There is growing interest in the Australian dairy industry in the genetic improvement of the health of dairy cows. In Australia, there is minimal storage or export of health data off some on-farm software systems into industry databases to assist in the research or reporting of health traits. The Health Data for Healthy Cows (HDHC) project aims to get a better understanding of the extent of health data recording in the Australian industry by collecting health data from the 100 Ginfo (genomic reference) herds. Health data obtained from herd test centres totalled 275,729 records from just 46 out of the 100 herds. The four most recorded health diseases identified were mastitis, reproductive problems, lameness and metabolic disorders. Mastitis having the highest incidence with 20% of cows affected, followed by reproductive problems (12%), lameness and metabolic disorders (5% and 3% respectively). This project has provided an insight into what health information is actually being collected on farm and that there is a source of health data available which can be accessed and potentially used for the genetic improvement of health traits in Australian herds.
