ABSTRACT: Distillers dried grains with solubles (DDGS) in
combination with soy protein concentrate (SPC) with and without an essential
amino acid (EAA) complex were assessed as protein alternatives in juvenile
Yellow Perch Perca flavescens diets.
Diets contained 5% FM, 40% SPC, and 20% or 40% DDGS each with or without EAA.
No mortalities or health assessment differences were observed during the trial
and all fish readily accepted the experimental diets. Diets supplemented with
EAA produced greater weight gain, improved feed conversion, and apparent
protein digestibility. Performance was
consistently improved for fish fed diets containing amino acid supplements.
Based on these results, Yellow
Perch are able to utilize high levels of the plant proteins, accompanied with
EAAs, as a FM replacer.
