Creeping Wood Sorrel and Chromium Picolinate Effect on the Nutritional Composition and Lipid Oxidative Stability of Broiler Meat

Abstract

The study investigates the efficacy of Cr in broilers, aiming to evaluate the effects of Chromium picolinate (CrPic) in association with creeping wood sorrel powder (CWS) on the proximate composition, fatty acids profile, bioactive nutrients and lipid oxidative stability of broiler meat. A total of 120 Cobb 500 chickens were assigned into three treatments: a control diet (C) and two test diets, including 200 µg/kg diet CrPic (E1), and 200 µg/kg diet CrPic +10 g CWS/kg diet (E2). Dietary supplementation with Cr + CWS significantly improved the concentration of n − 3 polyunsaturated fatty acids (PUFAs), while its n − 6/n − 3 ratio decreased in comparison to the group receiving Cr and the conventional diet. The concentration of docosahexaenoic acid (DHA) significantly increased in the breast meat collected from the E2 group than that from the C group. Dietary administration of Cr and CWS improved lutein and zeaxanthin content, decreased Fe and Zn levels of the breast, and increased Zn deposition in the thigh samples. Malondialdehyde (MDA) concentration decreased more in the thigh meat of the supplemental groups (E1, E2) than in that from the C group. In conclusion, the current study suggests that Cr together with CWS can be a viable option as antioxidant sources for broiler diets, promoting the nutritional quality of meat.

Effects of Supplementing Sea Buckthorn Leaves (Hippophae rhamnoides L.) and Chromium (III) in Broiler Diet on the Nutritional Quality and Lipid Oxidative Stability of Meat

“…Nevertheless, vitamin E was poorly deposited in the breast and thigh meat of chickens fed T1 and T2 treatments compared to T0. Similar results were reported by [ 25 ] when Cr was supplemented in combination with creeping wood sorrel in chicken diets. However, other authors [ 68 ] showed that the vitamin E content of sea buckthorn fruit oil had no significant effect on the depostion in rat livers and attributed this effect to the high individual variability of the biological response between the animals used.…”

“…The fatty acid profile obtained from the chemical analysis (as g/100 g fatty acid methyl esters) was used to determine several nutritional quality indices of meat lipids. Nutritional quality indices of meat lipids were assessed by calculating the PUFA n-6/PUFA n-3, Σ PUFA/Σ MUFA ratio, atherogenicity index (IA), thrombogenicity index (IT), saturation index (SI), the ratio of hypocholesterolemic and hypercholesteremic fatty acids (h/H), and the health-promoting index (HPI) as previously described [ 25 ].…”

“…The total phenol content (TPC) was measured spectrophotometrically according to the Folin–Ciocalteu’s method from the extracts obtained previously in methanol 80% p.a., (1:10, w / v ) for SBL samples and in a solution of phosphate-buffered saline (PBS) at pH 7.4 (1:10, w / v ) for meat samples according to the method described previously [ 25 ]. Absorbances were recorded at 732 nm against a blank solution and the concentrations (as mg gallic acid equivalent (GAE)/g) were calculated using gallic acid as the standard solution.…”

Effect of dietary supplementation of some antioxidant combinations on nutrient digestibility in heat-stressed broilers

“…The lutein and zeaxanthin content in liver was significantly lower in the experimental groups compared to C group. In contrast, the results of a previous study (Saracila et al, 2022) performed under normal temperature showed an increased content of lutein and zeaxanthin in breast and thigh samples from chickens fed a diet supplemented with Cr and CWS. However, the total antioxidant capacity recorded in the liver was significantly higher in group Cr-VC, Cr-Zn and Cr-CWS compared to C. These observations indicate that vitamin C and Zn supplementation have led to increased antioxidant capacity in the liver.…”

“…The creeping wood sorrel plants were harvested from Ilfov county in their late vegetative stage, slow dried and grounded. Plant samples were characterized previously by Saracila et al, (2022) that revealed important concentration of crude protein (16.74%), crude fibre (19.36%) and ash (22.56%), high concentration of lutein and zeaxanthin (267.41µg/g) and vitamin E (210.93µg/g) with a high total antioxidant capacity (170.70 µM Trolox).…”
