How do you breed a lamb that consistently delivers a better eating experience?
For decades, sheep producers have been selecting for traits they could easily measure, including growth, fertility and lean meat yield. But eating quality has remained far more difficult to quantify, despite being one of the biggest drivers of consumer satisfaction and long-term demand.
On this episode, Mark chats with David Packer, Program Manager – CarcaseValue at Meat & Livestock Australia, to explore how advances in meat science are changing that.
David explains why carcase value is ultimately driven by two key components: eating quality and yield. Rather than maximising one at the expense of another, he highlights the importance of balancing both alongside productivity traits within a breeding objective.
David also explains the biology behind meat quality, from intramuscular fat and tenderness through to electrical stimulation, cold shortening and physiological maturity. He also discusses why consumer taste panels remain the benchmark for eating quality research, and how new technologies are finally making it possible to measure commercially important traits at processing speeds.
Mark and David also discuss the results of the 2026 LambEx Carcase Showcase, where more than 5,300 lambs from 52 properties were benchmarked across four states and at multiple processors.
The findings highlight substantial variation in eating quality and lean meat yield within every breed and production system, reinforcing that every producer has an opportunity for genetic improvement rather than identifying a single "best" breed or finishing system.
As carcase feedback becomes more widely available and objective measurements continue to improve, producers are gaining access to information that has the potential to refine breeding objectives, validate ram purchasing decisions and capture greater value throughout the supply chain.
Whether you're interested in genetics, processing, meat science or producing lambs that better meet consumer expectations, this episode shows just how rapidly objective carcase measurement is reshaping sheep breeding.
