Virtual Horse Shows: Participants Perspective on a Novel Alternative During COVID-19 Pandemic☆.

The COVID-19 pandemic has increased the availability of virtual horse showing opportunities. The objectives of this study were to describe survey participants' personal characteristics and participation in virtual and in-person horse shows, level of satisfaction, attitude toward technology and motivation to participate, and internal and external factors influencing the decision to participate in virtual horse shows. A survey was distributed to a target audience of adult horse show participants and/or adults supporting youth horse show participants via Qualtrics (n = 251). A majority of respondents (91.2%) reported benefits to participating in virtual horse shows, and 59.8% plan to continue showing virtually when in-person shows resume. The opportunity to show virtually has resulted in 76.1% of respondents anticipating increasing their participation in showing (in-person or virtual). An improvement in attitude toward technology (M =1.6; SD = 0.4; Range = 1.0-2.3) and an increase in motivation to participate, ride and show (M = 1.4; SD = 0.4; Range = 1.0-2.8) was also reported. In addition, respondents indicated they were somewhat likely to be influenced to participate in virtual shows by internal factors such as their budget and ability to record the ride. External factors such as feedback from judges, available divisions, and awards were extremely likely to influence their decision to participate. In conclusion, virtual horse shows have provided a satisfactory outlet to keep people engaged in the industry. Additional research should be done to determine if the current popularity of virtual horse showing persists once in-person shows have fully resumed.

Early Evidence of the Economic Effects of COVID-19 on the Horse Show Industry in 2020.

The COVID-19 pandemic affected the economic status of all sectors of the global economy including the horse show industry. Reporting the impact of COVID-19 on in-person horse shows and an early assessment of its impact on the economy was the objective of this study. A Qualtrics survey instrument was disseminated to horse show participants through social media pages and email (n = 251). A majority of respondents were females (95.6%) representing a cross-section of the United States (84.0%). Participants reported planning to attend an average of 9.7 (SD = 7.15) in-person horse shows in 2020 but were unable to attend an average of 4.17 (SD = 3.11) due to COVID-19 restrictions. Participants reported spending a mean of $991 (SD = $648.26) per show on horse show-related expenses, or $9,609 annually. The American Horse Council (2018) reported that 1,227,986 horses comprise the competition sector, with each horse owner showing 1.57 horses.  This participation generates $7.5B in expenses annually. The reduced attendance at in-person shows resulted in a decrease in annual expenditures, suggesting economic losses of $3.23 billion. The quantified direct effects were used in the IMPLAN input-output model to estimate the total economic impact. The reduced attendance resulted in a reduction of $7.2 billion, and a reduction of approximately 50,000 jobs within the horse show industry. Additionally, the industry's contribution to GDP (value added) was reduced by $3.95 billion. Early assessments of the economic impact associated with a reduction of in-person horse showing is vital to understanding the long-term implications for the industry.

Effects of aquatic conditioning on cartilage and bone metabolism in young horses.

