Genetic characteristics of economically useful features of Bulgarian Red cattle. III. Variability and heritability of external dimensions and their effect on milk yield and live weight of cows



Genetic characteristics of economically useful features of Bulgarian Red cattle. III. Variability and heritability of external dimensions and their effect on milk yield and live weight of cows



Zhivotnov"dni Nauki 11(1): 3-10



Mean values with SEM are tabulated for 9 dimensions and live wt. of the Bulgarian Red cows described in part I as well as for 93 Danish Red cows; and correlation coeff. between the 9 dimensions and live wt. and milk yield are presented. For the 2 groups of Bulgarian Red cross-bred cows taken together, the only significant correlation coeff. were those between chest depth and milk yield (+0.125; P < 0.001) and between diagonal body length and milk yield (+0.028; P < 0.05).
