‘Scharrel’ (free range) pigs: Carcass composition, meat quality and taste-panel studies

Abstract

Carcass conformation, meat quality, fatty acid patterns of backfat and sensory quality characteristics (tenderness, juiciness, smell and taste) of scharrel (free range) pigs and animals from intensive fattening systems were compared. Both groups of pigs consisted of 80 animals, which were slaughtered in batches of 20 pigs per group. The measurements included hot carcass weight, HGP, pH and FOP measurements and a score for intrathoracal fat deposition, all performed early post mortem, and marbling, colour, drip and cooking loss and Warner-Bratzler shear force measurements in loin chops after 1 and 3 days of storage at 4°C. Furthermore, 25% of the carcasses were used in taste-panel analyses. The feed rations used for these 25% of the pigs and their backfat samples were analysed for fatty acid patterns. The overall meat quality of scharrel pigs was not significantly different from that of pigs from intensive fattening systems. W-B shear force values of scharrel pigs were slightly higher. However, this did not coincide with differences in panel tenderness scores. The analytical panel assessed minor differences in taste and smell. The inconsistency of the descriptions concerning these differences did not allow any conclusions. An increase in the amount of linolenic acid was observed in the scharrel pigs' backfat.
