A study was conducted to determine differences in chemical composition and ruminal degradability of oat hulls derived from ten oat varieties. Hulls derived from AC Assiniboia had a lower (P < 0.05) acid detergent lignin (ADL) and a higher (P < 0.05) in vitro dry matter disappearance (IVDMD) relative to the other nine varieties. Effective ruminal degradability of neutral (NDF) and acid (ADF) detergent fiber for AC Assiniboia hulls were higher (P < 0.05) than those of Calibre hulls and similar to those of Calibre straw.
