Biofuel co-products as livestock feed - Opportunities and challenges

Use of detoxified jatropha kernel meal and protein isolate in diets of farm animals 373level of 1.5 percent of the DJKM, H-JPKM and DJPI (w/w)inclusion in the diet to compensate for the deficiency. DJKM and H-JPKM contain approximately 9–10 percentphytate, which is almost 3-fold that in SBM. To mitigateits effect, add 1500 FTU phytase per kg of diet (Kumaret al., 2011f). Detoxified jatropha kernel meal-, H-JPKM- and DJPIbaseddiets could be fed to fish at 5 times maintenancerequirements. Single maintenance requirement equals3.2 g feed/kg metabolic body mass (kg 0.8 ) per day.Shrimp (juveniles, >10 g) should be fed 3-4 percent ofthe total body weight per day.POTENTIAL CHALLENGES IN USING DETOXIFIEDKERNEL MEAL AND DETOXIFIED PROTEINISOLATE FROM JATROPHA CURCAS IN FEEDS Inadequately heated jatropha kernel meal that containssignificant amounts of trypsin inhibitor and lectin couldreduce the performance of monogastric animals. Similarly,inadequately detoxified material containing phorbolesters could cause adverse effects. Phorbol esters mustbe below the detectable limit (
