Title Ethologische Untersuchung von Heuraufen in der Pferdehaltung [Ethological investigation of hayracks in equine husbandry] Type Journal Article
Year 2014 Publication Landtechnik Abbreviated Journal (down) Landtechnik
Volume 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 Coat Clipping of Horses: A Survey Type Journal Article
Year 2019 Publication Journal of Applied Animal Welfare Science Abbreviated Journal (down) Journal of Applied Animal Welfare Science
Volume 22 Issue 2 Pages 171-187
Keywords Equine, thermoregulation, shaving, winter pelage removal
Abstract Coat clipping is a common practice in sport horses; however, timing, purpose, technique, and clips vary widely, as do the management and feeding of a clipped horse. The aim of this study was to collect data regarding common clipping practices. A questionnaire was published online in Germany and contained 32 questions. Four hundred ninety-eight people answered at least one question, and 373 individuals (7% male, 93% female; ages 14–59 years) completed all the questions. Clipped horses were predominantly used as sport horses (68%), and they were either clipped immediately before or during the winter season (88%) or year-round (7%). The clipping date was scheduled according to hair length (52%), sweat amount (47%), and drying time (47%). Participants primarily used two clips: the hunter clip and the blanket clip, both without clipping the head (23% each). The majority of the clipped horses wore a blanket day and night (> 90%). Future studies with observations in the field are needed to support survey data in an effort to develop welfare recommendations for clipping practices utilized with horses.

Title Early management of race-bred weanlings and yearlings on farms Type Journal Article
Year 2001 Publication Journal of Equine Veterinary Science Abbreviated Journal (down) J. Equine Vet. Sci.
Volume 21 Issue 6 Pages 279-283
Keywords Equine, management, growth, nutrition, marketing
Abstract A total of 58 Thoroughbred and Quarter Horse farms

that managed 1,987 weanlings and yearlings responded to

a survey designed to better characterize early management

of racing prospects. Average age at weaning was 5.5 months

and over half of all farms kept almost three-fourths of all

weanlings to be placed in pre-race training. Variation in

feeding practices was evident and while well over half

of all farms provided balanced nutrient supply to young

horses, 20% to 40% likely fed unbalanced diets. An obvious

preference existed for semi-confinement in young horses

with plenty of free exercise. The majority of farms reported

that young prospects were fed and managed for a moderate

rate of growth. Forced exercise occurred to a much larger

extent with yearlings than weanlings and 40% of farms

described the footing as soft, but not deep. Response to the

prevalence of developmental orthopedic diseases appeared

somewhat guarded, and average injury rate was low on

farms that attributed much of injury to horses playing too

hard. Technological advancements such as photoperiod

manipulation in broodmares were widely used, while

valuable tools such as body condition scoring were utilized

to a lesser extent.

Title Social referencing by young chimpanzees (Pan troglodytes) Type Journal Article
Year 1997 Publication Journal of Comparative Psychology Abbreviated Journal (down) J. Comp. Psychol.
Volume 111 Issue 2 Pages 185-191
Keywords happy & fear messages concerning novel objects from familiar human caregiver, social referencing, 14–41 mo old chimpanzees
Abstract Social referencing is the seeking of information from another individual and the use of that information to evaluate a situation. It is a well-documented ability in human infants but has not been studied experimentally in nonhuman primates. Seventeen young nursery-reared chimpanzees (14 to 41 months old) were observed in a standard social referencing paradigm in which they received happy and fear messages concerning novel objects from a familiar human caregiver. Each chimpanzee looked referentially at their caregiver, and the emotional messages that they received differentially influenced their gaze behavior and avoidance of the novel objects. It is concluded that chimpanzees can acquire information about their complex social and physical environments through social referencing and can use emotional information to alter their own behavior.

