Inclusion limit
Broilers: 4% and 8% did not significantly reduce performance, 12% and 16% depressed it (Khempaka et al. 2009, cited in E-S6). Layers: 10% pomace reduced intake and performance in one trial [E-S6]. Pigs: detrimental at 7-10% in some trials, 15% not detrimental to piglets; 30% dried starch residue in gestating sows [E-S6]. Sheep and goats: pulp replaced cassava peels at 15% and 30% without harming growth [E-S6].
Cyanogenic glucosides (linamarin, lotaustralin) release HCN; pulp contains less than peels; drying or ensiling used [E-S6]. Very low protein (1-4% DM); starch 15-50% DM and NDF >35% DM vary with extraction technology [E-S6]. Fresh pulp is mostly water (see E-S6 fresh table, BK 13.1%) and spoils unless dried or ensiled [E-S6].
