Abstract

The aim of this study was to determine the effects of different absorbents and corn on fermentation characteristics and quality of potato vines silage. The experiment used a simple factor design, there were 7 groups and 5 replicates in each group. The control group was silage with potato vines alone; groups 1 to 3 were supplemented with 25% bran, maize stock and wheat straw based on control group, respectively; groups 4 to 6 were supplemented with 4% corn based on groups 1 to 3, respectively. The results showed that compared with the control group, the score of quality of groups 1 to 3 was significantly increased (P<0.05), the pH was significantly decreased (P<0.05); the lactic acid content of groups 1 and 2 was significantly increased (P<0.05), the ammonia nitrogen content was significantly decreased (P<0.05). Supplemented with different absorbents and corn had significant effect on nutrients of potato vines silages (P<0.05). In conclusion, added corn based on the absorbents, the fermentation quality of silage is improved further. No matter whether corn is added, the effect of rice bran is the best, the second is maize stalk and the worst is wheat straw.

Key words： potato vine; absorbent; corn; silage
