Description
The influence of wilting on the conservation quality, intake, digestibility and nitrogen balance of silages was studied. 32 silages made from 10 fresh crops were fed to growing sheep. For each crop a direct-cut silage without additive, a direct-cut silage with formic acid and a wilted silage were prepared. Conservation of wilted silages was not as good as that of direct-cut silages with formic acid but was better than that of silages without additive. However, both intake and protein digestibility of wilted silages were the lowest of the three types. The nitrogen balance was also lower with wilted silages than with direct-cut types, especially when the nitrogen intake was high. In conclusion, utilization of nitrogen in wilted silages by growing sheep is poorer than that of direct-cut silages.
