MERINO lambs on the Lanz family's New England property "Yarramundi", Deepwater, have only been drenched once since birth, where normally they would have had three to four by now.
The new Barber's pole worm vaccine, Barbervax, was used and the wool producers are happy with the results.
Brian and Jen Lanz and son Nic run both sheep and cattle on 1750 hectares over three properties of blue granite and basalt undulating country running back to hills.
It's mostly native wallaby and red grass pasture, which is aerial sown with fescues and phalaris and fertilised.
In winter, they sow ryegrass and turnips over 50ha, plus similar areas to cocksfoot, sub and white covers and prairie grass.
The family runs 2000 ewes, some of which are joined to Border Leicesters, 1600 grown wethers and 1200 lambs.
"Barber's pole is our single biggest challenge and we have resistance to a lot of drenches," Brian Lanz said.
"The first vaccination was given at lamb marking the first week of November, the second three weeks later and third three weeks after that and then two more six weeks apart.
"Costs were on par with our normal program but we expect longer-term savings and will definitely be using it again next season.
"It's a terrific breakthrough for our industry."
