切碎长度对玉米青贮品质的影响研究

目的]利用全株玉米进行不同切碎长度青贮,探索适宜的切碎长度。方法]以贵州本地玉米品种为青贮原料,通过感观评定、化学评定以及相关营养指标分析研究不同切碎长度对玉米青贮品质的影响。结果]不同切碎长度对全株玉米青贮料品质有一定的影响。切碎长度较短的青贮饲料品质优于切碎长度较长的青贮料,其中1.5 cm组优于2 cm组和3 cm组。结论]该研究结果可用于指导奶牛生产。

Study on the Effects of Chopping Length on the Quality of Corn Silage

Objective] The research aimed to silage whole-plant corn with different chopping length and discuss the optimum chopping length.Method] Using Guizhou local corn variety as silage materials,the effects of different chopping length on the silage quality of corn were studied by sensory evaluation,chemical evaluation and the analysis of related nutritional indices.Result] Different chopping length had some influences on the silage quality of whole-plant corn.The silage quality with shorter chopping length was better than that with longer chopping length.And the silage quality in 1.5 cm group was better that in 2 cm group and 3 cm group.Conclusion] The research results could be used for guiding the production of cows.
