Title Stimulation of food intake in horses by diazepam and promazine Type Journal Article
Year (up) 1976 Publication Pharmacology, biochemistry, and behavior Abbreviated Journal Pharmacol Biochem Behav
Volume 5 Issue 4 Pages 495-497
Keywords Age Factors; Animals; Diazepam/*pharmacology; Diet; Feeding Behavior/*drug effects; Female; Horses/*physiology; Male; Promazine/*pharmacology; Stimulation, Chemical
Abstract In two adult horses doses of 0.02-0.03 mg/kg diazepam, intravenously, increased 1 hr intake 54-75% above control levels. Intake was stimulated when the diet was a high grain, calorically dense one and also when the diet was a high fiber, calorically dilute one. Two young rapidly growing weanling horses showed an even more pronounced stimulation of intake. Following diazepam 1 hr intake was increased 105-240% above control lelvels. Promazine at a dose of 0.5 mg/kg also stimulated intake in adult horses, but not as markedly as did diazepam. A transquilizer and a neuroleptic appear to have a stimulatory eff upon short-term intake in horses.

Volume 66 Issue 1 Pages 73-81
Keywords Aggression; Animals; *Behavior, Animal; Cats; Chickens; Dogs; Education, Veterinary; Goats; Horses; Humans; Maternal Behavior; Mice; New York; Sexual Behavior, Animal; Sheep; Sleep; Social Behavior; Social Dominance; Swine
Abstract Knowledge of animal behavior is an important asset for the veterinarian; therefore a course in veterinary animal behavior is offered at the New York State College of Veterinary Medicine as an elective. The course emphasizes the behavior of those species of most interest to the practicing veterinarian: cats, dogs, horses, cows, pigs and sheep. Dominance heirarchies, animal communication, aggressive behavior, sexual behavior and maternal behavior are discussed. Play, learning, diurnal cycles of activity and sleep, and controls of ingestive behavior are also considered. Exotic and zoo animal behaviors are also presented by experts in these fields. The critical periods of canine development are related to the optimum management of puppies. The behavior of feral dogs and horses is described. The role of the veterinarian in preventing cruelty to animals and recognition of pain in animals is emphasized. Whenever possible behavior is observed in the laboratory or on film.

Title Dominance hierarchies in domestic horses Type Journal Article
Year (up) 1978 Publication Applied Animal Ethology Abbreviated Journal Appl. Animal. Ethol.
Volume 4 Issue 3 Pages 273-283
Keywords
Abstract Dominance hierarchies were studied in 11 herds of domestic horses and ponies (Equus caballus). A paired feeding test was utilized to establish the dominance--subordination relationship between each pair of animals in a herd. Aggressive actions, threats, bites, kicks and chases were also recorded. In small herds linear hierarchies were formed, but in large herds triangular relationships were observed. Aggression was correlated with dominance rank. Body weight, but not age, appear to affect rank in the equine hierarchy. Juvenile horses were more likely to share feed with each other than were adult horses and were usually subordinate to adult horses. The daughters of a dominant mare were dominant within their own herds.

Title Stability of equine hierarchies and the prevention of dominance related aggression Type Journal Article
Year (up) 1980 Publication Equine veterinary journal Abbreviated Journal Equine Vet J
Volume 12 Issue 1 Pages 15-18
Keywords *Aggression; Animals; *Behavior, Animal; Feeding Behavior; Female; *Hierarchy, Social; *Horses; Humans; Male; Maternal Behavior; *Social Dominance
Abstract The dominance hierarchy of a herd of 10 Thoroughbred mares was determined twice, at an interval of 18 months, using paired feeding tests. Each mare's rank was correlated significantly between the 2 tests. This indicated that the hierarchy within the herd was stable. The offspring of dominant and subordinate mares were also tested for dominance in their own age groups. The offspring of dominant mares tended to be near the top of the hierarchy while those of middle and low ranking mares were not consistently found in the middle or bottom of their own hierarchies. Paired feeding tests were carried out on 8 ponies. During tests the time that each pony spent eating and the ponies' aggressive interactions were recorded. Two situations were used. Each pony-pair was tested when both ponies were in the same paddock and also when they were separated by a rail fence. The subordinate ponies spent significantly more time eating and the domonant pony was significantly less aggressive, when the pony-pair was separated by a fence than when they were in one paddock. It was concluded that the dominance hierarchies of adult horse groups changed very little over time and that the foals of dominant mares will tend to be dominant in their own age groups. Management practices can be used to reduce aggression and consequent injury that may arise in group feeding situations.

Title Review of some research areas of applied and theoretical interest in domestic animal behavior Type Journal Article
Year (up) 1980 Publication Applied Animal Ethology Abbreviated Journal Appl. Animal. Ethol.
Volume 6 Issue 2 Pages 111-119
Keywords
Abstract There are numerous areas worthy of study in the field of domestic animal behavior or applied ethology. In this paper a few areas are offerred as particularly worthy of attention. These areas are worthwhile either because they have received little or no study and are of basic interest or because they have application to current problems of livestock production. The study of cat behavior falls in the former category. Neither the food and water sources, the reproductive success rate nor even the social interactions of cats in the large populations found in both rural and urban environments are known. Pigs as a species have already been the subjects of many behavior studies; nevertheless, there are still gaps in our knowledge of the underlying principles of swine behavior. The physiological basis of maternal behavior, for example, has not been studied in swine or in any domestic species. The sensory basis of udder location by the neonatal piglet deserves study also. Some aspects of olfactory and vocal communication of pigs have been studied, but only one of what may be a large number of pheromones of pigs has been chemically identified. The message conveyed by the vocal interactions between adult swine of the same sex is unknown, as is the role of facial and postural expressions in porcine communication. The two major problems of pig behavior under conditions of intensive livestock management are tail biting and reproductive failure. The application of behavioral techniques to these problems might help to attenuate those problems as well as broaden our understanding of normal pig behavior. Horse behavior has also been a relatively neglected field of study. Of particular interest is the significance of the flehmen gesture used by both mares and stallions in a variety of situations. Flehmen may be related to the function of the vomeronasal organ, but both observational and physiological studies should be performed to verify the hypothesis.

Title Learning ability of orphan foals, of normal foals and of their mothers Type Journal Article
Year (up) 1982 Publication Journal of animal science Abbreviated Journal 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.
