Sarica, S.Erinc, H.Aydin, H.2024-11-072024-11-0720231792-2720https://doi.org/10.12681/jhvms.29193https://hdl.handle.net/11480/15709The present study compared the effects of the dietary supplementation of alpha-tocopherol acetate (TA) and pomegranate peel extract (PPE) alone or in combination in order to prevent oxidative stress created by the en-richment of the diet by 4 % flaxseed oil interms of the growth performance, and fatty acid composition, total phenolic contents, antioxidative profile and lipid oxidation of meat of broilers. A total of 600 day old Ross 308 male broiler chicks were randomly distributed into five treatments with 5 replicates of 24 chicks each.The diets included: CONT: a control diet containing 50 mg/kg TA and 4 % flaxseed oil; TA200: the diet supplemented with 200 mg/kg TA to the CONT diet; PPE100, PPE200 and TA100+PPE100: the diets supplemented with 100 and 200 mg/kg PPE and 100 mg/kg TA+100 mg/kg PPE to the CONT diet.The dietary treatments had no significant effect on growth performance. The TA200, PPE100, PPE200 and TA100+PPE100 diets significantly increased the contents of total polyunsaturated fatty acids (PUFAs), omega-6 fatty acids (FAs)and omega-3 FAs, total phenolic contents (TPCs), the 2,2-dipheny l-1-picry l hydrazy l radical scavenging activity and ferric reducing antioxidant power, and significantly decreased the concentrations of total saturated FAs, total monounsaturated FAs, the omega-6/omega-3 ratio and the malondialdehyde (MDA) values of the thigh meat and breast meat compared to the CONT diet. In conclusion, the PPE100, PPE200 and TA100+PPE100 diets were as effective as TA200 diet alone in terms of enriching broiler thigh meat and breast meat with the omega-3 PUFAs. The dietary combination of TA and PPE was a more effective antioxidant in terms of the lowest omega-6/omega-3 ratio of broiler breast meat, and the highest TPCs and the lowest MDA values of broiler thigh meat and breast meat enriched with omega-3 PUFAs compared to TA200 alone.eninfo:eu-repo/semantics/openAccessPomegranate peel extractmeatantioxidative potentiallipid oxidationbroilerArticle7415291530410.12681/jhvms.291932-s2.0-85153176306Q3WOS:000974582400025Q4
