Abstract

This study was carried out to evaluate the changes in chemical composition and nutritional value of Faba bean straw silage, treated with formic acid, propionic acid, and molasses. For this aim Faba bean straw were harvested and chopped with cutting length about 2 to 4 cm. The chopped common Faba bean straw were mixed with the molasses (%10), formic acid (%0/6) and propionic acid (%1) ensiled in 5 Kg plastic baskets. The silages were opened after 60 day and chemical compositions including dry matter (DM), ash, organic matter (OM), ether extract (EE), cured protein (CP), cell well and cell well without hemicelluloses fractions were measured according to the standard procedure (AOAC). Organic matter digestibility, digestibility Organic matter in dry matter and MKetabolizable energy content and dry matter, digestibility were also determined by gas production (invitro) and nylon bags (in situ) methods. Results showed that the addition of molasses caused a significant increased DM, EE, Ash, and CP content and decreased pH, NDF and ADF content respectively (p< 0/01).The addition of formic acid caused a significant increased in EE, CP, DM and ash content caused a significant decreased in pH, OM, NDF and ADF content respectively. The addition of propionic acid increased DM, EE, Ash, and CP and decreased NDF, ADF, pH and OM content respectively. The addition of supplements molasses, formic acid and propionic acid, caused significant differences in chemical composition. Results showed that the molasses, formic acid and propionic acid caused a significant increase in dry matter digestibility. In addition Gas production results showed that molasses, formic acid and propionic acid caused a significant increase in gas productions value.
