How do you actually pick which heifers to keep? For many, selecting the top ones is easy, but it's those middle ones that are hard to choose between. 

For this week's guest, Geoff Hayes, the answer is genomics. Geoff and his wife Belinda started their Angus stud just 5 years ago, but began their genomic journey early, not wanting to pick bulls on looks alone from the very beginning. 

"I was hesitant just to go and pick them visually," Geoff explains. "We need to put some science into it."

They began with a base genomic test across a random selection of purchased cattle, which showed them that they were fine for IMF, but needed to increase ribeye area, and that became the main basis of their early selection focus.

Over time, that focus shifted. Rather than just chasing carcass traits, they started looking for sires out of cow families with longevity in the background. This introduced more of a focus on the maternal and stayability traits. 

Geoff still tests his own weaners before deciding which ones to keep and that same mindset is now extending to heifers, with Geoff part of MLA's heifer PDS project. The project involves genotyping heifers, alongside visual measurements to help guide replacement decisions. This project is ongoing, and we will have results to share in the coming years. 

Mark and Geoff finish by talking about where the beef industry is headed with record property and beef values, as well as the possibilities of new technology just around the corner.

Optimised Heifer Selection is a Producer Demonstration Site (PDS) project funded by Meat & Livestock Australia and facilitated by neXtgen Agri. Geoff Hayes is a core producer demonstration site for this project.
