| Abstract | Elevated urinary catecholamines and their metabolites are the only findings which confirm the presence of pheochromocytoma. This examination is of particular interest if carried out in urine produced after spontaneous hypertensive episodes. Pharmacologic tests when carried out under standard conditions have proven to be a reliable aid in cases of suspected pheochromocytoma. Roentgenographic studies, determination of local plasma catecholamine concentrations and blood volume control should be undertaken in these patients before surgical procedure. | ||||

| Abstract | An alleged male foal of a female mule, whose sire and grandparents were unknown, was identified for its pedigree. Parentage testing was conducted by comparing polymorphism of 12 microsatellite DNA sites and mitochondrial D-loop sequences of the male foal and the female mule. Both the sequence analysis of species-specific DNA fragments and a cytogenetic analysis were performed to identify the species of the foal and its parents. The results showed that the alleged female mule is actually a hinny, and the male foal, which possesses 62 chromosomes, qualifies as an offspring of the female hinny and a jack donkey. | ||||

| Abstract | Acquiring water is essential for all animals, but doing so is most challenging for desert-living animals. Recently Przewalski's horse has been reintroduced to the desert area in China where the last wild surviving member of the species was seen before it vanished from China in the1960s. Its reintroduction placed it within the range of a close evolutionary relative, the con-generic Khulan. Determining whether or not these two species experience competition and whether or not such competition was responsible for the extinction of Przewalski's horses in the wild over 50 years ago, requires identifying the fundamental and realized niches of both species. We remotely monitored the presence of both species at a variety of water points during the dry season in Kalamaili Nature Reserve, Xinjiang, China. Przewalski's horses drank twice per day mostly during daylight hours at low salinity water sources while Khulans drank mostly at night usually at high salinity water points or those far from human residences. Spatial and temporal differences in water use enables coexistence, but suggest that Przewalski's horses also restrict the actions of Khulan. Such differences in both the fundamental and realized niches were associated with differences in physiological tolerances for saline water and human activity as well as differences in aggression and dominance. | ||||

| Title | Presence/absence-sample matching by pigeons: divergent retention functions may result from the similarity of behavior during the absence sample and the retention interval | Type | Journal Article | ||

| Keywords | Analysis of Variance; Animals; *Behavior, Animal; *Choice Behavior; *Columbidae; *Conditioning, Operant; Cues | ||||
| Abstract | Divergent choose-absence retention functions typically found in pigeons following presence/absence-sample matching have been attributed to the development of a single-code/default coding strategy. However, such effects may result from adventitious differential responding to the samples. In Experiment 1, retention functions were divergent only when differential sample responding could serve as the basis for comparison choice. In Experiment 2, when pecking did not occur during the retention interval, a choose-absence bias was found, but when pecking occurred during the retention interval, a choose-presence bias resulted. In Experiment 3, positive transfer was found when a stimulus associated with the absence of pecking replaced the absence sample but not when a stimulus associated with pecking replaced the presence sample. Thus, presence/absence-sample matching may not encourage the development of a single-code/default coding strategy in pigeons. | ||||

| Title | Interval timing with gaps: gap ambiguity as an alternative to temporal decay | Type | Journal Article | ||
| Year | 2005 | Publication | Journal of experimental psychology. Animal behavior processes | Abbreviated Journal | J Exp Psychol Anim Behav Process |
| Volume | 31 | Issue | 4 | Pages | 484-486 |
| Keywords | Animals; Behavior, Animal; Discrimination (Psychology)/*physiology; Memory/*physiology; Rats; Time Perception/*physiology | ||||
| Abstract | C. V. Buhusi, D. Perera, and W. H. Meck (2005) proposed a hypothesis of timing in rats to account for the results of experiments that have used the peak procedure with gaps. According to this hypothesis, the introduction of a gap causes the animal's memory for the pregap interval to passively decay (subjectively shorten) in direct proportion to the duration and salience of the gap. Thus, animals should pause with short, nonsalient gaps but should reset their clock with longer, salient gaps. The present authors suggest that the ambiguity of the gap (i.e., the similarity between the gap and the intertrial interval in both appearance and relative duration) causes the animal to actively reset the clock and prevents adequate assessments of the fate of timed intervals prior to the gap. Furthermore, when the intertrial interval is discriminable from the gap, the evidence suggests that timed intervals prior to the gap are not lost but are retained in memory. | ||||

