英文摘要	The objective of this experiment was to evaluate the effects of replacement of whole-plant corn with oat and common vetch on the fermentation quality, chemical composition and aerobic stability of total mixed ration (TMR) silage in Tibet. Four TMR that varied in the forage sources on dry matter basis were used: (i) 52% whole-plant corn (Control); (ii) 43% oat + 12% common vetch (OC3.6); (iii) 38% oat + 18% common vetch (OC2.2); and (iv) 33% oat + 23% common vetch (OC1.5). Silos were opened on day 45 and then subjected to an aerobic stability test for 12 days. The results showed that all silages were well preserved with low pH and NH3-N, and high lactic acid and V-scores. With the increasing proportion of common vetch, crude protein, ether extract increased (P<0.05), and neutral detergent fiber and acid detergent fiber decreased (P<0.05). Under aerobic conditions, treated silages were more stable than the control silage as indicated by lower (P<0.05) pH and yeast population. It was concluded that replacement of whole-plant corn with oat and common vetch had no unfavorable effects on the fermentation quality and improved crude protein content and aerobic stability of TMR silage. OC2.2 silage was the best among three treated TMR silages.
