Use
Inclusion limit
Ruminants: replacing cereals up to 30-40% gave satisfactory performance; beef cattle pellets up to 65% of DM when carefully balanced [E-S7]. Pigs: up to 60% in growing-finishing pigs [E-S7]. Broilers: high-grade pelleted cassava limited to 30-40% by its low protein; in meal form not above 20-30%, especially young birds; lower-grade cassava not above 20-30% [E-S7]. Layers: up to 50% did not significantly reduce production when HCN is low and diet balanced [E-S7].
HCN: bitter varieties 0.02-0.03% HCN in root DM; roots with <0.01% (100 mg/kg) HCN in DM are generally considered safe; drying or ensiling detoxifies [E-S7]. Low protein; extra sulphur amino acids (methionine, cystine) needed because they are used in HCN metabolism [E-S7]. Low carotenoids: add pigments for yolk colour [E-S7]. Rapid rumen starch degradation: split feeding helps [E-S7]. Dusty, unpeeled or high-HCN product has lower value [E-S7].
