Roy Willan

“Winter Star II on the milking platform has given us options to make more silage that is better quality than previous years. It keeps growing well into August and September and maintains its quality, enabling us to turn low producing paddocks into high performing paddocks within 12 months. The extra production has certainly paid for the cost of the seed.”
