Abstract: Abstract The aim of the study was to determine the quality changes of frozen muscles of Longissimus dorsi and Semimembranosus and perirenal adipose tissue from lambs fed a diet supplemented by 7.5 mg dihydroquercetin/kg/d, or 545 mg dry distilled rose petals (DDRP)/kg/d. Three groups of 10 male lambs aged 65 days were fed 50 days ad libitum : a control (ground alfalfa + granular compound feed) and two experimental groups (the same diet but with the addition of phytonutrients). Samples were collected 1 d post mortem. A half of them were analyzed immediately and another one was vacuum-packed, frozen at -40°C and stored for 365 d at -18°C. It has been found that supplementing the lamb's diet with polyphenol-rich phytonutrients contributes to certain reduction in aerobic plate count, α-aminoacidic nitrogen, protein carbonyls, TBARS and the content of saturated fatty acids, but with small amplitudes, more pronounced in the m. Longissimus dorsi from lambs fed with 545 mg DDRP/kg/d. Further studies are needed to answer the question of whether the use of higher doses of DDRP or dihydroquercetin as supplements in the small ruminant's diet will be able to provide a more pronounced inhibitory effect on oxidation processes in frozen lamb.
