A study on fermentation quality of mixed silages of hulless barley straw and perennial ryegrass in Tibet

Abstract

Abstract: The fermentation quality of mixed silages of hulless barley (Hordeum vulgare) straw and perennial ryegrass (Lolium perenne) was studied using the following treatments: control (100% hulless barley straw), L (80% hulless barley straw+20% perennial ryegrass), M (60% hulless barley straw+40% perennial ryegrass) and H (40% hulless barley straw+60% perennial ryegrass). The laboratory silos were opened on 7, 14 and 30 days after ensiling in triplicate and the fermentation quality was measured. The mixed silages significantly (P<0.05) increased lactic acid and water soluble carbohydrate contents, while significantly (P<0.05) reducing pH value and dry matter content. Acetic acid content was significantly (P<0.05) increased with an increase of perennial ryegrass in mixed silages. The ammonia/total nitrogen of mixed silages was lower (P>0.05) than that of the control. There was little butyric or propionic acids in all silages. Based on these results, mixed silage of 40% perennial ryegrass was best for improving the fermentation quality of hulless barley straw.
