Evaluation of a Commercial High-Protein Distiller’s Dried Grain with Solubles (HP-DDGS) Product in the Diet of Juvenile Nile Tilapia (Oreochromis niloticus)

Table 1

Formulation and proximate composition (g kg^-1 dry diet weight) of the control diet and experimental diets containing graded levels of ProCap Gold HP-DDGS ingredient which were fed to Nile tilapia. Diet labels indicate total protein contributed by HP-DDGS in g kg^-1.
