| Abstract: | A conservation experiment is described in which the losses in ensiling heavily–wilted, baled herbage of 49–58% dry–matter content in a completely sealed polythene film is described. In addition, a comparison is made between silages with and without sodium metabisulphite added as a preservative. The mean DM loss for the control silages was 11.1%, and that for the metabisulphite–treated silages 12.8 %. These losses, and the individual crude–nutrient and digestible–nutrient losses are compared with those obtained for heavily–wilted and conventional silage made in lined trench silos. Metabolizable energy values for the grass and silages are also presented. |
