Getting maximum results from cattle and dairy herds is the theme of the first episode of Rural Delivery, a magazine-style series focussing on the agribusiness sector. The first story is set in Ruakura where a scientific trial into extended lactation using 56 Holstein-Friesian dairy cows has delivered promising results. Northland cattle farmer Alec Jack discusses the challenges of sourcing quality calves. There's a market update and a weather report, and presenter Roger Bourne interviews CEO-turned-educator David Irving about business learning centre The Icehouse, whose agribusiness programme upskills farmers.
