- Abstract
The experiment aimed to address the issues of poor quality of individual silage made from high-moisture Desmodium intortum and waste resources of pineapple leaves, by exploring the effect of mixed silage of different proportion of pineapple leaves and Desmodium intortum on fermentation quality. The mixing ratios included: 100% Desmodium intortum (CK group), 90% Desmodium intortum and 10% pineapple leaves (10% PL group), 85% Desmodium intortum and 15% pineapple leaves (15% PL group), 80% Desmodium intortum and 20% pineapple leaves (20% PL group), and 75% Desmodium intortum and 25% pineapple leaves (25% PL group). The fermentation quality of silage was analyzed after 60 d. The results showed that the content of WSC and LA in silage were significantly increased with the increase of pineapple leaf proportion (P<0.05). Compared with CK group, the pH value and NH3-N content of silage in all treatment groups were significantly decreased (P<0.05), the crude protein loss rate was reduced, and the production of BA was eliminated. The study indicates that it is more suitable to add about 20% of pineapple leaves and Desmodium intortum mixed silage.
