A Lifetime in Genetics
For more than 40 years, Southland farmer David Colhoun has dedicated his life to breeding rams that deliver where it matters most—on your farm. From humble beginnings as a shearer, David built Colhoun Genetics on hard work, practical know-how, and a passion for measurable improvement.
Today, Colhoun Genetics is recognised for proven Coopworth, Suftex, and Perendale sires bred for fertility, survival, growth, and carcass yield. Every ram is performance-recorded, DNA-tested, and selected with one goal: helping farmers improve their flocks and their bottom line.
With a no-auction, one-on-one approach, David takes the time to match the right ram to the right system. His philosophy is simple: “The success of my business is built on the success of my clients.”
Over four decades in sheep breeding, from genetic research to industry leadership.
