Study on the Relationship between Fermentation-Accumulated Temperature and Nutrient Loss of Whole-Plant Corn Silage

The nutrition loss of silage is partly due to the heat production of silage. In this study, the amount of nutrition loss of silage was estimated by measuring the heat production of silage, and the concept of the accumulated temperature of fermentation was put forward. The laboratory measured the fermentation-accumulated temperature of whole-plant corn silage with different compaction densities. The samples were analyzed to establish a multiple linear regression model with nutrition loss. The results demonstrated a significant non-linear relationship between the whole-plant corn silage compaction density and fermentation-accumulated temperature. The multiple linear regression model between the accumulated-fermentation temperature and nutrition loss was significant under different densities. The amount of silage nutrition loss can be predicted by the fermentation-accumulated temperature.
