	Title	Relationship between locomotor forces, hoof position and joint motion during the support phase of the stride of galloping horses			Type	Journal Article
	Year	1993	Publication	Acta Anatomica	Abbreviated Journal	Acta Anat (Basel)
	Volume	146	Issue	2-3	Pages	200-204
	Keywords	Animals; Equipment Design; Hoof and Claw/physiology; Horses/physiology; Joints/physiology; Locomotion; Motor Activity/physiology; Physiology/instrumentation; Posture; Shoes; Transducers
	Abstract	Three methods were used simultaneously to determine the relationships between the vertical forces exerted on the hooves and the positions of the limbs and hooves at the times of peak vertical forces from 2 horses galloping on a track straightaway. Vertical forces were recorded from an instrumented shoe, fetlock joint motion was measured with an electrogoniometer and the angles of the carpus, fetlock and hoof were determined from slow-motion films. At hoof contact, the mean angles of the carpus and fetlock were 181-182 degrees and 199-206 degrees, respectively. Peak vertical forces on the heel occurred at or near maximum extension of the carpal and fetlock joints. Peak forces on the toe occurred during flexion of the fetlock joint and at mean hoof angles of 28-31 degrees from the horizontal. The mean angles of the hoof from the horizontal at the time of heel contact were 6-7 degrees. Hoof lift occurred at mean carpal angles of 173-174 degrees and mean fetlock angles of 199-200 degrees.

	Title	[M-mode echocardiography in dressage horses, class S jumping horses and untrained horses]			Type	Journal Article
	Year	1993	Publication	Zentralblatt fur Veterinarmedizin. Reihe A	Abbreviated Journal	Zentralbl Veterinarmed A
	Volume	40	Issue	4	Pages	292-306
	Keywords	Animals; Echocardiography/veterinary; Female; Heart Septum/ultrasonography; Heart Ventricles/ultrasonography; Horses/anatomy & histology; Male; *Physical Conditioning, Animal; Reference Values
	Abstract	Heart structures of 45 warmblooded horses were measured by M-mode-echocardiography. The current training level of 15 dressage horses (group I) and 15 show-jumping horses (group II) was category “S”. In the third group were 15 untrained horses. Four standardized transducer positions were determined for the m-mode echobeam, calibrated according to the two-dimensional real time technique. End systolic and end diastolic diameters of left ventricle, right ventricle, aortic root, interventricular septum and left ventricular wall, as well as motion pattern of heart wall, mitral valve and aortic valve of all horses were measured. The dressage horses showed a significant thickening of interventricular septum and left-ventricular wall compared with the show-jumping horses and the untrained horses. The end diastolic left ventricle diameter of the show-jumping horses was significantly larger than in the other groups. Compared to the untrained horses the show-jumping horses showed a significantly larger end systolic left ventricular wall diameter measured at the level of papillary muscle. It can be concluded, that an increase in heart mass in category “S” sport horses is attributed to their level of training.

	Title	Unravelling the ecology of influenza A virus			Type	Journal Article
	Year	1993	Publication	History and Philosophy of the Life Sciences	Abbreviated Journal	Hist Philos Life Sci
	Volume	15	Issue	1	Pages	23-32
	Keywords	Animals; Bird Diseases/epidemiology/history/microbiology; Birds; Ecology; History, 20th Century; Horse Diseases/epidemiology/history/microbiology; Horses; Humans; Influenza A virus/isolation & purification; Influenza, Human/epidemiology/history/microbiology/veterinary; Swine; Swine Diseases/epidemiology/history/microbiology; Zoonoses/history
	Abstract	For 20 years after the influenza A virus was discovered in the early 1930s, it was believed to be almost exclusively a human virus. But in the 1950s closely related viruses were discovered in diseases of horses, pigs and birds. Subsequently influenza A viruses were found to occur frequently in many species of birds, particularly ducks, usually without causing disease. Researchers showed that human and animal strains can hybridise thus producing new strains. Such hybrids may be the cause of pandemics in man. Most pandemics have started in China or eastern Russia where many people are in intimate association with animals. This situation provides a breeding ground for new strains of influenza A virus.

	Title	Generalization of a tactile stimulus in horses			Type	Journal Article
	Year	1993	Publication	Journal of the Experimental Analysis of Behavior	Abbreviated Journal	J Exp Anal Behav
	Volume	59	Issue	3	Pages	521-528
	Keywords	Animals; Behavior, Animal; Female; Horses; Male; Reinforcement (Psychology); Touch
	Abstract	Using horses, we investigated the control of operant behavior by a tactile stimulus (the training stimulus) and the generalization of behavior to six other similar test stimuli. In a stall, the experimenters mounted a response panel in the doorway. Located on this panel were a response lever and a grain dispenser. The experimenters secured a tactile-stimulus belt to the horse's back. The stimulus belt was constructed by mounting seven solenoids along a piece of burlap in a manner that allowed each to provide the delivery of a tactile stimulus, a repetitive light tapping, at different locations (spaced 10.0 cm apart) along the horse's back. Two preliminary steps were necessary before generalization testing: training a measurable response (lip pressing) and training on several reinforcement schedules in the presence of a training stimulus (tapping by one of the solenoids). We then gave each horse two generalization test sessions. Results indicated that the horses' behavior was effectively controlled by the training stimulus. Horses made the greatest number of responses to the training stimulus, and the tendency to respond to the other test stimuli diminished as the stimuli became farther away from the training stimulus. These findings are discussed in the context of behavioral principles and their relevance to the training of horses.

