这篇综述概述了有关油菜粉的已发表数据及其作为大豆粉替代植物来源蛋白质来源的鸭的适用性。油菜粗粉是一种豆类来源的蛋白质来源,含有与大豆粗粉相当的氨基酸谱,并富含必需的矿物质和维生素。尽管如此,已知它含有比豆粕更少的能量含量。像田间条件和加工方法这样的因素会在油菜粉之间产生成分差异。存在抗营养因子,如酚类物质,已知会降低家畜动物生长性能的植酸和芥子油苷,是油菜粉在饲料工业中成为有竞争力的植物来源蛋白质来源的主要缺点。这篇综述的重点是解决i)鸭的油菜粉的营养特性和饲喂价值,以及ii)饲喂油菜粉对鸭性能的影响。

review provides an overview of the published data on the canola meal and its suitability for duck as an alternative plant-origin protein source to soybean meal. Canola meal is a legume origin protein source containing comparable amino acid profile to soybean meal and rich in essential minerals and vitamins. Nonetheless, it is known to contain less in energy content than soybean meal. Factors like field conditions and processing methods creates compositional variations among canola meal. Presence of anti-nutritional factors such as phenolic substances, phytate and glucosinolates which are known to reduce growth performance in livestock animals, are the major drawbacks for canola meal to be a competitive plant-origin protein source in the feed industry. This
review is focused to address i) nutritional characteristics and feeding value of canola meal for ducks and ii) impacts of feeding canola meal on performances of ducks.
