Abstract |
Horses are often stabled in individual boxes, a method that does not meet their natural needs and may cause psychical and
musculoskeletal diseases. This problem is particularly evident in Iceland, where horses often spend the long winter periods in cramped
boxes. The aim of this study was to analyze the suitability of a group housing system in Iceland, but the results are also applicable to
horses of other regions. Eight Icelandic horses were observed in an active stable system, and their behavior and time budget were
recorded. Movement and lying behavior were studied with ALT (Activity, Lying, Temperature detection) pedometers. The effect of an
automatic concentrate feeding station (CFS) on the horses’ behavior was examined. In the first period of investigation, the horses
were fed concentrates manually, and in the second period, they were fed with the CFS. Additional behavioral observations and a
determination of social hierarchy occurred directly or by video surveillance. The physical condition of the horses was recorded by body
weight (BW) measurement and body condition scoring (BCS). The results showed a significant increase between the first and second
trial periods in both the activity (P,0.001) and the lying time (P50.003) of the horses with use of the CFS. However, there was no
significant change in BW during the first period without the CFS (P50.884) or during the second period with the CFS (P50.540).
The BCS of the horses was constant at a very good level during both trial periods, and the horses showed a low level of aggression, a
firm social hierarchy and behavioral synchronization. This study concludes that group housing according to the active stable principle is
a welfare-friendly option for keeping horses and is a suitable alternative to conventional individual boxes. |

Abstract |
Ziel der Untersuchung war es, herauszufinden, welche Auswirkungen eine Erhöhung der
Gruppengröße bei Jungpferden auf die Bewegungsaktivität, das Liege- und Sozialverhalten
und die Körperkondition hat. Hierfür wurden insgesamt 42 Pferde im Alter von ein
bis zwei Jahren in Laufstallhaltung in die Untersuchung einbezogen. Die Jungpferde aus
der Bewegungs- und Liegeverhaltensanalyse waren in zwei Kleingruppen (acht und
11 Tiere) und einer Großgruppe (23 Tiere) aufgestallt.
In der Bewegungsaktivität waren deutliche Unterschiede zu erkennen. Es ließ sich ein
positiver Einfluss einer höheren Tierzahl nachweisen, aber kein Einfluss des Alters. Beim
Ruheverhalten konnten höhere Liegezeiten und -frequenzen mit einer Zunahme der
Gruppengröße und eine Abnahme der Liegezeit mit zunehmendem Alter ermittelt werden.
Eine Störung des Liegeverhaltens durch Gruppengrößen, die nicht der natürlichen
Herdenstruktur des Pferdes entsprechen, wurde nicht nachgewiesen. Jedoch hatte die
Haltung der Jährlinge in der großen Gruppe einen Anstieg der repulsiven Verhaltensweisen
zur Konsequenz. Zudem zeigte die Bestimmung des Body Condition Scores
Unterschiede in der Körperkondition bei den Jährlingen der Groß- bzw. der Kleingruppe.
Einem Mangel an Bewegung, der für das Auftreten von Gliedmaßenerkrankungen und
Verhaltensstörungen verantwortlich gemacht wird, kann durch die Haltung von Jungpferden
in großen Gruppen entgegengewirkt werden.
[It is often discussed that the inactivity of horses causes diseases of their musculoskeletal system. Due to these problems the objective of the investigation was to quantify if the size of a group has an effect on the behaviour of young horses. Data from 42 horses in the age of one to two years have been involved in the investigation. The data of two small groups were compared with data of one big group with 23 horses. The movement and lying behaviour of 28 horses were measured with ALT pedometers. The social behaviour of 33 yearlings was documented by direct observation. The results show that the median of the movement time of horses in group A is 82 minutes per day. In group B this increases to a median of 101 and group C reaches the highest median of 149. In the case of lying time an increasing group size leads to a longer duration and a higher frequency of lying, whereas an increase in the age reduces the lying duration. International research studies have shown that keeping of horses in big group husbandry systems is not very common by the owners of horses. In contrast these investigations have shown that horse keeping in big groups has no negative influence on the social behaviour and the Body Condition Score of young horses.] |

Abstract |
In contrast to horses in pastures, it is thought that free-ranging horses do not perform latrine behaviour, i.e. a behavioural pattern whereby the animals graze and defecate in separate areas. However, few studies deal with this particular subject, reporting contrasting conclusions. We hypothesize that horses free-ranging in large heterogeneous areas do not perform latrine behaviour. Thus, we believe that grazing and elimination behaviour are spatially related: where horses graze, they will also defecate. Behavioural data were collected from Konik horses, Haflinger horses, Shetland ponies and donkeys, grazing in different nature reserves (54-80 ha). Data for the different equids were analyzed separately, as well as data for mares and stallions (Konik and donkey stallions only). We investigated the proportion of the number of defecations/urinations while grazing on the total number of defecations/urinations; furthermore, we searched for the sequence of behaviours representing latrine behaviour in the strict sense. Additionally, we analyzed the correlation between grazing behaviour and eliminative behaviour on both vegetation type level and patch level. All the female equids often continued grazing while defecating. During urination, grazing ceases in the majority of instances. Cases where a mare terminated grazing in a certain vegetation type and sward height to eliminate in another vegetation type or in another sward height within the same vegetation type were rarely observed. On the vegetation type level as well as on the patch level, there was a highly significant (P<0.001) positive correlation between grazing time and number of eliminations (or eliminating time). The high values of the correlation coefficients (in case of the defecation variables r ranges between 0.553 and 0.955; in case of the urination variables r ranges between 0.370 and 0.839) illustrate that the spatial distribution of the eliminative behaviour can be explained to a high degree by the spatial distribution of the grazing behaviour. Results in the case of the stallions are preliminary, but indicate the same pattern. Horses, free-ranging in large heterogeneous areas, do not perform latrine behaviour, but defecate where they graze. Possibly, animal density is of major importance to explain this behavioural difference with horses in pastures. We suggest that also spatial vegetation heterogeneity and plant productivity of the grazed area, as well as parasite status of the grazing animals could play a role. |

