Australian Study: Why Do Thoroughbreds Retire?

A new study out of Australia has found that 17 percent of 37,750 racehorses retired during the 2017-18 racing season there left the track because of poor performance or at their owner's request. In addition, the study found that 2.1 percent of racehorses that left racing during that timeframe died.

Dr. Kshitiz Shrestha of the University of Melbourne and a research team emailed a questionnaire to the last registered trainers of a sample of the 2,509 Thoroughbreds listed as “inactive” in that timeframe. An “inactive” horse is one that has not worked or raced in the last six months of the racing season, or those horses that were recorded as inactive by Racing Australia.

In total, 1,750 responses were received. Of those, 43 percent had only temporarily left racing; those horses raced the following year. One-third of the retirements were because of injuries, predominantly tendon or ligament issues.

The study determined that the median age of the 780 horses that were retired was 5 years. Females were 1.2 times more likely to be retired than males, but male horses were more likely to become riding horses than females, many of which went on to breed.

The scientists also found that 90 of the 96 horses that died did so because of injury or illness; 54 percent of the horses had experienced an injury while exercising — 24 of them while racing and 19 while training. The other 6 were injured while participating in a trial.

The researchers note that their findings are consistent with previous Australian and New Zealand studies that report that most racehorse retirements are voluntary in nature because of poor performance or owner request.

They note that the decision to retire is based on an accumulation of factors, including performance. The median age of retirement shows that most horses are not forced to retire because of an injury. This information can be used as a benchmark to evaluate programs designed to track Thoroughbreds as they leave racing.

Asymmetrical Movement Common In Young Standardbreds

Scientists from the Norwegian University of Life Sciences and the Swedish University of Agricultural Sciences found asymmetrical movement in most of the Standardbred horses used in a study.

The group recruited the help of 12 Standardbred trainers across Norway and Sweden. They used wireless inertial sensors to detect uneven movement at the trot on 103 horses. All the horses had been broke to harness and were beginning race training; each was considered fit to train by their trainers.

Drs. Anne Kallerud, Cathrine Fjordbakk, Eli Hendrickson, Emma Persson‐Sjodin, Marie Hammarberg,  Marie Rhodin and Elin Hernlund chose to study this group, which had an average age of 18 months, to reduce the chances of the presence of training-related injuries. All horses received a physical exam before the study; measurements were taken to see if any associations could be found with the uneven movement that could be detected.

Of the 103 horses, 77 were seen in-hand and on the track; 24 were assessed in-hand only and two were assessed only on the track. The scientists used thresholds established for other breeds to determine asymmetry. They determined that 94 of horses (93 percent) showed front and/or hind limb asymmetry in the in-hand reviews. In the track trials, 74 horses (94 percent) showed asymmetry. Though most of the asymmetry was mild, one in five horses switched the asymmetrical side for one or more parameters between in-hand and on-track trials.

The study team explored the prevalence of asymmetry, but not its underlying causes. It is unclear if the asymmetrical movement increases, decreases or stabilizes with age and training. They suggest that future studies look at the changes in asymmetry over time, and explore any associations between the asymmetrical movement and the development of clinical lameness.
