Title Behaviour, social interactions and lesion scores of group-housed sows in relation to floor space allowance Type Journal Article
Year 1998 Publication Applied Animal Behaviour Science Abbreviated Journal Appl. Anim. Behav. Sci.
Volume (up) 59 Issue 4 Pages 307-316
Keywords Pig-social behaviour; Space requirements; Anomalous behaviour
Abstract The space allowance appropriate for sows in group housing remains scientifically undefined, since the social space requirement of a group of animals and the factors which affect this are unknown. Eight established groups of six pregnant, multiparous sows were used in a replicated Latin Square design of experiment, with 7 day periods, to compare four pen sizes providing 2.0, 2.4, 3.6 or 4.8 m2/sow. For the last 48 h of each 7 day period, a continuous video recording was made to determine general behaviour and all social interactions. Time spent rooting increased progressively with increasing space allowance, whereas time spent sitting and standing inactive were both progressively reduced. The total frequency of social interactions and aggressive behaviour both increased with decreasing space allowance. The Attack:Retreat ratio was significantly higher, and the Avoidance Index significantly lower, in the smallest pen. All body regions had the highest count of lesions after sows had been in the smallest pen, with damage levels being reduced as pen area increased. Analysis of body lesion scores, combining incidence and severity, gave the same treatment effects. In conclusion, the results indicated that a minimum space of between 2.4 and 3.6 m2/sow was necessary in the conditions of this experiment to promote good welfare. This result cannot be generalised to situations of different group size, group stability or feeding method.

Title Effects of observational learning on acquisition of an operant response in horses Type Journal Article
Year 1999 Publication Applied Animal Behaviour Science Abbreviated Journal Appl. Anim. Behav. Sci.
Volume (up) 61 Issue 3 Pages 187-199
Keywords Horse; Observational learning; Stereotyped behaviour; Operant behaviour; Breed influence; Age influence
Abstract The effect of observational learning on the acquisition of an operant response was examined in eighteen riding horses and ponies. The test horses were randomly divided into three groups of six and individually exposed to one of three treatments. An additional horse was trained as a demonstrator, to perform the operant response. The observer horses watched either the demonstrator performing the bin-opening response (Group D+B); the demonstrator standing passively (Group D); or the operant bin in the absence of the demonstrator (Group B). Observers had access to and were free to interact with an identical bin during testing. Observers in Groups D+B and D were socially familiar with the demonstrator. Each test horse was tested once a day for 10 days. An ANOVA revealed no significant differences between treatment groups in the number of responses or the time taken to reach the learning criterion. However, there were highly significant differences between breed types, with non-warmbloods performing more bouts of opening the bin and feeding (p=0.02), feeding from the bin sooner (p=0.01) and reaching the criterion for learning sooner than warmbloods (p=0.05). There was also a significant negative linear relationship between horses' ages and time spent investigating the bin, with younger horses performing more investigative behaviour (y=-3.08x+106.86; p=0.02).

Title Effects of handling on behaviour and heart rate in Konik horses: comparison of stable and forest reared youngstock Type Journal Article
Year 1999 Publication Applied Animal Behaviour Science Abbreviated Journal Appl. Anim. Behav. Sci.
Volume (up) 62 Issue 1 Pages 1-11
Keywords Handling; Behaviour; Heart rate; Horses; Rearing
Abstract Thirty foals and young Konik horses born in 3 consecutive years and reared up to weaning either in a forest reserve (R) or conventional stable (S) were compared with respect to behavioural reactions and heart rate (HR) during handling manipulations. The foals were randomly allocated within sex and rearing group to one of two handling treatments. Intensively handled (IH) foals received a 10-min handling, 5 days/week, beginning at the age of 2 weeks (S foals) or 10 months (R foals), and lasting up to the age of 24 months. During handling IH foals were haltered, touched, rubbed and their feet were picked up; non-handled (NH) foals were not handled except for routine or emergency veterinary care. The horses were tested at the age of approximately 6 months (S only) and 12, 18 and 24 months of age. In a test comprising catching the horse on a paddock, leading away from and towards the stable, picking up feet and being approached by an unfamiliar person, the horses' behaviour was scored and the HR was recorded telemetrically. The IH horses scored better as far as manageability behaviour is concerned (P<0.001) and demonstrated lower HR than the NH ones and the S horses scored better than R ones (P<0.001). Fillies demonstrated higher HR than colts (P=0.007). Youngstock of all groups tended to be less manageable at the age of 24 months than at 18 months. Differences between youngstock stemming from particular harems from the reserve seem to be related to differences in accidental contact with people visiting the forest reserve.

