Sažetak

Data were obtained on 250 young Simmental bulls from performance test station during 6 successive years. The ayerage volumen of ejaculate was 3,43 cm and average concentration of spermatozoa was 775.5x 10⁶ (standard deviation = 186.5 x 10⁶). Systematic influences of environment were estimated by LSQ - method. The heritability estimated by model including influence of seasson was 0,44 for volumen of ejaculate and 0,58 for concentration of spermatozoa. The fenotypic correlation between concentration of spermatozoa and volumen of ejaculate was with low values but positive. The genetic correlation between these traits was zero.
