Value of traits in beef cattle breeding

Popis výsledku v původním jazyce

An index has been devised for the selection of bulls in beef breeds. The overall breeding objective was to improve direct and maternal effects on the ease of calving, growth and carcass value. Correlated indirect responses of selection were also examinedin calf losses, fertility and cow longevity. The sources of information used were breeding values that are currently calculated in a routine way in the Czech Republic ? direct and maternal effects for calving ease and growth (10 breeding values), breeding value for daily gain of bulls at performance-test stations (1 breeding value) and breeding values for the type traits of young animals (10 breeding values). Five indexes were constructed according to the number of information traits included. Economicvalues of traits in the breeding objective were calculated using discounting rates of 10% and 0%. The accuracy of selection according to indexes for aggregate genotype ranges from 30 to 46%. The discounts of economic values used did not
