Abstract

An in vitro and in situ study was conducted to assess the effects of donor diet at time of incubation on NDF digestibility of corn residue samples. Residue samples had greater NDF digestibility when animals were on a similar diet (i.e. a high corn residue diet). Digestibility of NDF was greater when time of incubation increased. Th e diet of the donor steer had greater impact as time of incubation increased implying that the animal’s diet, and incubation time, has an impact on the true values of NDF digestibility.
