METABOLISABLE ENERGY VALUE AND ANTI-METABOLITES OF CASSAVA PEELS PRODUCTS IN POULTRY

Résumé

The metabolisable energy value and antinutrient composition of cassava peel products were determined in this study. Four cassava peel products namely; coarse cassava peel mash (CCPM), fine cassava peel mash (FCPM), whole cassava peel mash (WCPM) and sundried cassava peel meal (SCPM) were processed from fresh cassava peels. The products were assessed for energy values and antimetabolites. Results showed that CCPM had significantly higher (P<0.05) gross energy (3577.20KKcal/Kg), while FCPM had the highest apparent metabolisable energy (2862.7) Kcal/Kg). The SCPM contained the highest (P<0.05) cyanide, oxalate, tannin, saponin and alkaloids which ranged from 14.52-20.63mg/100g (cyanide), 28.24-68.58mg/100g (Phytate), 6.15-9.13mg/100g (oxalate), 67.79-286.97mg/100g (tannin), 1.21-3.83mg/100g (saponin) and 5.97-10.08mg/100g (alkaloids). It was concluded that processing of cassava peels helped to reduce antinutrient composition of cassava peel products and increased metabolisable energy of cassava peel products.
