“…Regarding the ether extract apparent digestibility (EEAD), there was an increase when animals received a supplement with oils, probably due to the higher ether extract intake (EEI), similar to results found by Maia et al (2010), who also reported higher EEAD when animals were fed "licuri" or castor oil.…”

“…In all diets analyzed, there was a good amount of fiber (500 g of hay/kg of DM) in the diet, which may have contributed to these results, once the fiber content possibly competed with the binding of fatty acids to the food particles in the rumen, thus preventing interference on ruminal fiber digestion (Bateman & Jenkins, 1998). Maia et al (2010) evaluated different contents (30 and 50 g/kg of DM) of "licuri" or castor oil in diets of lactating goats with 470 g of hay/kg of DM and did not observe changes in the apparent digestibility of DM. Similarly, Palmquist & Griinari (2006) did not find adverse effect on ruminal fermentation with the addition of a combination of sunflower and fish oils in cattle diets with 600 g of fiber/kg of DM.…”

“…Corroborating this study, Maia et al (2010) evaluated the addition of 30 or 50 g of "licuri" or castor oil/kg of goat diets with 470 g/kg of roughage and did not report reduction of DM intake and nutrients when 30 g of castor oil/kg were offered to animals in the total diet.…”

The objective in this experiment was to determine the effects of feeding diets with canola, sunflower or castor oils on intake, nutrient apparent digestibility and ruminal constituents of crossbred Dorper × Santa Inês sheep. Four rumen-cannulated animals of 90.2±11.4 kg average body weight were assigned to a 4 × 4 latin square. Animals remained individually in cages for the metabolism assay and were fed diets containing roughage at 500 g/kg and concentrate based on ground corn and soybean meal also at 500 g/kg. No oil was added to the control diet, whereas the others had canola, sunflower or castor oils at 30 g/kg (DM basis). There was no difference for the intake of DM and nutrients, except for ether extract, which was greater when animals received oil. The digestibility coefficients of dry matter, organic matter, crude protein, non-fiber carbohydrates and neutral detergent fiber were not changed; however, the addition of oil increased the ether extract digestibility. The values of total digestible nutrients (TDN, g/kg of DM), digestible energy (DE, Mcal/kg of DM), TDN intake and DE intake also did not change with the addition of lipids. Concerning the ruminal constituents, the addition of vegetable oils reduced the concentrations of acetate, butyrate and total short-chain fatty acids. Adding canola, sunflower or castor oils at 30 g/kg in diets with 500 g roughage/kg and 500 g concentrate/kg does not impair the intake or digestibility of nutrients in sheep, although it reduces the concentration of short-chain fatty acids in the rumen

“…Fonseca and Soto-Blanco (2014), also highlight the toxic potential of this glycoprotein, mentioning its possible use as an agent of war or bioterrorism. It is important to note that the processed oil itself is not toxic since ricin, the toxic protein, is largely removed during the extraction process (Maia et al 2010). The inhabitants of the Franco rural community know the danger that the species represents, mainly for children and domestic animals.…”

In this article, we investigate the biocultural behavior regarding the use of species of the Euphorbiaceae in the Franco community, Cocal, Piauí State, located in the Semiarid Region of Brazil. For the study, we performed 19 interviews with the home gardens maintainers based on semi-structured interviews, and calculate the Use Value (UV) for each species mentioned by the interviewees. In addition, the importance of socioeconomic factors in this type of biocultural behavior was evaluated. Seven species of the Euphorbiaceae with biocultural emphasis were mentioned, distributed across four genera, which are cultivated for various purposes, including food, medicine, fuel, animal fodder, commercial sale, cultural uses, and others. The species Ricinus communis (“mamona”) presented the highest UV (7.0). Socioeconomic factors did not influence biocultural behavior associated with the use of plants of the botanical family studied. Our findings suggest that documented biocultural attitudes are essential to ensuring the resilience and conservation of biological and cultural diversity.

“…A extração inicial é feita por preensagem mecânica, removendo apenas cerca de 45% do óleo presente nas sementes, e a obtenção do restante de óleo ocorre por meio de solventes como hexano, heptano, éteres de petróleo (OGUNNIYI, 2006). O óleo obtido não contém a toxina ricina, pois a proteína da semente permanece no subproduto da extração (MAIA et al, 2010).…”

ResumoA mamona (Ricinus communis) é um arbusto da família Euforbiacea cultivada para a obtenção do óleo das sementes. Este óleo apresenta amplo emprego industrial, com destaque para o biodiesel. No entanto, as sementes de mamona apresentam uma potente toxina, a ricina. Trata-se de uma glicoproteína altamente tóxica com ação inativadora de ribossomos. A ação tóxica da ricina é decorrente da inibição da síntese proteica nas células eucarióticas, ocasionando a morte celular. Apenas uma molécula de ricina que entra no citosol é capaz de inativar mais de 1500 ribossomos por minuto. Os sinais clínicos associados com a intoxicação de mamona em animais frequentemente ocorrem em algumas horas após a ingestão das sementes. Este trabalho faz uma revisão da literatura sobre os efeitos tóxicos da ricina e as técnicas para a prevenção da intoxicação. Palavras-chave: Ricinus communis, Euforbiacea, toxalbumina, planta tóxica, toxina AbstractThe castor bean (Ricinus communis) is a bush from Euphorbiacea family cultivated for obtaining oil from the seeds. This oil has broad industrial employment, particularly for biodiesel. However, castor bean seeds exhibit a potent toxin, ricin. It is a glycoprotein with highly toxic action of inactivating ribosomes. The toxic action of ricin is due to inhibition of protein synthesis in eukaryotic cells, causing cell death. Only one molecule of ricin that enters the cytosol is able to inactivate ribosomes over 1500 per minute. Clinical signs associated with castor bean poisoning often occur in animals in a few hours after ingestion of the seeds. This paper reviews the literature on the toxic effects of ricin and techniques for preventing the poisoning.