| Abstract | In 32 Offenlaufställen mit computergesteuerten Abrufstationen wurden die Aufenthaltsdauer und Besuchshäufigkeit sowie das Droh- und Meideverhalten von 439 Pferden im Füttererungsbereich erfasst. Je Betrieb erfolgten visuelle kontinuierliche Direktbeobachtungen nach dem Tortenstückverfahren (6 x 4 Stunden) für je einen 24-Stunden-Tag. Ziel war die Überprüfung der verschiedenen Bauausführungen der Abrufstationen unter dem Aspekt der Tiergerechtheit. Eine Einwegstation reduzierte signifikant die Anzahl an Auseinandersetzungen im Fütterungsbereich. Demgegenüber führten die für das fressende Pferd tiergerechten Varianten (Fressstand mit Eingangssperre und ohne Austreibehilfe) zu einer Erhöhung der Besuchshäufigkeit und Aufenthaltsdauer und somit auch zu einer erhöhten Anzahl an Drohgesten. Doch insgesamt betrachtet, kann die Anzahl an sozionegativen Interaktionen im Fütterungsbereich der Abrufstationen als relativ gering eingestuft werden. Da sich außerdem der Betrieb (Management, Fläche, Konzeption) als maßgeblicher Einflussfaktor auf die überprüften Parameter erwies, dürften die Unterschiede in der Bauausführung der derzeitigen Abrufstationen für Pferde eher von untergeordneter Bedeutung sein. [Duration of stay, frequency of visit, threatening gestures and behaviour of avoidance of 439 horses was observed at the feeding area of 32 run-out-sheds. The observation was based on the method of visual continuously direct watching after the pie chart system (6 x 4 hours) over a period of 24 hours. The observation should show which construction of the different automatic feeding systems corresponded best under the aspect of animal welfare. It was obvious that the one-way-station reduced significantly the number of conflicts in the feeding area, whereas those systems which are appropriate for the eating horses (feeding station with access barrier and without stimulation device by electric shock) led to a higher frequency of visits and duration of stay as well as to more threatening gestures. Considering altogether, the number of negative interactions in the feeding area of the feeding systems can be classified as comparatively unimportant. As it showed that the stable (management, stable area, conception) was of important influence on the surveyed parameters, the differences between the constructions of feeding stations for horses of present systems are probably of less meaning.] |

