The purpose of this thesis was to describe the transfer of genetic potential of sows in production sphere and evaluate concrete results in reproduction breeding sows Agricultural Society Kosova Hora. On large-scale farrowing sows were evaluated Doublovičky basic herd of sows, which consisted of 440 to 520 pieces. sows. The basic herd always has been about 35 nucleic sows (P 1065). The rest of the herd was an offspring of hybrids F1 (C 1023) program the PIC. The sows P 1065 were investigated causes selecting progeny namely: 1) For lack of development, which was evaluated from birth to breeding gilts adulthood. 2) The number and formation of the teats. For breeding were required to at least 12. They can not be crater, but well formed to have good piglets suck breast milk from them. 3) Reproduction in gilts were evaluated after conception periodic (cyclic) heat. The minimum requirement for the first 8 piglets which are born alive. For the basic herd was evaluated the age structure. It was incorporated into three groups and evaluated that, the largest selection of sows was for lack of milk production, limb injuries, poor breeding condition and the possibility of further embedding. The largest selection of sows takes place after the third to fifth lactation.
