South Australia's Upper House will today be asked to set up an inquiry into the state's greyhound racing industry.

The proposed inquiry being moved by Greens MP Tammy Franks comes after the New South Wales Government announced a ban of the sport from July next year.

The NSW ban was proposed following revelations of live baiting and a report from a special commission of inquiry.

Mass graves containing racing greyhounds were also discovered.

Ms Franks said four other jurisdictions in Australia had already had similar inquiries.

"[The] top priority is what led the Baird [NSW] Government to ban this industry — that is the wastage rates," she said.

"How many healthy dogs are put down because they're too slow or not profitable? We need the truth and we need it now."

She said inquiry was needed because not enough was known about the industry in South Australia.

"We would have the greyhound racing industry in themselves and they can tell their side of the story," she said.

"And if they provide the figures in a transparent way then maybe they'll earn back the trust they seem to want."
