In situ forage protein degradability characteristics in ruminants Von Keyserlingk, Marina A. G.

Abstract

Factors characterizing degradation of feedstuffs in the rumen and intestine are critical components of modem ration formulation equations. This study was undertaken to determine the in situ degradability characteristics of forages commonly fed to lactating dairy cattle. In Experiment 1, dry matter (DM) and crude protein (CP) degradation characteristics of 12 corn silages and 22 grass silages were evaluated using both the rumen and mobile nylon bag in situ techniques. In Experiment 2, 16 alfalfa hays and 14 grass hays were evaluated using the same procedures. Significant (P
