[Brainstem auditory evoked responses in horses with hearing loss and during general anesthesia]. The brainstem auditory evoked response (BAER) is a diagnostic approach to examine the hearing system of horses objectively. The aim of this BAER examination was the diagnosis of conductive or sensorineural hearing loss or deafness in horses with external otitis, head trauma, headshaking, tinnitus or skittish horses with eye disease. Brainstem dysfunction is induced by intracranial hypotension. BAER was used in horses with colic surgery which had a low arterial blood pressure during general anesthesia. The endoscopic finding of the guttural pouch was the ipsilateral mild to severe hypertrophy o...

The aim of this retrospective study is to describe and compare conservative and surgical treatment of navicular fractures in horses. An attempt is made to identify critical points that can favorably influence the prognosis of this orthopedic disease. All horses treated for a navicular fracture at the Equine Clinic, Vetsuisse Faculty, University of Zurich between 2005 and 2017 were included in this study. The severity of lameness at initial examination, radiographic assessment, hoof conformation, treatment (conservative or surgical), complications and outcome were determined from the medical re...
[DDB2-associated incidence of squamous cell carcinoma in Haflingers: risk minimization by genotyping]. SCC (squamous cell carinomas) are among the most common eye neoplasms in horses. In recent studies Haflinger horses with a homozygous genotype for a missense variant in the DDB2 gene (damage specific DNA binding protein 2) had a significant increased risk of developing ocular SCC. The aims of this study were to determine the frequency of the SCC-associated risk allele in the DDB2 gene in Swiss and Austrian Haflinger populations and to validate the previously described phenotypic correlation. For this purpose, Haflingers presented at various horse clinics in Switzerland (n = 21, including 1...

This study aimed to determine the effectiveness of parentage verification in Arabian and Thoroughbred horses in Türkiye using microsatellite markers. A total of 813 Arabian and 959 Thoroughbred horses were genotyped using a total of 17 microsatellite markers. The mean effective number of alleles was 3,34 and the mean number of alleles was 7,41 in Arabian horses. It was calculated that the mean He and Ho values in Arabian horses were 0,677 and 0,680, respectively. The mean effective number of alleles was 3,55 and the mean number of alleles was 6,59 in Thoroughbred horses. It was calculated tha...
[Ocular and non-ocular squamous cell carcinomas in the Haflinger: Eight cases at the Institut Suisse de Médecine Equine (2015-2022)]. This case series describes the clinical course of ocular and non-ocular squamous cell carinoma (SCC) in the Haflinger horse and is intended to raise awareness of the high recurrence rate and tendency to metastasize. Eight Haflingers with histologically confirmed SCC were included, five ocular and three non-ocular, who were presented at the Institut Suisse de Médecine Équine (ISME) Bern between July 2015 and January 2022. The ocular SCC cases were all presented because of an apparent mass, which in most cases was post-treatment recurrence. The occurrence of recurrences was observed between 3 ...
The prevalence of equine odontoclastic tooth resorption and hypercementosis and the role of interincisal angulation in disease severity in a representative cohort of horses in Switzerland. Equine odontoclastic tooth resorption and hypercementosis (EOTRH) is an increasingly diagnosed degenerative dental disease in aged horses. The primary aim of this retrospective study was to determine the prevalence of EOTRH in horses admitted to the Equine Hospital, University of Zurich, for dental procedures from 2004 to 2017. A secondary goal was to measure and compare interincisal angles on two-dimensional radiographs of horses with EOTRH to determine whether the interincisal angle is associated with age and severity of the disease. Radiographs were assessed for the presence of lysis and/or...
Survey of horse transportation in Switzerland: practices and issues. This study aimed to describe equine transportation practices and transport-related behavioural and health problems in Switzerland and to identify possible associations between them. An online survey was disseminated to Swiss equine industry members and questioned respondents' details, transport practices (before, during, and after journeys), horse transport-related behavioural (TRPBs) and health problems (TRHPs) experienced in the previous 2 years. The survey generated 441 valid responses, analysed using descriptive statistics and logistic regression models (outcomes: TRPBs, TRHPs, injuries, d...
