagery intervention on the sport confidence of three professional flat-race horse jockeys, with the secondary objective of examining the relationship between performance and sport confidence.Design A multiple-baseline across participants research design was employed.Methods The State Sport Confidence Inventory [SSCI; Vealey, R.S. (1986). Conceptualization of sport confidence and competitive orientation: Preliminary investigation and instrument development. Journal of Sport Psychology, 8, 221-246.] was administered twice weekly, prior to a total of 23, 25, and 27 races for participants 1, 2, and 3, respectively. In addition, performance data were collected on each SSCI data collection day. The kinesthetic imagery intervention consisted of six kinesthetic imagery sessions, twice weekly during a 3-week period. The intervention was introduced after race 7, 9, and 11 for participants 1, 2, and 3, respectively. Approximately, 1 week after the end of the data collection, participants completed a postexperimental questionnaire.Results ITSACORR [Crosbie, J. (1993). Interrupted time-series analysis with brief single-subject data. Journal of Consulting and Clinical Psychology, 6, 966-974.] was employed to analyze the sport confidence data. The results of ITSACORR along with visual inspection, demonstrated a significant increase in sport confidence for participants 1 and 3, and a non-significant increase for participant 2. Kendall's tau b correlations failed to find a significant relationship between performance and confidence.Conclusions The results are discussed in terms of the value of kinesthetic imagery as a tool for athletes to practice and develop. Furthermore, this study demonstrates the ability of ITSACORR to provide a statistical analysis for serially dependent single-subject data.

  Title Cost of mobbing call to breeding pied flycatcher, Ficedula hypoleuca Type Journal Article
  Year 2005 Publication Behavioral Ecology Abbreviated Journal Behav. Ecol.  
  Volume 16 Issue Pages 37-40  
  Keywords ntipredator behavior, Ficedula hypoleuca, mobbing calls, mobbing costs, pied flycatcher.  
  Abstract Mobbing signals advertise the location of a stalking predator to all prey in an area and recruit them into the inspection aggregation. Such behavior usually causes the predator to move to another area. However, mobbing calls could be eavesdropped by other predators. Because the predation cost of mobbing calls is poorly known, we investigated whether the vocalizations of the mobbing pied flycatcher, Ficedula hypoleuca, a small hole nesting passerine, increase the risk of nest predation. We used mobbing calls of pied flycatchers to examine if they could lure predators such as the marten, Martes martes. This predator usually hunts by night and may locate its mobbing prey while resting nearby during the day. Within each of 56 experimental plots, from the top of one nest-box we played back mobbing sounds of pied flycatchers, whereas blank tapes were played from the top of another nest-box. The trials with mobbing calls were carried out before sunset. We put pieces of recently abandoned nests of pied flycatchers and a quail, Coturnix coturnix, egg into each of the nest-boxes. Nest-boxes with playbacks of mobbing calls were depredated by martens significantly more than were nest-boxes with blank tapes. The results of the present study indicate that repeated conspicuous mobbing calls may carry a significant cost for birds during the breeding season.

  Title Pheromone reception in mammals Type Journal Article
  Year 2005 Publication Reviews of Physiology, Biochemistry and Pharmacology Abbreviated Journal  
  Volume 154 Issue Pages 1-35  
  Keywords  
  Abstract Pheromonal communication is the most convenient way to transfer information regarding gender and social status in animals of the same species with the holistic goal of sustaining reproduction. This type of information exchange is based on pheromones, molecules often chemically unrelated, that are contained in body fluids like urine, sweat, specialized exocrine glands, and mucous secretions of genitals. So profound is the relevance of pheromones over the evolutionary process that a specific peripheral organ devoted to their recognition, namely the vomeronasal organ of Jacobson, and a related central pathway arose in most vertebrate species. Although the vomeronasal system is well developed in reptiles and amphibians, most mammals strongly rely on pheromonal communication. Humans use pheromones too; evidence on the existence of a specialized organ for their detection, however, is very elusive indeed. In the present review, we will focus our attention on the behavioral, physiological, and molecular aspects of pheromone detection in mammals. We will discuss the responses to pheromonal stimulation in different animal species, emphasizing the complicacy of this type of communication. In the light of the most recent results, we will also discuss the complex organization of the transduction molecules that underlie pheromone detection and signal transmission from vomeronasal neurons to the higher centers of the brain. Communication is a primary feature of living organisms, allowing the coordination of different behavioral paradigms among individuals. Communication has evolved through a variety of different strategies, and each species refined its own preferred communication medium. From a phylogenetic point of view, the most widespread and ancient way of communication is through chemical signals named pheromones: it occurs in all taxa, from prokaryotes to eukaryotes. The release of specific pheromones into the environment is a sensitive and definite way to send messages to other members of the same species. Therefore, the action of an organism can alter the behavior of another organism, thereby increasing the fitness of either or both. Albeit slow in transmission and not easily modulated, pheromones can travel around objects in the dark and over long distances. In addition, they are emitted when necessary and their biosynthesis is usually economic. In essence, they represent the most efficient tool to refine the pattern of social behaviors and reproductive strategies. © Springer-Verlag 2005.
