Differentiation of fatteners carcass quality traits depending on GH/MspI polymorphism Zróżnicowanie cech jakości tuszy tuczników w zależności od polimorfizmu GH/MspI Summary. The aim of the present study was to analyze the traits of fattening and slaughter performances of fatteners according to GH/MspI polymorphism. A total of 369 fatteners from one herd were investgated. The fatteners belong to five different breed groups: The frequencies of C and T alleles of GH/MspI polymorphism were,

Comparing the numbers of individuals in GH/MspI genotype gropus and the number calculated theoretically according to the Hardy-Weinberg law, no statistically significant differences were found. The conducted studies demonstrated a statistically significant influence of the breed group on the examined traits of fattening and a slaughter performances and a statistically significant interaction between the breed group and GH/MspI polymorphism for loin eye area. It was shown that GH/MspI polymorphism itself does not differentiate in any statistically significant way any of the examined fattening and slaughter performances of studied fatteners.