[Heart rate and faecal cortisol metabolites measurements in horses at the Sechseläuten in Zurich]. The Zurich's Sechseläuten is a traditional festival of the Zurich guilds, in which around 500 horses take part. After a parade through the old town of Zurich, the riders gather at a big square to canter around a burning woodpile topped with an exploding effigy (the «Böögg»). The level of stress experienced by the horses partaking in this event is subjected to increasing scrutiny. The aim of this study was to evaluate the stress load of the horses participating in the Sechseläuten procession more objectively by measuring heart rate and faecal cortisol metabolites. Twenty-three horse-rider...
[Glyphosate detection in the duodenal fluid of horses with gastric ulcer syndrome]. The hay producing plants, concentrate, straw and meadows could be contaminated by the aerosols of glyphosate based herbicide during spraying process of crops and pre-harvest desiccation treatment of cereals. The aim of this study is to investigate the concentration of glyphosate in the duodenal fluid of horses with gastric ulcer syndrome. The stomach and duodenum of referred untreated horse patients (n=92) with colic, weight loss, diarrhoea, anemia or performance intolerance were endoscopically examined right after the admission. Duodenal fluid (40 ml) was collected from the duodenal region ...
[Is alfalfa hay an alternative to meadow hay in equine nutrition?]. Roughage alternatives for equine nutrition must be found due to the increasing climatic challenges. The aim of this study was to examine the nutrient composition and feed hygiene of alfalfa hay in comparison to meadow hay and to investigate the acceptance, weight development and faecal quality of broodmares fed alfalfa hay. The feed used was examined for nutrient content and hygiene status according to the standards of the Verband Deutscher Landwirtschaftlicher Untersuchungs- und Forschungsanstalten (VDLUFA). Twenty adult pregnant warmblood mares were fed in two groups (n=10) with a defined am...
Characterization of an outbreak of equine coronavirus infection in adult horses in Switzerland. Outbreaks of equine coronavirus (ECoV) infections have been described in different parts of the world including Europe. The aim of this report was to describe clinical signs, diagnostic work-up and outcome of the first documented outbreak of ECoV in Switzerland in order to raise the awareness for the disease and its various clinical presentations. The outbreak occurred on a farm with 26 horses. Of these, seven horses developed clinical disease ranging from mild signs such as fever and anorexia to severe signs of acute colitis. One horse died due to severe endotoxemia and circulatory shock seco...
Prevalence and whole genome-based phylogenetic, virulence and antibiotic -resistance characteristics of nasal -Staphylococcus aureus in healthy Swiss horses. A total of 100 nasal swabs were collected from healthy horses in Switzerland between January 2020 and August 2020. The samples were taken from horses at 40 different stables in 12 different cantons and screened for both methicillin-resistant (MRSA) and methicillin-susceptible S. aureus (MSSA) using selective agar plates. S. aureus were tested for antibiotic susceptibility by measurement of the minimal inhibitory concentration (MIC) and for virulence factors, antibiotic resistance genes and phylogenetic characteristics using whole genome sequence analysis. Ten horses were found to be positiv...
Helminths and their management in Swiss Army horses: differences between riding horses and pack horses evidence the need of improvement. Intestinal helminth management in horses has both clinical and epidemiologic relevance, in additional association with anthelmintic resistance. The Swiss Army employs military owned riding horses and privately owned pack horses, which are brought together for service periods up to 12 weeks. We compared husbandry conditions and intestinal helminth management of both groups via questionnaire and analysed faecal samples of 53 riding horses and 130 pack horses using combined sedimentation/flotation, the McMaster method and larval cultures. Riding horses only had cyathostomin infections (prevalence...
