Summary Reasons for performing study: Perennial ryegrass staggers is purported to be a common neurological mycotoxicosis of horses but the case description lacks detail and evidence. Objective: To describe the clinical syndrome of lolitrem B intoxication in horses, limiting tests to those that are applicable to clinical practice, and to assess the potential value of enzyme‐linked immunosorbent assay (ELISA) tests for lolitrem B in horse body fluids. Methods: Seven horses in 2 separate groups were fed perennial ryegrass seed and hay containing 2 ppm lolitrem B. Paired data were collected prior to and after 2 weeks exposure to lolitrem B, including video‐documented neurological examination and clinical examination. Results: All horses developed a variable degree of tremor and ataxia when exposed to lolitrem B. Tremor depended on the level of activity and included a subtle, rapid tremor of the eyeball. Ataxia was exaggerated by blindfolding and primarily involved a truncal sway and irregular, but predictable, limb placements. No change was detected in urine lolitrem B levels and, although plasma lolitrem B increased during the treatment period, levels did not correlate with the severity of clinical signs displayed. Limb swelling, heel lesions and serous nasal discharge were also observed in horses most severely intoxicated. Conclusions: The clinical effects of lolitrem B intoxication in horses primarily involve action‐related tremors and symmetrical vestibular ataxia. Ergovaline may have caused the limb swelling, heel lesions and serous nasal discharge. Plasma ELISA for lolitrem B may be of diagnostic use in the future. Potential relevance: This study provides a clearer appreciation of the clinical signs and variability of perennial ryegrass intoxication in horses.

Abstract Background Reliable lameness thresholds for vertical head displacement for trotting on a circular path and on different surfaces have yet to be defined. Withers movement in lame horses could help improve the diagnostic accuracy of sensor technology. Objectives To define head movement lameness threshold ranges and describe the relationship between head and withers movement during trotting under different circumstances in sound and forelimb lame horses. Study design Retrospective analysis of clinical data and comparison with control group. Methods Fifty‐five sound and thirty‐four naturally lame horses were trotted under field conditions on a hard surface on a straight line and on both directions on soft and hard surfaces. Movement asymmetry was analysed by measuring differences in displacement minima for head and withers using an inertial measurement unit sensor‐based gait analysis system. Receiver operating characteristic (ROC) analysis was performed to define threshold ranges. Relationships between head and withers data were identified by calculating the correlation with linear regression analysis. Results Estimated lameness threshold values for vertical head movement asymmetry ranged from 11.5 to 12.5 mm. On both surfaces, a head movement asymmetry threshold range from 24.5 to 26.5 mm could be found for the circle. Lame horses showed significant correlations between head and withers movement on hard ground straight line ( R 2 0.714, p &lt; 0.001) and inner leg lame horses on the lunge ( R 2 0.915, p &lt; 0.001). Main limitations Different sources of lameness were not distinguished. Radius and speed during lungeing could not be perfectly controlled. Inclusion in the sound group was based on a subjective examination by one clinician and in the lame group two clinicians subjectively determined inner and outer leg lameness creating an extra amount of uncertainty. Conclusions Lameness thresholds for quantifying head movement asymmetry on the lunge were proposed. A significant correlation was observed between head and withers movement asymmetry under several conditions.

Abstract Background A proportion of senior horses (≥15 years of age) are still used for competition. Information about this particular group of horses is currently sparse. Objectives To provide an overview of the demographics, management and health of competing U.S. senior horses (≥15 years of age). Study design Online survey. Methods Descriptive and inferential (Kruskal–Wallis test) analysis of 246 surveys from owners of U.S.‐resident senior horses used for competition. Confidence intervals were calculated for prevalence estimates of clinical signs and medical conditions. Results Competing senior horses were mainly kept at their owners' own facility, with owners making all management decisions (52.2%). In terms of housing, competing senior horses were most frequently kept in a stall but with ≥12 h a day on pasture. Competing seniors were predominantly 15–20 years of age (73.4%), were geldings (69.5%) and were Quarter Horses (33.5%). About one‐half competed/trained for competition at a medium level. Three percent competed at the highest (e.g., international) level. The most common discipline was dressage (32.0%). Stiffness/reduced leg‐joint flexibility was the most common owner‐reported clinical sign (29.2%; 95% CI: 23.5–35.6) and osteoarthritis was the most common owner‐reported veterinary‐diagnosed medical condition (32.6%; 95% CI: 26.8–39.0), followed by gastric ulcers (8.0%; 95% CI: 5.1–12.3) and lameness (7.6%; 95% CI: 4.8–11.8). Nearly one‐half (43.3%) indicated that their competing senior horse had no veterinary‐diagnosed medical condition at the time of the survey. Main limitations Potential recall, response and sampling bias. Conclusions Although few horses over 20 years of age were used in competition, senior horses (≥15 years of age) competed up to the highest level (e.g., internationally) in some disciplines. Competing senior horses were affected by medical conditions commonly reported in the general senior horse population (e.g., osteoarthritis and lameness) and younger competing horses (e.g., gastric ulcers and lameness), potentially increasing the complexity of their management.

