According to research conducted by the FAO, non-toxic Jatropha kernel meal could be an alternative source of protein for aqua feed and animal feeds. Below is a summary of the findings and a link to the full report.
Harinder Makkar, livestock production officer at the FAO has been looking into the possibilities of using non-toxic Jatropha kernel meal in animal and fish diets. The animal feed industry is growing at a rapid pace, and production is switching to intensively managed high-input systems. The main input in any livestock production system is feed, and demand for feed for aquatic organisms is expected to nearly triple by the end of the decade.
Jatropha kernel meal as a protein source in aqua feed
Aquaculture continues to grow at a faster pace than the farming of terrestrial animals. For fish and shrimp feeds, the most pressing need is to find alternative protein sources. Several studies performed on partial replacement of protein sources, especially fishmeal, by detoxified J. curcas kernel meal (DJKM), heated J. platyphyllakernel meal (H-JPKM) and detoxified jatropha protein isolate (DJPI) in fish and shrimp diets are presented in the study.
Using detoxified Jatropha in poultry feed
Soybean and canola meals (i.e. rapeseed meal) are the major protein meals used worldwide in poultry feed (USDA, 2010). However, SBM competes with human food and there is a need to search for alternative plant-protein sources for poultry feed.
Research carried out on 3-week-old turkeys showed that detoxified Jatropha kernel meal was a valuable protein source.
Jatropha kernel meal in pig feed
The most commonly used source of supplemental protein in diets for non-ruminants is (soybean meal) SBM because of its excellent amino acid profile and dependable supply. In a typical pig diet, soybean supplies about 50% of the protein and amino acids and about 25% of the metabolizable energy. Wang et al. (2011) investigated the effects of replacing SBM by detoxified J. curcas kernel meal (DJKM) in the diet of the growing pig. The result showed that incorporating detoxified Jatropha kernel meal had no ill effects on health and could replace 50% soymeal protein in diets of growing pigs.
