摘要/Abstract

摘要： 玉米因其高产量、高干物质、高纤维、高淀粉、高代谢能和适宜青贮的特点，近年来在其适栽区域作为发展草食畜牧业的青贮饲料愈发受到重视。玉米秸秆富含纤维，籽粒富含淀粉，高纤维和高能量兼具的营养特性让全株玉米成为从谷物密集要肉奶逐步转向饲草密集要肉奶的首选栽培饲用作物。同时，其植株各部位可分别青贮的特性使得玉米青贮独树一帜。本文基于秸秆青贮、果穗青贮、高湿玉米青贮、籽粒复水青贮、全株玉米青贮的近期研究进展，论述玉米不同部位的青贮特征和应用场景，并总结玉米纤维与淀粉消化率的主要影响因素及其提升策略，进而展望中国玉米青贮的未来发展方向。

关键词: 玉米青贮, 秸秆青贮, 果穗青贮, 高湿玉米, 籽粒复水青贮, 纤维消化率, 淀粉消化率

Abstract: In recent times,more attention has been paid to the production of corn silage for the development of herbivorous animal husbandry in corn suitable planting areas,owing to its high yield,high dry matter,high fiber,high starch,high metabolizable energy and the ability to make high-quality silage. Corn stalks and seeds are rich in fiber and starch,respectively. Whole-plant corn,which is high both in fiber and energy,will be a preferred cultivated forage crop for the gradual shift from grain-based feeding systems to forage-based feeding systems in China. At the same time,the fact that the different plant parts of corn can be ensilaged separately makes it unique. In this paper,we focused on silage characteristics and their application scenarios for different plant parts of maize based on the recent research developments in stalklage,earlage,high-moisture corn silage,rehydrated corn grain silage,and whole-plant corn silage. Current research progress on the factors affecting the digestibility of fiber and starch in corn silage and strategies to enhance their digestibility were also reviewed,and the future development of corn silage in China was discussed.

Key words: Corn silage, Stalklage, Earlage, High-moisture corn, Rehydrated corn grain silage, Fiber digestibility, Starch digestibility
