| Experiments in laboratory silos (3 levels of molasses x 3 levels of N as ammonia or urea, or half N as urea and half as ammonia) showed that silages of good quality could be made from sugarcane tops alone or with the addition of molasses, urea or ammonia. Sugarcane tops ensiled alone had a low pH (3.8)) and a volatile fatty acid and lactic acid content similar to that reported in silages made from grass, whole crop maize and sunflower. Molasses lowered the pH and increased acetic and lactic acids levels but decreased propionic and butyric acids levels. When no N was added to the molasses, acetic acid production exceeded that of lactic acid but when N as ammonia was also added, lactic acid was the main acid formed. In presence of urea N, high levels of molasses were required to increase lactic acid levels. N as urea increased the pH and volatile fatty acid levels and severely depressed lactic acid formation. With ammonia N, these effects were less severe. The highest levels of ethyl alcohol (>2 per cent of dry matter silage) were obtained in the urea treatments, whether with or without molasses and the lowest levels were obtained in the ammonia treatments. The most suitable combination was molasses either at 5 or 10 per cent fresh weight cane tops and ammonia at 0.2 per cent N. | |
