At the end of the thesis are summarized the acquired knowledge, which contribute to the improvement of pig reproduction indicators. The monitored herd of rearing as of December 31, 2017 consisted of 800 sows (including pregnant gilts) and 230 unrestrained gilts.

DVOŘÁKOVÁ, Lenka
The aim of this thesis was to evaluate the reproductive performance of sows corporate program Czech PIC in a commercial breeding Ratiboř, Agricultural Cooperative Chyšky district Písek. The observed breeding herd was formed on December 31, 2016 with 119 sows and gilts. To evaluate the reproductive performance, the breeding-cows were divided into breeding sows inseminated and not inseminated, sow for 1st to 2nd litters (risk litters), 3rd to 5th litters (litter production) and for the 6th and higher. The breeding sows are frequently inseminated between 230th 269th day of life. In 2016, on average 25.2 live-born units were born per sow. The number of weaned piglets was at level of 21.8, it means the values were below the desired optimum. Good results were found in the length of intervening time (155.3 days), and the associated number of litters per sow. Sows reach 2.4 litters per year, and there is no problem with the beginning of rut after weaning. A rut mostly occurs on 4th and 5th day after weaning. The total cost for sows amounted to CZK 676,519.43 per year, when 1 kg of weaned pig costs CZK 53.75.
