Report prepared for Dairy Australia and DataGene by Dr John Morton BVSc (Hons) PhD MANZCVS (Veterinary Epidemiology), Veterinary Epidemiological Consultant with Jemora Pty Ltd.

The aims of this work were to describe daughter fertility breeding values in cows in a subset of Australian dairy herds, and to describe effects of two rates of increase in sire daughter fertility breeding values on 6-week in-calf rates under some simplifying assumptions. This report focusses on Holstein-Friesian cows (cows with breed code 'FFFF').
