Description
  • Sub-indexes were constructed for bulls of the Holstein breed according to groups of production traits - production index for milk (IPH), sub-indexes for reproduction (IRH), longevity (IDH), health resistance (IOH) and fitness (IFH). Every index for selection for a group of traits applies all available information - breeding values for traits of milk performance, fertility and linear type trait classification. The sub-indexes were compared with the total index (SIH). The accuracy of total selection index(SIH) was 69.30%, the accuracies of the other indexes were as follows: IPH 83.32%, IRH 56.04%, IDH 9.80%, IOH 15.57% and IFH 9.86%. All of the indexes were stand-ardised to have the mean 100 and standard deviation 12. Simplified index ZSIH was developedas a sum of IPH, IRH and IDH; its correlation with the total index is r = 0.992. If IPH is used, the values of secondary functional traits decrease. The use of IDH, IOH and IFH results in a decrease in milk performance. Selection differences, i.e. chan
