  Title The foraging efficiency of great tits (Parus major L.) in relation to light intensity Type Journal Article
  Year 1979 Publication Animal Behaviour. Abbreviated Journal Anim. Behav.  
  Volume 27 Issue (down) Part 1 Pages 237-241  
  Keywords  
  Abstract I report an experiment aimed at testing whether foraging efficiency of great tits is limited by light intensity at the time of the dawn chorus. Captive great tits hunting for prey under different luminance conditions were less successful in finding prey when foraging, hunted for a lower proportion of their time, and handled individual prey items for longer when luminance was under approximately 7 cd/m2. This luminance is not reached in the field until after the time of the dawn chorus, suggesting that in the early morning foraging is limited by light intensity. I suggest that a satisfactory functional explanation of the dawn chorus must take into account the comparatively low foraging opportunity early in the morning, as well as the factors affecting the opportunity for singing and other territorial activities.

  Title Ecological Interactions Involving Feral Horses and Predators: Review with Implications for Biodiversity Conservation Type Journal Article
  Year 2021 Publication The Journal of Wildlife Management Abbreviated Journal Jour. Wild. Mgmt.  
  Volume n/a Issue (down) n/a Pages  
  Keywords apparent competition; artificial selection; community ecology; conservation; feral horse (Equus ferus caballus); life history; predator-prey dynamics  
  Abstract ABSTRACT For many ecosystems, feral horses are increasingly becoming an important if not dominant component of ungulate biomass and hence influence on community dynamics. Yet we still know little of how horses contribute to key ecological interactions including predator-prey and indirect competitive relationships at a community level. Notably, feral species like horses can exhibit life-history traits that differ from that of native (mainly artiodactyl) herbivore competitors. Artificial selection for traits like increased, early, or extended reproduction that have yet to be reversed by natural selection, coupled with naturally selected differences in anatomy and behavior, in addition to unique management objectives for horses compared to other species, means that the dynamics of feral horse populations are not likely to align with what might be expected of other large herbivores. Unexpected population dynamics and inherent biological asymmetries between native ungulates and feral horses may therefore influence the former via direct competition for shared resources and through enemy-mediated interactions like apparent competition. In several localities feral horses now co-exist with multiple native prey species, some of which are in decline or are species at risk. Compounding risks to native species from direct or indirect competitive exclusion by horses is the unique nature and socio-political context of feral horse management, which tends towards allowing horse populations to be limited largely by natural, density-dependent factors. We summarize the inherent asymmetries between feral horse biology and that of other ungulate prey species with consequences for conservation, focusing on predator-prey and emerging indirect interactions in multi-prey systems, and highlight future directions to address key knowledge gaps in our understanding of how feral horses may now be contributing to the (re)structuring of food webs. Observations of patterns of rapid growth and decline, and associated skews in sex ratios of feral horse populations, indicate a heightened potential for indirect interactions among large ungulate prey species, where there is a prevalence of feral horses as preferred prey, particularly where native prey are declining. In places like western North America, we expect predator-prey interactions involving feral horses to become an increasingly important factor in the conservation of wildlife. This applies not only to economically or culturally important game species but also at-risk species, both predators (e.g., wolves [Canis lupus], grizzly bears [Ursus arctos]) and prey (e.g., woodland caribou [Rangifer tarandus caribou]), necessitating an ecological understanding of the role of horses in natural environments that goes beyond that of population control. ? 2021 The Wildlife Society.

  Title Automatic feeding systems for horses in group housing systems with regard to animal welfare. Part 1: Feeding stalls versus automatic feeding systems Type Journal Article
  Year 2010 Publication Tierärztliche Praxis Großtiere Abbreviated Journal Tierärztl Prax  
  Volume 38 Issue (down) G Pages 363-370  
  Keywords Pferd, Fütterungseinrichtungen, soziale Interaktionen, Herzfrequenz, Verletzungsrisiko, Betriebseinfluss [Horse, feeding stations, social interactions, heart rate, risk of injury, individual farm management]  
  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.]

  Title Automatic feeding systems for horses in group housing systems with regard to animal welfare. Part 2: Comparison of different automatic feeding systems Type Journal Article
  Year 2011 Publication Tierärztliche Praxis Großtiere Abbreviated Journal Tierärztl Prax

  Abstract Ziel: Überprüfung der Tiergerechtheit von in der Bauweise unterschiedlichen

Futterabrufstationen für Pferde in Gruppenhaltung anhand ethologischer

und physiologischer Parameter. Material und Methoden: In 32

Offenlaufställen (452 Pferde) mit computergesteuerten Abrufstationen

für Kraftfutter und Heu erfolgten kontinuierliche Direktbeobachtungen

für je einen 24-Stunden-Tag (Tortenstückverfahren). Erfasst wurden: Aufenthaltsdauer,

Besuchshäufigkeit, Droh- und Meideverhalten im Fütterungsbereich,

Blockaden sowie Herzfrequenz und Integumentverletzungen.

Ergebnisse: Eine Durchlaufstation reduzierte die Zahl der Auseinandersetzungen

im Fütterungsbereich signifikant. Ansonsten erhöhten die

für das fressende Pferd tiergerechten Varianten (Fressstand mit Eingangssperre,

ohne Austreibehilfe) Besuchshäufigkeit und Aufenthaltsdauer und

steigerten somit auch die Anzahl an Drohgesten je Tier und Tag. Insgesamt

betrachtet kann jedoch die Anzahl an sozionegativen Interaktionen

im Fütterungsbereich der Abrufstationen als relativ gering eingestuft

werden. Die Herzfrequenz lag im Warteareal bei den meisten Pferden im

physiologischen Bereich (45,1 ± 12,42 Schläge/min), erhöhte sich jedoch

in der Abrufstation um ca. 20 Schläge/min. Einige Tiere zeigten möglicherweise

stressbedingt kurzfristig auffallend hohe Werte (≥ 100 Schläge/

min). Integumentverletzungen im Zusammenhang mit dem Fütterungssystem

traten nicht auf. Der wichtigste Einflussfaktor auf die Untersuchungskriterien

war der Betrieb (Fläche, Konzeption, Management).

