Abstract

This study was aimed to evaluate the effect of sugarcane molasses on the silage quality of sorghum-sudangrass hybrid (Sorghum bicolor × Sorghum sudanense). To explore this objective Sorghum-sudangrass hybrid was harvested at the milking stage and well-chopped for making silage in the laboratory silos by using sugarcane molasses at the rate of 0, 1, 2, and 3%. Silage developed so, was analyzed for nutritive quality traits (dry matter, pH, crude protein, neutral detergent fiber, acid detergent fiber, cellulose, hemicelluloses and ash). Silage quality was also assessed by calculating digestible dry matter, dry matter intake, digestible energy, metabolizable energy and relative feed value. Flieg score was deliberated by using the pH and dry matter. The results of the research revealed that application of molasses improved dry matter (26.27%), crude protein (8.14) and ash contents (7.68) as compared to the control, but had lower values of pH (3.99), neutral detergent fiber (57.86), acid detergent fiber (30.74), lignin (3.72), cellulose (27.02) and hemicelluloses (27.13) in comparison with the untreated silage (control). Flieg score of treated silage was also in the category of very good. All these findings lead us to conclude that the silage quality of sorghum-sudangrass can be considerably improved by the use of sugarcane molasses as an additive. Molasses addition at a rate of 3% can improve the nutritive value of sorghum-sudangrass silage to the maximum extent.

添加甘蔗糖蜜可以提高高粱-苏丹草杂交品种的青贮品质
本研究旨在评价甘蔗糖蜜对高粱-苏丹草杂交种(双色高粱×苏丹高粱)青贮品质的影响。为了探索这一目标,在挤奶阶段收获高粱-苏丹草杂交种,并在实验室筒仓中用0、1、2和3%的甘蔗糖蜜充分切碎制成青贮饲料。分析了开发的青贮饲料的营养品质特征(干物质、pH值、粗蛋白、中性洗涤纤维、酸性洗涤纤维、纤维素、半纤维素和灰分)。通过计算可消化干物质、干物质摄入量、可消化能量、代谢能量和相对饲料价值来评估青贮饲料的质量。Flieg评分是通过使用pH值和干物质来考虑的。研究结果表明,与对照相比,施用糖蜜提高了干物质(26.27%)、粗蛋白质(8.14)和灰分(7.68),但与未处理的青贮饲料(对照)相比,pH值(3.99)、中性洗涤纤维(57.86)、酸性洗涤纤维(30.74)、木质素(3.72)、纤维素(27.02)和半纤维素(27.13)较低。经过处理的青贮饲料的Flieg评分也属于非常好的类别。所有这些发现使我们得出结论,使用甘蔗糖蜜作为添加剂可以显著提高高粱苏丹草的青贮品质。添加3%的糖蜜可以最大限度地提高高粱苏丹草青贮饲料的营养价值。
