The aim of the study was to perform a randomized assessment of slaughter material in the form of intensively farmed turkeys obtained by large poultry slaughter and meat processing plants. The assessment involved determining the slaughter value and physical characteristics of the meat. Samples (23 male and 12 female turkeys) were collected from the processing line of a large commercial poultry processing facility, and hybrid turkeys of a BIG 6 heavy breeding line came from different producers. Sex had an effect (p ≤ 0.01) on the slaughter traits of the BIG 6 heavy turkeys. Turkey toms were characterized by higher body weight and dressing percentage. The preslaughter weight of BIG 6 turkeys has a large effect (p ≤ 0.01) on the extent of technological losses and dressing percentage. The meat of BIG 6 turkey toms and hens exhibited highly favourable physical parameters, in particular a good concentration of hydrogen ions 20 min and 2 h and 24 h post mortem (pH20, pH2h, pH24h), which shows that the meat ageing process was correct. The results obtained indicate that pH and electric conductivity are among the most important traits to be used for quick and proper evaluation of the meat from BIG 6 turkeys. BIG 6 heavy turkeys, farmed intensively following the recommendations for this type of production, provide very good slaughter material.
