The paper aimed to analyse the effect of dietary Salix alba L. bark powder (SAB) on broiler performance in terms of oxidative stress parameters in liver and gut microflora. One hundred and eighty Cobb 500 broiler chicks (14 days) were allotted to three homogeneous treatments (SAB 0%; SAB 0.025%; SAB 0.05%). The broilers were housed in an environmentally controlled space (10 replicates, six broilers/replicate). Compared to dietary control treatment (SAB 0%), the other treatments included 0.025% SAB (SAB 0.025%) and 0.05% SAB (SAB 0.05%). The results showed that SAB powder used in broiler diet had a high total phenolic content. Regarding the performance results, significant differences between experimental and control treatments were recorded only for average daily feed intake (35–42 days). The broilers fed with SAB powder had a significantly lower hepatic level of malondialdehide and glutathione, a higher total antioxidant capacity than those fed control treatment, and demonstrated a positive effect on the development of non-pathogenic bacteria (lactobacilli) but a decrease in the population of pathogenic ones (E. coli, staphylococci). Our findings suggested that dietary 0.05% SAB powder could be an effective solution to impede the oxidative stress in broiler liver and to improve gut microflora.

日粮白柳皮对肉仔鸡生产性能，氧化应激参数和肠道菌群的影响。

本文旨在分析日粮柳的功效。树皮粉（SAB）对肉鸡生产性能的影响（肝脏和肠道菌群中的氧化应激参数）。将180只Cobb 500肉鸡（14天）分配给三种均质处理（SAB 0％； SAB 0.025％； SAB 0.05％）。肉鸡被安置在环境受控的空间内（10个重复，六个肉鸡/重复）。与饮食控制治疗（SAB 0％）相比，其他治疗方法包括0.025％SAB（SAB 0.025％）和0.05％SAB（SAB 0.05％）。结果表明，用于肉鸡日粮中的SAB粉具有较高的总酚含量。关于性能结果，仅在平均每日采食量（35-42天）中记录了实验和对照处理之间的显着差异。饲喂SAB粉的肉鸡的肝中丙二醛和谷胱甘肽水平明显降低，乳酸杆菌），但致病菌（大肠杆菌，葡萄球菌）的数量有所减少。我们的研究结果表明，日粮0.05％的SAB粉可能是一种有效的解决方案，可以阻止肉鸡肝脏中的氧化应激并改善肠道菌群。