Title Learning ability of orphan foals, of normal foals and of their mothers Type Journal Article
Year 1982 Publication Journal of animal science Abbreviated Journal (down) J. Anim Sci.
Volume 55 Issue 5 Pages 1027-1032
Keywords Age Factors; Animals; Body Weight; Dominance-Subordination; Female; Horses/*physiology; *Learning; *Maternal Deprivation; Mothers/*psychology
Abstract The maze learning ability of six pony foals that had been weaned at birth was compared to that of six foals reared normally. The foals' learning ability was also compared to their mothers' learning ability at the same task; the correct turn in a single choice point maze. The maze learning test was conducted when the foals were 6 to 8 mo old and after the mothered foals had been weaned. There was no significant difference between the ability of orphaned (weaned at birth) and mothered foals in their ability to learn to turn left (6 +/- .7 and 5.1 +/- .1 trials, respectively) or to learn the reversal, to turn right (6.7 +/- .6 and 6.2 +/- .6 trials, respectively). The orphan foals spent significantly more time in the maze in their first exposure to it than the mothered foals (184 +/- 42 vs 55 +/- 15 s. Mann Whitney U = 7, P less than .05). The mothers of the foals (n = 11) learned to turn left as rapidly as the foals (5.9 +/- .7 trials), but they were slower to learn to turn right (9.8 +/- 1.4 vs 6.4 +/- .4 trials, Mann Whitney U = 33, P less than .05), indicating that the younger horses learned more rapidly. There was no correlation between the trials to criteria of the mare and those of her foal, but there was a significant negative correlation between rank in trials to criteria and age (r = -65, P less than .05) when data from the mare and foal trials were combined. The dominance hierarchy of the mares was determined using a paired feeding test in which two horses competed for one bucket of feed. Although there was no correlation between rank in the hierarchy and maze learning ability, there was a correlation between body weight and rank in the hierarchy (r = .7, P less than .05). This may indicate either that heavier horses are likely to be dominant or that horses high in dominance gain more weight. Maternal deprivation did not appear to seriously retard learning of a simple maze by foals, although the orphans moved more slowly initially. The lack of maternal influence on learning is also reflected in the lack of correlation between the mare's learning ability and that of her foal. Young horses appear to learn more rapidly than older horses.

Title Wood chewing by stabled horses: diurnal pattern and effects of exercise Type Journal Article
Year 1991 Publication Journal of Animal Science Abbreviated Journal (down) J. Anim Sci.
Volume 69 Issue 3 Pages 1053-1058
Keywords Animal Feed; Animals; *Behavior, Animal; *Circadian Rhythm; Female; Horses/*physiology; Male; *Mastication; *Physical Conditioning, Animal; Sodium Chloride/administration & dosage; Videotape Recording; Wood
Abstract Nine yearling horses, stabled in individual stalls, were used in a trial to determine the diurnal pattern of wood chewing and the effects of exercise on this behavior. The trial was a Latin square design conducted over three 2-wk periods during which each horse was exposed to each of the three following treatments: 1) no exercise (NE), 2) exercise after the morning feeding (AM), and 3) exercise in the afternoon (PM). Horses were fed a complete pelleted feed in the morning and both pelleted feed and long-stemmed hay in the afternoon. Exercise consisted of 45 min on a mechanical walker followed by 45 min in a paddock with bare soil. Each stall was equipped with two untreated spruce boards during each period for wood chewing. Wood chewing was evaluated by videotaping each horse for 22 h during each period, determining the weight and volume of the boards before and after each period, and by visual appraisal of the boards. Intake of trace mineralized salt was also measured. Wood chewing occurred primarily between 2200 and 1200. All measures of wood chewing were correlated when totals for the entire 6 wk were analyzed. When analysis was performed on 2-wk values, videotape results were not correlated with volume or weight loss of boards. Horses chewed more when on the NE treatment (511 s/d) than when on AM or PM (57 and 136 s/d, respectively; P less than .05). Salt intake tended to be greater for NE than for the other treatments (P less than .10).(ABSTRACT TRUNCATED AT 250 WORDS)

Title A comparison of Freund's Complete and Freund's Modified Adjuvants used with a contraceptive vaccine in wild horses (Equus caballus) Type Journal Article
Year 2005 Publication Journal of zoo and wildlife medicine : official publication of the American Association of Zoo Veterinarians Abbreviated Journal (down) J Zoo Wildl Med
Volume 36 Issue 4 Pages 610-616
Keywords Animals; Antibody Formation; Contraception, Immunologic/*veterinary; Estrus/drug effects; Female; Freund's Adjuvant/administration & dosage/adverse effects/*immunology; Horses/immunology/*physiology; *Vaccines, Contraceptive; Zona Pellucida/*immunology
Abstract Fifteen captive wild mares (Equus caballus) were treated with porcine zona pellucida contraceptive vaccine and either Freund's Complete Adjuvant (n = 7) or Freund's Modified Adjuvant (n = 8). All mares received a booster inoculation of porcine zona pellucida plus Freund's Incomplete Adjuvant a month later. Anti-porcine zona pellucida antibodies were measured over 10 mo following the initial inoculation. There were no significant differences in antibody titers at any point during the 10 mo, and seven of the eight mares in the Freund's Modified Adjuvant group were above the 60% level at the end of the study, which is considered to be the contraceptive threshold for horses. There were no significant differences in titers between pregnant and nonpregnant horses, nor was there a significant correlation between age and titers. One local injection site reaction occurred after booster treatment with Freund's Incomplete Adjuvant, and 11 healthy foals were born during the course of the study. These data suggest that Freund's Modified Adjuvant is an acceptable substitute for Freund's Complete Adjuvant in certain free-ranging and captive wildlife species.

