French and Canadian researchers have found that dairy cows do just fine when canola meal replaces soybean meal or distillers grains in the diet.

In an experiment involving eight rumen-fistulated Holstein cows, milk production, dry matter intake and components did not vary significantly between diets containing canola meal, soybean meal or high-protein corn distillers grains as the single protein supplement, they write in the December 2013 edition of the Journal of Dairy Science.

The researchers also commented favorably on the feeding value of canola meal. A canola meal diet resulted in a better quality of metabolizable protein supply than the soybean meal and high-protein distillers grains diets, they point out. And canola meal presented no deficiency in a single essential amino acid, as soybean meal did for methionine or high-protein corn distillers grains did for lysine.
