If you want to know about sheep genetics in New Zealand, our guest this week, John McEwan, is the person to ask. John has been involved with genomics “since before genomics was a thing.”

From discovering key reproductive genes and rolling out DNA parentage, to the sequencing of the sheep genome and the industry adoption of genomic selection, John takes us through the milestones that have shaped New Zealand sheep breeding.

Tune in today to hear where we're heading next.

When you think of a "Modern Merino", what comes to mind? For our guest this week, Willera Merino stud principal Simon Coutts, it means a sheep that works for your business, regardless of the weather or market conditions.

Simon explains Willara's breeding philosophy, which focuses on developing a "modern Merino" that is multi-dimensional and provides multiple income streams from high-value wool, prime lamb, capital stock, and mutton.

Simon and Ferg chat about the three Willera properties and how they work together, as well as the genetic progress they have made by mating ewe lambs and ram lambs.

A great insight into a very forward-thinking breeding programme.

Willera are having their 2025 ram sale on Friday 29th August

Simon Saunders is one of the original farmers behind Headwaters and runs the elite ewe flock at his farm, Stag Valley. In this episode, he discusses how the breeding program has evolved, what it takes to deliver consistency at scale, and the future of the Lumina lamb programme.

If you're wondering how to extract more value from your sheep operation or thinking about speciality lamb production, then this episode is not one to miss!

This week, we’re chatting about the differences between US and NZ sheep production systems with Dr. Whit Stewart, an Associate Professor and Extension Sheep Specialist in the Department of Animal Science at the University of Wyoming.

Whit has spent the last year on a sabbatical in New Zealand, learning and absorbing as much as he can about sheep farming here. Because of this, he has some great insights into the comparisons between systems as well as what we do well, and what we could do better at.

He and Ferg chat about predator pressure, grazing public land, the structure of the US lamb supply chain, and what it's like farming in a country where golden eagles can take 40% of your lamb crop. Whit also chats about what he’s learnt here in NZ. Our use of tools like FarmIQ, a strong export focus, and top-notch forage management are our strong points, according to Whit. And he also shares what he thinks we could learn from the US in return.

It’s a great conversation with someone who is very passionate about building better sheep businesses, regardless of where he is on the globe!

This week we’re (belatedly) joined by Jack O’Connor, winner of the 2025 Zanda McDonald Award. Jack lives and works on the family’s fourth-generation mixed farming operation, Oxton Park, in southern NSW.

He and Ferg discuss his career so far and why, for Jack, business success comes down to the people and community he works alongside. And with 20 staff, 15 properties, and both livestock and cropping enterprises, that focus on people is essential!

They also chat about the importance of professional development, leadership, and mentorship. It’s a great listen for anyone thinking about the future of agriculture and how to bring their team along with them.

We're back on the genetic evaluation theme with Peta Bradley, Operations Manager at Sheep Genetics, to talk all things sheep genetics and the exciting changes that are happening at MLA in terms of bringing the two LAMBPLAN databases together.

Peta also discusses the evolution of the Sheep Genetics genetic evaluation over the years, the crucial role of genomics as well as phenotypes and a current reference population, as well as her ice-swimming journey!

This week, we’re joined by Jason Archer, Head of Genetics at Beef + Lamb NZ, to discuss the untapped potential of genomics in livestock.

Jason has spent his career working across beef, sheep, and even deer between Australia and New Zealand. He and Ferg chat about where genomics is taking us, why some of our current systems are holding things back, and what it might take to unlock faster progress in traits like feed efficiency and methane.

• Why genetics is still underused in livestock breeding
• How genomics is shifting from enhancement to substitution
• The science (and logic) behind feed efficiency and methane
• What it takes to unlock genetic progress at a national level
• How genomics can impact commercial farmers

In this episode, Ferg is chatting with Sharon Paterson from Waikaka Station in Southland, NZ. Sharon is very passionate about her flock of Texels and chats with Ferg about her selection process and her very rigorous culling criteria for structure and litter size, which have led to a uniform and productive line of sheep.

Ferg and Sharon discuss

• How structure improves stayability
• How culling singles over the years has improved fertility.
• How improved survivability counteracts a lower scanning percentage
• The GDF9 gene
• How selecting on structure can impact carcass traits
• Paterson Park and Gardens
