<p>In silages made from corn and sorghum species, the silage protein ratio ranges between 7-10%. This rate,</p><p>which symbolizes a relatively low value, is also possible to increase naturally by silage together with</p><p>legume forage crops.</p><p>The experiment was carried out to evaluate on the effects of different levels (25 and 50%, based on dry</p><p>matter) of various leguminous (Lathyrus sativus, Pisum arvense, Vicia sativa, V.villosa, V.faba var. minor</p><p>and Trifolium resupinatum) hays added to switch grass (Panicum virgatum) at ensilage on the silage</p><p>quality and nutritive value.</p><p>Fifty-two vacuumed nylon bag silos were used. A complete randomized design was used with four</p><p>replications. After 60 days of ensilage period, some properties of silages were determined considering dry</p><p>matter (DM) content, pH values, crude protein (CP) and ash content.</p><p>The results demonstrated that there were statistically significant differences between the added groups for</p><p>above-mentioned traits compared to the control. pH values of silages increased as levels of hays increased.</p><p>The addition of leguminous hays of 25% or 50% to silage increased crude protein content about 2% or 5%</p><p>compared to the control (pure switch grass silage), respectively.</p><p>While the lowest pH value was 4.23 at the mixture with 50% switch grass + 50% forage pea, the highest</p><p>pH is 5.37 it has been observed that it belongs to 50% switch grass + 50% Persian clover silage.</p><p>The highest dry matter content was 27.7% at the pure switch grass silage (100% switch grass + 0%</p><p>legume). In 50% switch grass + 50% Persian clover silage; dry matter content was the lowest (20,5%).</p><p>Crude protein (CP) content of the silages increased by increasing rate of legumes. While the minimum</p><p>crude protein content was found in the pure switch grass silage (%6.8), the highest crude protein</p><p>concentration (12.3%) was obtained from the mixture with 50% switch grass + 50% common vetch.</p><p>The highest crude ash content is in the mixture 10.2% (50% switch grass + 50% Persian clover silage,</p><p>while the lowest content is 6.8% (50% switch grass + 50% horse bean. ) belongs to the mixture.</p><p>Keyword: Switch grass, leguminous hay, silage mixture and quality.</p>
