Abstract: The experiment was conducted to determine the effects of different corn meal addition levels on the silage quality of osier peel, and to discuss the appropriate level of corn meal addition.According to one-factor complete randomalized experimental design, there were 4 treatments groups which the corn meal addition levels were 0%(control group)、5%(group Ⅰ)、10%(group Ⅱ)and 15%(group Ⅲ), respectively.The general nutrient contents and fermentation quality were determined and the comprehensive scores of fermentation quality were evaluated after ensiling for 60 days.The results showed as follows:When corn meal addition amounts increased in osier peel silage, CP contents tended to raise, then dropped down, NDF and ADF contents declined gradually.Comparing with group Ⅰ、Ⅱ、Ⅲ, the pH and NH3-N/TN of silage in control group were the highest which were 4.76% and 11.09%, repectively, and that were increased by 18.70% and 98.75%、18.11% and 96.63%、16.95% and 85.76%, respectively, WSC contents was decreased by 53.21%(P<0.05)、54.61%(P<0.05)、58.26%(P<0.05), respectively.The score of both sensory evaluations and comprehensive assessments of fermentation quality were group Ⅰ>group Ⅱ>group Ⅲ>control group.According to the results obtained from sensory evaluations and comprehensive assessments of fermentation quality in this trial conditions, we concluded that the optimum supplement dosage of corn meal was 5% in osier peel silage.
