This study was carried out to determine crude nutrient content and quality of silage samples made from different crops. Silages were prepared from sunflower, cowpea, sorghum and soybean silage. The effect of additives on the some parameters of silage inoculants were examined in the study. Sil-All (Alltech, UK) containing Lactobacillus plantarum, Pediococcus acidilactici, Streptococcus faecium and cellulase, hemicellulase, pentosanase and amylase enzymes were used. The following measurement were recorded on silage materials: The samples were analyzed for crude protein (CP), crude ash (CA), pH, dry matter (DM) and fleig quantitative score. As a result of this experiment, among the silages, while the highest CP were determined from cowpea silage with inoculant (15.20%), the lowest CP were determined from sorghum without inoculant (7.11%). While fleig quantitative score was the highest at sorgum silage with inoculant; fleig quantitative score was the highest at cowpea silage without inoculant.
