THE RSPCA will vigorously enforce new animal welfare laws at Tasmanian rodeos this season.

The society's chief executive Greg Tredinnick said legislative changes had outlawed the riding of sheep, goats and calves and also made attendance by a veterinary surgeon compulsory at every event, the Hobart Mercury reports. 

"In previous years, there have been absolutely no enforceable specific requirements for these types of events, apart from voluntary guidelines, and those sections of the Act relating to animal cruelty," Mr Tredinnick said.

"This year however, there have been significant changes in legislation which clearly spell out who is responsible and what their responsibilities are."

Mr Tredinnick said requiring onsite veterinary care was a big step forward.

"In addition to treating or euthanasing sick or injured animals, the vet can also prevent an animal from taking part and is authorised to act in the best interests of the animal to ensure its welfare," he said.

"To make sure these new laws are being observed, the RSPCA will be undertaking a series of random inspections across the season and anyone found in breach of the amendments could be charged.''

The penalties for breaches of the Act include fines of up to $6000 and up to 12 months in jail, and $24,000 fines for organisations.

He said the organisation would prefer a ban on rodeos. 

"The RSPCA will continue to advocate a ban on rodeos while animals are still at risk of injury and exploitation," he said.

The RSPCA is developing a code of practice for rodeo operators.
