“…In rainbow trout, apparent digestibility coefficients (ADCs) of protein (88-90%) and lipids (79-89%) is high, but that of dry matter (47-59%) and energy (50-67%) is much lower, reflecting the high indigestible carbohydrate content of DDGS (Cheng and Hardy, 2004). In hybrid striped bass, however, DDGS protein, lipids and dry matter digestibility are much lower (65%, 69% and 10%, respectively; Thompson et al, 2008). Thus, ADCs of DDGS seem to be dependent on the digestive capacity of the fish species, particularly in which concerns the digestion of non-protein energy fraction that is higher in fish with lower trophic level (Castro et al, 2013).…”

Corn distillers dried grains with solubles (DDGS) is a co-product of corn ethanol production which biological value is dependent on technological processes and so may be highly variable among production plants. Therefore, two digestibility trials were conducted to evaluate the apparent digestibility coefficients (ADCs) of nutrients and energy of two commercial sources of DDGS and their effects on digestive enzyme activities in European seabass and meagre juveniles. DDGS digestibility was determined based on the substitution of 30% of a reference diet (45% CP; 16% CL) by each test DDGS. ADCs of protein (92-98%), most amino acids (75-99%) and lipids (82-89%) were high while that of energy (58-68%) was low, reflecting the high indigestible fiber content of DDGS. ADCs of nutrients and energy of DDGS were similar in both species, except for some amino acids (lysine, arginine, histidine, isoleucine, tyrosine and aspartic acid) which were higher for seabass than for meagre. Independent of fish species, ADCs of protein and energy were higher in DDGS 1 than in DDGS 2 , whereas ADCs of lipids and most amino acid were not affected by DDGS source. Digestive enzymes activities were species specific: protease activity was higher in meagre while lipase and amylase activities were higher in seabass. For both species, all digestive enzymes activities were higher in mid intestine than in anterior or distal intestine. Overall, it is concluded that corn DDGS is well digested and seems to have high potential for inclusion in diets for seabass and meagre juveniles.

“…Since the late 1940s, DDGS has been integrated in fish feed at low inclusion levels (Thompson et al, 2008). In several studies, DDGS has been investigated for species such as Nile tilapia (Wu et al, 1996;Coyle et al, 2004;Lim et al, 2007), channel catfish (Webster et al, 1993;Robinson and Li, 2008;Lim et al, 2009), and rainbow trout (Cheng and Hardy, 2004) where 20-35%, 30-40%, and 22.5%, respectively, could be included without adverse effects on growth performance and weight gain.…”

Demands for seafood products are steadily increasing. Alternative protein sources are required to compensate for enormous amounts of fishmeal that is needed for global seafood production. Starch is a food polymer that can be added to fish feed formulations to enhance binding and expanding capabilities of extrudates. Floatability, a key factor for most aqua feeds, can be optimized by the addition of certain starch sources. Six ingredient blends with a similar protein content (~32.5%) containing two starch sources, Hylon VII (containing 70% amylose, 30% amylopectin) or Waxy I (containing 0% amylose, 100% amylopectin), 20% distillers dried grain with solubles (DDGS), and 15, 25, and 35% moisture content were used along with appropriate amounts of soybean meal, menhaden fishmeal, whey, vitamin and mineral mix to investigate nutritionally-balanced feeds for Nile tilapia (Oreochromis niloticus L.). The blends were processed using a laboratory single-screw extruder with varying temperature settings (90-90-90°C, 100-120-120°C, and 100-120-140°C), screw speeds (100, 120, and 140 rpm), and length/diameter ratio (3.4, 6.6, 9.2) of the die. Extensive analyses of expansion ratio (ER), unit density (UD), sinking velocity (SV), and pellet durability indices (PDI), water absorption (WAI) and water solubility indices (WSI) were conducted to evaluate the effects of the two starch sources on extrudate binding and floating capacity. By varying process conditions, significant differences (P>0.05) among the blends were detected for all extrudate physical properties. Significantly higher values for ER, UD, and PDI were achieved by using the Waxy I starch source, while values for SV and WAI decreased. For WSI no significant differences were detected. Increasing the moisture content from 15-35% resulted in a significant increase in ER, WAI, and PDI and a significant decrease in UD. WSI showed no clear pattern in changes. The impact of different amylopectin to amylose ratio, temperature and moisture content on extrudate stability, cohesion and physical properties was demonstrated in this study. All formulations yielded viable extrudates while the blends with the amylopectin as the sole source of starch resulted in higher quality extrudates.

“…Any excess is considered biologically as well as economically wasteful (Erfanullah, 1995). Soybean meal (SBM) is one of the most studied and widely used as plant protein sources in commercial aquatic feeds for many species, such as tilapia, hybrid striped bass, rainbow trout, Atlantic salmon (Salmo salar) and hybrid sunshi bass (Morone chrysops × M. saxatilis) (Steffens, 1994;Thompson et al, 2008;Furuya et al, 2004;Rawles et al, 2009). Distillers dried grains with soluble (DDGS) is another ingredient.…”

This work was conducted in the regional laboratory for food and feed, Agriculture Research Center, Giza, Egypt, in a closed recirculation water system for 12 weeks to determine the effect of replacing 0, 10, 20, 30 and 40% soybean meal and yellow corn in tilapia (Oreochromis niloticus) diets by Distillers Dried Grains (DDGS) with and without enzyme (Ameco Zyme 2x, 0.25g/kg). Therefore, nine isonitrogenous (30% CP) and isocaloric (3200 kcal GE/kg) experimental diets were formulated, D1, repsant the (control). In the other experimental diets, soybean meal and yellow corn mixture was replaced with DDGS at a rate of 10% (D2), 20% (D3), 30% (D4), 40% (D5), 10% DDGS+ Enzyme (D6), 20% DDGS+Enzyme (D7), 30% DDGS+ Enzyme (D8) and 40% DDGS+ Enzyme (D9). A total number of 405 tilapia fry (0.98 g±0.01) were randomly distributed into 27 tanks (60 liters each) at a stocking rate of 15 fry/tank. After 84 days from the experiment start no significant differences (P<0.05) were observed in survival rate, the highest specific growth rate (3.5 %/day) was recorded for fish feed D7, while fish fed D5 showed the lowest value (2.83 %/ day). The best feed conversion ratio (FCR) was occurred when fish fed D6 or D7 while the worst value was recorded by fish group fed D5. Protein efficiency ratios (PER) were found to be high when fish were fed diets containing enzyme. Body crude protein content for fish fed D1, D2, D6 or D7 were significantly higher than the other diets while fish group fed D5 showed the highest significant (P<0.05) body fat content compared to fish fed the other diets. The obtained results refers to the possibilities of replacing soybean meal and yellow corn mixture in the control diets with DDGS up to 20% without enzyme and up to 30% with enzyme addition.