Abstract Background Warmblood horses are a popular breed around the world for equestrian sports. Previous studies have investigated ocular findings in other breeds of horses; however, no studies exist for the Warmblood breed. Objectives To determine the prevalence of ocular abnormalities in a convenience sample of Warmblood horses in South Africa and to determine if the prevalence of lens and chorioretinal lesions increase with age. Study design Descriptive, observational study. Methods Warmblood horses underwent a full ophthalmic examination which included a Schirmer tear test (STT), tonometry, fluorescein dye testing, slit lamp biomicroscopy and indirect ophthalmoscopy. Age was categorised into three groups namely &lt;8 years old, 8–13 years old and 14+ years old for statistical analysis. Prevalence of lens and chorioretinal lesions were compared between age categories. Results One hundred and four horses (208 eyes) were examined. The age range was 5 months to 30 years (mean 11 years, standard deviation [SD] 6 years). Ocular pathology was noted in 125 eyes (60.1%) and 79 horses (76%). The highest number of lesions were noted in the choroid and retina, iris and lens. Chorioretinal lesions were seen in 100 eyes (48.1%) and in 65 horses (62.5%). Iridial lesions were seen in 19 eyes (9.1%) and 12 horses (11.5%). Cataracts were seen in 19 eyes (9.1%) and in 13 horses (12.5%). The presence of total chorioretinal lesions (eye level [ p = 0.002]; horse level [ p = 0.004]), focal chorioretinal lesions (eye level [ p = 0.004]; horse level [ p = 0.008]) and cataract (eye [ p = 0.03]; horse level [ p = 0.02]) were all shown to statistically increase with age. Main limitations A small sample size and limited geographic area. Conclusions There was a high prevalence of ocular pathology in this population of Warmblood horses in South Africa. This reiterates the importance of an ocular examination as a part of routine health checks, as well as during prepurchase examinations.

Abstract Background While previous reports come mostly from the southern Americas, several outbreaks of hypersalivation in horses were observed in Middle Europe from 2016 to 2018. Objective To describe feed‐induced hypersalivation in European horses. Study design Analysis of feedstuffs. Methods Veterinarians and horse or stable owners were encouraged to submit feedstuffs from case outbreaks of hypersalivation in which, infectious diseases or other systemic causes of the syndrome were ruled out and intoxication was suspected. Feedstuff analysis was performed, including gross examination, microscopic analysis of fine particles, and for hay and forage mycological culturing and mycotoxin testing. Results Eleven case outbreaks were investigated. Typical clinical findings in the horses were either foamy saliva around the mouth or serous salivation with puddles forming on the ground. Some horses also showed lesions of the gingival mucosa and/or the tongue. Foamy hypersalivation, sometimes combined with lesions of tongue and/or gingiva, was associated with finding of ergot sclerotia and ergot alkaloids in hay or pasture plants (ergocornin and ergocorninin having the highest concentrations). Serous hypersalivation with massive loss of fluid was associated with the fungus Rhizoctonia spp. As indicated by the detection of traces of swainsonine, mycotoxin production on the forage was seen as likely cause. The cessation of clinical signs took days to weeks after diet change, probably depending on the duration, type and amount of toxin intake. Main limitations Small number of case outbreaks, records of clinical findings and horses' management were incomplete and were reported by horse owners. Conclusion Hypersalivation due to mycotoxins in the feed has become an emerging problem for horses in middle Europe.

Abstract Background Fragile foal syndrome (FFS) or warmblood FFS Type 1 (WFFS) is a recessive, autosomal, hereditary, genetic defect causing late abortions, stillbirths and non‐viable foals. Whether early pregnancy losses occur is unknown. Objectives To investigate how WFFS affects pregnancies and whether early pregnancy losses occur in WFFS matings and if there is a difference in pregnancy success between matings where both parents were allele carriers and those where only mare or stallion were WFFS carriers. Study design Retrospective cohort study. Methods Breeding records from a Warmblood stud farm were evaluated (2016–2019) and 2682 cycles of 177 mares analysed. Matings were assigned to four study groups, depending on the WFFS carrier status of the mare and stallion: N/WFFS × N/WFFS ( n = 46), N/WFFS (mares) × N/N ( n = 511), N/N × N/WFFS (stallions) ( n = 191) and N/N × N/N ( n = 2149). Results There were no differences in pregnancy rates between matings with only one WFFS carrier and those with non‐carriers. When comparing N/WFFS × N/WFFS matings to those with only one or no WFFS‐carrier, there were no increased pregnancy losses in the embryonic phase (day &lt;42). By contrast, the N/WFFS × N/WFFS group had significantly more abortions (53.8%) than the other three study groups (7.9–9.2%; adjusted p &lt; 0.0001). The higher losses were evenly distributed between the early (D42–150: 22.7% losses, n = 5) and late (D150–300: 29.4% losses, n = 5) foetal phase. The live foal rate per pregnancy for N/WFFS × N/WFFS matings was lowest (34.5%) and differed significantly (other groups 81%–84%; adjusted p &lt; 0.0001); the peri‐ and postnatal mortality was higher (25%) compared with the other study groups (2.6%–3%). Main limitations Low sample size in N/WWFS × N/WFFS matings, unbalanced study design, outcomes are descriptive, all mares from one stud farm. Conclusions The mating of two WFFS carriers may lead to increased risks of pregnancy and foal loss.
