  • Inside the Merino Wether Trials: Benchmarking Bloodlines with Dr. Sue Hatcher and Phil Graham

    Inside the Merino Wether Trials: Benchmarking Bloodlines with Dr. Sue Hatcher and Phil Graham
    Dec 8 2025
    Join us for another thought-provoking episode of Genetics in the Paddock with Emily, as we dive into one of the longest-running and most influential sources of independent Merino genetics information: wether trials.

    In this episode, Emily is joined by Phil Graham from Graham Advisory and Dr Sue Hatcher from Makin Outcomes to unpack why this decades-old approach is re-emerging as a powerful decision-making tool for today’s sheep producers. Together, they explore the origins of the combined wether-trial analyses stretching back to the 1990s, why producers have consistently driven demand for independent data, and how these trials continue to provide deep genetic insights beyond what you can see from on-farm performance alone.

    From benchmarking bloodlines and understanding genetic variation in key traits like fibre diameter and clean fleece weight, through to navigating the well-known trade-offs between production traits, Phil and Sue break down what the results really mean for flock improvement. We also step through how a wether trial actually works, from entry to final data collection, and discuss why the analysis is done on a ewe-flock basis, how producers should interpret results given changing breeding objectives, and the influence of environment on data interpretation.

    Finally, we look ahead to the future of wether trials and where the next 10–15 years of industry-led benchmarking could take us. Whether you’re a producer, advisor, or simply keen to understand how independent genetic comparisons can guide better breeding decisions, this episode is a must-listen.

  • The Genetics Behind the Microbiome: Predicting Performance with Microbes with Dr. Andrew Lakamp (Pt.2)

    The Genetics Behind the Microbiome: Predicting Performance with Microbes with Dr. Andrew Lakamp (Pt.2)
    Nov 9 2025
    Join us for another deep-dive episode of Genetics in the Paddock with Emily, as we continue exploring one of the most exciting frontiers in livestock science: the microbiome. In Part 2, Emily is again joined by livestock geneticist Dr. Andrew (Drew) Lakamp to look beyond what the microbiome is and focus on what it can do for breeding decisions.

    In this episode, we dig into how an animal’s genetics influence the microbes in their gut and eye, what “microbiome-mediated genetic effects” actually mean, and how genome + metagenome data could improve breeding value predictions.

    We also unpack practical questions for industry: When should samples be collected? How do sequencing methods differ? And could microbiome data one day be incorporated into EBVs and selection indexes?

    Whether you’re a producer, advisor, researcher, or simply curious about where the next decade of breeding innovation is heading, this episode offers a glimpse into the future of microbes as measurable, selectable traits.

  • The Genetics Behind the Microbiome: Why Your Livestock’s Microbes Matter with Dr. Andrew Lakamp (PT. 1)

    The Genetics Behind the Microbiome: Why Your Livestock’s Microbes Matter with Dr. Andrew Lakamp (PT. 1)
    Oct 26 2025
    Join us for another thought-provoking episode of Genetics in the Paddock with Emily, as we explore one of the most fascinating and fast-moving frontiers in animal science — the microbiome. In this episode, Emily is joined by Drew Lakamp, a livestock geneticist helping unravel how the billions of microbes living in and on our animals influence productivity, health, and even breeding potential.

    Together, they unpack what the microbiome actually is, how it differs from the animal’s own genome, and why producers should care. From feed efficiency and disease resistance to fertility and welfare, we look at how microbial communities could one day be treated as traits in their own right.

    Whether you’re a producer, advisor, or simply curious about the hidden biology shaping animal performance, this episode is a must-listen for understanding the role of microbiomes in modern livestock breeding.
