Loin muscle volume and hind leg muscle volume measured by computer tomography are economically valuable traits in rabbit breeding. Hence, genetic parameters were calculated to these new selection criteria, and a two-trait selection index was created in order to modify the current selection process of the Pannon large rabbit breed. The evaluated animals (n = 312) were randomly selected from 2014 and 2018, and the total number of animals in the pedigree file was 2758. Loin muscle volume (LMV) and hind leg muscle volume (HLV) were analyzed in a two-trait animal model. The estimated heritability for LMV was h2 = 0.4 and h2 = 0.42 for the HLV respectively. The selection index was created with desired gains by improving each trait in the selection criteria with one additive genetic standard deviation and the final index was Z transformed. Correlation coefficients between the index and the examined traits were high, 0.86 for LMV and 0.87 for HLV, thus this method could be announced into the breeding program.