Owner reported clinical signs and -treatment decisions in equine pastern dermatitis. Equine pastern dermatitis has a high prevalence in the equine population, especially in draft breeds. This skin condition is difficult to treat, and it is suspected that owners often decide on a treatment without consulting a veterinarian. The objectives of this study were to describe owner-reported clinical signs, severity, and reasons to consult a veterinarian. Moreover, we inquired about preventive measures and treatments, both instituted by owners without previous consultation or prescribed by their veterinarians. A total of 123 horses (owners recruited over social media) were included in ...
[Equine anaplasmosis and equine piroplasmosis in Germany, Austria and Switzerland – previously anecdotal, now relevant?]. Equine granulocytic anaplasmosis (EGA) and equine piroplasmosis (EP) are triggered by tick-borne pathogens - the intracellular bacterium Anaplasma phagocytophilum and the intracellular protozoa Babesia caballi and Theileria equi. These pathogens attack cells in the blood stream and cause similar clinical symptoms and changes in laboratory values. Although the treatment principles are naturally different, similarities in prophylaxis exists due to the transmission route. Tick transmitted pathogens can play a greater role in equine medicine in the future due to various factors, such as the tenden...
[Vaccinovigilance: Adverse reaction reports of animal vaccines in 2020]. The aim of the vigilance system in Switzerland is the evaluation and classification of reported suspected adverse reactions of immunological veterinary medicines (IVMP), including suspected lack of expected efficacy. The Institute of Virology and Immunology (IVI) is the competent authority for marketing authorizations of immunological veterinary medicinal products in Switzerland and responsible for the vaccinovigilance system. In 2020, 130 adverse reaction reports were received (5% less compared to 2019). The reports mainly concerned dogs (41%) and cats (25%) followed by cattle (18%) and horse...
[Prevalence of health problems in midlife Swiss warm-blooded horses]. The breeding of a healthy horse is the basic requirement for optimal performance. This is also specifically stated in the breeding goal of the Swiss warmblood horse and should be achieved through a strict selection of the stallions. The aim of this retrospective study was to assess the current state of the population to optimize breeding. Data on the health status of Swiss warmblood horses in the age between 6 and 16 years (midlife) were collected by a telephone survey and analyzed descriptively. Following the heritability of the most common health problems were estimated. Data on 1,861 horses...

The aim of the present retrospective study was the evaluation of the rescue protocols of the GTRD CH/FL from such operations and the documentation of a rescue procedure. In the past 25 years, a total of 176 animals have been rescued from manure and cesspools. These included 113 cattle, 51 horses and 12 pigs. All animals could be safely rescued with the animal rescue and transport net (TBTN) or the large animal vertical rescue set (GTVBS)....
Age over 25 years, but not plasma adrenocorticotropic hormone con-cen-tration above the seasonally adjusted reference range is predictive for radio-graphically assessed changes of chronic laminitis in elderly horses. Endocrinopathic laminitis occurs as a consequence of hormonal derangements like pituitary pars intermedia dysfunction (PPID). The objective of the present study was to assess the occurrence of radiographic changes associated with chronic laminitis in elderly, clinically sound horses. Fifty-one horses were included in the study. Horses were assigned to different age groups, in groups according to their BCS and CNS as well as to groups with different ACTH concentrations in order to assess their risk of chronic laminitis (reported as odds ratios (OR) and confidence intervals (CI)). Horses assigne...

[Professional entry into equine medicine]. In the present study phone interviews on working hours, salary, professional satisfaction and other topics were carried out with 30 equine veterinarians. None of the participants had more than five years of work experience. The gross annual wages ranged from CHF 36'400 to CHF 91'500. The study participants worked 42 to 93 hours per week. Only 13% were moderately satisfied with the job, the remaining participants were satisfied to highly satisfied. Sixty percent of the study participants were dissatisfied with their wages and wished to be paid according to the Swiss Veterinary Association (GST...
