The Tasmanian Livestock Exchange at Powranna held its first sale under the new brand on Tuesday and introduced its new system.

TLX assistant Mady Muirhead said the system was an end-to-end sale softwater called AgriNous, which provides live sale information for buyers, sellers and agents. AgriNous helps to collect data on livestock sales, such as vendor and buyer information, as well as breed and price information.

"It's used a lot on the mainland, but it's the first time we've used it in Tasmania. It's entirely online, and it hopes to replace the paper trail." Miss Muirhead said the system allowed TLX to give live and up-to-date information as the sale unfolds.

Manager Andrew Palmer said it was the first time pigs were brought for sale alongside sheep and cattle.

The Tasmanian Livestock Exchange is part of Nutrien Ag Solutions' rebrand of the livestock sales industry in Tasmania.

It follows the closure of saleyards at Killafaddy and Quoiba to the centralised site at Powranna. Sales are weekly on Tuesdays.

Mr Palmer said the first sale was successful and well attended by Tasmanian farmers and buyers.

He said despite COVID travel restrictions, interstate buyers were still able to be part of the sale, thanks to their local connections.

"Interstate buyers often use their local Tasmanian reps, who will attend on their behalf, it's a longstanding arrangement that happened even before COVID," he said.

"But before COVID, we would expect some buyers to come from Melbourne, which we hope will happen again [when restrictions lift]."

Numbers of livestock at the sale remained on par, and Miss Muirhead said things hadn't changed much compared to previous years.

Cattle prices for yearlings, feeder steers and feeder heifers were generous. Pork remains steady.

However, lamb prices have become weaker due to the closure of abattoirs in Victoria due to COVID.