Title “Intervenors” in agonistic interactions amongst domesticated goats Type Journal Article
Year 1998 Publication Zeitschrift fur Säugetierkunde Abbreviated Journal Z. Säugetierk.
Volume (up) 63 Issue 5 Pages 266-272
Keywords Behaviour; Domestication; Goat; Intervention; Rank order
Abstract Social behaviour was observed in individually marked goats in two herds. The goats from one herd (n = 98) were horned, those of the other herd (n = 83) were polled. By recording agonistic interactions within the herds, a dominance index was determined for each animal. In both herds, intervention took place. Intervention is defined as one animal pushing in between two fighters, and thus ending the fight. More cases of intervention took place per individual animal amongst the horned goats than amongst the polled ones. Goats which intervened in fights on several occasions usually had a high dominance index. Members of the herd which were observed intervening only once had an average dominance index in both herds of almost 0.5. In some cases, goats very low in the rank order intervened a fight. Only rarely did the intervenors have a lower dominance index than the two fighters. In 103 cases, the direct dominance relationship between a fighting animal and the intervenor was known. In 95 cases (92.2%), the intervenor was dominant to the herd member in this fight and in just eight cases (7.8%), it was subordinate. It could not be determined what advantage the intervenor gained from its activity. It is possible that, at least in certain cases, a particularly relationship existed between the intervenor and one of the fighters.

Title Comparison of social ranks based on worm-running and aggressive behaviour in young domestic fowl Type Journal Article
Year 2004 Publication Behavioural Processes Abbreviated Journal Behav. Process.
Volume (up) 65 Issue 1 Pages 79-86
Keywords Aggression; Social behaviour; Dominance; Play; Chickens; Animal welfare
Abstract Worm-running is behaviour in which a chick runs carrying a worm-like object while flock mates follow and attempt to grab the object from its beak. We hypothesised that social ranks based on worm-running frequency are stable over time and are positively correlated with social ranks based on success in aggressive interactions when older. At 8-12 days of age, we scored worm-running in 17 groups of 12 female White Leghorn chicks during three 10-min tests. Based on instantaneous scans at 5-s intervals, the bird carrying the `worm' most often was placed in rank one and so on down the rank order. These tests were repeated at 68-70 days of age. An aggression index for each bird was calculated as the number of aggressive acts given, divided by the number given and received, during three 1-h observation periods when the birds were 68-70 days. Ranks obtained in worm-running tests were positively correlated over the two age periods (P<0.05) but were not correlated with ranks based on the aggression index (P>0.05). Our results indicate that worm-running ranks are not predictive of success in aggressive interactions. Instead, worm-running fits some criteria for play.

Title Promiscuous behaviour disrupts pregnancy block in domestic horse mares Type Journal Article
Year 2011 Publication Abbreviated Journal Behavioral Ecology and Sociobiology
Volume (up) 65 Issue 8 Pages 1567-1572
Keywords Foetal loss; Domestic horse; Bruce effect; Sexual behaviour
Abstract Based on questionnaires from horse breeders, we found that bringing a pregnant mare which had been mated away from home into a vicinity of a familiar male who was not the father of her foetus increased probability of pregnancy disruption. These mares aborted in 31% of cases, while none of those mated within the home stable aborted. Repeated sexual activity either by a stallion or dominant gelding from the normal home group was observed shortly after the mare came from away-mating. Pregnant mares isolated from home males by a fence were even seen soliciting them over the fence. We speculate that, once returned to the home “herd”, and introduced to familiar males, mares were more likely to terminate their pregnancy to save energy and avoid likely future infanticidal loss of their progeny by dominant male(s) of the home social group. This is a newly discovered phenomenon where a mare manipulates the male’s paternity assessment by promiscuous mating. It may explain a common increased incidence of foetal loss in domestic horses occurring in nearly 40% of pregnancies. We conclude that the common practice of transporting the mare for mating and then bringing her back to an environment with males, stallions or geldings, which did not sire the foetus, is the main cause of high percentages of pregnancy disruption in domestic horses.

