摘要/Abstract

摘要： 本研究旨在评价添加不同水平青稞酒糟对箭筈豌豆与苇状羊茅（3∶7）混合青贮发酵品质的影响。试验设对照组(Control)和3个添加水平（10%、20%和30%）的青稞酒糟处理组，青贮后第7、14、30和60天后打开青贮窖，测定青贮饲料发酵品质。结果显示：添加青稞酒糟改善了混合青贮发酵品质，显著（P<0.05）提高了乳酸含量及乳酸/乙酸值，显著（P<0.05）降低了pH和氨态氮/总氮。添加青稞酒糟促进青贮早期乳酸发酵，使pH快速下降，有效抑制了青贮早期好氧性微生物的活性，进而降低了干物质和水溶性碳水化合物的损失。结果表明，添加10%青稞酒糟即可提高混合青贮发酵品质。

Abstract: This study was conducted to evaluate the effect of adding wet hullessbarley distillers- grains (WHDG) on the fermentation quality of mixed silage of common vetch and tall fescue during ensiling. Mixture of common vetch and tall fescue were ensiled by adding wet hullessbarley distillers'grains(WHDG), there were four adding levels (0, 10%, 20% and 30% of fresh weight). The silos were opened on 7, 14, 30 and 60 days after ensiling in triplicate and the fermentation quality was analyzed. The results showed that WHDG addition markedly improved the fermentation quality of mixed silage, which was well indicated by significantly (P<0.05) higher lactic acid content and lactic/acetic acid and significantly (P<0.05) lower pH and ammonia-N/total N in WHDG addition silages than these in control. WHDG addition greatly enhanced lactic acid production and pH decline during the early stage of ensiling, effectively inhibited the activity of aerobic bacteria, and resulting in lower loss of dry matter and water soluble carbohydrate. Based on the results, it can be concluded that the fermentation quality of mixed silage was considerably improved by 10% or more WHDG addition.