	Title	Directed forgetting in animals			Type	Journal Article
	Year	1993	Publication	Psychological bulletin	Abbreviated Journal	Psychol Bull
	Volume	113	Issue	3	Pages	513-532
	Keywords	Animals; Behavior, Animal; Cognition; Columbidae; Conditioning (Psychology); Discrimination Learning; Female; Humans; Male; Memory Disorders/psychology; Reinforcement (Psychology); Task Performance and Analysis
	Abstract	Directed-forgetting research with animals suggests that animals show disrupted test performance only under certain conditions. Important variables are (a) whether during training, the cue to forget (F cue) signals nonreward (i.e., that the trial is over) versus reward (i.e., that reinforcement can be obtained) and (b) given that reinforcement can be obtained on F-cue trials, whether the post-F-cue response pattern is compatible with the baseline memory task. It is proposed that some findings of directed forgetting can be attributed to trained response biases, whereas others may be attributable perhaps to frustration-produced interference. It is suggested that directed forgetting in animals should be studied using procedures similar to those used to study directed forgetting in humans. This can be accomplished by presenting, within a trial, both to-be-remembered and to-be-forgotten material.

	Title	Varieties of learning and memory in animals			Type	Journal Article
	Year	1993	Publication	Journal of experimental psychology. Animal behavior processes	Abbreviated Journal	J Exp Psychol Anim Behav Process
	Volume	19	Issue	1	Pages	5-14
	Keywords	Animals; Association Learning; Birds; Conditioning, Classical; Evolution; Imprinting (Psychology); Learning; Memory; Social Environment; Species Specificity; Taste
	Abstract	It is often assumed that there is more than one kind of learning--or more than one memory system--each of which is specialized for a different function. Yet, the criteria by which the varieties of learning and memory should be distinguished are seldom clear. Learning and memory phenomena can differ from one another across species or situations (and thus be specialized) in a number of different ways. What is needed is a consistent theoretical approach to the whole range of learning phenomena, and one is explored here. Parallels and contrasts in the study of sensory systems illustrate one way to integrate the study of general mechanisms with an appreciation of species-specific adaptations.

	Title	Progression of femoropatellar osteochondrosis in nine young horses. Clinical, radiographic and arthroscopic findings			Type	Journal Article
	Year	1993	Publication	Veterinary Surgery : VS : the Official Journal of the American College of Veterinary Surgeons	Abbreviated Journal	Vet Surg

	Keywords	Animals; Arthroscopy/veterinary; Debridement/veterinary; Exudates and Transudates; Female; Femur; Follow-Up Studies; Horse Diseases/diagnosis/radiography/surgery; Horses; Lameness, Animal/etiology; Male; Osteochondritis/diagnosis/radiography/surgery/*veterinary; Patella; Stifle; Treatment Outcome
	Abstract	The clinical and radiographic progression, and arthroscopic findings for nine young horses (< 1 year of age) with femoropatellar osteochondrosis (OCD) are presented. Horses had a 2 to 12 week history of bilateral (8 horses) or unilateral (1 horse) hindlimb lameness. The most consistent clinical signs included femoropatellar joint distention and bilateral hindlimb lameness. At the onset of clinical signs, radiographic lesions were not present (4 horses) or subtle (5 horses), but were easily identified on radiographs taken 4 to 24 weeks later. Arthroscopic surgery was delayed until radiographic changes became obvious. Surgical findings in 20 femoropatellar joints were most commonly osteochondral “flaps” located on the proximal lateral trochlear ridge of the femur and were larger than had been indicated by the radiographs. Eight horses were being used for their intended purpose, which was racing (3 horses were racing and 3 were in race training), dressage (1 horse) or pleasure riding (1 horse). One horse required a second surgery when similar lesions developed on the opposite stifle, and was euthanatized 2 months later because of persistent lameness. One clinical signs are observed, osteochondrosis lesions of the distal femur can progress in foals younger than 9 months of age and the full extent of the radiographic lesion may take several weeks to develop.

	Title	A review of regional and temporal use of avermectins in cattle and horses worldwide			Type	Journal Article
	Year	1993	Publication	Veterinary Parasitology	Abbreviated Journal	Vet Parasitol

	Abstract	Ivermectin and abamectin are two members of the group of parasiticides known as the avermectins; ivermectin was first registered as an injectable treatment for cattle in 1981. Since then, abamectin has been registered for cattle and ivermectin for horses. The relative popularity of the avermectins amongst farmers and veterinarians can be attributed to their spectrum of activity, convenience, wide margin of safety and the improved health and performance of stock following their use. Patterns of use in grazing animals apply equally to the avermectins as to other antiparasitics, particularly anthelmintics; these are based on a knowledge of epidemiology integrated with practical management considerations. For cattle, programs are commonly aimed at control of abomasal nematodes of the genera Ostertagia and Haemonchus. Use of avermectins is largely strategic in cattle, treatments being favored at the end of the period of transmission of these parasites; this frequently coincides with housing, entry into a feedlot or movement to another pasture. Simultaneous control of important ectoparasites at this time is an added benefit. Prophylactic use of avermectins at pasture is primarily targeted at the young first season grazing animal. In horses, a bimonthly treatment schedule during the period of risk has proved effective in helping prevent adverse effects of the main target parasites, including large and small strongyles and stomach bots. These patterns of use can be applied to the evaluation of the potential for avermectin residues in feces to have impact on pasture ecology. The evidence presented suggests that any effects are temporally and spatially limited. After more than a decade of practical use, there is no indication that avermectins have had a significant impact on pasture ecology and the environment.