Title Bewertung einer Faltschieberanlage in einem Reitstall mit Paddockboxen[Assessment of a v-form scraper in a horse barn with paddock boxes] Type Journal Article
Year 2014 Publication Landtechnik, Agricultural Engineering, Abbreviated Journal
Volume (up) 68 Issue 4 Pages 242-247
Keywords Entmistungstechnik, Arbeitswirtschaft, Pferdeverhalten [Manure removal systems, working time requirement, horse behaviour]
Abstract In der vorliegenden Untersuchung werden in einem Praxisbetrieb die Verfahrenskosten eines

Faltschiebers erhoben. Aufgrund des reduzierten Arbeitszeitaufwandes ergibt sich durch den

Einsatz des Faltschiebers eine jährliche Kostenersparnis in Höhe von 78 € je Pferd. Durch die

Mechanisierung der Entmistung kann fast 30 % der Arbeitszeit in der Pensionspferdehaltung

eingespart werden. Beim Einsatz einer Entmistungstechnik spielt jedoch nicht nur die Ökonomie,

sondern darüber hinaus auch das Pferdeverhalten eine Rolle. Im selben Praxisbetrieb wird

nach Installation der Faltschieberanlage das Pferdeverhalten beim Erstkontakt mit dem Schieber

beobachtet. Dabei zeigt sich, dass die Pferde den direkten Kontakt mit der Entmistungstechnik

und somit kritische Situationen vermeiden.

[In the survey at hand, the procedural costs for a v-form scraper are gathered. In the process,

it is found that due to the reduced working time requirement the use of a v-form scraper

saves € 78/horse/year. The mechanization of manure removal can reduce working time in

horse keeping by almost 30 percent. However, using manure removal systems, the profitability

is not the only crucial criteria. The behaviour of the horses plays an essential role, too.

Moreover the horses’ behaviour when first encountering the manure scraper is observed. The

study reveals that the horses avoid contact with the scraper and thereby also shirk critical

situations.]

Title Ethologische Untersuchung von Heuraufen in der Pferdehaltung [Ethological investigation of hayracks in equine husbandry] Type Journal Article
Year 2014 Publication Landtechnik Abbreviated Journal Landtechnik
Volume (up) 69 Issue 5 Pages 239-244
Keywords Pferdehaltung, Fressverhalten, Futterraufen [horse keeping, feeding behaviour, roughage racks]
Abstract Eine tiergerechte, physiologisch und anatomisch auf die Bedürfnisse der Pferde ausgerichtete

Raufutterversorgung sollte die Kaubedürfnisse und die Beschäftigungszeiten von Pferden

ausreichend berücksichtigen. Daher – und auch aufgrund des bestehenden Kostendrucks bei

Raufutter – steigt das Interesse an Raufutterraufen, durch die möglicherweise die Futteraufnahmezeiten

verlängert sowie Futterverluste minimiert werden können.

Die vorliegende Untersuchung vergleicht das Fressverhalten und die Körperhaltung von acht

Pferden beim Einsatz von drei unterschiedlichen Futterraufen mit der Bodenfütterung in Einzelboxenhaltung.

Die Ergebnisse dieser Studie lassen den Schluss zu, dass der Einsatz von

Raufutterraufen die Futteraufnahmezeiten verlängert und somit längere Beschäftigungszeiten

für die Futteraufnahme gewährleistet werden. Außerdem konnte festgestellt werden, dass die

Pferde das Raufutter bei einer der drei untersuchten Raufen überwiegend mit natürlicher Kopf-

Hals-Haltung aufnahmen.

