Abstract
The possibilities of an indirect breeding influencing of the feed effi ciency were investigated The regression coefficients between the trait s of efficiency gross efficiency, net efficiency, part of energy used for milk synthesis, energy yield per kg metabolic body weight and the traits milk yield feed intake, back fat thickness, body weight at seve ral times, body measurements are presented and discussed.
