“…Contrary to the findings of Heikkinen et al (2006), a more recent study by Merrifield et al (2009), did not reveal any differences in the in total culturable aerobic levels when comparing the autochthonous and allochthonous gut populations of rainbow trout fed a FM control diet with those fed a SBM diet (SBM inclusion at 32%) for 16 weeks. Figure 6).…”

“…In many of these other studies, fish meal-based control diets were not used, or the concentrations of other non-soy protein sources were altered in the experimental diets [14][15][16]24,[48][49][50][51][52][53]. However, Barrows et al [54] suggested that soybean meal replacement for fish meal should be limited to less than 25% (or 10% to 15% dietary inclusion rates).…”

“…Inclusion rates for soybean meal in salmonid diets have typically been low because of the presence of trypsin inhibitors, lectins, saponins, poorly digestible carbohydrates (oligo-and polysaccharides), and other anti-nutritional factors [9][10][11][12]. Soybean meal in rainbow trout diets produces welldocumented deleterious effects on the distal intestine, such as morphological changes and subacute enteritis [12][13][14][15][16][17][18][19], as well as changes to intestinal microbial communities [15,16,18], and hepatic morphology [12]. Similar effects have been reported in Atlantic salmon Salmo salar [20][21][22][23].…”

The inclusion of PepSoyGen (PSG), a commercially-available fermented soybean meal product, was evaluated with juvenile rainbow trout, Oncorhynchus mykiss in an initial 70-day feeding trial, with a supplemental trial involving a subset of the experimental diets continuing for an additional 40 d. Six diets containing 0%, 10%, 20%, 30%, 40%, or 50% PSG, with the PSG directly replacing fish meal, were used in the first trial. There were no significant differences in weight gain or feed conversion ratio between the fish meal-based control diet and diets containing up to 30% PSG. However, weight gain was significantly reduced and feed conversion ratio significantly increased with the 40% and 50% PSG diets. No health assessment differences were observed in fish receiving any of the diets, and no evidence of gross gut inflammation was evident. There were no significant differences in weight gain or feed conversion ratio among the four dietary treatments ranging from 0% to 30% PSG which were fed for an additional 40 d after the initial 70-d trial (110 days total). Based on these results, juvenile rainbow trout diets can contain up to 30% PSG without any loss of rearing performance, thereby replacing at least 60% of the fish meal.

“…In several aquatic species replacement of FM with vegetable protein sources such as SBM resulted in lower weight gain (Francis et al 2001) and histopathological damages (Aslaksen et al 2007;Kraugerud et al 2007;Krogdahl et al 2003), the magnitude of which depends on the source and level of replacement (Merrifield and Olsen 2011). Thus, the change from FM to soybean meal generally causes several metabolic and health challenges for the farmed aquatics (Heikkinen et al 2006). Hence, when using plant derived materials, especially those from soybean at high replacement levels it is necessary to consider the impacts on intestine histology as the gastrointestinal (GI) tract can be one of the important infection routes for some pathogens in fish (Merrifield and Olsen 2011;Gatlin et al 2007).…”

Effect of dietary soybean meal and multienzyme on intestine histology of beluga sturgeon (Huso huso)

This study aimed to evaluate the effect of soybean meal and multienzyme supplementation on intestinal histopathology of beluga sturgeon (Huso huso). Nine diets were formulated (40% crude protein, 13% crude fat and 4150 kcal/kg gross energy) in which fish meal was replaced by soybean meal at 0, 40 and 80% supplemented or not with 1 or 2 g/kg of multienzyme Kemin. Fish (initial weight of 820 g) were fed on experimental diets four times daily at 1% body weight for 12 weeks. From histological analyses, intact villus with normal mucosa was found in the FM group, representing the presence of intact epithelium. Supplementation of enzyme at both levels and soybean meal (alone) in the diet resulted in histopathological alterations in the intestine including mild immune cells infiltration, villus blunting, villus fusion, mononuclear immune cells infiltration as well as necrosis. Soybean meal decreased the length of villuses in the proximal and distal intestines (P \ 0.05). Enzyme was not able to ameliorate the derangements induced by 80% replacement level of fish meal with soybean meal (treatments SB80E1% and SB80E2%). However, coadministrating of the enzyme at both levels with 40% soybean meal (treatments SB40E1% and SB40E2%) was able to inhibit the soybean meal-induced histopathological impairments.
