The objective of the present study was to evaluate the effect of moisture content on the haylage quality of Italian ryegrass (Lolium multiflorum). Seven levels of moisture content (60%, 55%, 50%, 45%, 40%, 35%, and 30%) were tested in this experiment. The results show that the feed value, crude-protein content, neutral detergent fiber, acid detergent fiber, and in vitro dry-matter digestibility were not significantly different as the moisture content decreased. The pH and lactic-acid content, however, decreased significantly as the moisture content decreased, whereas the content of acetic and butyric acid increased significantly. We concluded that a moisture content within a range from 60% to 40% is best for Italian-ryegrass haylage.
