葡萄糖对王草青贮品质的影响
Effects of glucose addition on fermentation quality of imperatoria (Pennisetum purpureum Rich.×P.americana kinggrass cv) silages
摘要
Abstract
This study determined the best additive proportion of imperatoria glucose in order to provide technical reference for imperatoria silage quality improvement. [Method]In the process of imperatoria silage, 5, 10, 15, 20, and 25 g/kg of glucose were added to the imperatoria, then the fermentation quality and nutrient contents of the mixtures were evaluated and analyzed. [Result]The DM, CP, NDF, and ADF contents before and after imperatoria silage did not change significantly. The average color, smell, texture, and pH value indexes were evaluated as excellent grades. Compared to the tested results of the control group, although adding glucose did not show obviously notable effects in reducing the silage pH value, but this procedure could significantly enhance silage lactic acid content, which was at the total acid ratio of 69% and above. The Flieg's score was evaluated to an excellent grading (above 80 points). [Conclusion]Adding glucose to imperatoria could significantly improve the silage fermentation quality. The main nutrient content, however, did not change significantly. The imperatoria silage with 20 g/kg added glucose produced the best effects.关键词
