Goats can be picky eaters, and they may not immediately accept new feeds. Any feed changes should be made gradually to avoid upsetting the rumen microbes. Feeding very high levels of grain can also upset the rumen. Grain should never be more than 50% of the total diet, except for heavily-producing dairy goats.
Glossary of Medieval Art and Architecture. groin vault: A vault produced by the intersection at right angles of two barrel (tunnel) vaults. Sometimes the arches of groin vaults may be pointed instead of round. See also: barrel vault.
As the cranial vault is essentially a closed, fixed bony box, its volume is constant. This volume is described by the Monro-Kellie doctrine, proposed in the early part of the 19th century: v.intracranial (constant) = v.brain + v.CSF + v.blood + v.mass lesion. As all these components are fluids, and non-compressible, once the cranial vault is filled, it's pressure rises dramatically.
