Health disorders data collected from Australian dairy herds were analysed to estimate incidence levels and genetic parameters for some diseases traits and to examine the consequence of selection for Australian profit ranking (the economic index in Australia) and other economic traits on incidence of some diseases. Data on disease problems including udder, leg, reproductive and 'all disorders' were extracted from the Australian Dairy Herd Improvement Scheme database for cows that calved in 2007 and 2008 and were analysed fitting a linear sire model. The occurrence of disease problems was as high as 0.3 if 'all disorders' were put into one group. Five percent of the cows that calved showed leg..View full abstract