[Colonel Hermann Schwyter, equine surgeon, a formative personality of equine medicine]. The biography of Colonel Hermann Schwyter, equine surgeon of the Swiss Army from 1928 to 1937, and the history of training of farriers in Switzerland since the 18th century are presented. Hermann Schwyters dissertation examined the changes of equine hoof confirmation as a result of standing and gait in approximately 2,000 horses and numerous anatomical specimens. He defines the foot placement, describes possible variations, their causes and effects. Significant is also his study of the compression pathology in horses and mules. His recommendations are still valid today. The present article ref...
[Equine Infectious Anaemia – a review from an official veterinary perspective]. Equine infectious anaemia (EIA) is a sporadic viral disease in many countries. Every single case has, however, a dramatic impact: infected animals have to be put down, and quarantine restrictions on horse movements lasting three months lead to substantial economic losses. In Switzerland, the mandatory notification was introduced in 1994 in order to facilitate international traffic. A year later, the "new" Ordinance on epizootics of 1995 classified EIA as a "disease to be eradicated". An infected polo horse in the canton of Argovia in summer 2017 thus represented Switzerland's first official ca...
Relationships between antral follicle count, blood serum concentration of anti-Müllerian hormone and fertility in mares. The anti-Müllerian hormone (AMH) plays an inhibitory role during folliculogenesis by regulating the number of follicles entering the growing pool. Antral follicle counts (AFC) are highly correlated with serum AMH concentrations and both appear to be related to the ovarian reserve in several species. Few data on AMH and AFC in mares exist, especially with regard to fertility. Therefore, the objective of the current study was to investigate the interrelationship between antral follicle count, serum AMH concentrations and fertility outcome in mares. One hundred and twenty-seven mares were enroll...
[Ethics in Swiss equestrian sports: Is animal welfare adequately implemented?]. Animal welfare in equestrian sports is a very current and important topic for animal right groups as well as for the Swiss association for equestrian sports "Schweizerischer Verband für Pferdesport (SVPS)". The penalty commission "Sanktionskomission (SAKO)" of the SVPS reported only few to none cases of infringements of animal welfare provision on horses at a time in the past few years. This fact was criticised several times by different animal right groups in Switzerland. Therefore a survey was sent in 2017 to 544 active officials (horse show judges) of the SVPS. Overall, 146 answered questi...
[Quality Assessment of Bovine and Equine Colostrum – An Overview]. Good quality colostrum intake is essential for passive immunity in neonatal calf and foals. The quality of colostrum depends on its IgG content. Since in practice the possibilities for a direct determination of these parameter are limited, an estimation of colostrum quality is often based on its biophysical properties. The simple methodology allows to perform measurements directly on site and immediately after birth. The biophysical properties included in the current review are density, refractive index, relative density, viscosity, pH, and color. The determination of the density of bovine col...
[Vaccinovigilance: Reported adverse reactions of immunological veterinary medicinal products in 2018]. The registration of adverse events after the use of immunological veterinary medicinal products (VMP) is the aim of the vaccinovigilance reporting system in Switzerland. Adverse events comprise suspected adverse reactions and lack of expected efficacy. Since the Institute of virology and immunology (IVI) is the competent authority for the regulation of immunological VMP in Switzerland, the reporting system is administrated by the IVI. In 2018, 162 reports concerning authorized immunological VMP were received. While most of the reports were submitted by the marketing authorization holders (79%)...
[Vigilance for veterinary medicinal products: Reports of adverse reactions in the year 2017]. A total of 306 reports of adverse reactions to veterinary medicinal products were received during the year 2017 representing an increase of 21% compared to the previous year. The majority of these reports described reactions concerning companion animals (180 dogs and 59 cats) as well as cattle (38 reports) and horses (14 reports). Most of the reported reactions were linked to the use of antiparasitics (158 reports), hormone products (30 reports) and anti-inflammatory products (25 reports). 40 reports were generated from consultations with Tox Info Suisse in Zürich and mainly involved the ex...
