Replacing soybean meal with canola meal – in three different rations

February 2014

Research reported in 2012 first noticed that crude protein from canola meal was used more efficiently than that found in soybean meal. With this new finding, investigators at the USDA Forage Research Center sought to compare soybean meal and canola meal in three different ratios of alfalfa-to-corn silage. The results of the research are reported in the table below.

The researchers key learnings included:

When canola meal replaced soybean meal, milk yield and protein increased.
Milk Urea Nitrogen (MUN) decreased when canola meal replaced soybean meal, leading researchers to believe canola meal protein was used more efficiently.
No interaction between protein source and forage type was noted.
Including more alfalfa silage led to increased milk production and milk components.
