WHILE maintaining a thriving sheep mob throughout drought-like conditions has been challenging for mixed farmer Tom Weckert, he says his Prime SAMM-cross ewes have performed above expectations.

Tom was attracted to the breed more than 13 years ago when he was looking to graze a "hardier sheep" at Orroroo.

Previously, the Weckert family had run Merino ewes across their Brinkworth and Orroroo properties.

"We wanted to breed a meatier sheep but with quality wool too," Tom said. "We aim to produce a true dual-purpose mob."

Tom farms with his parents Andrew and Patsy and his wife Abbe at Orroroo and Brinkworth. After experiencing continued dry seasons, he has destocked from 1700 head of sheep to less than 800.

About 400 SAMM-Merino ewes, down from 1100, are run on 2900 hectares at Orroroo and 400 Merino ewes - previously 600 - are run at Brinkworth.

"Throughout summer we destocked quite heavily," Tom said.

He said although the breed's hardiness meant it was suited for Orroroo's marginal country, sheep would have struggled to retain condition this season on such "bare paddocks.

"SAMM ewes are able to hold their condition but we still had to change the breeding base pretty dramatically because of a lack of feed," he said.

Tom also praised SAMM ewes' good mothering abilities and quality milk production.

"I can drive around the paddock and they are very protective of lambs," he said.

"Ewes have a solid structure too and are quite tall when compared with other breeds."

SAMM-Merino ewes are joined to Sunnybrae-blood SAMM rams to produce a prime lamb while Merino ewes are joined to SAMM rams to self-replace the flock at Orroroo.

Tom said he was interested in the breed's ability to transfer its maternal characteristics into a quality lamb and also maintain high fertility.

"We have joined SAMM ewe lambs at 10 months old for about 10 years and we had 70 per cent to 96pc joining percentages," he said.

"The main ewe mob reached 133pc for our best joining percentage but across an eight-year period we have averaged 112pc.

"Last year we only had 100 millimetres of rain for the growing season and we still had a joining percentage of 104pc."

SAMM-Merino ewes are joined in January and lamb in June/July to ensure there is a quality feed supply for lambs, while Merino ewes are joined in November for an April lambing.

June/July-drop lambs are weaned at 12 to 15 weeks and then put on legume stubble throughout summer but last year, for the first time in about five years, lambs were fed pellets in a feedlot.

"It was worthwhile because of the high prices for lamb," Tom said.

Lambs are feedlotted for four to six weeks and sold on-hook at about eight to nine months old, with lambs sold in March making $223.

Lambs reached 25 kilograms to 28kg dressedweight and Tom said lambs measured up to 47pc for carcase yield.

"A Merino lamb might be 42pc for carcase yield so the SAMM breed has helped to increase that. Even if lambs were just in the paddock it would still be about 45pc," he said.

Tom said the SAMM breed's plainer body also allowed him to stop mulesing lambs.

"We stopped mulesing wether lambs 10 years ago and ewe lambs about two years ago - that was also a large part of why we chose the breed," he said.

Tom said wool played a pivotal role in sire selection.

"When we select rams we always focus on wool figures - the breed already has quality carcase traits so we focus on selecting for wool in rams to make sure its quality remains high," he said.

The average fleece weight for SAMM ewes is about 5kg to 6kg and last year, the 21-micron wool from lambs made 1400 cents a kilogram.

"The ultimate aim is to produce more wool and lambs out of less ewes - the breed can help us do that," Tom said.
