This study examined carcass and meat quality parameters in growing/finishing pigs fed unconventionally versus the concentrate-based system. Ninety-six, 12 wk old pigs ($34{\pm}SD0.3kg$) were randomly divided into three groups, assigned to one of the three dietary treatments: standard complete concentrate mixture, conventional (C diet); unconventional, steamed potato-green forage-concentrate based diet (U diet), and unconventional basal diet+herbage mix (UH diet). Pigs fed U diet showed lower dressing percentage, meatiness, loin eye area, and weight of pork neck ($p{\leq}0.05$), but their carcasses were significantly ($p{\leq}0.05$) longer and had increased backfat depth ($p{\leq}0.05$). There was no impact of the diet on the meat content of dry matter, crude ash, acidity, and colour parameters of m. longissimus. Unconventional feeding significantly ($p{\leq}0.05$) elevated water the holding capacity of m. longissimus and slightly improved the sensory attributes analysis of meat. The addition of herbs resulted in increased loin eye area ($p{\leq}0.05$), decreased fat content ($p{\leq}0.05$) in m. longissimus, and tended to improve some sensory attributes of meat. There were significant gender differences in response to all diets. There were significant diet${\times}$sex interactions for some measured variables, but there were no clearly identifiable trends with regard to any specific carcass or meat parameters. Feeding unconventional diet to pigs may offer better culinary attributes of the meat, and improve some technologically important characteristics of pig carcass, but may negatively affect some carcass or meat parameters.
