Abstract
Rumen microorganisms utilize tryptic peptides from Chlorella protein, forming carbon dioxide, volatile fatty acids, and bacterial protein. Peptide carbon is more efficiently converted into bacterial protein than is amino acid carbon. A progressive degradation of the peptides was demonstrated by use of columns of Sephadex G-25.