Schlussfolgerung: Durchlaufstationen sind pferdegerechter als Rücklaufstationen.

Nicht tiergerecht sind Stationen mit stromführender Austreibehilfe.

Weitere bauliche Unterschiede der derzeitigen Futterabrufstationen

dürften eher von untergeordneter Bedeutung sein, vor allem da

Flächengebot und Konzeption der Offenstallanlage sowie das Management

die überprüften Kriterien zur Tiergerechtheit maßgeblich beeinflussen.

Untersuchungen zur Abklärung der Ursache für die vereinzelt aufgetretenen

sehr hohen Herzfrequenzwerte sollten durchgeführt werden.

Objective: Comparison with regard to animal welfare of different automatic

feeding systems for hay and concentrate in group housing systems

for horses using parameters of ethology and physiology. Material and

methods: Parameters of research comprised: duration of stay, frequency

of visit, threatening behaviour with and without risk of injury, and avoiding

behaviour as well as heart rate and injuries of the integument. 452

horses were observed at the feeding area of 32 run-out-sheds. Every group

of horses was continuously observed following the pie chart system for

24 hours. Results: The “walk-through” station significantly reduced the

number of conflicts in the feeding area, whereas those systems which are

appropriate for the feeding horses (feeding station with access barrier and

without stimulation device by electric shock) led to a higher frequency of

visits and a longer duration of stay resulting in more threatening gestures.

However, the number of negative interactions in the feeding area of the

feeding systems can all together be classified as relatively insignificant.

The heart rate was within the physiological range (45.1 ± 12.42 beats/min)

in the waiting area, but increased by approximately 20 beats/min on average

within the feeding station. Some horses showed a very high heart rate

(≥ 100 beats/min) while entering the feeding station, possibly stress-related.

There were no injuries of the integument associated with the feeding

systems. The most important factor of the observation criteria was the

individual group housing system with its different dimensions, conception

and management. Conclusion: “Walk-through” stations are better than

”walk-back” stations with regard to animal welfare. Likewise, automatic

feeding stations with a current-carrying stimulation device are not supportive

of good welfare. The other differences between the constructions

of feeding stations of present systems are probably of less importance, particularly

as it was shown that the stable (management, stable area, conception)

had a significant influence on the surveyed parameters. Investigations

to obtain information on the cause for the sporadic occurrence of

very high heart rate values should be undertaken.]

  Title The Behaviour of Stallions in a Semiferal Herd in Iceland: Time Budgets, Home Ranges, and Interactions Type Journal Article
  Year 2012 Publication International Journal of Zoology Abbreviated Journal  
  Volume 2012 Issue (down) Article ID 162982 Pages  
  Keywords  
  Abstract A permanent herd of Icelandic horses with four stallions and their harems was studied for a total of 316 hours in a large pasture (215 ha) in May 2007 in Iceland. Interactions between stallions of different harems and other aspects of the horses' behaviour were studied. One stallion and nine horses were introduced into the pasture prior to the study to examine the reactions of the resident stallions to a newcomer. The stallions spent significantly less time grazing than other horses and were more vigilant. Home ranges overlapped, but harems never mixed. The stallions prevented interactions between members of different harems indirectly by herding. Generally, interactions between resident stallions were nonviolent. However, encounters with the introduced stallion were more aggressive and more frequent than between the other stallions. Here, we show that four harems can share the same enclosure peacefully. The social network seems to keep aggression at a low level both within the harems and the herd as a whole. We encourage horse owners to consider the feasibility of keeping their horses in large groups because of low aggression and because such a strategy gives the young horses good opportunities to develop normally, both physically and socially.

  Year 2006 Publication Journal of Animal Physiology and Animal Nutrition Abbreviated Journal J Anim Physiol Anim Nutr (Berl)  
  Volume 90 Issue (down) 9-10 Pages 414-420

  Abstract The objective of this study was to determine the efficacy of supplementation of Dynamic Trio 50/50, a bee pollen-based product, to improve physical fitness, blood leukocyte profiles, and nutritional variables in exercised horses. Ten Arabian horses underwent a standardised exercise test (SET), then were pair-matched by sex and fitness and randomly assigned to BP (receiving 118 g of Dynamic Trio 50/50 daily) or CO (receiving 73 g of a placebo) for a period of 42 days. A total collection was conducted from days 18 to 21 on six geldings to determine nutrient retention and neutral detergent fibre (NDF) and acid detergent fibre (ADF) digestibility. Horses were exercise conditioned and completed another SET on day 42. V160 and V200 were calculated from SET heart rates (HR). Lactate, glucose, haematocrit (HT) and haemoglobin (HB) concentrations were determined from SET blood samples. Total leukocyte count, and circulating numbers of various leukocytes and IgG, IgM and IgA concentrations were determined in rest and recovery blood samples from both SETs. Geldings on BP (n = 3) ate more feed than CO. BP had less phosphorus excretion, and tended to retain more nitrogen. BP tended to digest more NDF and ADF while having lower NDF digestibility and tending to have lower ADF digestibility. No treatment differences existed for V160 and V200, HR, lactate, HT and HB. There was a trend for lymphocyte counts to be lower in BP than CO on day 42. Dynamic Trio 50/50 supplementation may have a positive effect on performance by helping horses in training meet their potentially increased nutrient demands by increasing feed intake and thus nutrient retention.
