Abstract
Three experimental silages were formulated from 59% date palm leaves, 40% discarded date palm fruit and 1% Urea, then it was divided into three different parts. The first, control without inoculant; second, inoculated by Enterococcus faecium; third, inoculated by Lactobacillus plantarum and opened on 0, 7, 21, 40 and 60 days of ensiling. Results showed that inoculated silages with E. faecium and L. plantarum were led to significant (P<0.05) in contents of CP, EE, NFE and NFC and significant (P<0.05) decrease in contents of CF, NDF, ADF, ADL, cellulose and hemicellulose compared to the control silage. The pH value of silage was lower significantly (P<0.05) with E. faecium and L. plantarum treated silage contrasted to control silage. Concentrations of lactic, acetic and propionic acids were significantly (P<0.05) the highest, however the concentrations of butyric acid and ammonia-N were significantly (P<0.05) the lowest in silage inoculated with L. plantarum followed by silage inoculated with E. faecium, however the lowest values were done in untreated control silage, The counts of E. faecium inoculant increased up to 21 days of ensiling and L. plantarum inoculant increased up to 40 days of ensiling and decreased afterwards. Counts of E. faecium strain was the highest at 21 days of ensiling, whereas, the highest counts of L. plantarum strain was at 40 days of ensiling. The counts of Enterococci and Lactobacillus increased significantly (P<0.05) in inoculated silages in comparison with uninoculated silage. Enterococci rich the highest counts at 21 days of ensiling in L. plantarum inoculated and at 40 days of ensiling in E. faecium inoculated silage. Meantime, the counts of Lactobacillus rich the highest counts at 7 days of ensiling in L. plantarum inoculated silages and at 21 days of ensiling in E. faecium inoculated silage. However, uninoculated silage recorded significantly (P<0.05) higher counts of Enterococci and Lactobacillus at 60 days of ensiling in compared to inoculated silages. Predicted dry matter intake (DMI) as a percentage of live body weight (LBW), dry matter digestibility (DMD), relative feeding value (RFV), relative forage quality (RFQ), digestible energy (DE) and total digestible nutrients (TDN) were significantly (P<0.05) higher with E. faecium and L. plantarum inoculated silages compared to uninoculated control silage. However, gross energy (GE) did not affected significantly by bacterial inoculants.
