Dairy farmer: Gary Zweck
Region: South Australia
The South Australian dairy farmer previously outsourced breeding, using a consultant to correctively mate his family’s Holstein herd.
He was pleased with the way his herd was milking but wanted to take the hassle out of pouring through glossy breeding magazines and catalogues.
As part of the Improving Herds project four years ago, Gary and his wife Ros were introduced to selecting bulls using the Balanced Performance Index (BPI).
The BPI reflects the economic drivers for a range of Australian dairy farming systems: production, health and fertility, type, workability and feed efficiency.
