A Tasmanian couple has been ordered to get rid of dozens of pigs living in their east coast home.

The home of miniature pig breeders Vicki and Morry Jackson has been taken over by more than 40 pigs.

Mrs Jackson has spent eight years developing new breeds of woolly pigs, which are unique because of their long hair.

For the past year, most of them have lived inside because of heavy rain, which has turned the Jacksons' backyard into a muddy mess.

Some are in pens that were once bedrooms and others roam free in the main living area, where the wooden floor is covered in pig feed and mud.

"We spend all day cleaning - we have to," Mrs Jackson said.

"The pigs themselves are clean though."

The distinctive animals all have names and are a novelty for visitors to the small north-east town of St Marys.

But neighbours have complained to the Break O'Day Council about their smell.

Mayor Sarah Schmerl says there are far too many pigs on the property.

"Council was made aware several months ago and our environmental health officer has been working with Mr and Mrs Jackson to try and reduce the number of pigs on the property," she said.

The couple has to get rid of all but 10 pigs by the end of this month or risk a $650 fine if a State Government order is issued.

Mrs Jackson says she has grown attached to the animals but accepts their living arrangements are untenable.

"I know we've got too many, but they're a tourist attraction," she said.

A farm sanctuary near Hobart has offered to take the pigs if other homes cannot be found.
