Plant composition as well as preparation method and application thereof

The invention discloses a plant composition as well as a preparation method and application thereof, and relates to the technical field of feeds. The invention provides a plant composition. The plant composition is prepared from the following components: carnosic acid, carnosol and vitamin D, the weight ratio of the carnosic acid to the carnosol to the vitamin D is (1-5): (2-4): (1-5). Research on compounding of active components of rosemary finds that when carnosic acid, carnosol and vitamin D act together to form a plant composition to be applied to feed, the growth performance and slaughter performance are greatly improved. The inventor of the application also finds that compounding of rosemary essential oil, carnosic acid, carnosol and vitamin D can further improve the performance. 本发明公开一种植物组合物及其制备方法与应用，涉及饲料技术领域。本发明提供了一种植物组合物，包括以下组分：鼠尾草酸、鼠尾草酚、维生素D；所述鼠尾草酸、鼠尾草酚、维生素D的重量比为：鼠尾草酸：鼠尾草酚：维生素D＝1-5:2-4:1-5。本发明通过对迷迭香活性组分的复配研究发现，鼠尾草酸、鼠尾草酚、维生素D共同作用，形成植物组合物应用于饲料中时，生长性能及屠宰性能大大提高。本申请发明人还发现，迷迭香精油和鼠尾草酸、鼠尾草酚、维生素D的复配可以进一步提升上述
