The frequency of hyperprolific sows of Large White Yorkshire and Landrace was investigated in the populations consisting of 1778 and 1823 sows, respectively. The distribution of sows with different number of live-born piglets points at the number of hyperprolific sows, being from 1.0 to 1.8, highest percentage of sows is in the class from 6 and 7, i.e., 8 and 9 live-born piglets respectively. The results of the number of still-born piglets show a reduced embryo mortality in hyperprolific sows in relation to the sows with lower number of live-born piglets. The results of the experiment show the necessity of making a nucleus part of the population and the application of BLUP method in selection of litter size.
