To study the effect of using canola meal instead of soybean meal on dry matter intake, milk yield and
composition and some blood metabolites twelve cows after calving were used. Design treatments were two diets
containing soybean meal (SBM; n = 6) or canola meal (CM; n=6). Data were analyzed using PROC MIXED of
SAS software. Results of this study showed that diets had no effect on dry mater intake, milk production and
composition. Diets containing canola meal increased milk fat. Plasma glucose, cholesterol, Blood urea nitrogen
and aspartate transaminase concentrations were similar among diets. In conclusion results from this experiment
demonstrate that substituting CM with soybean meal in the diet of early lactating cows had no adverse effect on
milk production and composition and blood metabolites, therefore using CM could be better in terms of reducing
the diet expenses
