Abstract

The aim of this study was to evaluate the fatty acid profile and health lipid indices of meat from 3 Polish local goose varieties (Romanian–RO, Pomeranian–PO, and Subcarpathian–SB) and the commercial cross White Kołuda goose (W31). Birds were fed ad libitum with the same complete feeds until 17 wk of age. The geese (n = 72) with body weight close to the arithmetic mean in particular flock were fasted for 12 h and slaughtered in an experimental slaughterhouse (18 females in each flock). Carcasses were stored at 2 to 4°C for 24 h. The breast muscles (m. pectoralis major) were cut out from the left side of carcass, separately vacuum-packed, and stored at −80°C until analysis. Fatty acid profile of meat was determined by gas chromatography and health lipid indices were calculated. The W31 muscles had a higher percentage of C 18:0 and a lower of C 16:0 than those of RO, PO, and SB geese. The W31 muscles were characterized by a significantly higher proportion of monounsaturated fatty acids (46.5%) than remaining ones (43.28%–PO, 43.38%–SB, and 44.24%–RO). The lowest proportion of polyunsaturated fatty acids was established for W31 muscles (22.05%). The breast muscles of RO, SB, and PO had more favorable polyunsaturated n-6 and n-3 fatty acid (PUFA)/ saturated fatty acid (SFA) ratio (0.85, 0.82, 0.83, respectively) than W31 geese (0.72). The current findings showed that UFA/SFA, PUFA/SFA, and PUFA n-6/n-3 ratios in RO and SB muscles were within the optimum values for human diets. No significant differences were observed in the atherogenic, thrombogenic, and hypocholesterolemic/hypercholesterolemic indices between the analyzed muscles. Commercial W31 geese breast muscles showed a lower value (43.90%) of peroxidizability index (PI) compared to SB (52.88%), PO (53.93%), and RO (53.47%). However, the higher values of the PUFA/SFA and PI in the meat of SB, PO, and RO birds may indicate a higher prohealth value of their meat.
