Mustard meal might be a valuable ingredient for the swine industry domestically and internationally. In some export markets, concerns exist regarding the voluntary feed intake of pigs fed mustard instead of canola meal in their diets. This study will therefore compare two diets with either mustard meal or canola meal in the diet at a 15% inclusion rate for 28 days. This would be enough to assess if the feed intake concerns are indeed valid, or not and if growth performance differences exist. Pigs fed mustard meal tended to have a 5% better growth performance and had a 2.5%-unit better feed efficiency and an equal feed intake than pigs fed canola meal. Mustard meal might thus be a good opportunity ingredient with minimally a nutritional value equal as canola meal and might be a worthwhile opportunity ingredient to consider during periods of high prices for protein sources.
