Abstract
The experiment was carried out to investigate the chemical analysis, fibre fractions and mineral composition of cassava. Detailed chemical analysis of raw cassava root (RCR) and processed cassava root meal (PCRM) was assayed. Results obtained were Subjected to analysis of variance (ANOVA) as applicable to a completely Randomized Design (CRD).Significant means were separated using Duncan’s Multiple Range Test. (RDECRM) had the highest crude protein content (27.10%) while raw cassava root meal had the lowest crude protein content (15.00%). The crude fiber (CF) content of the processed cassava ranged from 83.50% in sun dried, fermented 84.60% to 92.00% in rumen digesta ensiled cassava root meal. Metabolizable energy of processed cassava were significantly different (P=.05). AMEn reduced with the inclusion level from (12.32a -11.11c), all other parameters were not affected. The neutral detergent, acid detergent lignin and cellulose were not significantly influenced (P=.05) by the different processing methods. Acid detergent fibre and hemicellulose of raw and processed cassava were significantly different (P=.05) the values ranged from (15.70 -13.17%) and (10.10 - 8.57%) The rumen digesta ensiled cassava root meal proved to be superior to sun dried and fermented cassava.
