Extract

The dry matter (DM) and water soluble carbohydrate (WSC) concentrations of forage are the main characteristics influencing the course of silage fermentation. Knowledge of these parameters would enable decisions to be made both on the need for additive and the type of additive likely to be most effective. Moreover, the degree of wilt could also be followed in wilted crops. The present study was directed to assessing the relationship between the composition of the crop and the volume and composition of the expressed juice. The ultimate objective was the development of on-farm methodology for predicting the ensiling characteristics of crops.
