摘要: 随着规模化、标准化养殖场的快速发展,青贮饲料的需求也相应增加。全株玉米是我国重要的青贮饲料原料。农业生产副产物因含有较为丰富的蛋白质、维生素和氨基酸等营养物质也具有较高的饲喂价值,但由于其水分含量通常较高、高温时易腐败等原因导致综合利用水平低。混合青贮可通过原料间成分的互补性以及微生物的互作效应实现青贮饲料营养品质的均衡与提升,从拓宽饲料来源渠道、缓解饲料紧缺和提高农副产品的附加值等角度来说,混合青贮十分必要。但是,不同类型的混贮原料对全株玉米粗蛋白质含量及发酵品质的改善效果并不一致。因此,本文综述了全株青贮玉米与豆科牧草、禾本科牧草以及农业副产物等混合青贮的国内外研究进展,分析不同混贮类型对青贮饲料发酵品质的影响,以明确不同混贮组合的适宜混贮比例及特点,为我国饲料资源的高效利用和青贮饲料品质提升提供理论依据。

Abstract: With the rapid development of large-scale and standardized farms, the demand for silage has increased accordingly. Whole corn is an important silage raw material in China. Agricultural production by-products also have high feeding value because they are rich in nutrients such as proteins, vitamins and amino acids, but the level of comprehensive utilization is low due to their usually high moisture content and they are easy to rot at high temperatures. Mixed silage can realize the balance and enhancement of silage nutrient quality through the complementarity of ingredients and microbial interactions, which makes mixed silage necessary from the perspectives of broadening feed source channels, alleviating feed scarcity and improving the added value of agricultural by-products, etc. However, different types of mixed silage have different nutrient values, thus the improvement effects of different types of mixed silage ingredients on the crude protein content and fermentation quality of whole-plant corn are not consistent. Therefore, this paper reviewed the domestic and international research progress of mixed silage of whole plant silage maize with leguminous forage, grass forage and agricultural by-products, analyzed the effect of different mixed silage types on silage fermentation quality, in order to clarify the appropriate mixed silage ratio and characteristics of different mixed silage combinations, and to provide theoretical basis for the efficient utilization of feed resources and silage quality improvement in China.

Key words: whole corn, silage, mixed ensiling, fermentation quality
