The aim of this study was to evaluate and compare the quality characteristics, chemical composition and lipid profile of lamb meat from Italian (Biellese and Sambucana) and German (Texel-Merino-Blackhead-Charollais [TMBC]) breeds reared in extensive and semi-extensive production systems. Meat samples from 89 animals were analysed. The meat of the lambs from semi-intensively reared Biellese, and extensively reared Sambucana and TMBC breeds produced lean meat, with slightly higher intramuscular fat content in TMBC. The latter also produced meat of darker colour (P<0.05) and higher protein content (P<0.05). The meat of Sambucana lambs presented the lowest total cholesterol content (P<0.05). The fatty acid profile of the meat showed a clear advantage of both extensively reared breeds, which had substantially lower proportion of saturated (SFA) but higher of polyunsaturated fatty acids (PUFA), particularly n-3 (P<0.05). The beneficial effect of the extensive rearing conditions was associated with lower n-6/n3 ratio, and atherogenic (AI) and thrombogenic (TI) indices, thereby suggesting that production system can be used successfully to modify the fatty acid profile to achieve a positive effect for the human health.
