Effects of selenium-enriched Bacillus sp. compounds on growth performance, antioxidant status, and lipid parameters breast meat quality of Chinese Huainan partridge chicks in winter cold stress

Abstract

BackgroundBoth selenium (Se) and probiotic Bacillus regulate the metabolism to help defense clod stress and improve the meat quality in breeding chicks. The purpose of this study was to evaluate the effect of supplemental Se and Bacillus in the form of Se-enriched Bacillus (SECB) on the growth performance, lipid parameters, breast Se and antibiotic levels, and breast meat quality of chicken in winter cold stress.MethodsFive hundred 1-d-old chickens were divided into five groups randomly: Control, inorganic Se, compound Bacillus, SECB, and antibiotic. The feed duration was 56 d.ResultsAfter 28 d of treatment, chicks feed SECB or compound Bacillus had higher body weights than the control, and after 56 d, chicks given either SECB or compound Bacillus had higher body weights than the control chicks or those given inorganic Se. Adding SECB to feed significantly increased the lightness, redness, and yellowness of breast meat, improved the water-holding capacity, and reduced the shear force and cooking loss. The concentration of Se in the breast muscle very significantly increased after SECB and inorganic Se supplementation, which was opposite to the concentration of flavomycin in antibiotic supplemented chicks. The antioxidative status of plasma and breast meat was significantly improved with added compound Bacillus and SECB: the total antioxidant capacity, total superoxide dismutase, and glutathione peroxidase ability in the breast muscle significantly improved, and the malondialdehyde concentration in plasma decreased. The levels of total cholesterol plasma triglyceride and very-low-density lipoprotein cholesterol in the plasma and breast muscle was decreased compared to that of the control, while the plasma high-density lipoprotein cholesterol concentration increased.ConclusionsIn conclusion, SECB supplementation promoted the body growth, antioxidative status, and Se concentrations in the plasma and breast meat, and also improved the breast meat quality.

Use of encapsulated Bacillus subtilis and essential oils to improve antioxidant and immune status of blood and production and hatching performance of laying hens

“…In the present study, BSEO exerted antioxidant activities by improving the activities of GSH-Px and T-AOC on serum. The results of the present study were in agreement with previous findings showed that dietary supplementation with BS or EO significantly increased activity of GSH-Px and T-AOC and gene expression (Bai et al 2017;Yu et al 2018;Yang et al 2019). Similarly, the addition of BS or EO had a positive response on antioxidant activity in serum of duck, goose, quail (Chen et al 2013;Attia et al 2017Attia et al , 2019Abdel-Moneim et al 2020).…”

Effects of selenide chitosan sulfate on glutathione system in hepatocytes and specific pathogen-free chickens

“…Compared with the control and CTS treatments, Se supplementation from different Se treatments (Na 2 SeO 3 , Se-CTS, and Se-CTS-S) indicated higher GSH-Px activity, GSH content, T-AOC, and mRNA levels of GPx-1 and GPx-4 in vitro and in vivo. These results further demonstrated that Se supplementation could improve the antioxidant function in vitro and in vivo ( Wu et al., 2010 , Fan et al., 2012 , Chen et al., 2017 , Yang et al., 2019 ). Moreover, the antioxidant activity of CTS was significantly higher following Se modification and Se-CTS was a more efficient compound ( Qin et al., 2015 ).…”

“…It is noteworthy that the antioxidant properties are one of the most important characteristics of Se compounds, especially regulating effects on antioxidant enzymes ( Khan et al., 2018 , Zoidis et al., 2018 , Yang et al., 2019 ). Compared with the control and CTS treatments, Se supplementation from different Se treatments (Na 2 SeO 3 , Se-CTS, and Se-CTS-S) indicated higher GSH-Px activity, GSH content, T-AOC, and mRNA levels of GPx-1 and GPx-4 in vitro and in vivo.…”

“…These results suggested that the biological ability of Se, especially the antioxidant activity, was more pronounced than that of sulfate. This could be explained by the theory that the antioxidant activities of sulfate and Se might be quite distinct as a result of utilizing different antioxidant mechanisms; sulfate itself does not primarily exhibit GSH-Px activity; moreover, as Se-dependent antioxidant enzymes, their expressions, activity, and effectors (GSH) of GPx were mainly regulated by Se rather than by sulfate ( Battin and Brumaghim, 2009 , Wu et al., 2010 , Chen et al., 2017 , Yang et al., 2019 ).…”

SEBS colonized in ileal mucosa, optimized bacterial composition, improved Se level and activated TLR2－NF-kB1 signaling pathway to regulate β-defensin 1 expression

“…The bacterial composition of the ileal mucous membrane and cecal lumen contents in all groups was determined using the plate method. Salmonella Shigella agar was used for salmonella and MRS agar was used for lactic acid bacteria [3,27]. The assays were repeated three times.…”
