Physical constraints on voluntary intake of forages by ruminants

MS Allen - Journal of animal science, 1996 - academic.oup.com
Voluntary dry matter intake (VDMI) of forages by ruminants may be limited by distention
resulting from restricted flow of digesta through the gastrointestinal tract. An animal's …
