About Us

Langdene Merino Stud, situated at Dunedoo in Central Western NSW, is owned and managed by Garry & Kel Cox.

The story on Langdene extends back to 1975, when the productive land of the historic Bocoble Merino Stud was resumed for the building of the Windamere Dam, near Mudgee.  This led to the dissolving of the Cox Brothers Partnership, of which Garry's father was a part.  The Bocoble Stud was retained by Garry’s Grandfather and Uncle at “Moolarben”, near Mudgee, and Garry’s family set about purchasing 1123 hectares at “Langdene” in Dunedoo.

In 1981, Langdene Merino Stud was established with the purchase of 800 Haddon Rig ewes, of which 200 of the top were selected for registration of the stud, and three stud rams.

In the late 1980's, genetic introductions came from East Roseville and Roseville Park studs, and later with an introduction from Nerstane.  In 2016 we registered a Poll Merino Stud with the transfer of horned stud ewes and the introduction of genetics from Willandra Poll and in recent years, Roseville Park Poll.

Infusing these bloodlines with the Langdene genetics has helped us to develop our own style of sheep for which we have become renowned.

In early 2018, Garry & Kel purchased the adjoining property, which increased the land holding to 2176 hectares, enabling us to us to increase our breeding flock.


Garry is the proud sixth generation Cox family Merino stud breeder, a fact not many family-owned studs can boast having six generations of successful Merino stud breeders!


“Langdene” & "Oakfield"

Our properties consists principally of red basalt soil, which is 95% arable.  We operate a three-year cropping rotation, and plant predominately to lucerne.  Our annual rainfall is 600mm.


Langdene Merino Stud features a base of 2000 stud ewes.  We undertake an annual AI Program of 1200 stud ewes and two comprehensive ET programs, each enabling us to utilise our top genetics. 


Our adult Merinos cut an average 7.9kg per year of 18.4 micron wool.


In varying climatic conditions throughout Australia, New Zealand, Argentina and Uruguay, many stud and commercial breeders have successfully introduced Langdene genetics, by either semen or rams to improve fleece weight, wool quality and, to increase body size and growth rates, whilst lowering or maintaining the micron in their flocks.


We are proud of what we produce and frequent fleece & ewe completions and sire evaluations with the confidence that our breeding principles result in high quality sheep and wool.
