The aim of the thesis was to analyse the reproductive parameters of the CLW and CLWxCL sows group in selected breeding group (CLW - Czech Large White, CL - Czech Landrace). Sows, compared to gilts, had more all born piglets born after 100 services (by 118 piglets more after 1st insemination and 116 piglets more after all inseminations). The CLWxCL sows gave birth to 0.10 more all born piglets and 0.21 live piglets more. The highest number of piglets, all and live, was born in the 4th parity. The correlation coefficients between the age at the 1st service and the number of all resp. live-born piglets were low. Only 0.1 live piglets were born to CLW sows with weaning to service interval (WSI) from 5 days compared to WSI to 4 days. In CLWxCL sows, more live-born piglets showed sows with WSI to 4 days compared to sows with WSI from 5 days. The difference was higher, namely 0.8 piglet (P < 0.05). In the case of CLW and CLWxCL sows was confirmed a statistically significant difference in the number of live-born piglets between the sows with a gestation length from 116 days, up to 114 days and 115 days. Most of the piglets were born after AMD 74 boar and the lowest number after AMD 101 boar.
