马铃薯淀粉渣混合青贮玉米快速饲料发酵方法研究

Study on Fast Fermentation Method of Potato Starch Slag Mixed Silage Corn Feed

马铃薯淀粉渣与青贮玉米按不同发酵方式和不同混合比例进行发酵,结果表明,采用厌氧发酵、马铃薯淀粉渣与青贮玉米混合比例为1∶2时,发酵产物颜色佳、酸度适宜、质地松软,且发酵速度快,效果好,营养较为丰富,其干物质、粗蛋白、粗纤维、粗脂肪、钙和磷含量分别达205.5 g/kg、60.1 g/kg、293.5 g/kg、25.3 g/kg、3.9 g/kg和2.5 g/kg。

The potato starch residue mixed silage corn is fermented,and the comparative test is carried out by setting different stacking ways and different mixing proportions. The result shows that using anaerobic fermentation processing method of potato residue mixed silage corn(1 ∶ 2),the fermented feed color is good,the acidity is suitable,the texture is soft,the fermentation speed is quick,the effect is good,and the nutrition is rich. The dry matter,crude protein,crude fat,crude fiber,calcium and phosphorus content are 205.5 g/kg,60.1 g/kg,293.5 g/kg,25.3 g/kg,3.9 g/kg and 2.5 g/kg,respectively.
