Effect of synbiotic supplementation and dietary fat sources on broiler performance, serum lipids, muscle fatty acid profile and meat quality

Abstract

A 42-d trial was conducted to investigate the effect of adding a synbiotic supplement to diets containing two different types of fat on performance, blood lipids and fatty acid (FA) composition and oxidative stability of breast and thigh meat in broilers. A total of 800 one-d-old male broiler chickens were randomly assigned into 1 of 8 treatments with 4 replicates of 25 birds per treatment. The experiment consisted of a 4 × 2 factorial arrangement of treatments including 4 concentrations of synbiotic (0, 0.5, 1 or 1.5 g/kg diet) and 2 types of fat [sunflower oil (SO) or canola oil (CO)] at an inclusion rate of 50 g/kg diet. Dietary fat type did not affect body weight gain (BWG) or feed conversion ratio (FCR) during the overall experimental period (0-42 d). However, fat type modified serum lipid profile and FA composition and 2-thiobarbituric acid-reactive substances (TBARS) content in breast and thigh meat. The addition of synbiotic to the diet linearly improved overall BWG and FCR and also decreased serum cholesterol and low-density lipoprotein cholesterol concentrations. The TBARS value in thigh meat after 30 d of storage at 4°C was linearly decreased as the synbiotic inclusion concentrations in the diets increased. Dietary synbiotic also decreased the proportion of monounsaturated fatty acids and increased n-6 polyunsaturated fatty acid (PUFA) concentration in thigh meat, whereas the FA profile of breast meat was not affected by synbiotic supplementation. Moreover, the PUFA/SFA ratio in the breast meat was linearly increased when synbiotic was included in the CO-containing diets. In conclusion, the addition of synbiotic to broiler diets had a positive effect on growth performance, blood lipid profile and meat quality. The results also support the use of synbiotic to increase the capacity of canola oil for enhancing PUFA/SFA ratio of breast meat in broilers.

The Effect of Synbiotic Supplementation on Body Composition and Lipid Profile in Patients with NAFLD: A Randomized, Double Blind, Placebo-Controlled Clinical Trial Study

“…Findings of a recent metaanalysis indicated that probiotics had a significantly good effect on normalizing total cholesterol, as we observed (27). Ghasemi findings also indicated that the addition of synbiotic to the diet decreased serum cholesterol and LDL cholesterol concentrations in broilers (28). In contrast with our results, Wong VW et al did not find any significant effect for Lepicol probiotic and prebiotic formula on body mass index, waist circumference, glucose, and lipid levels (29).…”

“…Ghasemi et al . [45] observed a similar effect of improved FCE after administration of synbiotics in broiler chicken diets. In contrast, Murshed and Abudabos [46] reported poorer FCE in chickens fed diets with a synbiotic consisting of MOS, beta-glucans, and a highly active strain of Bacillus subtilis (DM17299).…”

“…Axling et al () also noticed that the supplementation of probiotic down‐regulates the mRNA expression of hepatic lipogenic enzyme in broilers, with a subsequent reduction in the liver lipogenesis. Conflicted with these findings, others reported that synbiotic supplements did not modify the serum triglyceride and VLDL levels (Ghasemi, Shivazad, Mirzapour‐Rezaei, & Karimi‐Torshizi, ). It is interesting to notice the decreased serum total protein and albumin in the OA‐supplemented group.…”

“…Additionally, Min, Yang, Xu, and Gao () reported that the broiler diets supplemented with a combination of B. subtilis and mannan‐Oligosaccharide reduced the plasma MDA level. The lowered MDA level may be related to the regulatory action of synbiotics on the FA profiles of broiler muscles (Ghasemi et al, ). Recently, Zhang et al () observed that the dietary supplementation of synbiotic decreased the 8‐OHdG level in broiler chicks at 21 day of feeding ( p < 0.05).…”
