We turned Merino lambs off at 7.5 months averaging 28kg cwt over the hook — weights we used to struggle to hit at 12 to 13 months.
We've been transitioning to Trigger Vale bloodlines for a few years, selecting rams on growth, muscle and fat. The result: wether lambs off at 7.5 months averaging 28kg CWT. The tops cut a $30 jacket of lamb's wool, then made upwards of $350 on the hook plus skin — around $390/hd gross. Turning off that early gives us real optionality: trading stock, running more ewes.
Early maturity flows through to fertility — 40% of weaned ewe lambs now conceive at 8 months, up from under 10% two years ago, and improving as the bloodlines compound. Low-wrinkle, bare-breech traits came as part of the package. We've ceased mulesing — and despite wet summers, no significant increase in dag or flystrike.
