A report from the inquiry, tabled in state parliament on June 20, has made 14 findings and 18 recommendations.
Chief among them were for the Victorian Government to impose mandatory closed-circuit television in all processing and farming facilities, a ban on sow stalls and farrowing crates and phasing out the use of side-loader carbon dioxide stunning systems.
Under Australian law, pigs must be stunned before their death in a bid to ensure they do not feel pain. The only legal forms of stunning are by carbon dioxide exposure or by knocking them out with an electrical current to their head.
Other recommendations include working to find an alternative to the use of blunt force trauma as a suitable method of piglet euthanasia, support for farmers to transition to outdoor group housing and consideration to establish an independent office of animal protection.
Inquiry chair and Animal Justice Party MP Georgie Purcell said the codes of practice, regulations and legislation surrounding the Victorian industry are complex, with many different farms subject to different levels and standards of care.
"A clear theme throughout the inquiry process was concern surrounding self-regulation," she wrote in the report.
"Despite the pork industry acknowledging pig cruelty and committing to a voluntary phase-out of sow stalls by 2017, there are still farms that have not complied.
"Without oversight, consumers are misled into purchasing products they might falsely believe is sow-stall free."
Sow stalls are designed to protect pregnant pigs from being injured in fights with other pigs by confining them alone in a tight space in which they cannot turn around.
A minority report from Liberal and Nationals inquiry members dubbed the inquiry's findings and recommendations "ideologically motivated".
They accused Ms Purcell of using emotive language in a deliberate attempt to discredit what they described as a highly regulated industry known for its "excellent compliance".
Opposition agriculture spokeswoman Emma Kealy said it was concerning Labor members of the upper house committee voted in favour of the "extreme restrictions".
"Labor had the numbers, they had the opportunity to stop this nonsense, instead they sat silent," she said.
"This report should send a shiver down the spine of not only pork producers, but all agricultural producers in Victoria."
