Single Cell Protein in the Diets of Pigs and Chickens

Effects on the Activity of Dnase in Intestinal Contents

Abstract

Pigs and chickens were fed diets containing increased concentrations of the single cell protein (SCP), Pruteen, in order to investigate the effects of a diet containing high levels of nucleic acids on the activity of DNase in intestinal contents. Increased levels of SCP in the diet generally resulted in increased DNase activity in intestinal contents.

Significant differences at P0.05, were found between the control groups and most of the experimental groups in both species.

With the exception of the 2 groups given the highest levels of SCP in the chicken experiment, the DNases in the large intestines were not inhibited by antisera produced against DNase in pancreatic juice.
