Canola meal has increasingly become a common feed ingredient in dairy diets. Despite its growing use, there are still misconceptions about its nutrient composition and applications. Understanding its full nutrient profile is key for producers and nutritionists when comparing feed ingredients to make informed decisions. Essi Evans, Ph.D., E+E Technical Advisory Services debunks three popular myths.
The first myth is that your tried-and-true resources are good/accurate. As global demand for canola oil and meal rises, it’s important to use the most up-to-date research when considering canola meal for dairy rations. Many producers rely on outdated tabular data for feed values, which can lead to misconceptions. Newer varieties of ingredients or methods of protein analysis, such as for canola meal, may not be reflected in older data. For example, recent research reveals that canola meal is an excellent source of escape protein, contrary to past beliefs. Additionally, consulting other farmers and conducting on-farm trials can provide valuable insights into canola meal’s effectiveness.
The second myth is that canola meal is just for lactating cows. Canola meal can also be fed to calves, growing heifers, and dry cows. Though it’s highly palatable after weaning, canola meal is less common in calf starter diets due to concerns about initial acceptance. However, research shows calves eat similar amounts of canola meal compared to other proteins. Sweeteners can improve pre-weaning acceptance. Studies also show canola meal supports healthy gut and rumen development. In trials, calves fed canola meal had better rumen health and showed no decline in digestibility when canola meal replaced soybean meal.
The third myth Evans debunks is that canola meal’s energy value is too low for early-lactation cows. Many producers and nutritionists mistakenly believe it has a low energy value due to outdated information in publications and feed formulation programs. In reality, canola meal, like most concentrate ingredients, is a strong energy source. Since 2016, four studies have shown that cows fed canola meal during early lactation produced higher milk yields.
Canola meal is an excellent protein source for dairy cow and calf diets, offering economic benefits by reducing feed costs and boosting productivity. It should be a key consideration when formulating rations. You can find more information at canolamazing.com and you can download the Canola Meal Dairy Feeding Guide.
