The world population is estimated to reach 9 billion people by 2050, which is estimated to increase the demand for food, fuel, and fiber by 60%. Domesticated ruminants play a vital role in this scenario because they can consume food byproducts that are nonedible for humans, contributing to livestock sustainability. Meals extracted from oilseed plants, such as soybean, canola, carinata, and camelina, are examples of food byproducts. Soybean meal is likely the byproduct most used worldwide, due to its availability and high-quality nutritional composition. However, the dependency on monocultures such as soybean is problematic due to price fluctuation and, in some countries, import dependency. Canola, camelina, and carinata meals have been investigated in the past two decades. Therefore, we aimed to summarize the results from studies in which canola, camelina, and carinata meal were fed to ruminants in order to evaluate how comparable these are to soybean meal and other common protein supplements in terms of animal digestion and performance. Based on this review, we conclude that canola meal is at least as good as soybean meal; and that camelina and carinata meal can be a valuable alternative feedstuff for livestock animals.
