Episode Details

What if everything you think you know about dairy genetics is wrong? This week, we dive deep into the remarkable story of Larenwood Farms in Drumbo, Ontario - a 60+ year closed herd operation that's proving the dairy industry's obsession with purchasing elite genetics is fundamentally flawed. Chris McLaren and his family have achieved 13,100 kg milk averages, earned three consecutive national DHI awards, and obtained the coveted Holstein Canada Master Breeder shield - all without buying a single animal in over six decades. This isn't just a farm profile; it's a masterclass in why internal breeding development crushes expensive genetic purchases every time.
