FATTY ACID COMPOSITION OF LAMB MEAT FROM ITALIAN AND GERMAN LOCAL BREEDS
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
