Coprophagy in marmosets due to insufficient protein (amino acid) intake

Abstract

In the course of experiments to study the minimal protein requirement of common marmosets by nitrogen balance methods, coprophagy was observed. It occurred in most animals fed diets either with a protein content below 6% or lacking histidine/arginine. The protein level of 6% had previously been evaluated as being the minimal protein requirement for maintenance of marmosets. © 1988, Royal Society of Medicine Press. All rights reserved.
