The aim of this study was to determine the influence of sow genotype, year of farrowing and parity on the number of live-born piglets. Fertility traits of sows were tested during fourteen years (from 2007 to 2020) in one pig herd/population. The study included 10159 sows, 4 genotypes: Landrace, large White, Landrace x large White and large White Yorkshire x Landrace. The sow fertility data set contained data on 36189 parities. Based on the obtained results, it was determined that the genotype of sows, year of farrowing and parity had a statistically highly significant (P <0.01) influence on the number of live - born piglets
