摘要
全株小麦在许多国家被用作主要的青贮饲料作物,小麦青贮是高产奶牛的优质粗饲料。小麦的营养组成随着成熟度的改变而改变,因此小麦的成熟度在一定程度上决定着小麦青贮的营养价值。此外,小麦的品种、施肥种类及用量、乳酸菌接种剂及青贮制作工艺均会影响小麦青贮的营养价值及发酵品质。本文简述了小麦青贮的营养价值、影响其营养价值与发酵品质的因素,以及小麦青贮在奶牛生产中的应用,以期为小麦青贮的应用推广提供参考。
Whole wheat is used as the main silage crop in many countries and can be used as high quality roughage for high yield dairy cows.The nutritional composition of wheat is changed with maturity changed,so the maturity determines the nutritional value of wheat silage to a certain extent.In addition,wheat varieties,fertilizer types and dosage,lactobacillus inoculant and silage production technology all affect the nutritional value and fermentation quality of wheat silage.The nutritional value of wheat silage,the influencing factors of its nutritional value and fermentation quality,and the application of wheat silage in dairy cow production were described in this paper with the aim to providing reference for the application and popularization of wheat silage.
