Want to know more about meat-eating quality traits like IMF, shear force and marbling? Our guest this week, Dr Peter McGilchrist, is a leading meat scientist and professor at the University of New England, Australia, likely has the answers you're looking for. 

Peter and Mark talk all things meat-eating quality and how the red meat industry can move beyond commodity pricing by identifying premium quality products through genetics, processing, and proper animal handling. 

Peter and Mark discuss the importance of keeping an eye on IMF and shear force so that lamb doesn't "end up like pork," as well as the importance of early marbling and how we can genetically impact all three of these things. 

Pete also treats us to a quick biochemistry lesson explaining the science of cold-shortening as well as insights on recent trial work he's been involved with on the impacts of feeding sheep pre-slaughter on eating quality.

This podcast is a masterclass on the various aspects of red meat eating quality and is one not to miss!

Ever wished you could get breeding values on your commercial Merinos without having to record weights, dates or pedigrees?

This week, we’re launching neXtPredict, our brand new genomic tool that lets you go straight from DNA to breeding values with just a simple TSU sample.

Developed in partnership with Weatherbys Scientific, neXtPredict provides base genomic breeding values, parentage, poll/horn testing and a flock profile for Merino breeders. It’s powered by the MerinoSelect database and backed by MLA-funded research through AGBU and Sheep Genetics.

To announce the launch this week on the podcast, Ferg chats with Tamarah Luxton, Territory Manager at Weatherbys Scientific. Tamarah shares the story of Weatherbys’ journey from managing thoroughbred pedigrees in Ireland to providing cutting-edge genomic testing for livestock across Australia. 

neXtPredict has three service tiers, designed to suit everyone from large commercial breeders to data-driven operations wanting deeper insights.

• CORE gives you access to the neXtPredict Portal, where you can view gBVs, parentage, poll/horn, flock profiles and indexes, and filter or rank animals on standard industry indexes or generic neXtgen Agri indexes.
• PLUS includes everything in CORE, plus trait correlation analysis, the creation of custom indexes, and one-on-one support from the neXtgen Agri team.
• PRO adds long-term data storage, the ability to include non-genomic traits (like wool quality or dag scores), view multi-year data, and work directly with our consultants on testing strategies and optimisation.

What do you get when three sheep consultants, all podcast hosts, from Australia, England and Wales sit down in front of a microphone? You get a very entertaining, slightly chaotic, sheepy podcast!

This week, we're joined by Liz Genever and Nerys Wright to discuss the launch of OptiEwe UK as well as the challenges and opportunities faced by farmers over there. 

Liz, Nerys and Ferg chat about this summer's extremely dry weather, current lamb prices, shifts in farming practices (and the role of genetics in those shifts), as well as the difficulties of the ever-changing government policies.

Liz and Nerys are launching OptiEwe UK next week, and we're excited to continue working with them over the next few years!

Is drench resistance an issue on your property? Thanks to modern technology, we have tools at our disposal to help.

This week's guest is Ryan Luckman, vet and founder of DAGI, (Drench and Grazing Integration), an app that displays the risk of larval challenge/resistance risk for the paddocks on your farm, helping you make better grazing decisions. 

With the help of industry experts and the support of B+LNZ, Ryan has been building the DAGI (Drench And Grazing Integration) app over the past 2 years. 

Ryan talks us through the app and how it works on farm, as well as discussing the state of drench resistance in New Zealand. He and Ferg also discuss the topic of refugia and how this is all about the genetics of the worm population on your farm. 

Take a look at DAGI here:

Thousands of you listen to the podcast every week, but we've come to realise many of you don't know exactly what we do here at neXtgen Agri. 

In this episode, Mark, our host and CEO, takes to the mic and chats about all things neXtgen Agri and the services we provide to farmers across the globe. He shares how “farming in our hearts, science in our heads” drives everything we do.

From helping farmers lift genetic gain to building tools that make breeding decisions clearer and faster, Ferg goes through the work that keeps our team busy. We're out in the yards and around kitchen tables across Australia and New Zealand, as well as in meetings and boardrooms for multiple industry bodies, helping provide the knowledge transfer bridge between farmers and scientists.

If you have ever wondered what neXtgen Agri is really about, this is the episode that explains it all.

Our guest this week is Vicky Alexandrou, co-founder of Woven Optics.

Over the past eight years, Vicky has helped design and build a handheld microscope that lets you measure wool fibre diameter right there in the yards or shed. 

Instead of waiting for lab results, you clip a small sample, take a few quick images along the staple, and within seconds, the device tells you the mean micron, standard deviation, coefficient of variation, and comfort factor.

You can scan the sheep’s ear tag so the data is linked instantly, meaning decisions on classing, culling or breeding can be made on the spot with the most up-to-date information.

Vicky and Ferg also chat about the importance of industry collaboration, the current commercialisation of Woven Optics, and the future potential of AI in agriculture.

Woven Optics is available now through your local Heiniger representative.

What does leadership look like in agriculture today? For Felicity Taylor, Area Manager for Rabobank in Moree and a 2025 Zanda McDonald Award finalist, it’s about connection, community and supporting others to succeed.

In this episode, Felicity shares her journey from growing up on a cropping property to becoming the youngest area manager in Rabobank’s history. She talks about the rising costs facing farming, the challenge for young people to get started, and why she believes regional Australia offers opportunities that city life cannot.

What does it take to keep a sheep business moving forward? For our guest this week, Hamish Thomson of Moojepin Merinos, it’s a mix of genetics, management and never being afraid to try something new.

In the podcast, Hamish talks about the progress they’ve made since we spoke to him last, which was four years ago! 

They have been continuing to select for traits like growth, muscle and fat, as well as intensifying the focus to welfare traits such as dag, worms and, more recently, foot structure. 

He and Ferg also discuss the importance of ewe lamb joining and using ram lambs, containment feeding, and how they are tackling their most unproductive pastures.
