Impact of selection of dual purpose cattle on secondary traits

Original language description

The selection of dual purpose cattle is simulated by selection indices. In includes milk (amount of milk milk protein) and beef production (daily gain valuable meat cuts growth capacity feed conversion) and secondary traits (fertility longevity mastitiscalving difficulty). Partial breeding values for traits are combined into selection indices. Economic values of 1 1.5 2 and 4 multiples of results of the profit function are assigned to secondary traits in the indices. In the case of basic variaasic variant the genetic gain of milk production is 58 kg and effects of selection on milk and beef production and secondary traits are at a ratio 81:20: -1 The most important traits in the indices are amount of milk feed conversion milk protein content and dailygain., Most secondary traits show worse values., In the case of 1.,5 multiple overvaluation of secondary traits the genetic gain is 51 kg milk and ratios of selection are 72:19:9., In the case of 2 multiple overvaluation the genetic gain
