| 摘 要： | 为了改善木薯叶青贮品质,研究有机酸对木薯叶青贮品质及营养成分的影响,以确定青贮木薯叶最适合的有机酸种类及添加量。本研究以华南7号木薯幼嫩茎叶为原料进行青贮试验,设对照组、甲酸（0.2%）、乙酸（0.2%）和丙酸（0.2%）处理组,30 d后测定木薯叶青贮饲料pH、乳酸（LA）、乙酸（AA）、丙酸（PA）和丁酸（BA）含量以及主要营养成分含量。结果表明,木薯叶直接青贮品质较差,添加有机酸处理与对照相比显著降低青贮饲料的pH和丁酸含量（P<0.05）,降低中性洗涤纤维（NDF）和酸性洗涤纤维（ADF）含量（P<0.05）,提高了饲料相对值（RFV）。添加有机酸可以改善木薯叶青贮品质并提高营养价值,添加乙酸（0.2%）和丙酸（0.2%）青贮品质较好,可作为木薯叶青贮添加剂。

| Abstract: | The experiment was carried out to investigate the influence of adding organic acids on the fermentation quality and nutrient contents of cassava foliage silage, and to determine the proper organic acids. Formic acid (0.2%), acetic acid (0.2%) and propionic acid (0.2%) were added in the study. All treatments were stored for 30 days, and the pH value, lactic acid, acetic acid, propionic acid and butyric acid content, and the nutrient composition of the cassava foliage silage were analyzed. The results showed that pH and the contents of butyric acid, the fiber content decreased in the organic acids treatments, while the RFV increased compared with the control (P<0.05). It is concluded that the organic acids treatment improved the fermentation quality and nutrient value of cassava foliage silage, acetic acid (0.2%) and propionic acid (0.2%) were the proper application. |
