Abstract:
The aim of study was to determine the changes of frozen stored of Longissimus dorsi and Semimembranosus muscles and perirenal adipose tissue from Bulgarian Dairy Synthetic population lambs, fed a diet supplemented by 7.5 mg dihydroquercetin (DQ) or 545 mg dry distilled rose petals (DDRP)/kg life weight/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 + the addition of phytonutrients). Samples were collected 1 d post mortem. A half of them were analyzed immediately. Another half was vacuum-packed, quickly frozen at -40°C and stored for 365 d at -18°C. Supplementing of the lamb’s diet with polyphenol-rich phytonutrients reduces with 6.9 -12.9% the aerobic plate count, 9.3 - 25.3% the α-aminoacidic nitrogen, 31.8 - 45.9% the protein carbonyls and 38.9 - 63.4% TBARS (p ≤ 0.05) more pronounced in the m. Longissimus dorsi from lambs fed with 545 mg DDRP/kg/d. Further studies are needed to understand whether the use of higher doses of DDRP or DQ as supplements in the small ruminant’s diet will be able to provide a more pronounced inhibitory effect on oxidation processes in frozen lamb.
