ABSTRACT
A study was performed to ensile rice straw, and napier leftovers with rumen contents (RC), and molasses to determine the physical and nutritional properties of silages. Silages were prepared in airtight plastic containers at ambient temperature according to the treatments T0 (0% RC), T1 (5% RC), T2 (10% RC), and T3 (15% RC) with 5% molasses as dry matter basis at 0, 14, 21, and 28 days, respectively. Results showed that the physical qualities (color, odor, and softness) of silages were improved in rumen content added treatments till 28 days of ensiling period. The pH of silages was declined (p<0.05) with the enhancement of RC and ensiling period. The crude protein (CP), metabolizable energy (ME), and organic matter digestibility (OMD) were improved (p<0.05) but dry matter (DM), crude fiber (CF), ether extract (EE), and ash were declined (p<0.05) in all the treatments (T1, T2, and T3) compared to control T0. In the consideration of results among all the treatments, T2 and T3 up to 28 days were desirable for the preparation of silage. To sum up, rumen content can be utilized in rice straw and napier leftovers in silage preparation which provides a low-cost quality ruminant feed by reducing the environmental pollution.
