Research by Massey University scientists shows that a change to self-shedding sheep will be profitable in the long-term.
Aside from shearing, the costs of crutching, dagging and flystrike are all eliminated with these shedding sheep. Meanwhile, Wiltshires are said to be more resistant and resilient to internal parasites than their wooly counterparts.
Will Pears, stud manager at North Canterbury's Mt Cass Wiltshire stud, says last year's inaugural sale exceeded all expectations in terms of price and interest. He is expecting the same at this year's sale on January 19.
Pears says last year more than 100 buyers from around the country competed strongly for both rams and ewes and feedback from purchasers has been overwhelmingly positive.
One of those buyers was Waimate farmer Tim Mehrtens. He admits it took a leap of faith in buying Wiltshire ewe lambs and rams at the Mt Cass's sale but was rewarded with a good lambing percentage and very good pre-weaning growth rates.
Mehrtens, who farms 215ha of rolling hill country, says the shift to Wiltshire genetics was driven by frustration with poor returns for wool. While he has been buying very good composite ewe lambs, in 2020 the difference between shearing costs and the wool cheque left him $3,500 out of pocket.
The first crop of pure Wiltshire and Wiltshire cross lambs, born last spring, exceeded expectations. Mehrtens says he was pleasantly surprised at the pre-weaning growth rates and their mothering ability.
Forced to wean early due to limited processing space, he says 220 twin male lambs killed out at 17.5 kgCW and a line of Wiltshire cross lambs averaged 17.7 kgCW.
Mehrtens has also noticed that a lot of the first cross lambs have started to shed.
"I'm stoked with the results," he says.
