3-D Printer Makes Equine Neck Replica To Train Veterinarians

Similar to doctors in human medicine, veterinarians spend hundreds of hours honing their skills in laboratories before they begin practicing in the field. Learning how to administer joint injections is no different. The equine neck has a complex set of muscles and vertebra, but a new 3-D printer is making it easier for vets to learn how to precisely place ultrasound-guided injections.

Veterinary students typically learn how to do this procedure on equine cadavers, which have a limited shelf life and also have a delay in getting injection results to learn what may have been done incorrectly. To see if 3-D models might be a useful teaching tool, Dr. Alex zur Linden, radiologist and Ontario Veterinary College researcher, joined Dr. John Phillips, an engineer and director of 3D printing in the University of Guelph's Digital Haptic Lab.

Watch a video on how the 3-D models are created below.

Once a CT scan of an equine neck is complete, computer software will highlight the part or parts of the scan that will be printed. The printing takes between three and six hours. The team tested 13 different materials and printers to determine which one best simulated real bone using ultrasound; six of the materials worked for simulating bones or joints.

The model vertebrae were then embedded in ballistics gel that simulated the soft tissue around the bones. The models give vet students the ability to practice procedures with instant feedback; they're also efficient and reusable. Once the lab is complete, the model can be melted down and used again.

The research team is hopeful that the models will become a resource for the scientific community and spur the creation of other3-D models for horses and other animals.

Art Collector Jockey Hernandez Helping Put Spotlight On Second Stride Aftercare Program

Three-year-olds are horse racing's glamour division, and taking center stage on Sunday's 10-race program at Ellis Park in Henderson, Ky., is the $200,000 Runhappy Ellis Park Derby and its leading Kentucky Derby contender Art Collector.

But during that 1 1/8-mile race, Art Collector jockey Brian Hernandez Jr. will be bringing attention to horses far from the limelight: retired racehorses and industry efforts toward rehoming them after they're through at the track. In that regard, Hernandez will be wearing the name Second Stride on his white riding pants in the Ellis Park Derby, the first and pending another pandemic the only Kentucky Derby qualifying race ever to be held at the western Kentucky track.

Trainer Tommy Drury, who is 3 for 3 since receiving Art Collector early this year from owner Bruce Lunsford, is on the advisory board for Second Stride, the accredited thoroughbred rescue and aftercare facility in Prospect and Pleasureville outside of Louisville. Drury, Lunsford and Hernandez hope to gain recognition for Second Stride and the concerted effort by horse racing to find safe homes for its retirees, including retraining many for second careers.

For every Art Collector, there are thousands of horses who don't have a future breeding career. Founded by horsewoman Kim Smith, Second Stride is among 160 facilities across North America accredited by the Thoroughbred Aftercare Alliance to offer adoption, rehab and equine-assisted programs as well has sanctuary. There are nine TAA accredited programs in Kentucky, all but Second Stride located close to Lexington. Indiana is home to one accredited organization, Friends of Ferdinand in Indianapolis.

“It's such a good program and a much-needed program,” Drury said. “As trainer, we'd be lost without Second Stride. They find these horses good homes. Kim and her staff do such a great job. This is just kind of saying thanks for everything they've done for us.”

Staff by volunteers, Second Stride provides professional rehabilitation, retraining and placement of retired thoroughbred racehorses, adopting out an average of 100 horses a year, including 83 the first seven months of 2020. The program specializes in giving retired thoroughbreds the training they need to succeed in a second and sometimes third profession, such as with horses no longer being bred. The organization is one of the few aftercare facilities that will take male horses that haven't been gelded.

“We transition them to whatever each individual horse wants to do,” said Smith while watching Art Collector train earlier in the week at the Skylight training center in Oldham County. “As Tommy tries to get into their brain when they're here, we try to get into their brain and figure out what their next mission is going to be. We've placed horses in everything from polo, jumping, dressage to family horses. It's amazing to find out what these horses can do, the thoroughbred, and how versatile they are. Barrel horses, we've had some police work — especially a mounted unit that likes the big black horses.”

