Replacement of Corn for Cassava Meal (Manihot esculenta, Crantz) in the Holstein Calves Diets: 2. Digestibility and Energy Value

[摘要] - Twenty Holstein intact calves, averaging 160 days old and initial live weight of 163 kg, were assigned to a completely randomized design to evaluate the effect of five replacement levels (0, 25, 50, 75 and 100% in dry matter basis) of corn for cassava meal on the intake and apparent digestibility of dry matter, crude protein, neutral detergent fiber, starch and gross energy of the experimental diets. There was no effect of replacement levels of corn for cassava meal on the dry matter intake. The increase of the dietary cassava meal levels linearly increased the apparent digestibility coefficient of dry matter, crude protein, starch, and gross energy, but it did not affect the neutral detergent fiber. The replacement of corn for cassava meal did not affected the dietary energy levels.
