What practical mental health support looks like in the shearing industry with Carol Mudford

4/12/2026
This week on the podcast, Mark chats with Carol Mudford to talk about her unconventional path into the shearing sheds and the work she is now doing to help improve mental health across the industry. Carol grew up around sheep but never planned to pick up a handpiece, starting her working life in nursing before COVID and family circumstances brought her back to the farm. When she was ready to return to nursing, Carol moved into mental health nursing within a rural suicide prevention programme, combining her experience from both the sheds and healthcare with the idea of forming a charity. After losing multiple people in the industry to suicide in a short period, her idea came to life much sooner than she expected. Now the founder of sHedway, Carol is working across Australia and New Zealand to improve awareness, reduce stigma, and give shearers practical tools to look after themselves and each other. Carol shares practical signs to look for when someone might be struggling, how to step in, and why being “helpfully nosy” can matter more than people think. This podcast episode discusses suicide. If you are struggling or know someone who may be struggling, support is available through local mental health and crisis services in your area.

Breeding seedstock for tough country at Hazeldean, with Bea Litchfield

4/5/2026
Bea Litchfield is Managing Director of Hazeldean, a sixth-generation family seedstock business running both Merino and Angus studs alongside commercial operations. Hazeldean is a large-scale seedstock business, and they produce around 600 Angus bulls and 400 Merino rams each year for clients across all kinds of environments. Their tough environment allows their stock to be put to the test and their rigorous focus on fertility, structure, temperament, growth and carcass has meant the Hazeldean name is well known around Australia. In this episode, Bea and Mark discuss their approach to breeding seedstock, which involves harsh winters and a LOT of data recording. The family has innovation in their blood at Hazeldean, so it's no surprise that Bea is excited about where emerging technology, including AI and on animal monitoring, may take farm businesses. She and Mark discuss this, amongst other things. - If you would like to help us reach our goal of raising $52,000 to fund vital cancer research, visit the link below: https://fundraise.curebraincancer.org.au/fundraisers/markferguson/twentysix2000 If you would like to join the Strava club, visit this link: https://www.strava.com/clubs/TwentySix2000?utm_campaign=club_share&utm_content=1858801&utm_medium=widget&utm_source=thehub.nextgenagri.com Head Shepherd is brought to you by neXtgen Agri International Limited.

Key tips to improving the reproductive performance of your beef herd with Dr Shane Thomson

3/29/2026
Join Mark and our guest this week, Dr Shane Thomson, to discuss some key points around reproductive performance in cattle. Shane is a veterinarian and partner at Holbrook Vet Centre in southern New South Wales, leading a team of 10 vets across a practice that's roughly 90% beef production. Cattle reproduction work is at the core of what Shane does daily, and in this episode, he and Mark cover pretty much everything. Including bull soundness, AI, embryo transfer, IVF, how to improve pregnancy rates in beef herds, what a pre-breeding bull soundness evaluation actually involves, how to prevent pestivirus and other reproductive diseases, when IVF makes more sense than conventional ET, and the role of sexed semen in beef operations. Shane and Mark wrap up their chat by discussing what he thinks are the biggest untapped opportunities in beef production. This episode is a goldmine for any beef producers wanting to understand their herd's reproductive performance. Head Shepherd is brought to you by neXtgen Agri International Limited.

Fat, fertility and the genetics of cow performance with Professor Wayne Pitchford

3/22/2026
This week on the podcast, Professor Wayne Pitchford joins Mark Ferguson to discuss all things cow condition. Wayne has spent more than three decades at the University of Adelaide working across animal breeding, genetics and livestock production, and is currently Director of the Davies Livestock Research Centre. Wayne and Mark discuss his recent research on the relationship between early body measures and adult traits like fertility and condition score, including why young animal data explains only a small part of cow performance. They also cover fat distribution across different depots and what that means for selecting more efficient and resilient cattle. Wayne and Ferg also talk through how you should interpret feed efficiency, carcass traits, muscularity and hip height to breed the right cow for your business.

