Title A review of regional and temporal use of avermectins in cattle and horses worldwide Type Journal Article
Year (up) 1993 Publication Veterinary Parasitology Abbreviated Journal Vet Parasitol
Volume 48 Issue 1-4 Pages 19-28
Keywords Animals; Anthelmintics/therapeutic use; Arthropods; Cattle; Cattle Diseases/drug therapy/*prevention & control; Ectoparasitic Infestations/drug therapy/prevention & control/veterinary; Horse Diseases/drug therapy/*prevention & control; Horses; Insecticides; Ivermectin/*analogs & derivatives/*therapeutic use; Nematode Infections/drug therapy/prevention & control/veterinary; Parasitic Diseases/drug therapy/prevention & control; *Parasitic Diseases, Animal
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.

Title Unravelling the ecology of influenza A virus Type Journal Article
Year (up) 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 Progression of femoropatellar osteochondrosis in nine young horses. Clinical, radiographic and arthroscopic findings Type Journal Article
Year (up) 1993 Publication Veterinary Surgery : VS : the Official Journal of the American College of Veterinary Surgeons Abbreviated Journal Vet Surg
Volume 22 Issue 6 Pages 515-523

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 The molecular weight of therapeutic hyaluronan (sodium hyaluronate): how significant is it? Type Journal Article
Year (up) 1994 Publication The Journal of rheumatology Abbreviated Journal J Rheumatol

Abstract Various molecular weight hyaluronic acid (HA) preparations have been injected into joints for the treatment of human and equine osteoarthritis. A therapeutic advantage has been claimed for commercial products with a molecular weight in the range found in normal synovial fluid (SF), compared to lower molecular weight products. But a correlation between molecular weight and efficacy is not borne out by an analysis of the available literature on clinical results. SF viscosity, HA concentration, HA molecular weight and rate of synthesis in joint disease. It is proposed that the beneficial effect of injected HA in joint disease may be due to pharmacological rather than to physical properties.

Title The prevalence of abnormal behaviours in dressage, eventing and endurance horses in relation to stabling Type Journal Article
Year (up) 1995 Publication The Veterinary record Abbreviated Journal Vet. Rec.
Volume 137 Issue 2 Pages 36-37
Keywords Animal Husbandry/*methods; Animals; *Behavior, Animal; Horse Diseases/*psychology; Horses; *Physical Conditioning, Animal; Prevalence; Questionnaires; *Stereotyped Behavior
Abstract The behaviour of horses competing in different disciplines was studied and the relationship between the time they spent out of the stable and the prevalence of abnormal behaviour was examined. The owners of dressage, eventing and endurance horses were sent a questionnaire and a total of 1101 responses were received, giving data on 1750 horses. The behaviours studied were wood-chewing, weaving, crib-biting/wind-sucking and box-walking. The reported percentage prevalences of abnormal behaviour for the dressage, eventing and endurance horses were 32.5, 30.8 and 19.5, respectively. The relationship between the time spent in the stable and the prevalence of abnormal behaviour was examined by chi 2 tests which showed that there were significant linear trends for the eventing group (P < 0.001) and the dressage group (P < 0.05). It is concluded that the time a horse spends out of the stable is related to the discipline for which it is being trained and in dressage and eventing horses the time spent in a stable is correlated with an increased risk of abnormal behaviour.

Title Radiographic and endoscopic study of horses performing an oral based stereotypy Type Journal Article
Year (up) 1995 Publication Equine veterinary journal Abbreviated Journal Equine Vet J
Volume 27 Issue 2 Pages 92-95
Keywords Animals; Endoscopy/*veterinary; Esophagus/physiopathology/radiography; Female; Fluoroscopy/veterinary; Horse Diseases/physiopathology/*psychology/radiography; Horses; Male; Pharynx/physiopathology/radiography; *Stereotyped Behavior; Video Recording
Abstract There is confusion in the veterinary literature concerning the definition of oral based stereotypies in the horse. This study reports the use of fluoroscopy and endoscopy during cribbiting/wind-sucking in afflicted horses. This permitted observations of movements of the pharyngeal and oesophageal tissues and of the air column within during the stereotypic behaviour. The findings reported show that the sequence of events during crib-biting/wind-sucking is not related to deglutition and that air is not swallowed to the stomach. Transient dilation of the upper oesophagus was recorded and the characteristic noise of wind-sucking coincided with the in-rush of air through the cricopharynx. The oesophageal distension was relieved when the air returned to the pharynx although small quantities passed caudally. It is proposed that the role of contraction of the strap muscles of the neck is to create a pressure gradient in the soft tissues surrounding the oesophagus which provokes movement of air from the pharynx into the oesophagus. The findings suggest that the definitions currently used in the sale of horses are in need of revision.

Title Management factors associated with stereotypic and redirected behaviour in the thoroughbred horse Type Journal Article
Year (up) 1995 Publication Equine veterinary journal Abbreviated Journal Equine Vet J
Volume 27 Issue 2 Pages 86-91
Keywords Animal Husbandry/*methods; Animals; Horse Diseases/psychology/*therapy; Horses; Risk Factors; *Stereotyped Behavior; Time Factors
Abstract A greater knowledge of the effect of management factors is required to investigate the ontogeny of abnormal behaviour in the stabled horse. A postal survey of racehorse (flat) trainers yielded information about 22 yard and management factors. The relationship of the factors to the prevalence of abnormal behaviour was analysed by logistic regression. Management factors related to the time spent in the stable showed the strongest associations with stereotypic behaviour. The risk of horses performing abnormal behaviour increased: 1) as the amount of forage fell below 6.8 kg/day, 2) when bedding types other than straw were used, 3) when the total number of horses on the yard was fewer than 75, 4) in association with box designs that minimised contact between neighbouring horses, 5) when hay, rather than other types of forage, was used.

Title Photic headshaking in the horse: 7 cases Type Journal Article
Year (up) 1995 Publication Equine Veterinary Journal Abbreviated Journal Equine Vet J
Volume 27 Issue 4 Pages 306-311
Keywords Animals; Anti-Allergic Agents/therapeutic use; *Behavior, Animal; Cyproheptadine/therapeutic use; Female; *Head; Horse Diseases/drug therapy/*etiology; Horses; Light/*adverse effects; Male; Movement Disorders/drug therapy/etiology/*veterinary
Abstract Seven horses with headshaking are described. No physical abnormalities were detected in any of the cases. Six of these horses had onset of clinical signs in the spring. The role of light was assessed by application of a blindfold or dark grey lens to the eyes, covering the eyes with a face mask and observing the horse in total darkness outdoors. Cessation of headshaking was observed with blindfolding (5/5 horses), night darkness outdoors (4/4 horses) and use of grey lenses (2/3 horses). Outdoor behaviour suggested efforts to avoid light in 4/4 cases. The photic sneeze in man is suggested as a putative mechanism for equine headshaking. Five of 7 horses had improvement with cyproheptadine treatment (0.3 mg/kg bwt b.i.d.). Headshaking developed within 2 calendar weeks of the same date for 3 consecutive years in one horse. Neuropharmacological alterations associated with photoperiod mechanisms leading to optic trigeminal summation are suggested as possible reasons for spring onset of headshaking.