| Abstract | In der Offenstallhaltung von Pferden wird für die individuelle Fütterung der Fressstand, der eine art-typische synchrone Nahrungsaufnahme erlaubt, empfohlen (BMELV 2009). Seit einigen Jahren kommen jedoch vermehrt Abrufstationen für Kraft- und Raufutter zum Einsatz. Diese ermöglichen nur ein asynchrones Fressen, was das Risiko für Auseinandersetzungen im Fressbereich erhöht. In einer repräsentativen Studie an insgesamt 567 individuell unterschiedenen Pferden in 32 Offen-laufställen mit Abrufstationen und 10 Betrieben mit Fressständen wurden die Aufenthaltsdauer und Besuchshäufigkeit sowie das Droh- und Meideverhalten der Pferde im Fütterungsbereich und die Häu-figkeit von Blockaden erfasst, des Weiteren Herzfrequenz und Integumentverletzungen. Fazit war, dass es an den Abrufstationen doppelt so oft zu Auseinandersetzungen kam als an den Fressständen. Als Ursache hierfür konnte die starke Frequentierung der Automaten eruiert werden. Umso wichtiger ist somit die tiergerechte Ausführung der Abrufautomaten. In der Studie konnte nachgewiesen werden, dass Durchlaufstationen pferdegerechter sind als Rücklaufstationen. Als nicht tiergerecht wurden Stationen mit Strom führender Austreibehilfe.eingestuft. Die für das fressende Pferd als verhaltens-gerecht empfohlene Variante (Fressstand mit Eingangssperre und ohne Austreibehilfe) führte zu einer Erhöhung der Besuchshäufigkeit und Aufenthaltsdauer und somit auch zu einer erhöhten Anzahl an Drohgesten je Tier und Tag. Die Herzfrequenz lag im Wartebereich bei den meisten Pferden im physio-logischen Bereich (45,1 ± 12,42 Schläge/min), erhöhte sich jedoch in der Abrufstation um ca. 20 Schlä-ge/min. Einige Tiere zeigten möglicherweise stressbedingt auffallend hohe Herzfrequenzwerte ( 100 Schläge/min). Integumentverletzungen im Zusammenhang mit dem Fütterungssystem traten nicht auf. Das Flächengebot und die Konzeption der Offenstallanlage sowie das Management erwiesen sich als maßgebliche Einflussfaktoren auf alle überprüften Kriterien zur Tiergerechtheit. Um die Anzahl an Auseinandersetzungen im Fütterungsbereich von Abrufstationen zu mindern wird eine Reduzierung der Fütterungshäufigkeit von üblicherweise bis zu 24 Mahlzeiten auf nur 10 Mahlzeiten empfohlen, gemäß dem natürlichen Fressrhythmus von Pferden. Unabhängig vom Fütterungssystem traten die wenigsten Auseinandersetzungen auf, wenn die Pferde täglich etwa 1,5 kg Heu pro 100 kg Körpermasse erhielten bei zusätzlicher ad Libitum Fütterung von Stroh. Nach bisherigen Erkenntnissen ergeben sich nachfolgende Checkpoints für Abrufautomaten: Checkpunkte für Abrufstationen  Schutz des Pferdes durch Trennwände über die gesamte Körperlänge  Trennwände mit Sichtkontakt zu den anderen Pferden  Durchlaufstationen mit separatem Ein- und Ausgang  Eingangssperre für eine stressfreie Futteraufnahme  Ausgang mit Pendeltüre und Rücklaufsperre  Ausgang in einen anderen Funktionsbereich  Ausreichend Ausweichmöglichkeiten für rangniedere Tiere  Räumliche Trennung von Kraftfutter- und Heuautomaten  Maximal je 10 Kraft- und Grobfutterrationen je Tier und Tag  ≥ 1,5 kg Heu bzw. Heulage pro 100 kg Körpermasse je Pferd und Tag  Stroh zur freien Verfügung (Möglichkeit zum synchronen Fressen)  Individuelles Anlernen der Pferde am Automaten erforderlich |

| Abstract | The guidelines of the Federal Ministry of User Protection, Nutrition and Agriculture (BMVEL) regarding “horse keeping with respect to animal welfare” are from 1995 (BMELF, 1995). Therefore, they are not suitable for modern horse keeping. The Veterinary Association for Animal Welfare (TVT) held it to be necessary to rework the guide-lines in light of 1) many subsequent investigations concerning horse keeping, and 2) the species-specific needs of horses in practice. Each chapter of the BMELF (1995) guide-lines was revised such that the literature and practical experiences were updated. Several chapters (recumbency resting behaviour, fences, underground outdoor and in stables, litter) were added in the position paper of the TVT to reflect the increasing use of boxes with paddocks, loose housing systems with open yards, pasture and winter yards as housing conditions. Keeping horses outdoors permanently during winter is possible because horses have very good thermoregulatory capabilities so that they are able to adapt themselves to cold conditions. However, in light of animal welfare, the holding system must include adequate shelter (natural or artificial). Shelters should protect against wetness, heat, cold and wind, and must be sufficiently large and high, with a dry and clean underground. In keeping horses outdoors permanently, the paths to the feeding and watering areas and to the shelter must be dry. The food must also be protected against mould and soiling. Keeping horses permanently without adequate shelter or in deep marsh without any dry places is against the Animal Protection Act. | ||||

