Table 2. Effect of Se-enriched probiotics on selenium (Se) tissue deposition, activities of GSH-Px and SOD and levels of GSH and MDA in the liver under heat stress conditions.
| Parameters | Treatments | |||
|---|---|---|---|---|
| Con | P | SS | SP | |
| Se liver deposition (ng/g) | 351.1 ± 23.6c | 371.4 ± 19.6c | 574.3 ± 7.1b | 700.5 ± 6.3a |
| GSH (mg/g) | 4.55 ± 0.68c | 5.00 ± 0.29c | 10.81 ± 1.09b | 16.57 ± 1.14a |
| GSH-Px (u/mg) | 6.43 ± 0.40c | 6.15 ± 0.32c | 11.53 ± 0.68b | 19.29 ± 1.00a |
| SOD (u/mg) | 61.71 ± 3.90c | 87.85 ± 3.43b | 92.42 ± 3.28b | 132.60 ± 1.69a |
| MDA (nmol/mg) | 1.53 ± 0.09a | 0.388 ± 0.04b | 0.398 ± 0.04b | 0.094 ± 0.02c |
Effect of P, SS, and SP on selenium tissue deposition (ng/g), GSH level (mg/g protein), GSH-Px activity (u/mg protein), SOD activity (u/mg protein), and MDA levels (nmol/mg protein) of the liver in heat stressed broiler chickens, feeding of basal diet without Se (Con group), the basal diet with the addition of P group, the basal diet with the addition of SS group, and the basal diet with the addition of SP group. Mean values with their standard errors. The values with unlike superscript letters (a, b, c) in the graph were different (p < 0.05).
