Treatment of canola meal (CM) with 5 or 10% lignosulfonate (LSO 3 ) for 1 or 2 h at 100 °C increased borate-insoluble CP and neutral-detergent-insoluble nitrogen and decreased in vitro ammonia concentration compared with untreated or heated CM. Acid-detergent-insoluble nitrogen was increased in 2% xylose and 10% LSO 3 CM heated for 2 h. Ruminal degradability of CP was reduced by heating CM (P < 0.01), and this effect was more pronounced (P < 0.001) with LSO 3 or xylose. Key words: Cattle, canola meal, lignosulfonate, rumen undegradable protein
