Résumé
Forty male lambs Manchego breed were used. The basal diet was formulated to be rich in omega-3 fatty acids, with extruded linseed (6%) and fish oil (1%). The lambs were randomly distributed in five experimental groups: 300 ppm of vitamin E (-tocopherol acetate) (GVE), two groups with olive extract rich in hydroxytyrosol dose of 1500 ppm (G1500) and 3000 ppm (G3000), a group with 300 ppm of vitamin E and 1500 ppm of olive extract (GMIX) and a control group (CG).The TBARs values increased from 0 to 12 days in GC, G1500 and G3000. The metmyoglobin proportion increased during storage, being equal for all groups the first 6 days. In G1500, G3000 and GC, a significant increment in metmyoglobin proportion between 6 to 12 days of storage WAS been observed. The value of a* increased from day 0 to 6 of storage in GC, G1500, G3000 and GMIX whereas decrease at 12 day of storage except in GMIX which was similar to 6 day value. GVE the value of a* was constant along storage. The value of h* increased from 6 to 12 day for GC and G1500 and it was relatively constant along storage in G3000, GMIX and GVE.
