“…The inclusion of the treated JSC on diets for goats at a rate up to 20% of incorporation for a period of 72 days showed no effects on animal performance parameters as well as on measured hematological and clinical chemistry parameters. On the other hand, studies reported by Okukpe et al [95] showed that goats fed on diets with the inclusion of JSC treated with T. ghanense and T. asperellum, at up to 4% of the total diet, were severely affected as determined by the measured parameters for animal growth and high mortality levels after five weeks of trial. It should be noted that no data are presented for the phorbol ester concentrations of the treated JSC.…”

Jatropha seed cake (JSC) derived from Jatropha curcas seeds is a by-product of biodiesel production and, due to its high protein content, has been considered as a potential animal feed ingredient. However, the presence of toxic compounds such as phorbol esters and other anti-nutritional factors limits its use in animal feeding. Several detoxification approaches have been used to tackle these constraints and this review aims to summarize the recent advances in JSC treatment aiming to enhance its potential as an animal feedstuff. The review first provides an overview of the structure and composition of phorbol esters and other anti-nutritional compounds, discussing its toxic effects on different animal species. It then explores several detoxification methodologies giving special emphasis to its effects on the nutritional composition of JSC and on the use of the treated substrate as a feed ingredient in fish, poultry, pigs, and ruminants, highlighting their growth performance, nutrient utilization, and animal health issues. Overall, the review concludes that these treatments hold great potential for the detoxification and utilization of JSC as an animal feed ingredient. However, further research is needed to optimize the treatment conditions, evaluate the economic feasibility, and assess the long-term effects of treated JSC on animal health and product quality.

“…In addition, the effect of sunlight exposure (solar radiation) at different durations of up to 72 h was explored, and achieved a reduction in Jatropha PEs of 77.9%. In addition to the above studies, treatments for Jatropha seed cake have also been applied in studies by Chandrasekar et al (2009) and Okukpe et al (2012), where feeding studies have also been performed. However, as PE concentrations before and/or after treatment are not given, the treatment details have not been included in this section.…”

Risks for human and animal health related to the presence of phorbol esters in Jatropha kernel meal

Following a request from the European Commission, the risks for human and animal health related to the presence of phorbol esters (PEs) in Jatropha kernel meal were assessed by the EFSA Panel of Contaminants in the Food Chain (CONTAM). Jatropha curcas (Jatropha) seeds contain substantial amounts of extractable oil utilised for biodiesel production. The remaining protein‐rich products (seed meal or kernel meal) may be used as a protein source in animal feed after removal of anti‐nutritive factors and toxic PEs. The available data on absorption of Jatropha PEs after oral ingestion, biotransformation, elimination, and dose‐dependent toxic effects are very limited, and only for pigs a no observed adverse effect level (NOAEL) of 0.4 mg PEs/kg bw per day (12‐O‐tetradecanoylphorbol‐13‐acetate (TPA) equivalent), based on decreases in body weight gain and feed intake, could be identified from short‐term feeding studies. No health based guidance value for humans could be established. Processes that almost completely remove or degrade toxic PEs in Jatropha products are available, resulting in levels below the limit of detection of 3 mg Jatropha PEs/kg (TPA equivalent). Replacement of 50% of the protein in compound feeds with treated Jatropha materials would result in animal exposures that are still 10 to 200‐fold lower than the NOAEL for pigs. The CONTAM Panel concluded that such use of Jatropha material would not pose a health risk to pigs and that the risk to other species is likely to be low. The transfer of Jatropha PEs to animal derived products is unknown. In a human exposure scenario using a 50% transfer rate from feed to milk, a daily intake of 1 μg Jatropa PEs/kg bw per day was calculated. The CONTAM Panel concluded that more data are needed to draw firm conclusions on human risks.

“…The WAD Does fed T4RRP utilized the crop by-product for body weight gain poorly when compared with other dietary groups. The poor intake may be due to heavy metals (lead and cadmium) and some anti-nutritional factors (Adeniji et al, 2008;Okukpe et al, 2012). This may have caused poor intake and a resultant reduction in weight.…”

This study was conducted to investigate the performance and haemato-biochemical parameters of WAD Does fed crop by-products: Yam peels(T1YP) Cassava peels (T2CP), Sweet potato peels (T3SPP) and Ripe plantain peels (T4RRP) in humid tropical Cross Rivers State of Nigeria. Sixteen (16) Consequently, the utilization of crop by-products used in this study has no deleterious effects on the nutritional and health conditions of the WAD Does and is recommended for use in goat production systems.
