John Cann

John joined the CMC ruminant specialist team in 2015, bringing with him a wealth of practical experience and in-depth knowledge of dairy nutrition. Alongside his role at CMC, he also runs a family-operated robotic dairy farm in Devon—giving him a valuable dual perspective as both advisor and farmer. As John puts it,

"I see both sides of the fence."

His passion for farming began early, leading him to leave school to work on a large dairy unit before securing, with his wife Tracey, a 15-year tenancy on a 112-acre council farm in Tavistock. After building a successful 150-cow herd, they relocated to Highampton, where they began contract rearing and John took his first steps into feed sales. In 2013, they re-established their milking herd — this time using robots.

John is known for his honest, straightforward approach and his commitment to delivering practical, results-driven nutritional advice. He has earned a strong reputation within the industry for combining scientific knowledge with real on-farm understanding.

At CMC, John works closely with Karen to develop and deliver technical training for our sales team, ensuring our customers benefit from the latest research and innovations.

Outside of work, John enjoys farming with his family and continuing his lifelong passion for British agriculture.
