“…Concomitant dietary lysine supplementation may enable DDGS incorporation up to 60% without affecting growth performance, immune function or disease resistance of Nile tilapia (Shelby et al, 2008). Similarly, in channel catfish, DDGS can be included in the diets up to 40% (Tidwell et al, 1990) or to 70% if diets are supplemented with lysine (Webster et al, 1991) without compromising growth performance and feed utilization. Moreover, in channel catfish diets with 90% DDGS without lysine supplementation can be used during winter feeding without affecting performance .…”

Corn distiller's dried grains with solubles: Apparent digestibility and digestive enzymes activities in European seabass (Dicentrarchus labrax) and meagre (Argyrosomus regius)

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.

“…Yet another study evaluated the growth response of channel catfish fed a diet containing 30% DDGS, and no ill effect was observed (Tidwell et al, 1990). Fish meal replacement with 70% DDGS and 4% lysine supplementation in channel catfish diet was studied and relatively similar results were observed (Lim et al, 2009;Webster, 1991;Zhou et al, 2010). Robinson and Li (2008) studied the effect of replacing fish meal with several plant-based protein for channel catfish and suggested that at least 30% DDGS can be used in the diet when lysine is supplemented.…”

Twin-screw extrusion cooking trials were performed to investigate the differential effects of conventional DDGS (DDGS) and HP-DDG inclusion, as fishmeal replacers, on physical properties (moisture content, water activity, thermal properties, expansion ratio, unit density, bulk density, water absorption, solubility and pellet durability indices, and color) of Rainbow trout (Oncorhynchus mykiss) feed. Four ingredient blends were formulated with 20 and 40% C-DDGS, and 20 and 40% HP-DDG, along with other required dietary ingredients. Each diet was extruded using two replications; a fishmeal based diet acted as the control diet. The highest and the lowest extrudate moisture content and water activity were observed for the diets containing 20% DDGS and 40% HP-DDG, respectively. Compared to the control diet, increasing HP-DDG content from 20 to 40% had no effect on the bulk density of the products, while increasing DDGS content from 20-40% led to a considerable rise in bulk density of the extrudates by 14.2 and 6%, respectively. Also, extrudates with the lowest brightness, greenness, and yellowness values were obtained from the diet containing 20% DDGS, whereas the most color intensity values were observed for the diets containing 40% DDGS and 20% HP-DDG. Increasing DDGS and HP-DDG from 0-40% caused a remarkable increase in water absorption index, by 72 and 30%, respectively. Likewise, the water solubility index increased, but in a considerably lesser order of magnitude. High pellet durability index of more than 99% was achieved with inclusion of either DDGS or HP-DDG. None of the diets impacted the thermal properties of the extrudates. Inclusion of 20 and 40% DDGS resulted in the extrudates with the largest and the smallest unit density values of nearly 887 and 750 kg/m 3 , respectively. As was expected, expansion ratio decreased with increasing unit density. Increasing inclusion levels of HP-DDG did not show any effect on unit density or expansion ratio of the products. Future research should concentrate on investigating the effects of both extrusion processing and graded levels of different types of DDGS on Rainbow trout feeds.

“…[15][16][17] In the present studies, MPF was found to be able to replace, without any additional treatment, 40% of the WFM protein in the diet for fingerling rainbow trout without any adverse effect on growth, feed efficiency, and protein and energy retention. This may suggest that, like DGS, MPF does not contain an appreciable quantity of antinutritional factors.…”

“…16,17) This may be caused by the improvement of amino acid balance and subsequently enhanced conversion of amino acids absorbed into the fish's body protein. 20) MPF, like DGS, is deficient in lysine compared with WFM or SBM (Table 4).…”

Two feeding experiments were conducted to evaluate malt protein flour (MPF) as an alternative protein source for the diet of rainbow trout Oncorhynchus mykiss fingerlings. MPF is a new protein rich by-product from brewer's spent grain. Experiment 1 was conducted to clarify the suitable substitution level of MPF for white fish meal (WFM) in the diet. The control diet, containing WFM as the sole protein source, and isonitrogenous (40% crude protein) experimental diets, containing MPF substituted for 20 to 80% of WFM protein, were fed to fish with an average initial weight of lOg for 6 weeks. Weight gain and feed efficiency in fish fed the diet substituting MPF up to the 60% level were not different (p>0.05) from those in fish fed the control diet. There were no significant differences in protein and energy retention between 0 to 40% substitution level. In Experiment 2, crystalline essential amino acids (EAA) were supplemented in the diets containing MPF to simulate the EAA composition in the control diet. Consequently, no significant differences were detected in protein and energy retention between 0 to 60% substitution level. Thus, these results suggest that MPF is a promising alternative protein source for the diet of fingerling rainbow trout.
