Effect of Dietary Salicin Standardized Extract from Salix alba Bark on Oxidative Stress Biomarkers and Intestinal Microflora of Broiler Chickens Exposed to Heat Stress

The implication of heat stress (HS) in the oxidative phenomenon and its related diseases chickens has been widely reported. Salicin is a precursor for synthesis salicylic acid aspirin obtained from bark Salix alba, with an undeniable anti-inflammatory effect. However, little attention paid to salicin’s antioxidant/oxidative stress-reducing effect compared well-known purpose study was investigate dietary salicin standardized extract alba (SAB) on biomarkers intestinal microflora broiler exposed stress. In our study, (14 days) were randomly allocated three treatment groups (SAB0; SAB25; SAB50), each which included five replicates eight birds per replicate. Broilers (32 ± 2 °C) between 14 42 days. liver tissues collected analyze (total antioxidant capacity, glutathione, catalase, superoxide dismutase). content measurements microbial population performed (E. coli, staphylococci, lactobacilli). Results indicated that malondialdehyde protein carbonyls activity decreased (p < 0.05) SAB50 concomitantly linearly increased total glutathione concentration. Dietary supplementation SAB reduced abundance staphylococci number lactobacilli. Taken together, possesses advantageous status balance broilers These findings provide new insight into potential use damage prevention dysbiosis
