Abstract: The objective of this experiment was to evaluate the effects of replacing whole-plant corn with different proportions of bamboo shoot shell (BSS) on the fermentation quality, nutritional value and aerobic stability of total mixed ration (TMR) silage. There were four treatments: 0% BSS (control), 15% BSS (15%), 25% BSS (25%), 35% BSS (35%). The silos were opened at 5, 7, 14, 30 and 90 days after ensiling in order to determine the fermentation quality, nutritional and microbial compositions of the silages. Meanwhile, we estimated the aerobic stability of the silages in conjunction with recording of temperature variations using an online multi-channel data logger, and analyzed the chemical composition of samples taken at day 3, 6, 9 and 14 of aerobic exposure. As the proportion of BSS increased, the lactic acid contents decreased gradually, the pH increased significantly (P<0.05) and the ammonia/total nitrogen ratios increased gradually during the ensiling. The 15% and 25% treatments still retained a good fermentation quality as indicated by high lactic acid contents (60.16-64.94 g/kg dry matter), low pH (4.15-4.20) values, low ammonia/total nitrogen ratios (55.56-58.73 g/kg total nitrogen) and minor butyric acid contents (1.05-1.47 g/kg dry matter). During the period of aerobic exposure, the initiation of aerobic deterioration of the control silage had occurred by day 9, as indicated by a dramatic rise in the pH and a decline in the lactic acid, acetic acid and water soluble carbohydrate content, and the temperature increased more than 2℃ above the environment temperature after 195 h of exposure to air. However, for the BSS treatments, the increase in pH and the decline of lactic acid, acetic acid and water soluble carbohydrate contents occurred more slowly than in the control. In addition, the temperature of the silages containing BSS increased no more than 2℃ above the environment temperature within the 14 days of aerobic exposure, which indicated that the BSS treatment significantly improved the aerobic stability compared to the control, but may have decreased the feeding value. Overall, the 15% and 25% treatments showed not only better fermentation quality but also higher aerobic stability compared to other BSS treatments. From the perspective of maximizing the use of BSS resources, it is suggested that the most appropriate replacement level of BSS is 25% in whole-plant corn TMR silage.