While beneficial in rehabilitation, aquatic exercise effects on cartilage and bone metabolism in young, healthy horses has not been well described. Therefore, 30 Quarter Horse yearlings (343 ± 28 kg; 496 ± 12 d of age) were stratified by age, body weight (BW), and sex and randomly assigned to 1 of 3 treatments for 140-d to evaluate effects of aquatic, dry, or no exercise on bone and cartilage metabolism in young horses transitioning to an advanced workload. Treatments included nonexercise control (CON; n = 10), dry treadmill (DRY; n = 10), or aquatic treadmill exercise (H2O; n = 10; water: 60% wither height, WH). Horses were housed individually (3.6 × 3.6 m) from 0600 to 1800 hours, allowed turnout (74 × 70 m) from 1800 to 0600 hours, and fed to meet or exceed requirements. During phase I (days 0 to 112), DRY and H2O walked on treadmills 30 min/d, 5 d/wk. Phase II (days 113 to 140) transitioned to an advanced workload 5 d/wk. Every 14-d, WH, hip height (HH), and BW were recorded. Left third metacarpal radiographs on days 0, 112, and 140 were analyzed for radiographic bone aluminum equivalence (RBAE). Every 28-d, serum samples were analyzed for osteocalcin and C-telopeptide crosslaps of type I collagen (CTX-1), and synovial fluid samples were analyzed for prostaglandin E2, collagenase cleavage neopeptide (C2C), collagenase of type I and type II collagen, and carboxypeptide of type II collagen using ELISAs. All data were analyzed using PROC MIXED of SAS, including random effect of horse within treatment, and repeated effect of day. Baseline treatment differences were accounted for using a covariate. There were treatment × day interactions (P < 0.01) where OC and CTX-1 remained consistent in both exercise groups while inconsistently increasing in CON. There were no treatment differences (P > 0.30) in RBAE, BW, or HH, but all increased over time (P < 0.01). There were no treatment × day interactions of synovial inflammation or markers of cartilage metabolism; however, there was an effect of day for each marker (P<0.03). Changes in biomarkers of cartilage turnover in horses exercised at the walk, whether dry or aquatic, could not be distinguished from horses with access to turnout alone. This study indicates that early forced exercise supports consistent bone metabolism necessary for uniform growth and bone development, and that there are no negative effects of buoyancy on cartilage metabolism in yearlings transitioned from aquatic exercise to a 28-d advanced workload.

Skeletal response to whole body vibration and dietary calcium and phosphorus in growing pigs.

The quality and strength of the skeleton is regulated by mechanical loading and adequate mineral intake of calcium (Ca) and phosphorus (P). Whole body vibration (WBV) has been shown to elicit adaptive responses in the skeleton, such as increased bone mass and strength. This experiment was designed to determine the effects of WBV and dietary Ca and P on bone microarchitecture and turnover. A total of 26 growing pigs were utilized in a 60-d experiment. Pigs were randomly assigned within group to a 2 × 2 factorial design with dietary Ca and P concentration (low and adequate) as well as WBV. The adequate diet was formulated to meet all nutritional needs according to the NRC recommendations for growing pigs. Low Ca, P diets had 0.16% lower Ca and 0.13% lower P than the adequate diet. Pigs receiving WBV were vibrated 30 min/d, 3 d/wk at a magnitude of 1 to 2 mm and a frequency of 50 Hz. On days 0, 30, and 60, digital radiographs were taken to determine bone mineral content by radiographic bone aluminum equivalency (RBAE) and serum was collected to measure biochemical markers of bone formation (osteocalcin, OC) and bone resorption (carboxy-terminal collagen crosslinks, CTX-I). At day 60, pigs were euthanized and the left third metacarpal bone was excised for detailed analysis by microcomputed tomography (microCT) to measure trabecular microarchitecture and cortical bone geometry. Maximum RBAE values for the medial or lateral cortices were not affected (P > 0.05) by WBV. Pigs fed adequate Ca and P tended (P = 0.10) to have increased RBAE max values for the medial and lateral cortices. WBV pigs had significantly decreased serum CTX-1 concentrations (P = 0.044), whereas animals fed a low Ca and P diet had increased (P < 0.05) OC concentrations. In bone, WBV pigs showed a significantly lower trabecular number (P = 0.002) and increased trabecular separation (P = 0.003), whereas cortical bone parameters were not significantly altered by WBV or diet (P > 0.05). In summary, this study confirmed the normal physiological responses of the skeleton to a low Ca, P diet. Interestingly, although the WBV protocol utilized in this study did not elicit any significant osteogenic response, decreases in CTX-1 in response to WBV may have been an early local adaptive bone response. We interpret these data to suggest that the frequency and amplitude of WBV was likely sufficient to elicit a bone remodeling response, but the duration of the study may not have captured the full extent of an entire bone remodeling cycle.