Title Pharmacokinetics of altrenogest in horses Type Journal Article
Year 2007 Publication Journal of Veterinary Pharmacology and Therapeutics Abbreviated Journal (down) J Vet Pharmacol Ther
Volume 30 Issue 1 Pages 86-90

Abstract The Federation Equestre Internationale has permitted the use of altrenogest in mares for the control of oestrus. However, altrenogest is also suspicious to misuse in competition horses for its potential anabolic effects and suppression of typical male behaviour, and thus is a controlled drug. To investigate the pharmacokinetics of altrenogest in horses we conducted an elimination study. Five oral doses of 44 mug/kg altrenogest were administered to 10 horses at a dose interval of 24 h. Following administration blood and urine samples were collected at appropriate intervals. Altrenogest concentrations were measured by liquid chromatography-tandem mass spectrometry. The plasma levels of altrenogest reached maximal concentrations of 23-75 ng/mL. Baseline values were achieved within 3 days after the final administration. Urine peak concentrations of total altrenogest ranged from 823 to 3895 ng/mL. Twelve days after the final administration concentrations were below the limit of detection (ca 2 ng/mL).

Title Relationship between plasma testosterone concentrations and age, breeding season and harem size in Misaki feral horses Type Journal Article
Year 1998 Publication The Journal of veterinary medical science / the Japanese Society of Veterinary Science Abbreviated Journal (down) J Vet Med Sci
Volume 60 Issue 5 Pages 643-645
Keywords Age Factors; Animals; Animals, Wild; *Horses; Japan; Male; Reproduction; Seasons; Sexual Behavior, Animal; Sexual Maturation; *Social Behavior; Testosterone/*blood
Abstract Jugular vein blood samples were collected from 23 young and sexual mature feral stallions to examine the relationship between plasma testosterone concentration and age, breeding season or harem size. Testosterone concentration increased with the age of the stallions until they formed their own harems, at about 4 to 6 years old. Seasonal variations in testosterone concentrations were observed, and found to be significantly higher (P<0.001) throughout the breeding season than non-breeding season, from 3 years of age. Testosterone levels were correlated with harem size for individual stallions. It can be inferred from these results that there is a relationship between plasma testosterone concentration and age, breeding season and harem size.

Title The association between heart rate, heart rate variability, endocrine and behavioural pain measures in horses suffering from laminitis Type Journal Article
Year 2004 Publication Journal of Veterinary Medicine. A, Physiology, Pathology, Clinical Medicine Abbreviated Journal (down) J Vet Med A Physiol Pathol Clin Med
Volume 51 Issue 5 Pages 218-225

Abstract The objective of this study was to compare the stress response of horses suffering from laminitis after short- and long-term treatment with the intent to evaluate power spectral analysis of heart rate variability (HRV) for pain monitoring. Data were collected from 19 horses with acute or chronic exacerbating laminitis without known primary disease before and after treatment with non-steroidal anti-inflammatory drugs (NSAID). Recordings were carried out the day after admission to the equine hospital. Measurements were repeated on day 7 of the treatment. The recorded parameters included a clinical orthopaedic index (OLPI: Obel-grade plus hoof tester score), frequency of weight-shifting between contralateral limbs, mean beat-to-beat interval (R-R) duration, standard deviation of continuous R-R intervals, low- (LF) and high-frequency (HF) components of HRV, sympatho-vagal balance (LF/HF), and plasma concentration of cortisol, adrenalin and noradrenalin. The LF represents mainly sympathetic influences on the heart whereas HF is mediated by the parasympathetic tone. Weight-shifting and OLPI decreased significantly with treatment. The LF normalized units (n.u.) decreased after NSAID from 60.41 +/- 21.42 to 51.12 +/- 19.81 and was 49.33 +/- 22.64 on day 7, whereas HF n.u. increased from 35.07 +/- 20.02 to 43.14 +/- 18.30 and was 45.98 +/- 23.00 on day 7. Hormone levels showed no tendency to change with treatment. The OLPI was only correlated with LF/HF, LF and HF (R = 0.57, 0.55 and -0.54 respectively). Significant negative correlations existed between HFn.u. and weight-shifting frequency (R = -0.37), HFn.u. and adrenalin (R = -0.47), and HFn.u. and noradrenalin (R = 0.33). The LFn.u. only correlated positively with adrenalin. Cortisol levels were poorly associated with the other parameters. Determination of the sympatho-vagal influences on cardiac function may offer complementary information for reliable assessment of pain and may represent a valuable alternative method to catecholamine measurements.
