New Zealand Dairy Productivity: Why Fewer Cows Produce More Milk
The herd count is the wrong headline New Zealand’s dairy herd has fallen from its 2014/15 peak, and that fact gets repeated so often that it starts to sound like a story about decline. It isn’t that simple. Herd size is an input. The measure that actually pays the bills is milksolids per cow, and that number has kept rising even as total cow numbers eased lower.
