Two-year-old racehorse fatalities attributed to pandemic disruption


Delegates at a seminar on racehorse health and welfare have heard that fatalities among two-year-old thoroughbreds  spiked in 2020, against a 31.5% drop in overall racehorse fatalities since 2009.

Reviewing findings of the Equine Injury Database (EID) since its inception in 2009, Dr Tim Parkin told the 10th Welfare and Safety of the Racehorse Summit in Kentucky that the trend for two-year-old fatalities may have been caused by disruptions in training at the height of the Covid-19 pandemic.

Parkin, who is head of Bristol Veterinary School, also compared changes in risk for horses who compete on multiple surfaces versus those who race on one surface. Furthermore, he pointed out that sudden deaths have become a larger proportion of all fatalities since the advent of the EID as the decreasing rate of musculoskeletal injuries has outpaced the decline in sudden death rates.

Following Parkin’s presentation, Dr Larry Bramlage of Rood & Riddle Equine Hospital discussed the importance of training two-year-olds. He said bones are dynamic organs that strengthen and remodel in response to exercise.

“Bone trains to the level of work, not the amount. The cardiovascular system trains to the amount of work,” Bramlage said. “The limiting system is always the skeleton in the horse.”

Given this knowledge and the aforementioned spike in two-year-old fatalities in 2020, Bramlage believes that two-year-olds racing that year may have been kept in a holding pattern in terms of intense training due to the uncertainty of race dates. Consequently, the development of their cardiovascular systems outpaced their skeletal systems.

Dr Dionne Benson, chief veterinary officer of 1/ST Racing (Stronach Group), talked about the changes implemented at its tracks following the highly publicised rash of breakdowns at Santa Anita Park in 2019. Among the protocols are an increased veterinary presence at the tracks, stricter medication rules during racing and training, additional monitoring on race day, out-of-competition testing, and required registration of a horse before participating in a timed workout. Santa Anita recently completed the safest Winter/Spring meet on record, showing a 74% improvement since the spring of 2019.

“We have changed to a culture of safety out there,” Benson said. “There is a conscious effort to put the horse first.”

Dr Ryan Carpenter, a surgeon at Equine Medical Center in California, described a program whereby racehorses that suffer complex musculoskeletal injuries on the track are given the opportunity to undergo surgery to repair their fractures if there is a favorable prognosis for them to ultimately become pasture-sound.

Dr Mathieu Spriet, professor of diagnostic imaging at University of California, Davis, presented findings from the use of positron emission tomography (PET) to evaluate fetlocks. In 2019, California installed a standing PET machine that can scan all four limbs in under 20 minutes without the use of anesthesia. The data demonstrated the efficacy of this technology for monitoring horses for injury and tracking healing.

Dr Wayne McIlwraith, founding director of the Orthopaedic Research Center at Colorado State University, talked about the history of surface testing and the Racing Surfaces Testing Laboratory. Key factors in a safe racetrack are consistency, proper moisture content, and temperature. With the Horseracing Integrity and Safety Act (HISA) set to go into effect next month, racetracks will be required to have data protocols and standardized testing methods in place.

Dr Jerry Hill, chief medical adviser for the British Horseracing Authority (BHA), detailed a strategy by the BHA to improve the physical and mental wellbeing of jockeys by raising weights, prioritizing nutrition, and revamping areas at the racetracks that are dedicated to riders on race day.

Data mining and wearable tech

The summit also heard about wearable technologies for horses in a panel moderated by New York Thoroughbred Horsemen’s Association president Joseph Appelbaum. Valentin Rapin, managing director and co-founder of Arioneo, described his company’s sensors that horses can wear during training that track metrics such as heart rate. Will Duff Gordon, the chief executive officer of Total Performance Data (TPD), talked about his company’s tracking technology and the potential benefits to gamblers. Equibase is currently working with TPD to harness this data and acknowledged the challenge of making this technology scalable.

“The last few years have been about acquiring the data, getting onto as many racecourses as possible, having a big enough data set. The present and the future is about mining that data,” Gordon said.

Dr Scott Palmer, equine medical director of the New York State Gaming Commission, reviewed findings from a case study using StrideSAFE, a device that detects abnormalities in a horse’s gait and may have use in the future for detecting injuries before visible lameness develops. He sees great potential in the data from these technologies, especially with the imminent implementation of the Horseracing Integrity and Safety Act (HISA), which goes into effect on July 1.

“I think that the introduction of HISA is going to make a huge change. They’re already requiring a lot of data, and it seems to me that right now the challenge is going to be to prioritize,” he said. “Having sensors on horses while they train and while they race is going to be important.”

The summit on June 22 concluded with presentations from Chris Dobbins, senior vice-president of InCompass, the Jockey Club’s technology solutions company, and Dr Stuart Brown, vice-president of equine safety at Keeneland. Dobbins summarized the programs that InCompass offers to tracks to assist them in collecting and organizing data that is used to promote safety and welfare, including current efforts to facilitate record keeping once HISA goes into effect. Brown reviewed Keeneland’s safety protocols and how InCompass software provides Brown with important data for flagging horses that are at increased risk of injury.

The summit was run in an in-person format for the first time since 2018, and was co-hosted by the Jockey Club and Grayson-Jockey Club Research Foundation and open to the public. It was emceed by Annise Montplaisir, equine education coordinator of the Kentucky Equine Education Project Foundation and president of Amplify Horse Racing.

Montplaisir also moderated a youth panel of individuals working in the Thoroughbred industry or pursuing a career in the industry: Hayley Amoss, manager, communications and social media, Breeders’ Cup; Hallie Hardy, executive director, Horse Country; Dr Ferrin Peterson, jockey and veterinarian; Eric Resendiz, student at Bluegrass Community & Technical College and former Amplify Horse Racing mentee; and Deja Robinson, pre-vet student.

There was shared sentiment among the youth panel that participants in the Thoroughbred industry must take the time to educate those who are unfamiliar with the industry so that they develop a positive impression. They highlighted the impact of connecting with people on a personal level, either in person or through social media.

Grayson president Jamie Haydon said the information shared at the summit demonstrated how the Thoroughbred industry can come together to make meaningful positive changes.

“It is clear that collecting and utilizing comprehensive data is key to maximizing the safety of our human and equine athletes. We are thankful to Keeneland for enabling us to host this event and to our speakers for sharing their wealth of knowledge for the benefit of our industry.”
