At birth, the rumen is very small, and the fourth stomach (or abomasum) is by far the largest of the compartments. Digestion in the young calf is more like that of a simple-stomached animal than that of a ruminant, and it takes approximately three to four months before the calves can be considered actual ruminants.

Rate of orchardgrass NDF digestion in situ was faster for heifers fed the dextrose than for those fed the medium concentrate diet, ... Total NAN and bacterial N flow to the duodenum and efficiency of bacterial protein synthesis in the rumen were greater with the medium concentrate diet than with the control and dextrose diets.

Procedure: The rumen digestion of chopped hay (poor quality hay from Scotland) was measured using dacron bags (Rodr guez 1968; Mehrez and 0rskov 1977). About 10 g of the hay was weighed into a dacron (parachute material) bag measuring about 8 x 10 cm. The bag was closed and secured by a nylon drawstring.

3. Rumen digestion was observed to come to a standstill within 12 hours after feeding. Prolonging the digestion periods to 24 hours did not increase rumen digestion coefficients. Lignin apparently protects plant fragments from further action by rumen microflora.
