The animal welfare charity group on Saturday announced that it would receive $400,000 for its inspectorate services from July 1, down from a $600,000 allocation in the 2013-14 financial year.

The organisation posted a plea on Facebook, urging its supporters to contact Primary Industries Minister Jeremy Rockliff with feedback about the proposal.

At the time of writing the post had received 334 ``likes'' on the social media host and 32 ``shares'' from its pool of 26,775 followers.

Mr Rockliff said the organisation received heightened funding in recent years due to struggles with its governance and operations.

``My department is negotiating a new, three-year service agreement with the RSPCA,'' Mr Rockliff said. ``The government has had a service agreement with the society to provide an inspectorate service for many years and will continue to do so into the next financial year.''

RSPCA Tasmania general manager Peter West said he recognised past turmoil within the group, but said it still required the funds to maintain a bottom line of services.

``There was an independent report conducted by a public accounts committee which found that the government needed to work with the RSPCA to fund it better,'' Mr West said.

``All we're saying is that we want to have a fair-dinkum conversation about it - they said `this is what you have, how are you going to spend it'?''

He said the allocation meant the RSPCA would have to cut back its inspectorate's intensive farming services, handing the responsibility to the Primary Industries, Parks, Water and Environment Department.
