TL;DR: It is concluded that canola meal is at least as good as soybean meal as a protein supplement; and although studies evaluating the use of CMN and CRM for ruminants are scarce, it has been demonstrated that both oilseeds may be valuable feedstuff for livestock animals.
Abstract: Soybean meal (SBM) is a byproduct from the oil-industry widely used as protein supplement to ruminants worldwide due to its nutritional composition, high protein concentration, and availability. However, the dependency on monocultures such as SBM is problematic due to price fluctuation, availability and, in some countries, import dependency. In this context, oilseeds from the mustard family such as rapeseed/canola (Brassica napus and Brassica campestris), camelina (Camelina sativa), and carinata (Brassica carinata) have arisen as possible alternative protein supplements for ruminants. Therefore, the objective of this comprehensive review was to summarize results from studies in which canola meal (CM), camelina meal (CMM), and carinata meal (CRM) were fed to ruminants. This review was based on published peer-reviewed articles that were obtained based on key words that included the oilseed plant in question and words such as “ruminal fermentation and metabolism, animal performance, growth, and digestion”. Byproducts from oil and biofuel industries such as CM, CMM, and CRM have been evaluated as alternative protein supplements to ruminants in the past two decades. Among the three plants reviewed herein, CM has been the most studied and results have shown an overall improvement in nitrogen utilization when animals were fed CM. Camelina meal has a comparable amino acids (AA) profile and crude protein (CP) concentration to CM. It has been reported that by replacing other protein supplements with CMM in ruminant diets, similar milk and protein yields, and average daily gain have been observed. Carinata meal has protein digestibility similar to SBM and its CP is highly degraded in the rumen. Overall, we can conclude that CM is at least as good as SBM as a protein supplement; and although studies evaluating the use of CMN and CRM for ruminants are scarce, it has been demonstrated that both oilseeds may be valuable feedstuff for livestock animals. Despite the presence of erucic acid and glucosinolates in rapeseed, no negative effect on animal performance was observed when feeding CM up to 20% and feeding CMN and CRM up to 10% of the total diet.

TL;DR: Cardiac phospholipids in rats fed the rapeseed oil contained an elevated level of omega 3 docosahexaenoic acid, particularly in phosphatidylethanolamine, which appeared to be a promising oil for human consumption.
Abstract: Male Wistar rats were fed a purified basal diet with 20% lard and corn oil (3:1), sunflower oil, poppyseed oil, low-erucic rapeseed oil from Brassica napus, cultivar Tower, or mixtu

TL;DR: It was concluded that several vegetable fat sources could be used as alternatives to animal fat in pig feed, whereas fat blends should be avoided.
Abstract: Summary The use of fats and oils in diets for pigs is of great importance due to their high energy value. As a consequence of the BSE-crisis in the European Union, the amount of animal fat available for animal feeds has been reduced, and alternative fat sources are of increasing importance. In this paper, we review our main findings on the effects of diets with different fat sources on apparent fat digestibility in pigs. A method for quantitative measurement of fat extraction from feed and faeces has been developed, and this method has been used in a digestibility trial, in which diets added 5% of either animal fat, palm oil mix, palm oil, vegetable oil mix, coconut oil, or rapeseed oil were tested in weaned and growing pigs. It was concluded that several vegetable fat sources (palm oil mix, palm oil, coconut oil, rapeseed oil) could be used as alternatives to animal fat in pig feed, whereas fat blends should be avoided.

TL;DR: Mercury summer rape (Brassica napus L.) is a high-erucic acid rapeseed cultivar with canola-quality meal that is adapted to the southern B. napus growing regions of western Canada.
Abstract: Mercury summer rape (Brassica napus L.) is a high-erucic acid rapeseed cultivar with canola-quality meal. The oil provides a good source of erucic acid for industrial applications and the canola-quality meal can be used in the feed industry. Mercury has an average 10% yield advantage over Hero rapeseed with seed oil and protein contents comparable with Hero rapeseed. Mercury is adapted to the southern B. napus growing regions of western Canada. Key words: Rape (summer), high erucic acid-low glucosinolate, cultivar description

TL;DR: Brassica napus somatic hybrids with low linolenic acid (18:3) content in their seed oil have been produced using fusion partners screened for low 18:3, and the low level proved stable in the R1 generation.
Abstract: Brassica napus somatic hybrids with low linolenic acid (18:3) content in their seed oil have been produced using fusion partners screened for low 18:3. One somatic hybrid contained only 3.5% 18:3, a level significantly below the mid-parental mean. The low level of 18:3 proved stable in the R1 generation. Oil content of the lowest 18:3 selection increased from the mid-parental mean (29.3%) in the R0 generation to 36% in a R1 field bulk. The R1 field population also showed some resistance to shattering.
