Owl Farm case study - Herd genetics
Read how genetic selection keeps Owl Farm's herd among the nation's best.

This page from Owl Farm, the Waikato demonstration dairy farm run jointly by St Peter's School and Lincoln University, describes how replacement calves are selected, fed colostrum and reared through to weaning.
It covers vaccination and DNA sampling timing, growing calves on chicory once weaned, regular liveweight monitoring against puberty targets, and the mating programme used once heifers are out grazing.
