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 ♀SLx♂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 (lt) 0.001) for all studied traits, whereas the effect of genotype was not established (P>0.05).
Cilj ovog istraživanja je da se utvrdi uticaj genotipa grla, godine merenja i rođenja grla na osobine performans testiranih nazimica: uzrast na kraju testa (UKT), životni dnevni prirast (ŽDP), debljina slanine 1 i 2 (DSL1 i DSL2), dubina leđnog mišića (MLD) i procenjeni udeo mesa u trupu. Od ukupnog broja (n=3600) istraživanjem je obuhvaćeno 1709 grla genotipa ŠL i 1891 grla genotipa ♀ŠLx♂VJ. Po godini rođenja testiranih nazimica distribucija je bila sledeća: n2006=296, n2007=895, n2008=934, n2009=803, n2010=589 i n2011=83 nazimice. Dok je po godinama testiranja distribucija nazimica bila sledeća: n2007=682, n2008=875, n2009=962, n2010=697 i n2011=384 nazimice. Za sve ispitivane osobine utvrđen je uticaj godine merenja i godine rođenja (P (lt) 0.001) dok uticaj genotipa nije utvrđen (P>0.05).
