Abstrakt

Production index for milk (IPH) and sub-indexes for reproduction (IRH) and longevity (IDH) were constructed for practical application. Using IOH and IFH is not recommended because of no availability of direct indicators for health in animal recording andthis trait is selected indirectly. The constructed indexes are substantially influenced by population genetic and economic parameters.
