Purpose of this paper was to determine fertility traits heritability coefficients of the sows (number of live born, total number of born, stillborn and reared piglets in the litter) and interconnections between these traits. Heritability coefficients were low and averaged in interval from h2 = 0,056 for number of reared piglets in litter to h2 = 0,142 for total number of born piglets in litter, which is in accordance with heritability values for reproductive traits. Genetic interconnections of these traits had wide variation interval and averaged from r = - 0,221 between number of still born and reared piglets in litter to r = 0,947 between total number of born and number of live born piglets in litter. Coefficients of phenotype correlation varied in interval from r = -0,162 between number of still born and number of live born piglets in litter to r = 0,909 between total number of born and number of live born piglets in litter.
