1. This study investigated the effects of daily intake of silage or haylage on broiler production performance and organ development. Furthermore, effects of daily intake of Lactobacillus plantarum either via silage or by supplemented drinking water, on Campylobacter jejuni loads in faeces were studied.

2. To test this, a 42-d experiment using Ross 308 and a 63-d experiment with Rowan Rangers hybrids, were performed. Silage inoculated with L. plantarum strain 256 and haylage were fed in total mixed rations with mixtures of 85% of pellets and 15% of respective forage (DM-based weight). Feed intake (FI), forage intake, body weight (BW) and feed conversion ration (FCR) were monitored weekly. Mortality was recorded daily, and organ weights were registered at slaughter. Quantification of C. jejuni was performed by colony counts from faecal samples after culture on agar plates.

3. There was a negative effect of haylage on BW and FI in the fast-growing Ross 308 hybrid. Silage had a negative effect on BW only on week four and six. Water inoculated with L. plantarum 256 increased BW in the starter period. Interestingly, no significant adverse effect of forage inclusion was observed in the Rowan Ranger birds.

4. Relative weight of the emptied gizzard was higher in both Ross 308 and Rowan Ranger birds fed haylage and silage than in the control group. In Ross 308 birds, both forages significantly reased the relative weight of gizzard with digestive content when compared to birds fed solely pellets.

5. In both studies, higher consumption of silage than haylage was observed.

6. In conclusion, daily intake of L. plantarum 256 either via silage or supplemented in drinking water, was not effective in reducing the shedding of C. jejuni in either Ross 308 or Rowan Ranger hybrids at the end of the rearing period.

1.这项研究调查了每天摄入青贮饲料或青贮饲料对肉鸡生产性能和器官发育的影响。此外，每天摄入的影响植物乳杆菌要么通过青贮或辅以饮用水，对空肠弯曲菌进行了研究粪便负荷。

2.为了对此进行测试，进行了使用Ross 308的42天实验和使用Rowan Rangers杂种的63天实验。接种了植物乳杆菌256和青贮饲料的青贮饲料，其总混合日粮中混合了85％的小球和15％的相应草料（基于DM的重量）。每周监测饲料摄入量（FI），饲料摄入量，体重（BW）和饲料转化率（FCR）。每天记录死亡率，屠宰时记录器官重量。在琼脂平板上培养后，通过粪便样品的菌落计数对空肠弯曲杆菌进行定量。

3.快速增长的Ross 308杂种中，Haylage对BW和FI有负面影响。青贮饲料仅在第4和第6周对BW产生负面影响。接种植物乳杆菌256的水在启动期增加了体重。有趣的是，在Rowan Ranger鸟类中未观察到明显的草料包涵不良影响。

4.饲喂了青贮饲料和青贮饲料的Ross 308和Rowan Ranger禽的空izz的相对重量均高于对照组。与仅饲喂颗粒饲料的鸟类相比，在罗斯308鸟类中，两种饲料均显着降低了具有消化成分的izz的相对重量。

5.在两项研究中，均观察到青贮饲料比青贮饲料消耗更高。

6.总之，在饲养期末，每天通过青贮饲料或补充饮用水摄入植物乳杆菌256不能有效减少Ross 308或Rowan Ranger杂种中空肠弯曲杆菌的脱落。
