TL;DR: Crambe has great potential to, at least, partially replace HEAR as a source of erucic acid, if the current knowledge-gap in agronomic management and crop improvement (seed yield and quality) can be addressed.
Abstract: Crambe (Crambe abyssinica Hochst) is an oilseed crop in the Brassicaceae family. Crambe’s ability to survive in diverse environmental conditions, its unique oil composition, the high oil content, suitability for the production of slip agents for plasticizers, the capacity to be easily included in common crop rotations, and its adaptability to equipment used for small grain cultivation has renewed the interest in this emerging crop. Crambe is considered one of the main sources of erucic acid, which can be up to 60% of its seed oil content. Erucic acid (C22:1) is a fatty acid with industrial importance since it is used to produce erucamide, key ingredient in the plastic industry. Inclusion of crambe into crop rotations can be beneficial because of its short life cycle, low fertility requirements, resistance to pest and diseases, and relative drought tolerance. Currently high erucic acid rapeseed (Brassica napus L.) (HEAR) is the principal source for erucic acid. However, the risk of contaminating food quality rapeseed (i.e., canola) by cross-pollination and the negative impact on climate, due to high inputs, are potential limitations to expand HEAR cultivation. Crambe has thus great potential to, at least, partially replace HEAR as a source of erucic acid, if the current knowledge-gap in agronomic management and crop improvement (seed yield and quality) can be addressed. Seed yield needs to be increased to be able to compete with HEAR. In addition, reducing glucosinolates and fiber in crambe meal may increase its inclusion in monogastrics rations. The objective of this review was to compile and summarize new and existing information on agricultural practices in crambe production and management to identify gaps in knowledge and areas for future research to increase the cultivation of crambe.

TL;DR: The nutritional value of canola and mustard press cakes obtained from the biodiesel industry as ingredients for use in diets fed to broiler chickens was compared and feed conversion was significantly improved for birds fed either canola or mustard biodiesel press cake compared with canola meal.
Abstract: This study compared the nutritional value of canola (B. napa) and mustard (B. hirta) press cakes obtained from the biodiesel industry as ingredients for use in diets fed to broiler chickens. A total of 210, one-day old, male broiler chicks were randomly assigned to one of seven dietary treatments. The control diet was based on wheat and soybean meal and contained 15% canola meal. For the experimental diets, 5, 10 or 15% of the canola meal was replaced with an equal amount of either canola or mustard biodiesel press cake. Dry matter and neutral detergent fiber digestibility were significantly higher for birds fed diets containing either canola or mustard biodiesel press cake compared with canola meal. Dry matter and neutral detergent fiber digestibility of the canola biodiesel press cakes was higher than the mustard biodiesel press cakes. Ether extract digestibility and nitrogen retention were significantly higher for birds fed canola biodiesel press cake compared with canola meal and mustard biodiesel press cake. Body weight gain and feed intake did not differ between birds fed canola or mustard biodiesel press cake and canola meal. In addition, there was no significant difference in body weight gain or feed intake between birds fed diets containing canola or mustard biodiesel press cake. Feed conversion was significantly improved for birds fed either canola or mustard biodiesel press cake compared with canola meal. Mortality was unaffected by treatment. Since the performance of broilers fed canola biodiesel press cakes was essentially the same as that of broilers fed canola meal, it is difficult to justify a premium to be paid for canola biodiesel press cake over that paid for canola meal. In addition, there was no difference in the performance of broilers fed biodiesel press cake obtained from canola or mustard seed. As mustard seeds are generally available at a lower price than canola seed, there may be some incentive to use mustard rather than canola seed for producing biodiesel press cake for use in poultry production.

TL;DR: Canola and rapeseed are oil-rich seeds, and their global production ranks third among other oilseed crops after oil extraction, a meal containing about 40% protein is obtained The quality of canola meal as represented by its amino acid composition is well balanced for human food use as discussed by the authors.
Abstract: Canola and rapeseed are oil-rich seeds, and their global production ranks third among other oilseed crops After oil extraction, a meal containing about 40% protein is obtained The quality of canola meal as represented by its amino acid composition is well balanced for human food use (Ohlson 1978) Through successful plant breeding, double-low varieties of rapeseed (canola) are now in production in Canada and some European countries These varieties contain less than 2% erucic acid in their oil, and less than 30 µmol of any one or combinations of two or more of four aliphatic glucosinolates per gram of their moisture-free, defatted meal (see below)

TL;DR: In 2015, China was the world's second most important producer of rapeseed after Canada, with 7.59 million hectares under cultivation and a production of 14.1 million tons as mentioned in this paper.
Abstract: In 2015, China was the world’s second most important producer of rapeseed after Canada, with 7.59 million hectares under cultivation and a production of 14.1 million tons. It is also a major importer of rapeseed grain, as well as the premier consumer. Currently, its R&D remains mainly public. Its rapeseed seed market is slightly superior to 2.7 billion RMB (362 million €) and concerns partly hybrid varieties Nevertheless, the improvement in living standards and the strong development of animal production in China has brought with it an increasing dependence on oil and protein crops, notably rapeseed but especially soybean and palm.
