为了扩大西藏地区的饲料资源，以青稞秸秆和高羊茅为原料，分别添加0、10%、20%和30%的湿青稞酒糟（WHDG）进行混合青贮。青贮7、14、30 d后开仓，分析青贮料的发酵特性和营养品质。与对照相比，WHDG的添加显著提高了发酵品质，表现为pH下降速度加快，乳酸（LA）积累速度加快（p<0.05），丁酸含量和氨氮/总氮（p<0.05）降低。结果表明，添加WHDG不仅能有效抑制好氧菌的活性，而且能加快LA的产生，降低pH值，抑制有害菌的活性，使青贮料中残留的水溶性碳水化合物（WSC）增多。添加WHDG的青贮饲料蛋白质含量显著高于对照组（p<0.05）。总之，添加WHDG可提高秸秆青贮料的发酵性能和营养品质，且WHDG添加量大于20%时，这种效果更为显著。
In order to develop methods that would enlarge the feed resources in Tibet, mixtures of hulless-barley straw and tall fescue were ensiled with four levels (0, 10%, 20%, and 30% of fresh weight) of wet hulless-barley distillers’ grains (WHDG). The silos were opened after 7, 14 or 30 d of ensiling, and the fermentation characteristics and nutritive quality of the silages were analyzed. WHDG addition significantly improved fermentation quality, as indicated by the faster decline of pH, rapid accumulation of lactic acid (LA) (p<0.05), and lower butyric acid content and ammonia-N/total N (p<0.05) as compared with the control. These results indicated that WHDG additions not only effectively inhibited the activity of aerobic bacteria, but also resulted in faster and greatly enhanced LA production and pH value decline, which restricted activity of undesirable bacteria, resulting in more residual water soluble carbohydrates (WSC) in the silages. The protein content of WHDG-containing silages were significantly higher (p<0.05) higher than that of the control. In conclusion, the addition of WHDG increased the fermentation and nutritive quality of straw-grass silage, and this effect was more marked when the inclusion rate of WHDG was greater than 20%.
