The aim of the thesis was to analyze the marshaling gilts for breeding. The experiment contains two groups of gilts. First group included gilts from own production, second gilts were purchased. Main goal was evaluation of pregnancy length, age in first pregnancy, in first due date and assess the numbers all born piglets, live- born piglets, stillborn piglets and mummified piglets in the litter from the first parity sows. Gilts were also analyzed for reproduction, depending on breeding age or age in purchasing period. According to that results, we did evaluation for selected indicators of reproduction like gravidity length, all born piglets, live-born piglets, stillborn piglets and mummified piglets in a litter. As we can see from results, the highest number of all newborn piglets achieve gilts from own production, namely 13,70 DC. Gilts in own production gave us higher number of live born piglets, 12,74 DC but they have lower number of stillborn piglets, specifically 0,61 DC. Gilts, which were purchased, have lower number of mummified piglets 0,04 DC. The length of gilts pregnancy were the same in both groups, average is 115 days. First service of gilts in own production was 238,02 days, in group of purchased gilts it was 247,65 days. Averadge age for first birth in own production group was 353,66 days, purchased group 363,32 days.
