Episode 144: The Regenerative Blood Business with Gavin Heywood

Regenerative Agriculture Podcast

Gavin Heywood is an Australian farmer and entrepreneur from New South Wales, whose family has worked on the same land for over 120 years. He runs a unique business, Serum Australis, which supplies animal blood for medical diagnostics, research, and commercial applications while managing his farm with holistic grazing practices.
Gavin’s journey into the blood industry began with his background in laboratory work and an early attempt to sell goat serum, which led to his discovery of a larger market for horse blood. Alongside his business, he is committed to regenerative agriculture, using time-controlled grazing to restore degraded farmland, increase biodiversity, and improve soil health.

In this episode, John and Gavin discuss:

• Running 250 horses in a single mob using time-controlled grazing

• Supplying blood and serum for hospitals, universities, and research labs under strict ethical guideline

• Gavin’s years of trial and error building a successful niche business

• Using horses as a tool for breaking up soil, regenerating pastures, and fostering tree growth

• Creating ecosystem improvements, including better water retention and increased plant diversity

• Gavin’s plans to expand his regenerative efforts by transitioning toward cattle and sheep grazing
