We investigated linkage between age at the first insemination and the production through the exploitation. It was used only sows with the four liveborn litters. At the number of liveborn piglets we established a high significant variety (P is less than 0.01) between two groups (age of 321 days with 10.08 piglets and a group of 206.4 days old with the 9.04 piglets). Number of stillborn piglets were higher at the gilts which were elder at the first insemination. Gilts which were inseminated at the age of 185 to 216 days had a lower number of liveborn piglets and a higher number of feed days for one produced piglet. Between age at the first insemination and a measured traits we established negative correlations.
