The dairy industry is heading for a revolution and farmers should be taking action to future-proof their businesses now, Keith Woodford says.
Growing international demand for A2 milk was a major threat to the industry, Woodford told about 50 people at a Rural Business Network (RBN) meeting in Hawera.
A2 milk comes from cows that naturally produce milk with the A2 version of beta-casein, rather than the A1 version of the protein, which can impact the digestive system and has been linked to ailments including irritable bowel syndrome, eczema and diabetes.
A farm consultant and former agribusiness professor at Lincoln University, Woodford is the author of Devil in the Milk, a book on the A1 versus A2 debate. He said New Zealand farmers needed to start working towards converting their herds to 100 per cent A2 animals.
