Comparative analysis of various sources of selenium on the growth performance and antioxidant status in broilers under heat stress

Abstract

The supplementation of Selenium-enriched probiotics is effective in reducing oxidative stress and maintaining meat quality stability in broiler chicken especially under heat stress. An experimental study was conducted to perform Comparative analysis of Selenium yeast with inorganic Se in broilers under heat stress. A total of 120 broilers chicks of one day were assigned to 4 groups each consisting 30 chicks fed on same basal diet but different selenium sources. The basal diet of group D1 was not supplemented with Se source (Negative control), group D2 basal diet was supplemented with inorganic selenium (Sodium selenite 0.22mg/Kg starter phase and 0.15mg/Kg finisher phase), group D3 basal diet was supplemented with commercially available organic selenium (Seleno-methionine 0.22mg/Kg starter phase and 0.15mg/Kg finisher phase) and group D4 basal diet was supplemented with self-developed organic selenium (Se-enriched yeast 0.22mg/Kg starter phase and 0.15mg/Kg finisher phase). The performance parameters i.e. feed intake (FI), live body weight (BW) and FCR were not significantly (p>0.05) effected by selenium supplementation in the starter phase but were significantly (p<0.05) effected in the finisher phase. Selenium supplementation significantly (p<0.05) effected serum Se level in different supplemented groups. Higher serum Se value (58.20±0.06) was recorded in D4 group. Similarly significantly lower selenium value was recorded for D4 and higher was recorded for D1 (11.36±0.08). However lower serum Paraoxonase (PON) value was recorded for D4 (13.24±0.01) and higher for D1 (13.33±0.03). Comparatively self-developed Se enriched yeast increased the Se accumulation and improved antioxidant system. Glutathione peroxidase (GPx) was found higher in D4 (12.333±0.03) followed by D3, D2 and D1 respectively. Whereas superoxide dismutase (SOD) was significantly lower (p<0.05) in D4 (0.1437±0.003) followed by D3 (0.1457±0.002). Selenium supplementation increased the bird’s survival rate. Birds fed on Se enriched yeast showed higher Se deposition and better antioxidant capacity as compared to other sources of selenium. Se-enriched yeast displayed an improved result on Se deposition in tissues, and oxidative capacity, meat tenderness and immune response level as compared to other sources of selenium.

Effects of selenium supplementation on the growth performance, slaughter characteristics, and blood biochemistry of naked neck chicken

“…In the current investigation, the blood Se concentrations of the organically fed birds were higher than those of the control and inorganically fed birds. It is consistent with other observations that the blood Se concentration of the birds fed organic Se was higher ( Gul et al, 2021 ).…”

“…Furthermore, improved BWG, FI, and lower FCR due to the organic form of Se suggested that the body used it more effectively. These results support other researchers' assertions that the performance of the birds fed organic Se was superior ( Saleh and Ebeid, 2019 ; Gul et al, 2021 ). However, it was also discovered that supplementing broilers with Se had no effect on their ability to grow ( Chen et al, 2014 ; Li et al, 2018 ; Bakhshalinejad et al, 2019 ).…”

Effects of Tauroursodeoxycholic Acid and 4-Phenylbutyric Acid on Selenium Distribution in Mice Model with Type 1 Diabetes

“…In fact, the relationship between the two is particularly complex, so many studies have reached different views. Studies have shown that selenium can help prevent and treat diabetes via antioxidant and anti-oxidative stress effects [ 4 , 5 ]. However, the results of the National Health and Nutrition Examination Survey [ 6 ] and observational studies [ 3 – 7 ] indicate that serum selenium levels have positive correlations with the onset of diabetes mellitus.…”

Effect of Organic Selenium-Enriched Yeast on Relieving the Deterioration of Layer Performance, Immune Function, and Physiological Indicators Induced by Heat Stress

“…Some previous studies ( 67 – 69 ) and the present experiment showed that dietary Se supplementation could improve antioxidative status of chickens under heat stress condition. SY supplementation to HS-layer diets decreased the plasma MDA levels because SY can activate the biological activity of antioxidant enzymes, especially glutathione peroxidases, which, in turn, prevent the harmful effect of hydrogen peroxides and reduce the formation of reactive oxidative products ( 12 , 70 ). When layers were exposed to HS, SY supplementation reduced the levels of proinflammatory cytokines IL-1β and TNF-α through inhibiting the nuclear factor kappa-B (NF-κB) signaling pathway ( 71 ).…”
