Effects of dietary α-tocopherol acetate, pomegranate peel, and pomegranate peel extract on phenolic content, fatty acid composition, and meat quality of broiler chickens

Abstract

This study investigated the effect of dietary α-tocopherol (α-Toc), pomegranate peel extract (PPE), and pomegranate peel (PP) on phenolic content and breast meat quality of broilers during 11 days of storage with the addition of α-Toc, PPE, and PP. Broilers were fed eight dietary treatments, including: control diet, α-Toc diet (200 mg/kg), PPE diets (100, 200, and 300 mg/kg), and PP diets (1, 2, and 3 g/ kg) during 0-42 days. The extents of lipid oxidation in samples were assessed by measuring thiobarbituric acid-reactive substances and the 1, 1-Diphenyl-2-picrylhydrazyl radical-scavenging activities were determined. The feed efficiency was improved significantly in chickens fed diet containing 0.2 g/kg PPE, and the growth performance of chickens was impaired in chickens fed with PP diet. Long-chain polyunsaturated fatty acids n-3 were increased in breast muscles of broilers fed α-Toc and high levels of PPE diets (P < .05). Total phenolic contents and antioxidant activity in the breast meat were improved significantly when chickens fed diets containing α-Toc and PPE (P < .05). In conclusion, dietary supplementation with 200 and 300 mg/kg PPE may improve the antioxidant potential and quality indices of broilers breast meat. The antioxidant potential of PPE was equal to that of α-Toc in refrigerated meat.

Supplementation of Natural Antioxidants to Reduced Crude Protein Diets for Japanese Quails Exposed to Heat Stress

“…The lowest breast meat MDA values on day 0 were obtained when the RCP+TA200, RCP+PPE200 and RCP+APE200, and with the RCP+TA200 and RCP+PPE200 diets on day 7 of storage (p<0.05). These results are consistent with those of Habibian et al (2016), who showed that the dietary supplementation of vitamin E reduced the level of lipid oxidation (MDA value) of the breast meat of broilers under HS, and with those of Saleh et al (2015Saleh et al ( , 2017, who reported that dietary pomegranate peel extract significantly delayed the lipid oxidation of broiler meat. These findings may be attributed to polyphenolic compounds with the antioxidant activity present in PPE (Saleh et al, 2017), in addition to the synergism among phenolic compounds (Devatkal et al, 2010).…”

These polyphenolic compounds enter the circulatory system, distributed, and retained in breast meat of broilers, where they remain functional (Saleh et al, 2017).…”

Evaluation of Dietary Medicinal Plants and algae in Laying Japanese Quails

“…Therefore, they are considered as a promising dietary supplement, but data concerning their use in quail diets are limited (Abd El-Galil and Henda, 2015). Saleh et al (2017) showed that feeding pomegranate peel diet significantly improved the daily weight gain and decreased the feed to gain ratio of broiler chickens. The effects of medicinal plants on weekly egg production differ depending on the dietary medicinal plant type and dosage.…”

Performance of Hybrid Chickens as Influenced by Phytogenic Extracted Meal-Supplemented Diet as Antibiotic Alternatives During Summer

“…On the other hand, Bartov and Frigg (1992) who reported that BW gain was not significantly affected by dietary supplementation of vitamin E in broiler chicks. Moreover, chickens fed α-Toc-supplemented diet had no significantly enhanced growth performance contrasted with the control group (Saleh et al, 2017). Vasanthakumar et al (2013) founded that broiler fed supplementation of tulsi powder (0.5%) and commercial grade tulsi extract (0.1%) in the diet enhances the overall performance, antioxidant status and immunity in commercial broiler chickens during summer.…”

“…Addition their effect extensively scavenging effect on oxygen radicals in vivo and vitro because of their naturally flavonoids effects (Seyoum et al, 2006). Saleh et al (2017) who found that broiler fed pomegranate supplemented-diet, which contained natural antioxidant, had enhanced feed efficiency. The growth promoting effect of herbs was previously reported to enhance final body weight, WG and FCR of broiler chicks (Ibrahim et al, 1998).…”
