The racing industry was rocked on Thursday night when ABC's 7.30 program uncovered an investigation into the treatment of racehorses.

The report uncovered alleged acts of animal cruelty on a mass scale, with allegations that hundreds of Australian racehorses were being sent to slaughterhouses.

Racing officials have been quick to condemn the alleged actions of a Queensland abattoir, where footage showed the shocking mistreatment of horses.

Among those to stand up and support the thoroughbred industry on Friday was Riverina Equestrian Association life member Elaine Furze, who oversaw the Wagga Horse Trials last weekend.

Furze revealed about 50 to 60 of the 160 entries at last weekend's trials were ex-racehorses. The trials also award an annual trophy to the best performed 'Off The Track Thoroughbred'.

"It just shows that thoroughbreds do have another life," Furze said.

"People need to know that they don't all end up there (at an abattoir).

"At least 50 of our entries were off the track thoroughbreds. Australian thoroughbreds are ridden all around the world.

"A lot of pacers and trotters actually make very good dressage horses while horses off the track are good for eventing."

Wagga trainer Scott Spackman can remember just about every horse he has trained and where the horse has ended up at.

He, like most trainers, takes great pride in finding a home for his thoroughbreds once their career at the track has finished.

Only recently, he and owner Noel Penfold sponsored Rocketcod to undertake a new career showjumping with Jim Scobie at Gundagai.

Rocketcod only had the one start for Spackman and Penfold, running last at Gundagai. The pair ensured it found a new home and the thoroughbred has now made it to the final of Jumpoff, a showjumping competition designed specifically for ex-racehorses.

"We gave him to Jim Scobie for the idea to try him as a jumper and the rest is history. What he's done is pretty impressive actually," Spackman said.

"I nearly know where all of mine are. Alert Rein is with Jim. Black Fusion and Missy Moo Cow are sitting in Harden with a young lady named Courtney. Louise Evans has a couple of mine. Marpenny was sent to a trainer in Nyngan to race her. He loves her to death. Tyson's Tiger is out at the uni, where he's got a home for life.

"We find homes for them. We care for them too. People think it's just a money-making scheme. Most of the horses sleep better than we do."

Racing NSW chief executive Peter V'Landys unequivocally condemned the alleged abhorrent actions of the Queensland abattoir.

"The vision was sickening, and horrendous and Racing NSW calls upon the Queensland Government and its Department of Primary Industries to take the strongest possible action against the alleged perpetrators of such cruelty," V'Landys said.

"Such conduct and any mistreatment of horses is not tolerated in the NSW Thoroughbred Racing Industry."

V'Landys also pointed out that Racing NSW is the only state in Australia that has a rule of racing that prohibits horses from being sent to a knackery or abattoir if they have been predominantly domiciled in the NSW Thoroughbred Racing Industry.

He pointed out further, in NSW it is illegal for an abattoir to process a horse for human consumption, unlike other states.