Lifetime Ewe Management, leadership and the legacy that changed sheep farming, with Mark, Darren and Andrew [PODCASTHON]

3/15/2026
This week on the podcast, Mark (Ferg) catches up with Andrew Kennedy (Ox) and Darren Gordon (Cat) to reflect on their early years together as well as the career and influence of Dr Andrew “Tommo” Thompson. The episode is part of Podcasthon, supporting efforts to raise awareness for brain cancer research. Ferg, Cat and Ox reminisce about the early days of the Lifetime Ewe research project and the realities of running a large-scale sheep research under the legendary Andrew Thompson. This was before the use EID, which meant recording thousands of pasture measurements and condition scores by hand. That work, which began as a project focused on wool follicles, ultimately reshaped how the sheep industry thinks about nutrition, twin survival and ewe management. The research helped change the language we use around feed, energy, and condition score, and drove widespread adoption of better management strategies across Australia. Tune in to hear some great stories from the early days of these research trials with a few untold yarns about the situations these three managed to find themselves in. This is not one to miss!

Using Genomics to Improve Heifer Selection in Commercial Beef Herds

3/8/2026
Choosing replacement heifers shapes the productivity of a breeding herd for years to come. This week on the Head Shepherd podcast, James Starling joins Mark Ferguson to discuss the Meat and Livestock Australia Producer Demonstration Site focused on optimised heifer selection. Based on the Limestone Coast in South Australia, James runs a self-replacing Angus herd alongside a prime lamb enterprise. After two decades working in global financial markets, he returned to farming with a strong focus on data, value and decision making. In this conversation, James explains why identifying the right replacement heifers is one of the most important profit drivers in a breeding herd. The discussion covers how combining visual assessment with genomic tools can improve selection for first cycle conception, rebreeding performance, longevity and lifetime productivity. With TSU sampling and genotyping now underway across the project’s core herds, the goal is to generate practical data from commercial operations and test how well genomics can complement traditional drafting decisions. The episode also touches on market signals, cost of production, maternal versus terminal breeding strategies and why measuring performance is becoming essential for livestock businesses operating in high-cost production environments.

Understanding the wool industry pipeline with Shannon Donoghue

3/1/2026
This week on the podcast, Shannon Donoghue joins us to talk about telling the story of wool and why she's so passionate about it. Growing up on a sheep property in South Australia, Shannon started off in the industry through wool classing before stepping into her current role as an industry relations officer with AWI. Her work now involved helping producers better understand where levy investment goes and ensuring their feedback shapes research, development and marketing Alongside that, Shannon has built a significant following online, sharing drone footage and, more recently, "Weekly Wool Facts"- a series to get more people interested and extied about sheep and fibre production. Shannon also explains the shift in consumer attitudes post COVID and the move towards everyday wool in casual and athletic wear, rather than the standard woolen suit.

40 years of sheep selection lessons: worm resistance, longevity and performance with Allan Richardson

2/22/2026
How much do you hate daggy sheep? Well, what started as a frustration with daggy sheep ended up reshaping this week's guest’s entire farming system. This week, Allan Richardson explains how his determination to eliminate daggy sheep ultimately led to three decades of organic farming and the adoption of regenerative principles. He began by wanting to select for low dag score, but a local vet encouraged him to focus instead on worm resistance. Selecting for worm resistance made organic certification achievable. From there, Organic farming opened the door to regenerative principles focused on soil biology and long-term system health. Farming inland from Dunedin in a summer wet climate, Allan shares his wisdom from nearly 40 years of selection for worm resistance, resilience, short tails and longevity.

Ferg’s thoughts on the 25/26 ram sale season

2/15/2026
Tune in this week on the Head Shepherd podcast to hear Ferg discuss the 2025/2026 ram sale period across Australia and New Zealand. He explains his approach to selecting the right ram team and the decisions breeders have been facing when producing rams for sale in an increasingly data-driven market. Ferg discusses the breeding values gaining attention, as well as buyer behaviour when information is available AND when it is missing. He also explains the neXtPredict tool developed in partnership with Weatherbys and how it can support producers who want to better understand the genetic merit of their ram teams or wider flock if they have been purchasing rams without breeding values.

Breeding Romneys for the rain at Kaituna Ridges

1/25/2026
How do you breed sheep that thrive in wet coastal hill country without routine drenching? What traits actually matter when you're selecting for challenging conditions? This week on the podcast, Mark is chatting to Fred Gane, owner of Kaituna Ridges, an 800-hectare farm above Havelock and the Pelorus Sound in the South Island of New Zealand, alongside his wife Nikita. Fred runs a mixed grazing operation that includes over 5,000 Romney sheep and 200 head of cattle, as well as a Romney stud. Fred breeds dual-purpose romneys that thrive in their wet, coastal hill country conditions, which involves targeted parasite management rather than routine drenching of adult sheep, maintaining pressure on structural traits and selecting for animals that perform consistently in their challenging conditions. Fred also discusses diversification through the family farm’s multiple enterprises, including their wool brand, Kaituna Ridges, which adds value to the fibre they produce, alongside their tourism business that brings visitors onto the farm and showcases their operation. - For more information on our fundraising efforts for the "Cure Brain Cancer Foundation" visit this link: https://fundraise.curebraincancer.org.au/fundraisers/markferguson/twentysix2000 Head Shepherd is brought to you by neXtgen Agri International Limited.