To have Hernandez displaying Second Stride on his leg, Smith said, “For us, it's just humbling that they would consider us. It's mind-blowing the national coverage just to get aftercare out there, and all the horsemen are doing for the horses. Thoroughbred Aftercare Alliance has been life-changing for our program and for the horses, with the sponsorship we get and also the mentoring and the education they provide our program in how to exceed. To have these hometown heroes being at Ellis is just going to be amazing. Tommy helped us set the foundation of the program and Brian Hernandez and his family come to our events and support us. So it's awesome. We're just proud of Tommy and Brian and the horse. It's super exciting.”

TAA Spotlight: From Foaling Barn To Second Career, Wiley Has Been There For OTTB All Hundreds

On Feb. 24, 2013, Heather Wiley helped deliver the last foal born at Dare to Dream Farm that year. The foal was a son of Silver Tree out of the With Approval mare Wings of Approval.

Wiley kept tabs on the horse, now named All Hundreds, as he ran in the claiming ranks at Gulfstream Park and Gulfstream Park West throughout his 3- and 4-year-old seasons. Throughout 2018 and into 2019, he moved between Tampa Bay Downs and South Florida. And on May 4, 2019, he was claimed out of a Tampa Bay race and relocated to Camarero Race Track in Puerto Rico, making his next start a month later. Wiley continued to watch from afar as he ran regularly in claiming races at Camarero.

Through a mutual friend, Caribbean Thoroughbred Aftercare's Kelley Stobie was introduced to Wiley and knew she was trying her best to keep tabs on his whereabouts. When All Hundreds was retired in March of 2020, Stobie let Wiley know she had the grey gelding at her TAA-accredited organization, and arrangements were made for him to begin his quarantine and travel back to Wiley on the mainland. The gelding finished his career with a 7-7-7 record from 42 starts and $93,400 in earnings.

Now, Wiley and All Hundreds are happily reunited as they begin the next chapter in their lives, which will be filled with many trail rides.

“He is doing wonderful,” she said. “A real sweetheart as always.”

Study Provides Information On Fate Of Australian Racehorses

Scientists at the University of Melbourne created a study to determine why some Australian Thoroughbreds did not enter race training. Drs. Meredith Flash, Adelene Wong, Mark Stevenson and James Gilkerson examined the records of Thoroughbreds born in 2014 to determine how many horses had not entered race training by the end of their 4-year-old season (August of 2018).

They discovered that 13,677 Thoroughbreds were born in 2014. Of those, 66 percent started training and 51 percent had raced before the beginning of their 4-year-old season in Australia. The scientists chose a geographically diverse sample of 4,124 horses to use as part of a study. Of those, 1,275 horses had not entered race training.

Breeders of the 1,275 horses that had not entered race training were sent an online survey, then received a follow-up call to discover what happened to the horses. Fifty percent of the breeders responded. The researchers discovered that each horse fell into one of four categories:

Alive and active within the Thoroughbred racing industry
Alive and active outside of the Thoroughbred racing industry
Exported
Deceased

The scientists discovered that 154 horses were actively training or racing and 84 horses had been sold at a public or private sale. Many breeders indicated that they were not sure what happened to the horse once it sold. Only one horse was reported as exported.

There were 83 horses reported as retired or rehomed, with 61 percent of these never having any official training. Illness or injury and then poor performance were cited as the main reasons for retirement.

The reports discovered that 239 horses had died, with just over half dying in the first year of their lives of reported congenital malformation. In total, 73 percent of the horses that died passed before they turned 2 years old; these horses were not eligible to start in a race when they died.

Twenty horses had owners that were still intending to race them; the fate of the final 35 horses was unknown, meaning the owners stated they could not remember, did not know or did not choose a response.

The scientists extrapolated the results and concluded that most Thoroughbred deaths in the 2014 foal crop were related to non-training illnesses or injuries. They suggest that research into farm design and infrastructure might provide information to lower the fatality risk to horses. They also note that while official race records indicate the number of horses that start, data underestimates the percentage of foals that enter training.
