“…The European Food Safety Authority (2008) reports that health risks from consuming milk, meat and eggs from animals fed with castor byproducts are very low. That report quoted the study conducted by Robb et al (1974), who fed cattle for 14 months with diets containing treated castor residue and found no residue accumulation in the muscles, no abnormal effects on the animals and no apparent transfer of ricinine to the milk. Watson (1905) suggests that ricin may be present in the milk of lactating guinea pigs that receive such agglutinins through injection, as the offspring that were fed with such milk became resistant to subsequent injections of the toxin.…”

Twenty-five adult crossbred goats, divided in two groups, were fed over a period of 16 months with diets based on Tifton hay and concentrate feed with (DCM) or without (WDCM) detoxified castor bean meal as a substitute for soybean meal. Throughout 480 days, blood samples were taken to measure lactate dehydrogenase, aspartate aminotransferase, alanine aminotransferase, urea, albumin and creatinine. The animals were euthanized, and the anatomical components (lungs, heart, spleen, liver, kidneys, tongue, empty stomach, empty intestines, omentum, cardiac and renal adipose tissue), carcass and commercial cuts (shoulder, ham, loin, ribs and neck) were weighed. Thereafter, an anatomic dissection of the loin was performed, separating the muscle, adipose and bone tissues. On the muscular part of the loin, longissimus dorsi, the proximate composition, fatty acid profile and the expression of SEW-1, IGF-I and IGF-II were analyzed. A higher incidence of bone tissue was observed in the anatomical dissections of the loin and a lower incidence of fat in the proximate composition of the longissimus dorsi of the DCO group compared to the WDCM group (p < 0.05). The expression of the IGF-II and SEW-1 genes was higher (p < 0.001 for each) in the muscle tissue of the DCM animals. Thus, using detoxified castor bean meal for long periods does not produce significant changes in the anatomical composition of the loin or the proximate composition of the longissimus dorsi. However, the differences in gene expression suggest the need for new investigations and care when using this product for animal feeding.

Aos 480 dias, foram coletadas amostras de sangue para dosagem de lactato desidrogenase, aspartato aminotransferase, alanina aminotransferase, uréia, albumina e creatinina. Em seguida, os animais foram sacrificados e foi realizada a pesagem dos componentes anatômicos (pulmões, coração, baço, fígado, rins, língua, estomago vazio, intestino vazio, omento, tecido adiposo cardíaco e renal), da carcaça e dos cortes comerciais (paleta, pernil, lombo, costelas e pescoço). Posteriormente, foi realizada a dissecção anatômica do lombo, separando tecidos muscular, adiposo e ósseo. Na porção muscular do lombo, Longissimus dorsii, foram analisadas a composição centesimal, o perfil de ácidos graxos e a expressão dos genes SEW-1, IGF-I e IGF-II. Verificou-se uma incidência superior de tecido ósseo na dissecção anatômica do lombo e uma incidência inferior de gordura na composição centesimal do Longissimus dorsii do grupo FMD em relação ao grupo SFMD (p < 0,05). A expressão do gene IGF-II resultou superior (p < 0,001) no tecido muscular dos animais FMD, bem como para o gene SEW-1 (p < 0,001). Diante do exposto, podemos concluir que a utilização do fare...

Detoxification of castor bean residues and the simultaneous production of tannase and phytase by solid-state fermentation using Paecilomyces variotii

In this work, we introduce a biological detoxification method that converts toxic waste from castor beans into animal feed material. This method simultaneously induces the production of tannase and phytase by Paecilomyces variotii; both enzymes have high levels of activity and have the potential to be used in feedstuffs because they decrease overall anti-nutritional factors. The maximum tannase and phytase activities obtained were 2600 and 260 U/g after 48 and 72 h, respectively. SDS-PAGE electrophoresis of the fermented castor cake extracts revealed a reduction in ricin bands during fermentation, and the bands were no longer visible after 48 h. The cytotoxicity of the extracts was evaluated by MTT testing on RAW cells, and a progressive increase in cellular viability was obtained, reaching almost 100% after 72 h of fermentation.

“…Despite the potential of utilization in the feeding of dairy cows (Robb et al, 1974;Matos, 1976), the castor seed meal and cake have been utilized exclusively as organic fertilizers, due to the presence of a powerful toxin (ricin), which reduces the competitiveness in relation to the other oilseeds (Oliveira et al, 2010a;Oliveira et al, 2010b).…”

Productive performance and efficiency of utilization of the diet components in dairy cows fed castor meal treated with calcium oxide

et al. 2012

-The effect of replacing of 0; 0.33; 0.67 and 1.0 (kg/kg) of soybean meal (SBM) by undecorticated castor seed meal treated with calcium oxide (CMT -60 g/kg) was evaluated on performance and efficiency of nutrient utilization in dairy cows. Sixteen Holstein and crossbred cows were distributed in four 4 × 4 latin squares. Animals received concentrated feed at a ratio of 1 kg for 3 kg of milk produced, in the natural matter. The diets had the same amount of nitrogen (150.4 g crude protein/kg DM), containing 325.6 g of concentrated feed/kg DM. There was no effect on the serum concentration of transaminase and the animals showed no clinical symptoms of intoxication by ricin. The intake of DM, crude protein (CP) and non-fibrous carbohydrates (NFC) reduced from 0.67 replacement of SBM by CMT. The intake of neutral detergent fibers corrected for ash and protein (NDFap) increased from 0.33 replacement of SBM with CMT. Although the digestibility of dietary components decreased from 0.33 replacement, the intake of digestible components only reduced from 0.67 replacement. Because of the reduction of digestible energy, the synthesis of microbial CP and the utilization efficiency of rumen-degradable protein for the synthesis of microbial CP reduced with full replacement of SBM by CMT. Milk yield, milk composition, daily variation of body weight and the efficiency of utilization of the nutrients for the synthesis of N in milk reduced from 0.67 replacement of SBM by CMT. Castor seed meal treated with calcium oxide can replace up to 0.33 of SBM (50 g/kg DM diet DM) in the diet of dairy cows with an average milk production of 20 kg/day.
