The owners of a family-friendly farm cafe forced to close on Sunday say they have been personally threatened in a campaign of harassment by animal activists against their business.

John and Penny Gommans, both 61 announced via Facebook on Sunday they were closing their Gippy Goat Cafe in the small Victorian town of Yarragon, about 110km south-east of Melbourne.

Besides operating as a full cafe, the venue manufactures a range of goats milk products and families are free to feed the on-site goats and watch them being milked.

But Sunday is set to be the eatery's last day of operation.

John Gommans said it followed a sustained campaign of threats and harassment by activists - including the theft of three goats and lamb last December.

And last month one of the activists responsible for that incident was fined just $1 for each of the thefts and $250 in compensation.

But Gommans said activists had also threatened the couple personally.

"They've threatened to come and do us harm," he told 7NEWS.com.au

"We have had some threatening phone calls to our personal phone numbers and we then provided those phone numbers to police, but the phone numbers were all under fictitious names.

He said while police had been supportive, other authorities were not taking the issue seriously and the couple felt let down.

"Incredibly let down, a lot of people have put their heart and soul into The Gippy Goat," he said.

"But every second phone call has been telling the staff how bad they are and what a terrible industry we are working in, and that’s not to mention the threats."

He said other farms in the area had also been targeted.

"It is very widespread I was amazed how many farmers rang me to say they had been invaded, chicken, rabbit, pig and dairy farmers, it's widespread," he said.

On Sunday morning the Gommans posted their sad news on the cafe's Facebook page, revealing they were closing the cafe.

"For the sake of our health and safety and that of our families and staff we feel that it is regrettably the best option," they wrote.

"Our staff and customers have been subjected to nearly 4 months of constant harassment, vile statements and threats from the abusive vegan activists.

"We have personally been subjected to an appalling stream of threats of extreme violence against ourselves, our family, our staff and even their families.

"Our staff have been subjected to daily threats and harassment by phone, and we cannot in good conscience ask them to continue working under such a condition," they said.

"Eight good people are now without a job, families no longer can enjoy the good food and open space, and children can no longer interact with our animals."

State Nationals MP Melissa Bath expressed her disgust.

"Im bitterly disappointed to see that their fabulous business and staff have been so shockingly harassed by activists. I will fight in parliament to stop this atrocious behaviour," she said.

"Good people, innocent people being targeted in this way is totally unacceptable and unAustralian."
