摘要: 试验旨在研究添加不同水平玉米粉对杞柳皮青贮品质的影响,探讨玉米粉最佳添加量。采用单因素完全随机分组设计,在杞柳皮中分别添加0%(对照组)、5%(Ⅰ组)、10%(Ⅱ组)和15%(Ⅲ组)玉米粉进行青贮,60 d后取样分析青贮常规营养成分和发酵品质,对青贮发酵品质进行综合评分。结果表明:随玉米粉添加量的增加,青贮料粗蛋白质(CP)含量先升高后降低,中性洗涤纤维(NDF)和酸性洗涤纤维(ADF)含量逐渐降低。对照组杞柳皮青贮料pH和NH3-N/TN最高,分别为4.76和11.09%,显著高于其他3组(P<0.05),分别高18.70%和98.75%、18.11%和96.63%、16.95%和85.76%,水溶性碳水化合物(WSC)含量分别低53.21%(P<0.05)、54.61%(P<0.05)、58.26%(P<0.05)。青贮饲料现场感官鉴定评分和发酵品质综合评价得分顺序均为试验Ⅰ组>试验Ⅱ组>试验Ⅲ组>对照组。在本试验条件下,根据现场感官鉴定以及综合评价青贮饲料发酵品质的各项指标,杞柳皮青贮以添加5%玉米粉效果最佳。

Abstract: The experiment was conducted to determine the effects of different corn meal addition levels on the silage quality of osier peel, and to discuss the appropriate level of corn meal addition.According to one-factor complete randomalized experimental design, there were 4 treatments groups which the corn meal addition levels were 0%(control group)、5%(group Ⅰ)、10%(group Ⅱ)and 15%(group Ⅲ), respectively.The general nutrient contents and fermentation quality were determined and the comprehensive scores of fermentation quality were evaluated after ensiling for 60 days.The results showed as follows:When corn meal addition amounts increased in osier peel silage, CP contents tended to raise, then dropped down, NDF and ADF contents declined gradually.Comparing with group Ⅰ、Ⅱ、Ⅲ, the pH and NH3-N/TN of silage in control group were the highest which were 4.76% and 11.09%, repectively, and that were increased by 18.70% and 98.75%、18.11% and 96.63%、16.95% and 85.76%, respectively, WSC contents was decreased by 53.21%(P<0.05)、54.61%(P<0.05)、58.26%(P<0.05), respectively.The score of both sensory evaluations and comprehensive assessments of fermentation quality were group Ⅰ>group Ⅱ>group Ⅲ>control group.According to the results obtained from sensory evaluations and comprehensive assessments of fermentation quality in this trial conditions, we concluded that the optimum supplement dosage of corn meal was 5% in osier peel silage.
