Punters will not be able to watch Victorian horse races on Sky Racing channels in their homes, pubs and clubs after a broadcast deal between wagering giant Tabcorp and the Victorian thoroughbred racing industry expired.

But the races can still be seen in the 92 Victorian TAB outlets.

Tabcorp says interim broadcasting arrangements expired at midnight on Monday, and a new broadcast deal with the Victorian thoroughbred industry has not been reached.

"As a result, while wagering on Victorian thoroughbred racing will continue to be available, it will not be supported by vision on (Tabcorp's) Sky Racing channels, outside of the 92 Victorian TAB agencies," Tabcorp said on Tuesday.

"Sky Racing is putting in place measures to minimise the impact on our customers."

Tabcorp has been in talks on new broadcasting arrangements for Victorian horse races since the beginning of the year.

Tabcorp submitted a formal offer to the Victorian thoroughbred racing industry on June 1, 2015.

The company said the package included significant monetary benefits, and the opportunity and flexibility to have up to 44 meetings each year broadcast on Channel Seven and other free-to-air television.

Tabcorp shares were two cents higher at $4.76 at 1056 AEST.
