“…A utilização de farelo de crambe na alimentação animal vem sendo estudada principalmente para ruminantes como bovinos de corte (Mendonça et al, 2015), bovinos de leite (Oliveira et al, 2016) e ovinos (Goes et al, 2010;Dorigon e Gai (2016), entretanto, são escassos os estudos para os não ruminantes, havendo alguns trabalhos com juvenis de jundiá (Lovatto et al, 2014;Pettro et al, 2014), tilápias do Nilo (Moura et al, 2015) e frangos de corte (Ledoux et al, 1999). Portanto, objetivou-se com o presente trabalho determinar o desempenho de frangos de corte na fase inicial de vida, alimentados com farelo de crambe como fonte proteica para a ração.…”

Alimentos alternativos. Fatores antinutricionais. Fibra bruta.resUMo Um experimento foi conduzido com o objetivo de avaliar a substituição da proteína da ração pela proteína do farelo de crambe (Crambe abyssinica) sobre o desempenho dos frangos de corte na fase inicial (oito a 21 dias). Foram utilizados 420 pintos machos da linhagem Cobb 500®, distribuídos em delineamento experimental inteiramente casualizado com cinco tratamentos e quatro repetições de 21 aves por unidade experimental. Os tratamentos experimentais constituíram de uma ração testemunha sem o farelo de crambe e os demais pela substituição da proteína da ração nos níveis de 5, 10, 15 e 20%. Não houve efeito significativo para conversão alimentar dos frangos, no entanto, observou-se efeito linear decrescente para o consumo de ração e o ganho de peso das aves, à medida que a proteína do crambe substituiu a proteína da ração. Verificou-se redução do consumo de ração aos níveis de 10, 15 e 20% de substituição da proteína. Para o ganho de peso, os menores valores observados foram para os níveis de 15 e 20% de substituição, enquanto que os níveis de 5 e 10% não diferiram em relação ao tratamento testemunha. Portanto, recomenda-se a substituição do farelo de crambe na ração até o nível de 10% por não influenciar negativamente no ganho de peso dos frangos de corte.inforMation Cronología del artículo. Recibido/Crambe (Crambe abyssinica) meal in diets for broilers chickens sUMMarY A experiment was conducted to evaluate the substitution of the crude protein from the ration for the protein from crambe (Crambe abyssinica) meal on the performance of broilers in starter phase (eight to 21 days). A total of 420 male chicks of the Cobb strain were used, distributed in a completely randomized design, with five treatments and four replications of 21 broilers each. The experimental treatments consisted of a control diet without the crambe meal and other substitution of protein from ration for crude protein from crambe meal in levels of 5, 10, 15 and 20%. There was no significant effect for the feed conversion of the chickens, however, there was a decreasing linear effect for feed intake and weight gain of the birds, to the extent that crambe protein replaced the protein ration. A Reduction in the feed intake at 10, 15 and 20% levels of protein substitution was observed. For the weight gain, the lowest values observed were for the 15 and 20% replacement levels, whereas the levels of 5 and 10% did not differ in relation to the control treatment. Therefore, it can be recommended to replace the crambe meal in the feed level of 10% without negatively influencing the weight gain of broilers. additional keYwordsAlternative foods.

“…New technologies for glucosinolate detoxification, such as chemical and physical treatments, reducing the amount to 450 mg kg −1 DM on crambe meal, could allow the full substitution of soybean meal in ruminant diets [98]. Recent studies reported that crambe meal can be valuably included in fish diets (i.e., silver catfish, Rhamdia quelen) as sustainable replacement of fish meal [27,28].…”

Crambe (Crambe abyssinica Hochst): A Non-Food Oilseed Crop with Great Potential: A Review

et al. 2020

View full text Add to dashboard Cite

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.

“…On the other hand, untreated CM can be used in broiler chicken diets at low levels (50-100 g kg −1 ) without or with minimal adverse effects on weight gain and health (Ledoux et al 1999). Additionally, no differences in growth or biochemical parameters were observed in jundiá, Rhamdia quelen, fed diets containing 208.4 g kg −1 of untreated CM, compared with a control diet (0% CM) (Pretto et al 2014).…”

“…Its byproducts (crambe meal/cake) are arousing interest from companies, research institutions and universities as an alternative feedstuff in animal production (Pitol et al 2010). Defatted crambe meal/cake originating from the dehulled seeds has potential as alternative feedstuff for ruminants (Araújo et al 2018; Moura et al 2017) and non-ruminant animals (Barbosa et al 2017;Pretto et al 2014;Vieira et al 2020) due to its high protein content (280-460 g kg −1 CP) and well-balanced amino acid pro le (Baker et al 1977;Carlson and Tookey 1983).…”

This study evaluated the apparent digestibility coefficient (ADC) of crambe meal (CM) and its potential to partially replace soybean meal (SM) protein in Nile tilapia diets. The ADC for dry matter, crude protein, ether extract, energy, amino acids, calcium and phosphorus of CM were assessed in fish (n=80; 65.30 ± 5.32 g). Subsequently, an 80-day feeding trial was conducted with Nile tilapia (n=140; 6.04 ± 0.25 g) randomly distributed in 20 experimental cages (70 L; seven fish cage-1) allocated in five circular tanks (1000 L) in recirculation water system, to evaluate the effects of replacement of SM by CM (0, 6, 12, 18 and 24% in isonitrogenous and isoenergetic diets) on growth, blood parameters, fillet yield and proximal composition. The CM shows good digestibility of protein (0.824) and amino acids (0.844) by Nile tilapia and its inclusion in the diet does not affect carcass and fillet yield or proximal composition. Fish fed diets with 24.0% of the SM replaced by CM showed the worst weight gain and feed conversion rate. The protein efficiency ratio decreased in fish fed diets with 12.0, 18.0 and 24.0% of the SM replaced by CM. Hemoglobin, mean corpuscular hemoglobin concentration, total plasma protein, glucose and alanine aminotransferase enzyme activity trend to increase at highest levels of CM in the diet. In conclusion, CM has potential to replace SM in Nile tilapia diets, due to high digestibility of protein and amino acids. However, anti-nutritional factors present in untreated CM interfere on the growth and nutrient utilization of Nile tilapia.
