Abstract

The inclusion of Dandelion meal [DL] (Taraxacum officinale) in the diet of laying hens and its effect on productive performance, intestinal morphology and dry matter content in feces was evaluated. Ninety-six 35-week-old brown Hisex hens were distributed in 6 treatments. Gradual levels of DM meal (1%, 2%, 3% and 4%) were compared with a diet based on the mixture of antibiotics (CAB; 0.03% Zinc bacitracin + 0.03% colistin sulfate) and another based of 0.20% sodium butyrate (CPB). DM and CPB improved egg production (p < 0.05) compared to CAB, but feed consumption and egg weight decreased with the use of 4% DM (p < 0.05), without affecting the feed conversion ratio (p > 0.05). In general, DM (1% 4%) improved intestinal morphology parameters (p < 0.05). Higher quantity and content of dry matter in feces was observed in 4% DM compared to CAB. The incorporation of up to 3% DM improved the productive indexes on the feeding of laying hens and managed to have the best prebiotic effect, as it was evidenced in the intestinal morphology and goblet cells.

以蒲公英（蒲公英）为基础的益生元饮食可改善蛋鸡的生产性能和肠道形态

评价了蒲公英粉在蛋鸡日粮中的添加及其对生产性能、肠道形态和粪便干物质含量的影响。96只35周龄的棕色海思母鸡被分为6个处理。将DM餐的逐渐水平（1%、2%、3%和4%）与基于抗生素混合物（CAB；0.03%杆菌肽锌+0.03%硫酸粘菌素）和另一种基于0.20%丁酸钠（CPB）的饮食进行比较。与CAB相比，DM和CPB提高了产蛋量（p<0.05），但在不影响饲料转化率（p>0.05）的情况下，使用4%DM可降低饲料消耗和蛋重（p<0.05）。总的来说，DM（1%4%）改善了肠道形态参数（p<0.05）；与CAB相比4%DM可观察到粪便中干物质的量和含量更高。添加高达3%的DM改善了蛋鸡饲养的生产指标，并取得了最佳的益生元效果，这在肠道形态和杯状细胞中得到了证明。
