Limited research has assessed the “human dimension” of horse care. The aims of this study were to (1) understand horse owner attitudes toward horse welfare when kept outdoors versus indoors and in groups versus individually, (2) compare horse owner attitudes toward horse welfare with the ways in which they house their horses, and (3) explore horse owner reasons for and challenges with their horses’ housing. Seventy-six horse owners in Prince Edward Island, Canada completed a questionnaire. Non-parametric tests and quantitative content analysis were used for data analysis. Consistent with the way horses were kept, most (82–96%) owners agreed that horses’ physical health, mental well-being, and natural living were better when kept outdoors and in groups. Fewer (64–68%) participants agreed that the horses’ standard of care was better when kept outdoors or in groups. Results show associations between owners whose attitudes suggest indoor and/or individual housing is better for horse welfare and keeping their horses indoors part-time and/or individually. Two overarching themes were developed from owners’ responses regarding their reasons and challenges related to the ways in which horses were housed: horse-centered and owner-centered care. The results indicate that horse owners’ choices about their horses’ housing correspond to beliefs about improved horse welfare.
Summary
The heart rate changes during routine training in a group of 8 actively racing Standardbreds were used to simulate the training work on a treadmill (ST) and indices of exercise compared to maximal effort (MAX) on the treadmill. The following parameters were recorded during treadmill work: heart rate, velocity, O2 consumption, respiratory and stride frequency, and stride length. Blood lactate concentrations were measured before and after each work test.
Heart rate during simulated training was mean ± s.d. 87.8 ± 5.5% heart rate in MAX, one of the 8 horses working <80% of maximal HR and 2 of the 8 horses working above 90% maximal heart rate. Mean ± s.d. oxygen consumption during the ST was 75.1% ± 8.4% MAX, but correlated poorly against percentage heart rate for individual horses (r2 = 0.02). At similar velocities for the ST and MAX, only respiratory frequency differed significantly (P>0.05), being higher during the ST.
Most horses worked at intensities based on heart rate consistent with proposed guidelines of 80–90% of maximal heart rate. However, in 3 of the 8 horses work intensity of insufficient or excessive amounts may have occurred.
Summary
A 6‐month‐old Standardbred weanling presented with acute non‐ambulatory tetraparesis. Cranial nerve examination was normal and neuroanatomic localisation suggested there was a focal C1‐C5 spinal cord lesion. Post‐mortem examination identified a cervical vertebral epidural haematoma at the level of C2‐C3 causing spinal cord compression and neurological deficits. Histological examination determined the haematoma was several weeks old making the lesion chronic. Since the clinical progression was acute, this suggests an acute on chronic pathophysiology. Even with no history of trauma, an epidural haematoma should be on the differential list in young horses with acute tetraparesis.
A 3-year-old Standardbred trotting gelding presented to the Atlantic Veterinary College for diagnostic work-up of poor performance and abnormal respiratory noise during exercise. Physical examination was unremarkable, and no significant findings were identified on standing endoscopic examination of the upper respiratory tract. Treadmill endoscopy was utilised for dynamic evaluation of the upper respiratory tract; a diagnosis of epiglottic retroversion was confirmed. The owner requested euthanasia of the gelding, and a postmortem evaluation was completed. Despite thorough gross and histological examination of the head and neck on postmortem examination, no evidence was identified to support the postulated aetiologies for epiglottic retroversion currently found in the literature. This case represents the first reported findings from a post-mortem examination of a horse with epiglottic retroversion.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
