Investigations were carried out on 97 samples of muscuhts longissimits dorsi cut out from carcasses of commercial fatteners 24 h after slaughter. The control group consisted of wbp pure-bred fatteners, whereas the experimental group comprised hybrids obtained from crossing Naima sows with P-76 boars. No carcasses with quality defects of DFD or ASE type were recorded in either of the examined groups, while the proportion of PSE meat in the experimental group amounted only to ca. 1.5%. Favourable results of physicochemical and technological examinations as well as of sensory evaluation of meat and smoked loin indicate that the examined hybrids can be treated as good raw material for the production of both culinary meat and for processing.
