Genetic parameters (heritability coefficients and genetic correlations) of the type of calving, number of stillbirths and birth weight have been evaluated in the population of Holstein Friesian cattle breed. Data sets have been analysed by means of the Mixed Least Square Model (LSMLMW). Besides a random effect of bull-sires, the model has also included the fixed effects of farm, season, sex, the evaluation of viability of calves and types of birth. Estimated heritability values and heritability errors for the type of calving (TC), number of stillbirths (SB) and birth weight (BWT) were low: 0.190 ± 0.062; 0.018 ± 0.006 and 0.149 ± 0.051, respectively. Heritabilities of the analysed traits were evaluated on the grounds of the calves` bull-sires additive value (direct heritability). The values of the genetic correlation coefficients between examined traits ranged from - 0.251 (correlation between the type of calving and number of stillbirths) to 0.340 (correlation between the number of st...illbirths and birth weight).
Genetski parametri (koeficijent heritabiliteta i genetske korelacije) tipa teljenja, broja mrtvorođene teladi i telesne mase pri rođenju ocenjeni su u populaciji krava holštajn frizijske rase. Setovi podataka analizirani su putem mešovitog modela najmanjih kvadrata (LSMLMW). Model je pored slučajnog uticaja bikova-očeva obuhvatao fiksne uticaje farme, sezone, pola, ocene vitalnosti teladi i tipa rođenja. Ocenjeni heritabiliteti i njihove greške za tip teljenja, broj mrtvorođene teladi i telesnu masu pri rođenju bili su niski i iznosili su: 0,190 ± 0,062; 0,018 ± 0,006 i 0,149 ± 0,051, odgovarajuće. Heritabiliteti analiziranih osobina ocenjeni su na osnovu aditivne vrednosti očeva teladi (direktan heritabilitet). Koeficijenti genetskih korelacija između ispitivanih osobina imali su vrednosti od -0,251 (povezanost tipa teljenja i broja mrtvorođene teladi) do 0,340 (povezanost broja mrtvorođene teladi i telesne mase pri rođenju).