| Abstract | Gegenstand und Ziel: Überprüfung der Tiergerechtheit von Abrufstationen für Kraftfutter und Heu in der Gruppenhaltung von Pferden anhand ethologischer und physiologischer Parameter im Vergleich zu konventionellen Fressständen. Material und Methoden: Die Verhaltensbeobachtungen fanden in 11 bzw. 10 Offenlaufställen mit Abrufstationen bzw. Fressständen statt. 270 Pferde wurden individuell unterschieden. Untersuchungsparameter waren: Drohverhalten mit und ohne Verletzungsrisiko, Meideverhalten, Verdrängung aus dem Fressstand sowie Herzfrequenz und Integumentverletzungen. In jedem Betrieb erfolgten kontinuierliche Direktbeobachtungen für je einen 24-Stunden-Tag (Tortenstückverfahren). Ergebnisse: Im Wartebereich der Abrufautomaten traten signifikant mehr Drohgesten ohne bzw. mit Verletzungsgefahr je Pferd und Tag (8,6 bzw. 3,0) auf als im Wartebereich der Fressstände (3,4 bzw. 0,9). Demgegenüber konnten die Pferde in Abrufstationen (1,4 Drohgesten je Pferd und Tag) ungestörter fressen als in Fressständen (3,2 Drohgesten je Pferd und Tag). Insgesamt betrachtet ergab sich jedoch bei beiden Fütterungssystemen eine geringe Anzahl an sozionegativen Interaktionen im Bereich der Futtereinrichtungen. Die Herzfrequenz lag im Warteareal im Durchschnitt im physiologischen Bereich (44,59 ± 11,73 Schläge/min). Integumentverletzungen im Zusammenhang mit dem Fütterungssystem traten nicht auf. Der wichtigste Einflussfaktor auf die Untersuchungskriterien war der Betrieb (Fläche, Konzeption, Management). Schlussfolgerung: Unter dem Aspekt der Tiergerechtheit hinsichtlich des Stress- und Verletzungsrisikos durch soziale Interaktionen eignen sich bei ordnungsgemäßer Gruppenhaltung mit fachgerechtem Management sowohl Fressstände als auch Abrufstationen für Pferde im Offenlaufstall. [Objective: A comparison with regard to animal welfare of feeding stalls and automatic feeding systems for hay and concentrates in group housing systems for horses using parameters of ethology and physiology. Material and method: The observations of animal behaviour took place in 10 stables with feeding stalls and in 11 stables with automatic feeding systems. The field around the feeding systems was divided into three areas with comparable dimensions (waiting area, exit area and inside of the feeding system). 270 horses were individually observed. Parameters of research comprised: threatening behaviour with and without risk of injury, avoiding behaviour, ”chasing away from the feeding place”, as well as heart rate and injuries of the integument. Every group of horses was continuously observed for 24 hours. This observation took place on four different days and comprised six sessions, each of 4 hours. Results: In the waiting area of the automatic systems there were significantly more threatening gestures with and without risk of injuries for each horse and day (8.6 and 3.0, respectively) than in the waiting area of the feeding stalls. In contrast, the horses could eat more relaxed in the automatic systems (1.4 threatening gestures for each horse and day) than in the feeding stalls (3.2 threatening gestures for each horse and day). All together the number of negative interactions in the feeding area of both feeding systems was relatively low. The heart rate was within the physiological range (44,59 ± 11,73 beats/min) in the waiting area. There were no injuries of the integument in correlation with the feeding systems. The most important factor of the observation criteria was the individual group housing system with its different dimension, conception and management. Conclusion: Under the aspect of animal welfare both feeding systems are suitable for horses with respect to the risk of stress and injuries by social interactions and under the condition of proper group housing with professional management.] |
