Consequently, reduced
MRTs associated with increasing DMIs can impose an intrinsic limit on
the amount of feed the animal can ingest, thus limiting digestible dry
matter intake (DDMI, g kg−0.75 d−1). For example, Clauss et al. (2007b)
found a particularly steep negative relationship between MRT and DMI
in ruminant (sheep and cattle) and non-ruminant (hippopotamus)
foregut fermenters, which truncated their DDMIs at increasing levels
DMI.
