【 摘 要 】

Leaves from six varieties of cassava (Manihot esculenta crantz) cultivated in Nigeria were harvested and analysed for their nutritional composition and anti-nutritional factors using standard analytical techniques. The leaves were further processed into cassava leaf protein concentrate. Results obtained indicated highest crude protein levels, β-carotene levels and lipid levels of 48.85 ± 0.45, 816.92 ± 8.80 and 13.27 ± 0.06, respectively, in variety 419 and lowest crude protein levels and β-carotene levels of 40.19 ± 0.08 and 298 ± 5.74 in variety 326. However, ash, moisture and carbohydrate levels for all six varieties were relatively the same. Mineral compositions for all varieties were also fairly similar. Hydrogen cyanide levels were significantly low (p > 0.05) in variety 419 with a value of 0.98 ± 0.05. However, phytate and tannin levels for all six varieties were not significantly different (p > 0.05). It can be concluded from this study that cassava variety 419 had the highest potential for use in aqua feed production.
