“…But, after detoxification with different processing methods, it has been used in the feed of different animals at 50–200 g kg −1 dietary inclusions, viz. cattle, 25 poultry, 26,27 and fish 28 . Different detoxification strategies, such as physical methods (dry and moist heating), use of chemicals, fermentation with microbes, and protein extraction were applied to minimize the ricin content 19,25,29–31 …”

Castor protein isolate (CPI) was prepared by aqueous solubilization of defatted castor kernel meal under alkaline conditions (pH 12.0), with precipitation at the isoelectric point (pH 5.0) followed by heat treatment. Five experimental diets were prepared by substituting soybean protein isolate (SPI) at 0%, 25%, 50%, 75%, and 100% with CPI based on protein equivalent basis. The diets were assigned as control, PI25, PI50, PI75, and PI100, respectively. A 60‐day feeding trial was conducted following a completely randomized design. Results revealed significant improvement in growth rates, feed conversion, and protein retention in Labeo rohita fingerlings (P < 0.05) at 124.50 g CPI kg−1 diet (PI75). However, these were similar between control and PI100 (P > 0.05). Dietary CPI did not alter the hepatosomatic index, viscerosomatic index, survival, carcass composition (except crude protein), and digestive enzymes (P > 0.05). The metabolic enzymatic profile of rohu fingerlings was significantly affected due to dietary treatments (P < 0.05) but oxidative stress enzymes were not affected by feeding of CPI. The activity of the aminotransferases, lactate dehydrogenase, and malate dehydrogenase did not differ (P > 0.05) between control and PI100. The preparation of protein isolate is therefore a way forward for the effective valorization of toxic castor meal and could be used at 164.0 g kg−1 inclusion (complete substitution of soybean protein isolate) in the diet of L. rohita. © 2021 Society of Industrial Chemistry and John Wiley & Sons Ltd.

“…One of the main advantages of using castor (Ricinus communis) byproducts in ruminant feeding is its high protein value. Soybean meal (SM) is a feedstuff primarily intended for human consumption, thereby increasing its production costs (Oliveira et al, 2010a;Borja et al, 2017). According to Akande et al (2015), castor cake contains from 342 to 480 g of crude protein (CP) per kilogram of dry matter; however, after the detoxification process, this CP content may decrease depending on the alkaline product used; the true protein may be insoluble in neutral detergent (Oliveira et al, 2010b).…”

The objective was to evaluate the intake, digestibility, nitrogen balance, and metabolic profile of lactating goats fed diets containing detoxified castor cake (DCC) by alkaline solutions during 150 days of lactation. Twenty-four Saanen and Anglo Nubian goats, approximately 17 months old (first lactation) and body weights of 43±2.97 kg, were distributed in a completely randomized block design with eight replicates. Treatments consisted of three diets, one containing soybean meal (SM) and two others containing DCC, with calcium hydroxide [Ca(OH) 2 ] and sodium hydroxide (NaOH). The diets significantly influenced the intake of dry matter (DM), crude protein (CP), ether extract (EE), neutral detergent fiber (NDF), and total digestible nutrients (TDN). We observed a higher dry matter intake (DMI) in goats fed SM, similar to that of goats fed Ca(OH) 2 DCC. Intake of nutrients followed the same trend as DMI. There was no significant effect of diets on digestibility of DM, CP, EE, and NDF; however, we observed a significant effect of diets on the levels of nitrogen intake (NI) and urinary nitrogen (UN). The goats fed SM consumed a larger quantity of nitrogen, but all had the same nitrogen balance, indicating that goats fed DCC were more efficient. The diets did not influence renal and hepatic parameters. Inclusion of castor cake in the diet of goats in confinement is an attractive option, considering that goats fed DCC present lower feed conversion, and its use does not cause hepatic and renal alterations, suggesting that SM can be completely replaced.

“…Nos trabalhos como os de Kim et al (2006) e Anandan et al (2005), foram utilizados equipamentos caros, como máquinas extrusoras e autoclaves, que, em alguns casos, comprometem a viabilidade do sistema de produção. Recentemente, Borja et al (2017) desenvolveram um processo de destoxificação misto, no qual o farelo de mamona passa por interações entre o tempo de autoclavagem e a quantidade de CaO. Os autores observaram que é possível reduzir o nível de CaO para 10g/kg quando associado ao tempo de autoclavagem de 30 minutos, culminando na destoxificação total do farelo de mamona.…”

RESUMO Objetivou-se avaliar a destoxificação da torta de mamona bruta (TMB), por meio de dois produtos alcalinos em diferentes concentrações, e seus efeitos sobre a composição química, a degradabilidade in situ da MS e o fracionamento de proteínas. Utilizou-se o hidróxido de cálcio [Ca(OH)2] e o hidróxido de sódio (NaOH) em duas concentrações (60 e 90 gramas), diluídos em quatro quantidades de água (1.000; 1.500; 2.000 e 2.500mL de água por quilo de TMB). Observou-se que, das diferentes concentrações utilizadas, somente a utilização de 90 e 60 gramas de Ca(OH)2 e NaOH, respectivamente, conseguiu destoxificar 100% da TMB, ambas diluídas em 2.000mL de água. Por outro lado, ao avaliar o tempo mínimo de contato dos reagentes com a TMB para uma máxima destoxificação, observou-se que três horas de contato é o tempo necessário para os reagentes diminuírem em 100% as proteínas citotóxicas, além de não deixar atividade hemaglutinante nesse material. A destoxificação com o NaOH proporcionou maior degradação das proteínas solúveis e da matéria seca, favorecendo a disponibilização do nitrogênio não proteico, estando sua aplicação em escala industrial na dependência de estudos sobre viabilidade operacional e econômica.
