The markets were suspended at the outbreak of foot-and-mouth and since then the price of animals slaughtered at abattoirs has been negotiated by the multi-nationals.
But hard-hit farmers have complained that they are not getting a fair deal.
The news comes as the National Assembly confirmed Wales's 85th case of foot-and-mouth, at Sluice House Farm, Peterstone, Wentloog, near Newport.
The farm is contiguous to an earlier outbreak and an assembly spokeswoman said the cattle were in the process of being slaughtered when clinical signs of the disease were spotted.
A total of 90 cattle and 904 sheep on the farm were slaughtered on Saturday.
The auctions were first set up because farmers felt they were not getting the best prices for their animals. Foot-and-mouth forced them to close - some for good.
The Welsh farming unions and meat marketing board told the meeting the way forward was better branding and working with the supermarkets.
But many farmers have a deep distrust of the multi-nationals and leaders such as Brynle Williams warned there would be protests if prices slipped further.
Around 250 farmers attended Friday night's meeting, which resulted in a split, with the unions and marketing men on one side, who urged the farmers to work with the supermarkets and give them what they want.
Without export bans on livestock in place, farmers are relying on the home market.
Don Thomas, the director Welsh Lamb and Beef Promotions, said it was a "fact of life" that the supermarkets play a huge role.
On Friday, the future of the Bryncir animal market was discussed at a meeting in Garnbolbenmaen in Gwynedd.
The agriculture industry in north Wales was rocked last month when the Bob Parry company said they were closing their animal markets in Llanrwst, Talycafn and Bryncir.
Llanrwst market has since been saved and there are now hopes for the future of Bryncir market as well.
Now Farmers Mart - a farmer-based co-op - which holds markets in Corwen, Bala, Dolgellau, Machynlleth and Sarn is considering buying the Bryncir market, which is on sale for £250,000.
But as part of the plan, local farmers would have to buy £100,000 worth of shares.
'Chaos and confusion'
The farmers in the meeting unanimously supported the plan and £50,000 was promised in a matter of minutes.
The Farmers Mart board will decide on Monday night whether to go ahead and try to purchase Bryncir market.
Meanwhile, country landowners in Wales have described the government's own handling of the foot-and-mouth crisis as a "saga of chaos and confusion".
The Country Land and Business Association is calling for an independent public inquiry into what it calls " a catalogue of failures".
Campaigners from Powys and north Wales are expected to join in a lobby of parliament this Wednesday organised by the UK Rural Business Alliance.
The demonstrators will present Chancellor Gordon Brown with an invoice for £12.1bn - their estimate of the loss to the rural economy caused by the foot-and-mouth crisis.
Ian Mitchell, one of the organisers and chair of the Powys Rural Business campaign said "the full effect of the crisis has yet to be seen".
