This study was conducted to evaluate the physical characteristics of the biomass crop Erianthus arundinaceus as a bedding material for broiler and to compare it with existing bedding materials. Three physical characteristics were evaluated: the water absorbability, the water-holding capacity, and the cushioning property. E. arundinaceus, shredded to five different particle sizes, was compared with sawdust, which is a typical bedding material used worldwide, and three alternatives: recycled paper, rice husks, and bagasse. E. arundinaceus absorbed water 5.0 to 10.2 times its weight, and water absorbability increased with decreasing particle size. E. arundinaceus held water around twice its weight regardless of the particle size. The cushioning property of E. arundinaceus tended to improve with increasing particle size. For each physical property, the total average value of the E. arundinaceus samples was compared with the values of other bedding materials. The water absorbability of E. arundinaceus was significantly higher than that of sawdust, recycled paper, and rice husks (p < .01). The water-holding capacity of E. arundinaceus was significantly higher than those of sawdust, recycled paper, rice husks (p < .01), and bagasse (p < .05). The cushioning property of E. arundinaceus was significantly higher than those of sawdust and recycled paper (p < .01). When E. arundinaceus had an average particle size of less than 2.33 mm, it exceeded sawdust in all physical characteristics, suggesting that E. arundinaceus could replace sawdust as a favored bedding material. Our observations of surface structures revealed that the stem pith of E. arundinaceus has a spongy structure, which may contribute to its high water absorbability and water-holding capacity. Moreover, the outermost layer of the E. arundinaceus stem appears to function like a leaf spring, contributing to the high cushioning property.

作为肉鸡垫料的花莲的物理特性

本研究旨在评估生物质作物Erianthus arundinaceus作为肉鸡垫料的物理特性，并将其与现有垫料进行比较。评价了三个物理特性：吸水性、保水性和缓冲性。E。 _ 将切碎成五种不同颗粒大小的arundinaceus与锯末（一种全球使用的典型垫料材料）和三种替代品进行了比较：再生纸、稻壳和甘蔗渣。E。 _ arundinaceus吸水量是其重量的 5.0 到 10.2 倍，吸水性随着粒径的减小而增加。E。 _ 砗磲无论颗粒大小如何，都能将水保持在其重量的两倍左右。E的缓冲性能。 arundinaceus倾向于随着粒径的增加而改善。对于每个物理性质， E的总平均值。 arundinaceus样品与其他垫料的值进行了比较。E的 吸水性 arundinaceus的含量显着高于锯末、再生纸和稻壳 ( p  < .01)。E的持水能力。 arundinaceus的含量显着高于锯末、再生纸、稻壳 ( p  < .01) 和甘蔗渣 (p  < .05)。E的缓冲性能。 arundinaceus显着高于锯末和再生纸 ( p  < .01)。当E . arundinaceus的平均粒径小于 2.33 mm，在所有物理特性上都超过了锯末，这表明E . arundinaceus可以代替锯末成为受欢迎的垫料材料。我们对表面结构的观察表明E的茎髓。 arundinaceus具有海绵状结构，这可能有助于其高吸水性和保水性。此外， E的最外层。 arundinaceus茎似乎起到板簧的作用，有助于提高缓冲性能。