Abstract |
Frühere Untersuchungen haben gezeigt, dass die tägliche Bewegung für die Gesunderhaltung der Pferde notwendig ist. Inwieweit sich jedoch unterschiedliche Bewegungsangebote auf das Stress-und Bewegungsverhalten von Pferden in einer Gruppen-Auslaufhaltung auswirken und ob der Bewegungsbedarf der Pferde durch eine Auslaufhaltung ohne zusätzliche Bewegung gedeckt werden kann, ist der Literatur bisher nicht zu entnehmen. Daher sollte in der nachfolgend beschriebenen Untersuchung der Frage nachgegangen werden, welche Auswirkungen verschiedene Bewegungsangebote auf die Bewegungsaktivität von Pferden in Gruppen-Auslaufhaltungen haben und ob diese das Wohlbefinden der Tiere beeinflussen. Letzteres wurde durch Messung der Herzfrequenzvariabilität und Bestimmung von Cortisolmetaboliten im Pferdekot erfasst und die Bewegungsaktivität der Pferde wurde mit ALT-Pedometern bestimmt.
Verglichen wurden eine Einzel-und Gruppenhaltung mit jeweils angrenzendem Auslauf, aber ohne eine zusätzliche Bewegung der Pferde außerhalb des Stalls. In drei weiteren Varianten der Gruppenhaltung bekamen die Pferde täglichen Auslauf auf einer unbegrünten Koppel, auf einer Weide oder durch gezielte Bewegung in einer Führanlage. Die Bewegungsaktivität konnte durch die zusätzliche Bewegung in Form von Weide oder Führanlage signifikant gesteigert werden.
Ein zusätzliches Bewegungsangebot führte bei den Pferden zu einer Abnahme der Stressbelastung und sollte auch den Pferden ermöglicht werden, die in einer Gruppenhaltung gehalten werden, um ihre physische und psychische Gesundheit zu erhalten.
[Former studies confirm the necessity of daily movement for the health of a horse. But so far no description could be found in the literature how different movement offerings impact the stress and movement behaviour of horses in group husbandries with close-by discharge. The same holds true for the question whether a discharge husbandry system can meet the movement requirements of horses if there isn�t any additional movement possibility. The aim of the present study was to examine different movement offerings, their effects on the movement activities of horses in a group horse husbandry with close-by discharge and the impact of the movement on the wellbeing of the animals.
The heart rate variability and the concentration of the cortisol metabolites in the horse excrement were analyzed for detecting the wellbeing of the horses. Additionally ALT-Pedometers were used for determining the movement activity.
A single and a group husbandry system, each with closeby discharge, were compared when horses had no additional movement outside the stable. In three further variants the group husbandry was supplemented with daily time on a non-grassy pasture land, a pasture or in a horse walker. Pasture or horse walker increased movement activity significantly. Nevertheless an additional movement offering resulted in a lower stress load of the horses and should also be allowed to horses in group husbandry systems to ensure the horse�s physical and mental health.] |

Abstract |
A small herd of donkeys was introduced in a coastal dune reserve `Houtsaegerduinen' (ca. 80 ha) in Belgium, in order to slow down expansion of dominant grass and shrub species. The Houtsaegerduinen is a nutrient poor scrub-dominated dune system with a spatially heterogeneous vegetation pattern. Different aspects of the grazing behaviour (grazing time, bite rate, habitat use, diet composition) of the free-ranging donkeys are described and analysed. Behavioural data (of maximum six adult mares) were collected through continuous focal animal observation in three consecutive years (1998-2001). Temporal variation in grazing time, habitat use and diet composition was determined. During daylight, donkeys spent most of their time on grazing (56%). In all 3 years, grazing time was significantly shorter in summer (45% of their time), longest grazing times were achieved in spring (64%). In spring, the donkeys also achieved the highest bite rate (21.5 bites/min). The grassy habitat was preferred for foraging in all seasons, while the use of scrub and woodland was variable over time. Averaged over the four seasons, the general diet consisted for 80% of graminoids, 10% of forbs and 10% of woody plants. However, diet composition varied not only among seasons and years, but depended also on the foraged habitat type. We discuss the possible role of the donkeys in nature management. |
