The heat is expected to come off record-breaking British Breed ram sales such as those last year, when the new sale-season fires-up next month.
A few early White Suffolk sales on Eyre Peninsula have eased in average price, and sales in the prime lamb-producing heartland - the South East - are expected to drop from their $1000-plus average achieved in 2011.
But with new-season sucker lambs making about $100, there is still cause for optimism.
Landmark stud stock auctioneer Malcolm Scroop said demand should still be strong despite an easing in prices in the past 12 months.
"People would like to see the industry remain sky-high but it is not possible for it to be sustainable," he said.
"Lamb is still a very accepted product and the industry is still very sound, so we should continue to see buyers wanting to buy the best rams and paying for them."
Merino breeding-ewe numbers appeared to have reached critical lows and many producers had been intent this season on buying Merino rams to rebuild their self-replacing flocks.
"There might be some short-term pain for long-term gain," he said. By breeding up the Merino numbers down the track, these ewes will then be mated to British Breed rams."
He did not expect much change to buying preference in the terminal sire breeds, with White Suffolk and Poll Dorset breeds having a strong hold in the market.
"We are very lucky in South Australia to have such an extensive selection of rams of every breed with similar numbers to last year," he said.
"There is almost a stud and ram sale in every little area and we also have some of the biggest lamb processors in Australia in our State," he said.
Elders stud stock manager Tom Penna expected the top-end of the SE sales to be similar to last year but acknowledged it could be harder to shift numbers of British Breed rams in the northern areas of the State.
"In the SE it will be par for the course. We might see $100 come off the averages from last year so instead of $1000 they may average $900."
Specialist lamb producers with Merino-Border Leicester or composite ewes would stick with their programs but if crossbred lamb prices did not hold up, those running Merinos and Dohnes could turn to a wool focus.
"Producers realise that it (the lamb market) could not continue at the levels they were but it would not want to slip from where it is now otherwise they will be looking at other alternatives," he said.
He anticipated that across the State there would be a 10 per cent to 15pc oversupply of terminal rams.
The most sought-after rams would be those with a balance of good estimated breeding values with high growth and muscle and positive fat.
