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 'Optimised Heifer Selection' project, which focuses on combining genomic tools with visual assessment to improve 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.

'Optimised heifer selection – Integrating genomic selection tools and on-farm assessments to maximise lifetime productivity' is a Meat & Livestock Australia Producer Demonstration Site project.
