The replacement value of a by-product of cassava harvesting - cassava fruit coat (CFC) meal - for wheat bran for broiler production was investigated. CFC was produced by milling dried cassava fruits often discarded after harvesting the roots and stems. The CFC meal was used to replace 25, 50, 75 and 100% wheat bran (w/w) in a basal diet for broilers. Seventy-five one-week old broiler chicks were distributed into 15 pens each holding 5 birds. Each of the 5 experimental diets was allocated at random to 3 pens. At the end of the first 4 weeks (starter phase), the diets were switched to finisher diets for a further 4-week period. Feed and water were supplied ad libitum. Data were recorded and analysed on pen basis. CFC meal had a crude protein of 44 g/kg and crude fibre of 149 g/kg.
All production parameters, other than mortality, deteriorated as the degreed of substitution of wheat bran by CFC was increased. The apparent digestibilities of dry matter and nutrients were significantly (p<0.05) reduced by dietary increase in level of CFC.
It is concluded that CFC can replace up to 50% of the wheat bran requirement for feeding broilers in the finisher phase, but higher levels markedly reduce performance.
