Growth and Development of the Ruminant Gastro-Intestinal Tract Rumen papillae begin growth and development early in gestation. The process begins as a capillary loop at about 3 months of gestation. The capillary loop pushes up the lamina to create the papillae of the ruminal surface which is detectable by the 5 th month of gestation.

Growth and Development of the Ruminant Gastro-Intestinal Tract Individual GI tract organs develop at different rates during gestation Early in gestation the rumen, reticulum and omasum develop faster than the abomasum. Later in gestation the abomasum develops rapidly, so that at birth the abomasum is equal in weight to the entire forestomach.