[Regarding the species horse, an appropriate supply of roughage should take into account the

need to chew as well as the need for occupation. In this context, and due to the current cost

pressure for hay, the interest in roughage racks increases. It is assumed that roughage racks

could help to extend the feeding time and reduce food losses.

The present study places the emphasis on the observation of the feeding behaviour of eight

horses in single horse boxes. Three different roughage racks are compared to traditional feeding

on the floor. On the basis of the results it may be concluded that the use of roughage racks

extends the feeding time and thus ensures longer occupation. In one of the three roughage

racks investigated the horses mainly eat in a natural posture of their head and neck.]

Title Effects of Rearing Methods of Heifers during Milk Replacement Period Type Journal Article
Year 2002 Publication Czech Journal of Animal Science Abbreviated Journal Czech J. Anim. Sci
Volume (up) 71 Issue 4 Pages 509-516
Keywords Heifers, behaviour, maze, feeding, housing
Abstract Fifty-eight Holstein heifer calves were assigned to one out of three treatment groups after having nursed by their mothers for the first week: BN) individual hutch, bucket with nipple n=25; DF)loose housing pen, machine milk feeder, n=16; NC) loose housing pen, nursing cow, n=17. After weaning at 8 weeks, all calves were kept in group pens. At 15 weeks of age, the behaviour in the 6-unit maze (16.4 – 4.5 m) was determined. On the first observation day, the calves were tested five times (the first one for training); on the second day there were four runs. The calves had to solve two tasks. In task A, the passage was open on the left side, and on the right side (task B) on the next day. We were testing the following hypothesis: the speed of traversing the maze is affected by the rearing system. The slowest were NC calves. On the first day (task A), the average time to traverse the maze among treatments DF (43.9 s), BN (53 s) and NC (111.3 s) was different (F = 8.26*, P = 0.0007). On the second day (task B), the averages were: BN 77.1 s, DF 83.8 s and DC 166.6 s (F=8.17*, P = 0.0008). The results indicate that the feeding method and housing used to rear calves may have a significant impact on their maze behaviour.

Title Behavioural responses of red deer to fences of five different designs Type Journal Article
Year 2001 Publication Applied Animal Behaviour Science Abbreviated Journal Appl. Anim. Behav. Sci.
Volume (up) 73 Issue 4 Pages 289-298
Keywords Red deer; Fence efficiency; Grazing behaviour
Abstract Capercaillie, a large species of grouse, are sometimes killed when they fly into high-tensile deer fences. A fence design which is lower or has a less rigid top section than conventional designs would reduce bird deaths, but such fences would still have to be deer-proof. The short-term behavioural responses of farmed red deer (Cervus elaphus) to fences of five designs, including four that were designed to be less damaging to capercaillie, were measured. Five deer were located on one side of a fence with a larger group (20 animals), from which they had been recently separated, on the other. The efficacy of fences in preventing deer from the small group from rejoining the larger group was also recorded. In addition to a conventional deer fence (C) the four new designs were, an inverted “L” shape (L), a fence with offset electric wire (E), a double fence (D) and a fence with four webbing tapes above (W). Four replicate groups of deer were each tested for 3 days with each fence design. Deer paced the test fence line relatively frequently (a proportion of 0.09 scan observations overall) but significantly less when deer were separated by fences E or C compared to L, W or D (overall difference between fence types, P<0.001). Deer separated by fence E spent significantly more time pacing perimeter fences than deer separated by fences of other types (overall difference between fence types, P<0.01) but deer separated by fence C maintained a low level of fence pacing overall. Analysis of behaviour patterns across the first day and the 3 days of exposure suggested that the novelty of the test fences, rather than the designs per se, influenced the behaviour of the deer. Over the course of the study, no deer crossed either C or L. Three deer crossed E and two deer crossed both W and D. On this basis, field testing, particularly of fence L, would be a useful next step.
