The effect of different additives on Caragana korshinskii silage

The effects of additives on Caragana korshinskii silage were studied. The plants of C. korshinskii during flowering stage were harvested and ensilaged with 3 treatments: 1) CK, 2) adding formic acid (6 mL/kg) and 3) sucrose (2%), then bagged in seal bags for 360 d. The results of this study showed that the silage fermentation quality was improved with the additives of formic acid and sucrose respectively. The pH of C. korshinskii silage were decreased significantly with adding sucrose (P0.05), lactic acid content increased significantly (P0.01) and ammonia nitrogen content decreased significantly (P0.01). The lactic acid content increased significantly (P0.01) and ammonia nitrogen content decreased significantly (P0.01) with adding formic acid. The dry matter recovery of the silage increased with addition of formic acid and sucrose (P0.05) respectively. The nitrate content reduced after ensilaged.
