ABSTRACT

This study was proposed to examine the effects of pine needles powder (Pinus brutia) supplementation on growth performance, breast meat composition, and antioxidant status in broilers fed linseed oil-based diets. For this purpose, a total of 210, Ross-308 1-day-old male broiler chicks were allocated to 5 experimental groups each containing 42 birds. Broilers were fed a linseed oil-based basal diet supplemented with 0% (control), 0.25% (P1), 0.50% (P2), 0.75% (P3), and 1% (P4) pine needles powder. During the 42-D feeding period, no significant differences were observed between experimental groups for body weight gain, feed intake, and feed conversion ratio; however, carcass yield was increased linearly with pine needles powder supplementation. No marked changes in the breast meat chemical composition were observed among experimental groups. Supplemental pine needles powder linearly decreased the malondialdehyde concentration in breast meat and liver tissues; however, 2,2-diphenyl-1-picrylhydrazyl radical scavenging activity of breast meat samples remained unaffected. No significant variation was observed among experimental groups for superoxide dismutase enzyme activity in blood erythrocyte lysates, but blood serum total oxidation status tended to decrease with pine needles powder supplementation. In conclusion, results suggested that pine needles powder supplementation to broiler diets could be a viable option to improve the animal antioxidant status and meat oxidative stability; however, supplementation of Pinus brutia needles powder up to 1% into broiler diets was not sufficient to efficiently curb the fat-induced oxidation in meat. Further investigation is needed to determine the full antioxidant potential of pine needles powder supplementation in poultry by comparing different pine species, evaluating the bioavailability of their active compounds and determining most effective dietary concentration for broiler meat production without any adverse effects.
