Protein utilization in the ruminant

Abstract

This research has led to a much closer look at the site of digestion, as well as factors involved in nitrogen or protein utilization at the various sites. Many excellent review articles have been written concerning nitrogen utilization which include, Protein requirements for cattle, Symposium (1), Alternate nitrogen sources for ruminants, (2), Urea and other nonprotein nitrogen compounds in animal nutrition (3), and, Progress in the utilization of urea as a protein replacer for ruminants (4), which the reader may refer to for more details. The purpose of this paper is to summarize some of the present research and thoughts on nitrogen utilization in the ruminant.
