| Abstract:
The chemical composition of the leaves, the peeled tubers, and the peels of 6 local varieties of cassava was determined in a feeding trial with 300 broilers separated in 6 groups. The nutritional efficiency of 3 diets containing either 0, 5, or 30% cassava root meal in substitution of maize was also compared. Cassava leaves contained, on dry matter basis, 23.3% crude protein (CP), 20.3% crude fiber (CC), and 7.5% crude fat (CF). The leaf proteins were more concentrated in the blades (28.3%) than in the petioles (8.2%). The peeled tubers and peels contained 4.6 and 10.6% CP, respectively. The level of non-nitrogen extract was 90% for the peeled tuber and 70% for the peels. Using diets with 15 or 30% cassava meal had no detrimental effect on weight gain, feed efficiency, and mortality rate of broilers. However, the economic evaluation showed that the use of cassava in substitution of maize was not economical. | |
