Kurra-Wirra Livestock Genetics

Kurra-Wirra Merino

Kurra-Wirra Merinos are bred with one aim: rams that perform in a commercial operation. Everything we do is measured — that's where "Measured to Perform" comes from. Our stud runs alongside a 30,000-head commercial flock, so every ram we sell is backed by genetics proven under the same conditions our clients farm in.

Non-Mulesed Commitment

​We breed rams that let commercial producers run non-mulesed flocks. It's been part of the program for years — selecting plain-bodied, low-wrinkle sheep that don't need mulesing, without giving up wool cut or quality.

Repro/Maternal Focus

Reproduction and maternal ability drive our program. Running at high stocking rates (17.8 DSE/ha), we collect accurate reproductive data, Maternal Behaviour Scores and birth weights across the flock. That data puts Kurra-Wirra among the leading Merino studs in Australia for reproductive traits.

Gold Standard Data Quality

We've used ASBVs since 2014 and genomics since 2015, with more than 3,500 animals genotyped and all stud animals now being genotyped. Our data quality is rated gold standard. More data means fewer guesses — selection decisions here are made on numbers, not looks.

Early Maturity Advantage

Early maturity is a genuine edge. Each year we join 100–150 eight-month-old ram lambs into the commercial ram team, and only a handful of elite rams are kept for stud use — the rest go to clients. When we joined the entire drop of stud ewe lambs at eight months, 60% scanned in lamb carrying 144% foetuses. You only get that result by breeding for it.
