Objective of this research was to establish the effect of animal genotype, year of measuring and birth on traits of performance tested gilts: age at the end of the test (AET), life daily gain (LDG), back fat thickness 1 and 2 (BFT1 and BFT2), depth of back muscle (MLD) and assessed share of meat in carcass. Of total number of animals (n=3600) included in the research, 1709 animals were of genotype SL and 1891 of genotype male SL x female LY. In regard to the birth year of tested gilts, the distribution was following: n2006=296, n2007=895, n2008=934, n2009=803, n2010=589 and n2011=83 gilts. In regard to testing year, the distribution of gilts was as follows: n2007=682, n2008=875, n2009=962, n2010=697 and n2011=384 gilts. The effects of test year and birth year were established (P is less than 0.001) for all studied traits, whereas the effect of genotype was not established (P is greater than 0.05).