Practical Breeding Strategies for Commercial Cattle Producers with Carel Teseling

1/4/2026
How can commercial producers use breeding values without recording full pedigrees? This week, Mark chats with Carel Teseling, Chief Operating Officer at Angus Australia, to find out. Carel's career has taken him from South Africa's regional performance recording programs to 14 years of developing genetic tools for Angus Australia, a decade leading Australian Wagyu Association's genetics, and now back to Angus again, giving him unique insight into what actually works for producers across different systems and breeds. Carel begins by sharing the story behind South Africa's groundbreaking work in livestock genetics during the 1990s, as well as his early days tackling genetic conditions in Angus, and his time at the Australian Wagyu Association. After 10 years at the Australian Wagyu Association, Carel returned to Angus Australia in 2025 as Chief Operating Officer, where he's overseeing the parallel running of the Trans-Tasman (TACE) analysis and Angus's new internal analysis. He explains how the internal system has been in development for almost five years, includes new traits like immune competence and body condition, and uses different methodological approaches such as avoiding pre-adjustments on carcass data. Angus Australia is letting breeders compare both systems to see how they re-rank animals. Carel explains that while there will be some re-ranking, both point in the same direction and will still guide breeders toward genetic improvement.

Ferg's thoughts on genetic gain

12/28/2025
Ferg shares his thoughts on genetic gain in the sheep and beef industries. He has often said that we should be seeking to achieve a minimum of 2% genetic gain, but the top operators we deal with here at neXtgen Agri are consistently achieving 3-4%. Ferg explains how they’ve achieved that with the use of selection accuracy and the compounding effect of disciplined breeding decisions over time. Ferg also talks about what that genetic gain actually means for each farm and what traits we should be looking at to optimise performance. Some traits benefit all farms, no matter the location (things like worms, dags and feet), and others that are more system-specific.

Selecting for Worm Resistance in Low-Challenge Systems with Swabtec

12/21/2025
What if measuring worm resistance didn't require high parasite burdens and ALSO delivered double the heritability of egg counts? Sarah Preston, Lecturer at Federation University and cofounder of Swabtec, explains the development of their saliva-based test designed to measure immune responses to gastrointestinal worms in sheep, allowing resistance to be assessed without relying on high worm egg counts. She and Mark discuss why egg counts often fail to reflect adult worm burden, particularly in mixed infections and with species that regulate egg production, and how this affects breeding and management decisions in well-managed, low challenge systems. They also discuss where they are with the development and validation of Swabtec. They are currently working to validate the test across breeds and environments and are planning to develop breeding values as the data builds. The test has been found to have a heritability of 0.4 compared to the WEC of 0.2 meaning flock improvements based on insights and data from Swabtec can occur twice as fast!

Individual ewe performance and the future of sheep productivity with Tara Dwyer

12/14/2025
What limits ewe productivity in current sheep systems? Our guest this week, Tara Dwyer is breeding manager at Headwaters Genetics and a farm manager within the Lone Star Farms group. Her work covers stud breeding, commercial supply chains, and large-scale sheep systems, and in amongst all of that, she found time to do a Kellogg report, "A New Fleece on Life: How the Sheep Farming Sector in Aotearoa Can Halt Terminal Decline to Secure a Sustainable and More Secure Future" Starting with her "day job", Tara and Mark discuss the value of genetics within a value chain, and how Headwaters is focusing on eating quality traits alongside maternal performance, resilience, and low-input efficiency. Tara explains how and why Headwaters selects for intramuscular fat and fatty acid profiles while still prioritising reproduction, lamb survival, and health traits. Mark and Tara then discuss her recent Kellogg report, which looks at why lambs weaned per ewe have barely shifted for decades, why carcass output improved while reproduction stalled, and why relying on ram breeders alone is not a reproductive strategy. Tara explains her findings on where current systems have plateaued, what existing technology already allows producers to measure, and why individual ewe performance will be one of the next major productivity levers.
