Due to the continuous increase in animal feed prices, and the presence of competition between humans and animals on food materials, it is imperative to identify other non-food plant resources to assist the animal feed industry and improve livestock productivity. Plant wastes may cause air, soil, and water pollution. However, if judiciously managed, they would be important resources. Plant wastes are used as feedstuffs and fertilizers. However, their use as animal feed is more useful than fertilizers. Because of the high content of fiber and non-protein N, these wastes are more valuable for feeding ruminants than poultry. The use of the plant wastes as feedstuffs could improve the environmental quality and profits for feed producers. Paulownias are fast-growing trees initially cultivated for wood production. However, due to their good nutritive value, their leaves have been used for ruminants, non-ruminants animals and poultry feeding. Furthermore, they are well-known for its medicinal and antibacterial properties. However, little is still known about its characteristics. This review aimed at providing detailed information about the nature, nutritional value, phytochemicals, and uses of Paulownia as a promising feedstuff in the fields of ruminants, non-ruminants, and poultry nutrition.

由于动物饲料价格的持续上涨，以及人与动物之间在食品原料上的竞争，必须找到其他非食品植物资源来辅助动物饲料行业并提高牲畜生产率。植物废料可能导致空气，土壤和水污染。但是，如果进行明智的管理，它们将是重要的资源。植物废料被用作饲料和肥料。然而，它们用作动物饲料比肥料更有用。由于纤维和非蛋白质N的含量很高，因此这些废料对反刍动物的饲养比家禽更有价值。将植物废料用作饲料可以改善饲料生产者的环境质量和利润。泡桐是最初种植用于木材生产的速生树木。然而，由于其良好的营养价值，它们的叶子已用于反刍动物，非反刍动物和家禽饲养。此外，它们以其药用和抗菌特性而闻名。但是，关于其特性仍然知之甚少。这篇综述旨在提供有关泡桐的性质，营养价值，植物化学物质以及将其用作反刍动物，非反刍动物和家禽营养领域有希望的饲料的详细信息。
