TI - Comparative evaluation of non-toxic and toxic varieties of Jatropha curcas for chemical composition, digestibility, protein degradability and toxic factors N2 - Four varieties of Jatropha curcas which originated from Nicaragua (Cape Verde and Nicaragua toxic varieties cultivated in Managua), Nigeria (a wild variety from Ife; toxicity unknown)and Mexico (a wild non-toxic variety collected from Papantla)were studied. The average seed weight was 0.69, 0.86, 0.53 and 0.65g for Cape Verde, Nicaragua, Ife-Nigeria and non-toxic Mexico varieties, respectively. The kernel to shell ratio in seeds was relatively similar (62.7:37.3 for both Cape Verde and Nicaraguan, 60:40 for Ife-Nigerian and 63.5:36.5 for non-toxic Mexican). The shell of the seeds composed mainly of fiber (>83 UR - https://drive.google.com/file/d/1--kVTNlgY4Aa47tbhs-zyFT0kDEk9y78/view?usp=drivesdk ER -
