Inclusion of Distillers Dried Grain as Partial Replacement of Wheat Flour and Soybean Meal in the Diet of Juvenile Abalone Haliotis discus hannai

Abstract

An 8-week feeding experiment was conducted to determine the influence of dietary distillers dried grain (DDG) on the growth and body composition of juvenile abalone Haliotis discus hannai. Five diets were formulated to contain 0% (DDG0), 15% (DDG15), 30% (DDG30), 45% (DDG45), and 60% (DDG60) DDG, and three replicate groups of abalone (average body weight: 3.6 ± 0.21 g) were fed one of the experimental diets at a feeding rate of 5% body weight per day once daily (17:00 h) for 8 weeks. Survival, shell length, and shell width of juvenile abalone were not affected by dietary DDG levels (P > 0.05). Weight gains of juvenile abalone fed DDG15 and DDG30 diets were not different compared to DDG0, but abalone fed DDG45 and DDG60 diets gained less weight than those fed DDG0 (P < 0.05). Soft body weight/body weight ratio of juvenile abalone fed the DDG60 diet was lower than that of those fed the DDG0 diet (P < 0.05), but proximate composition of the soft body was not affected by dietary DDG levels (P > 0.05). The results of this experiment suggest that DDG is a good replacement for wheat flour and soybean meal, and can be used up to 30% in the diet to maintain the growth performance of the juvenile abalone.

Distillers dried grain can be used as a feed ingredient for the growth of freshwater snail (Semisulcospira coreana) and abalone (Haliotis discus hannai)

“…Schaeffer, Brown and Rosentrater (2011) reported that 20% of the corn-based DDG can be used in the diet for yellow perch without hampering the growth performance. The nutrient composition of wheat flour and soybean meal used in the present experiment was consistent with previous reports (Choi et al , 2014a. Crude protein, lipid and ash contents of DDG used in the previous study (Choi et al 2014a) were 215, 45 and 9 g kg À1 respectively.…”

The different nutrient values of DDG used among studies may be because of different DDG materials and fermentation processing methods.…”

“…Information on the nutritional values of rice‐based DDG for shellfish is limited. Rice‐based DDG could be an economical ingredient for juvenile abalone, Haliotis discus hannai (Choi, Rahman & Lee ). Previous studies indicated that the dietary inclusion of DDG from rice improved the growth performance of sea cucumber (Seo, Shin & Lee ; Choi, Rahman & Lee ).…”
