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.

Key words: cassava foliage, organic acids, fermentation quality, nutrient composition
