In the present study for the first time, the associations were shown between RFLP/ApaI of the bovine CATD gene and the activity of cathepsins and several meat quality traits in a group of Polish Black-and-White, Charolaise and Simmental cattle. As the investigation was performed on 65 animals only, the findings presented might not be numerous enough to allow the proper definite conclusions concerning the influence of the mutation on activity of some lysosomal proteinases in different cattle genotypes and on meat quality traits.
