Lines Gum Hill Poll Merinos - Continual Improvement Through Innovation - est. 1885

Continual improvement through innovation

Gum Hill Poll Merino Stud is the core focus of a mixed farming enterprise run by the Lines Family in the Mid North of South Australia. The district is characterized by a 425mm average winter dominant rainfall pattern, with the growing season typically from May to October. The business comprises 3400ha and involves the Poll Merino Stud, a commercial sheep flock, a cereal cropping program and some hay production. Gum Hill runs three core properties in the Mid North where the Stud Ewes, and all young sale rams are run.

At Keith, in SA’s South-East, properties are run by Haydn and Poppy Lines and family which provides an opportunity to test genetics in a different climatic zone, with higher rainfall and sandy soils putting pressure on different traits. A portion of the Stud flock is based in the South-East, and ram lambs are bred and sent to Gum Hill after weaning to be measured, tested and prepared for the sale team.

Find rams graded for YOUR budget

We offer individual breeding advice and ram selections tailored to the client needs, taking into account their production systems, environments and breeding goals.

Photos from Gum Hill Poll Merino Stud's post The McLellan family of Rand, NSW, have been travelling to South Australia for decades to purchase good doing easy care robust Poll Merino Rams. 26 years ago they came up the driveway at Gum Hill and have travelled 1000’s of km’s over the years to get rams ever since. An association now spanning across a few generations, it’s always a pleasure to work together 🤝
It was great to call in on Lee and Amanda, check out what they are doing, and how the season is progressing! We are so grateful for the opportunity to display some of their ewe Hoggets in our tent at the Henty field days. Feedback was really good about having some local Gum Hill bloodline sheep on display 25 Likes

This week 850 DNA samples have been collected on our 2026 drop Ram lambs in the Mid North and South East, these Genomic tests are the first step in forming a picture of each individual lambs combination of traits, pedigree, poll/horn status and birth and rear type.
Alongside this genotype a wide variety of profit- driving traits will be objectively measured and scored between now and next May whilst the rams are run under mob pressure and commercial conditions
📸 Have a peak through these photos, some of these young boys could be the next Gum Hill Sires, flock improvers for clients across Aus or complete duds! Time will tell

It was great to get some feedback on our rams bred out of our Gum Hill Southern Index Flock which we’ve been working on the last few years, particularly about the wool quality, carcass shape and functionality of these rams for farming systems in the south- east/ Western Vic.
Some awesome groups of rams heading out the gate with the physical attributes people are after and also genetically lifting the standard across multiple money making traits, combining physical functional traits (feet, wools, bodies/frames, point cover) with genetic improvement for growth, fleece value, carcass, fertility and easy care attributes ✅
Ram team averages up on last years ram teams and last year better than the year previously, continual improvement’s the name of the game!

Photos from Gum Hill Poll Merino Stud's post NEXT YEAR’S LAMBS TODAY🧬📊
Marked the progeny from our Ewe Lamb joining last week, an incredible year to have our first go at it with the ewes well grown out and holding their body condition really well. These ewes are April/ May drop 2025 and lambed in June/ July 2026. Lambs are looking fresh, crazy to think from a genetics perspective we usually wouldn’t see these lambs existing for another 12months.
From a practical management perspective great to utilise some lease land and take advantage of a good start by increasing stocking rates, and getting a few hundred more lambs for some extra cash flow 💰all without the bio security risk or cash required to buy in ewes
Our RESULTS
Foetus survival from Scanning to Marking 72%
Marking Rate 89% from an initial conception of 56% in lamb overall.
Will be interesting to see how these ewes bounce back and join up at our more conventional hogget age alongside their sisters who scanned dry, and follow them through for next years lambing.
A few ram lambs kept here too so exciting to see how they shape up alongside our main drop💥
Lots to learn and we’re by no means experts just sharing how it went and looking forward to watching it play out, thanks again for all those that have shown interest in this part of our sheep program 🤝 47 Likes

A lot of rain on them since last shorn in September 2025, and plently of green grass this year and they’re really bouncing along.
Solid frames , big bulky white fleeces, good doing ability all with solid feet and structure on a plain body
Well performing sires include; 237061 (son of stud superstar GH 215722) , 222593, and discovered 224304 (100% strike rate!) with 26 daughters through the race and no Hoggets graded culls or bound for the commercial flock, top end across the board visually and extensive measurements- what we aim for! 3 Comments 48 Likes

On board for our South East On- Property display tomorrow we have a pen of purpose bred Non- Mulesed rams. We begun breeding some Non-Mulesed Rams a couple of years ago to cater for clients seeking that direction with their breeding and wool accreditations. We are passionate about getting the non- mulesed traits right ( low wrinkle, dag etc) but also keeping a robust, good doing, hardy animal that cuts a bit of wool as well. Our Customized ‘Gum Hill Plus’ Index seeks to rank and represent the type of sheep that will breed these traits best. These sale rams are some of the results from this specialised mating program and will be at Keith tomorrow on display for those interested
