摘　　要：为了评定山东省沿黄地区全株玉米青贮发酵品质和营养价值,以了解规模化牛场青贮玉米的制作现状,试验于2023年3—5月份分别采集沿黄地区滨州市、东营市、德州市、菏泽市、济宁市、济南市、聊城市、泰安市、淄博市的规模化奶牛场(51个)和肉牛场(54个)全株玉米青贮饲料样品共105份,测定样品的发酵品质和营养成分,参照《青贮玉米品质分级》(GB/T 25882—2010)对全株玉米青贮品质进行分级。结果表明:淄博市全株玉米青贮中乳酸含量显著高于其他市(P<0.05);德州市全株玉米青贮pH值显著高于滨州市、东营市、菏泽市、聊城市、泰安市和淄博市(P<0.05),其中淄博市全株玉米青贮pH值最低(3.15)。泰安市、滨州市全株玉米青贮淀粉含量较高,极显著高于东营市、德州市、菏泽市、济宁市、淄博市(P<0.01),聊城市极显著高于德州市、济宁市(P<0.01);济南市显著高于德州市、济宁市(P<0.05)。济南市全株玉米青贮中性洗涤纤维含量最高,极显著高于菏泽市、济宁市,滨州市、聊城市极显著高于济宁市(P<0.01)。德州市全株玉米青贮酸性洗涤木质素含量最高,极显著高于滨州市、东营市、聊城市、泰安市、淄博市(P<0.01),显著高于济南市(P<0.05);菏泽市、济宁市极显著高于淄博市(P<0.01)。德州市全株玉米青贮粗灰分含量最高,显著高于滨州市、东营市、聊城市、淄博市(P<0.05),菏泽市显著高于滨州市、聊城市、淄博市(P<0.05)。泰安市、济南市、滨州市、聊城市全株玉米青贮粗脂肪含量较高,极显著高于济宁市(P<0.01);东营市、德州市、淄博市显著高于济宁市(P<0.05)。各市间全株玉米青贮中乙酸、丙酸、酸性洗涤纤维、干物质、粗蛋白含量均差异不显著(P>0.05)。泰安市全株玉米青贮饲料品质为一级;济南市、聊城市、滨州市为二级;淄博市、济宁市、德州市、东营市和菏泽市为三级。To evaluate the fermentation quality and nutritive value of whole corn silage along the Yellow River in Shandong Province,and to understand the production status of corn silage in large-scale cattle farms,a total of 105 whole corn silage samples were collected from 51 large-scale dairy farms and 54 beef cattle farms of Binzhou City,Dongying City,Dezhou City,Heze City,Ji'ning City,Ji'nan City,Liaocheng City,Tian City,Zibo City along the Yellow River from March to May 2023,and the fermentation quality and nutrient composition of the samples were determined.Whole corn silage quality was graded according to Silage Corn Grading and Indexes(GB/T 25882—2010).The results showed that the lactic acid content of whole corn silage in Zibo City was significantly higher than that in other cities(P<0.05);the pH value of whole corn silage in Dezhou City was significantly higher than that in Binzhou City,Dongying City,Heze City,Liaocheng City,Tai'an City and Zibo City(P<0.05),and the pH value of whole corn silage in Zibo City was the lowest(3.15).The starch content of whole corn silage in Tai'an City and Binzhou City were significantly higher than that in Dongying City,Dezhou City,Heze City,Ji'ning City,and Zibo City(P<0.01);the starch content in Liaocheng was significantly higher than that in Dezhou City and Ji'ning City(P<0.01),and that in Ji'nan City was significantly higher than that in Dezhou City and Ji'ning City(P<0.05).The neutral detergent fiber content of whole corn silage in Ji'nan City was the highest,which was significantly higher than that in Heze City and Ji'ning City;the neutral detergent fiber content in Binzhou City and Liaocheng City was significantly higher than that in Ji'ning City(P<0.01).The acid detergent lignin(ADL)content of whole corn silage in Dezhou City was the highest,which was significantly higher than that in Binzhou City,Dongying City,Liaocheng City,Tai'an City and Zibo City(P<0.01),and significantly higher than that in Ji'nan City(P<0.05).The ADL content in Heze City and Ji'ning City were sign
