One of the most influential sires currently in the industry, Lachlan 220118 stood out early as a ram lamb, and selected for both Artifical Insemination (AI) and Embryo Transfer (ET) use.
From the outset, he has displayed exceptional correctness, balance and presence.
He stands square and correct on all four feet, with outstanding structural integrity and symmetry.
His hindquarters are well shaped, and his overall body stucture is strong, balanced and correct.
Width and capacity flow smoothly from front to back, complemented by a refined, pure, soft muzzle.
He carries a long, soft, free-growing fleece on a loose, uncomplicated skin, with exceptional whiteness carried through to the belly. A highly versatile sire, he suits joining across a wide range of ewe types without compromise.
Lachlan 220118 is the best ram we have ever bred, and his progeny performance continues to reinforce that belief. His offspring are consistently well balanced, displaying outstanding length, depth, and hindquarters, while carrying thick, waxy, white wool with excellent staple length and lock definition on uncomplicated skins.

One of the most influential sires in the Merino industry today.
Originally destined to be retained as a stud sire at Wiringa Park, WA, we were fortunate to secure him privately for $70,000, along with a 50% semen share, following the 2023 Australian Sheep and Wool Show in Bendigo.
"This young ram stood out at weaning and has continued to develop into a tremendously well-balanced sire. He was used at Wiringa Park as a ram lamb, both through AI and natural joining, such was the confidence we had in him. He possesses all the attributes of a true modern stud sire – structurally correct with short pasterns, exceptional squareness, and wool that displays outstanding nourishment, lustre, staple length and density." – Allan Hobley, Wiringa Park
His wool quality is a standout feature, particularly through the hips and behind the poll, where he displays exceptional density, nourishment and style that are difficult to find elsewhere.
With progeny now on the ground across NSW, VIC, SA, TAS, QLD and WA in 19 stud and commercial ram breeding flocks, WP 220450 is proving himself as a highly productive and adaptable sire. His offspring consistently exhibit excellent fleece weights, strong carcase traits and outstanding structural correctness.
A key strength of WP 220450 is his ability to produce a high percentage of elite progeny with a remarkably low cull rate. Across a range of environments, his sons and daughters continue to demonstrate an ideal balance of wool quality, fleece cut and carcass performance.
