Using invasive plants in animal production can provide an economical and eco-sustainable competitive advantage in a globalized market. The and the L. are invasive plants historically used by Azorean farmers as an alternative ruminant water source in the summer. This study aims to better understand their properties and how they vary throughout the year, so their use to complement animal diets can be optimised. Six samples of each species were collected on the Terceira Island during 2 growth seasons: winter (January 2021) and summer (September 2021), and their chemical composition, in vitro digestibility, and gas production, were determined. Significant ( < 0.05) differences were found in all parameters between the summer and the winter, with larger variations in both fibre (NDF and ADF) and digestibility parameters found between the and the . Gas production was greater in the summer for and in the winter for . Even though the digestibility was lower in the summer, we found that both plants offer a viable ruminant feed complement in both seasons, providing a cheap and eco-sustainable alternative water source, that can be associated to dry forage and compound feeding stuff with a high crude protein content when designing ruminant diets.
在动物生产中使用入侵植物可以在全球化市场中提供经济且生态可持续的竞争优势。[植物名称1]和[植物名称2] L.是入侵植物，亚速尔群岛的农民历史上在夏季将其用作反刍动物的替代水源。本研究旨在更好地了解它们的特性以及全年的变化情况，以便优化它们在动物日粮中的使用。在2个生长季节（冬季（2021年1月）和夏季（2021年9月））期间，在特塞拉岛采集了每个物种的6个样本，并测定了它们的化学成分、体外消化率和产气量。夏季和冬季之间在所有参数上均发现了显著（<0.05）差异，[植物名称1]和[植物名称2]之间在纤维（中性洗涤纤维和酸性洗涤纤维）和消化率参数方面的变化更大。[植物名称1]的产气量在夏季更高，[植物名称2]的产气量在冬季更高。尽管夏季的消化率较低，但我们发现这两种植物在两个季节都为反刍动物提供了可行的饲料补充，提供了一种廉价且生态可持续的替代水源，在设计反刍动物日粮时，可以与干饲料和高粗蛋白含量的复合饲料搭配使用。
