Abstract
This study was carried out to investigate the effect of ensiling wheat straw (WS) with addition of fermented juice of lactic acid bacteria (FJLB) prepared from wild reed plant with different sources and levels of soluble carbohydrates on changes in structural carbohydrates content and nutritive value of straw. The FJLBs were prepared by incubating wild reed plants with cane or date molasses at three levels, 0, 3, and 5% for each, and were added to WS at level of 1%, together with urea and molasses at a level of 1 and 10% respectively. The silage samples were packed in double plastic bags and kept anaerobically for 45 days. The results showed a significant decrease in the content of neutral detergent fiber (NDF, P<0.05), acid detergent fiber (ADF) and cellulose (P<0.01) in WS silage with increasing the level of soluble carbohydrates added at preparation of the FJLB. Ensiling WS with addition of FJLB prepared with a high level of those soluble carbohydrates resulted in a significant increase (P<0.01) in the in vitro digestibility of dry matter (IVDMD) and expected intake of dry matter (DMI), as well as a significant improvement (P<0.05) in the relative feed value (RFV) of the WS.
