摘要

This study evaluated the correlation of carcass meat content with the development of the reproductive system in sexually immature gilts of Polish Large White (PLW) and Polish Landrace (PL) breeds. The results, obtained from three groups (I, II, III) of gilts differing in lean meat percentage, indicate an effect on fattening and slaughtering traits as well as on the morphometric characteristics of the uterus. There were statistically significant differences in the values of fattening and slaughtering traits in the groups of gilts tested. Studies on the relationship between morphometric characteristics of the reproductive system and carcass meat content showed that there was a correlation between the weight of the uterus with and without the broad ligament and the meat content of the carcass. The weight of the uterus was higher (P ≤ 0.05) in gilts with lower meat content. The negative influence of high gilt meatiness on development of the reproductive system was more pronounced in PLW gilts.
