A Tasmanian abattoir has made animal welfare changes after an investigation by authorities.
The Department of Primary Industries (DPIPWE) conducted an investigation into the Cradoc Hill Abattoir after being sent video footage taken inside the facility in the Huon Valley.
The footage was filmed last year and sent to the department in August 2017.
A department spokeswoman said it found "insufficient evidence to proceed with further action".
"As such, DPIPWE found there were no violations of the Animal Welfare Act," she said.
The abattoir is the third in the state to be targeted by animal welfare activists who have managed to install hidden cameras.
Footage obtained from Tasmania Quality Meats and Gretna Quality Meats was also supplied to DPIPWE.
James Lord, the owner of Cradoc Hill Abattoir and Huon Valley Meat Co, said the department did make some recommendations for improvements.
"Some of which we had already implemented before the DPI [DPIPWE] spoke to us and the others we implemented straight away," he said.
Mr Lord, who bought the abattoir in 2011, refused to detail the recommended changes to the ABC.
"This can be a complicated environment sometimes, and I think it's best you talk to the DPI about the specifics of their investigation, I don't want to comment on their side of things," he said.
Mr Lord said animal welfare was "very important" to the company.
"It's first and foremost on our minds every single day, and we strive to have best practice in how we handle our animals," he said.
'This is supposed to be one of the better places'
Animal Liberation Tasmania held a candlelit vigil on Wednesday night outside Mr Lord's Hobart butcher shop, projecting footage from the Cradoc Hill Abattoir onto the building.
Campaign director Mehr Gupta alleged the footage showed improper stunning techniques and physical and verbal abuse of cows, sheep and pigs.
"What this footage displays, more than anything, is that animals want to live just as much as you or I or anyone else," she said.
"This place is supposed to be one of the better places.
"They label themselves as ethical and respectful of animals and yet we can see in the footage these animals are clearly terrified.
"What they're met with is just sheer disrespect and mocking."
The DPIPWE spokeswoman said anyone with information regarding animal welfare allegations should report them immediately by phoning the Animal Cruelty Hotline on 1300 139 947.
