Extract

Canola meal (CM) is a commonly used protein supplement for ruminants, the proteins of which are extensively degraded in the rumen. Attempts to decrease the rate and extent of ruminal degradation of canola meal proteins have used physical and chemical treatments (Sadeghi and Shawrang, 2006). However, most of these treatments adversely affect the protein digestibility of the final product in the small intestine. Ethanol treatment appears to be superior in that it alters protein degradability without reducing its intestinal digestibility. No information is available concerning effects of ethanol treatment on ruminal crude protein (CP) degradation and type of true proteins of canola meal that leave the rumen undegraded. Therefore, the objectives were to investigate the effects of ethanol treatment at levels of 500, 600 or 700 ml/l on protein degradability and intestinal digestibility of CM, and to monitor the fate of true proteins of treated CM in the rumen.
