This study was conducted to determine the nutritive value of sesbania Silage by using of different levels of molasses with rates 0,3 and 6% (of fresh matter basis)and ensiled for 0,20 and 40 days, after end of ensiled, the smell is acceptable and like vinegar smell in all rates of molasses and different time of ensiling, the colour of silage were green without ensiling at different levels of molasses, while at 20 and 40 days ensiling the colour be yellowish brown to brown in the treatments with molasses, No mould was seen in any silage treatment except that the 40 days ensiling, Acceptable sesbania silages were evaluated physical quality with regard to smell and colour further indicating that a high quality silage is produced.

The interaction between ensiling day and the level of molasses show significant (p<0.05) increase in IDMD and ME at 40 ensiling days with three level of molasses then at 20 ensiling days with three level of molasses compared with zero ensiling day ,there is a significant (p<0.05) decreased in pH at 40 ensiling day with three level of molasses then the 20 ensiling days with three level of molasses compared with zero ensiling days.

The values obtained after 24 hours incubation period for in vitro gas production volume show significant (p<0.05) increase at 40 ensiling days with 6% molasses, and with methane production increase high significant (p<0.01) at 40 ensiling days with 0,3 and 6% molasses, high significant (p<0.01) increase in gas production at 40 ensiling day with 0,3 and 6% molasses after 72 and 96 hours incubation period, high significant (p<0.01) increase in methane production at 40 ensiling days with 0,3 and 6% molasses after 72 and 96 hours incubation period and at 40 ensiling days with 3 and 6% molasses after 96 hour incubation period .

The estimated short chain fatty acid show a significant (p<0.05) increase at 40 ensiling days with 0,3 and 6% molasses, then at 20 ensiling days with 0,3 and 6% molasses compared with zero ensiling day with three level of molasses ,The estimated of ME and IDMD significant (p<0.05) increase in at 40 ensiling days with 0,3 and 6% molasses ,then at 20 ensiling days with 0,3 and 6% molasses compared with zero ensiling days with three level of molasses.
