Abstract: The effects of variety and processing method on feeding values of corn(Zea mays L.) were studied.The corn varieties of Zhongyuandan32,Nongda86,Nongda95,Nongda108,and NongdaGaoyou115 were harvested at dough stage and then processed for 45 d as whole-crop silage,stover only silage,or stover stack,respectively.The analytic results of samples indicate that the pH of the whole-crop corn silage was significantly lower than that of stover silage(P<0.05),and the lactic acid content was significantly higher(except for Nongda 86)(P<0.05).The CP content of the whole-crop corn silage was significantly higher than that of stover silage(P<0.05),and the NDF and ADF contents were lower.This inferred that the fermentative quality and nutrient contents of whole-crop corn silage were better than those of stover silage.The CP content of stover stack varied among varieties,and the NDF and ADF contents of stover stack were higher than those of silages.This inferred the lower nutrient quality of stover stack.The CP content of whole-crop corn silage of Zhongyuandan32 were significantly higher than that of others(P<0.05),and the fiber content of which was moderate.In general,the whole-crop corn silage had better feeding values and the Zhongyuandan32 performed better than others.

摘要: 为探讨品种和调制方法对玉米(Zea mays L.)植株品质的影响,选用中原单32、农大86、农大95、农大108、农大高油115为研究对象,于蜡熟期取样进行全株青贮、去穗秸秆青贮、秸秆干燥堆放处理。经贮存45d后,取样分析表明,各品种全株玉米青贮饲料的pH显著低于去穗玉米秸秆青贮饲料(P<0.05),而相应乳酸含量则显著较高(除品种农大86以外)(P<0.05),全株玉米青贮饲料的CP含量显著高于去穗玉米秸秆青贮饲料(P<0.05),NDF和ADF含量则相应较低,表明全株玉米青贮饲料的发酵品质和营养价值优于去穗玉米秸秆青贮饲料;干燥堆放玉米秸秆的CP含量因品种而有差异,其NDF和ADF含量都高于相应青贮饲料,表明干燥堆放秸秆的营养价值较低。中原单32全株玉米青贮饲料的CP含量显著高于其他品种(P<0.05),并且含有适度的NDF和ADF。总体而言,玉米植株以全株青贮为宜,而且全株青贮时,中原单32品质优于其它品种。
