Fatty acids composition, lipids health indices and enzyme activities of longissimus thoracis muscle of six breeds of sheep produced on pasture in Northern region of Uruguay
Ácidos grasos, índices lipídicos de salud y actividades enzimáticas en el musculo longissimus thoracis, de seis razas de corderos producidos sobre pasturas en el norte de Uruguay
Resumen:
The determination of fatty acids composition of glycerolipids and glycerophospholipids of meat from longissimus thoracis of six breeds of lamb produced on pasture in Uruguay was undertaken by gas chromatography. Also some lipids health indices and lipids metabolism enzymes were determined. The studied lambs were males aged of 11–12 months of breeds and biotypes Highlander® (H), Merino Dohne (MD), Corriedale (C), Corriedale Pro® (CPRO), a crossing between Corriedale × Australian Merino (C×AM) and Romney Marsh (RM). The animals were reared on pasture in identical conditions without supplementation. The grazing was rotational based on a winter annual crops oats (Avena sativa spp.), cocksfoot, (Dactylis glomerata spp.) and white clover (Trifolium repens spp.). The results of the study did not show substantial differences between breeds regarding the fatty acids composition of meat, except for few relevant fatty acids such as C16:0 (MD>C), C18:3n3 (HCPRO, CxAM), C18:2n6 (H
