“…Values of 81and 90% have been reported earlier for channel catfish (Cruz, 1975) and hybrid tilapia (Hanley, 1987). The present results suggest that soybean meal does not affect lipid digestibility in the species tested, except at the highest level of inclusion in L. fimbriatus, this being in accordance with certain earlier studies with other species (Refstie et al, 2000;Venou et al, 2006).…”

This study was conducted in indoor, aerated plastic tubs to estimate the digestibility of dry matter and nutrients by the carps, Labeo fimbriatus (Bloch, 1795) and Cyprinus carpio Linnaeus, 1758, from three feed ingredients viz., azolla, soybean meal and silkworm pupa incorporated at levels ranging from 0-40% in a diet comprising equal amounts of rice bran and groundnut oil cake using crude fibre as the marker. Activity of the major digestive enzymes was also estimated in the gut of fish at the end of the experimental trial. Utilisation of azolla protein was comparable with that of control diet up to 20% incorporation in both L. fimbriatus and common carp. Major nutrients from soybean were better utilised up to 40% incorporation by the two species. Protein digestibility from silkworm pupae increased at 20% incorporation and decreased at 40% in L. fimbriatus, while fat and nitrogen-free extract digestibility was higher at 20-40% incorporation. In common carp, higher digestibility of protein and fat was recorded at 10-30% inclusion levels of silkworm pupa.

“…Furthermore, in the present study, plasma cholesterol and triglyceride levels have decreasing trend among the dietary treatments. In other studies, same decreasing trend of cholesterol was found in rainbow trout, Oncorhynchus mykiss (Kaushik et al 1995) and gilthead sea bream, Sparus aurata (Venou et al 2006) due to inclusion of SBM in the diet. This might have happened because of the hypocholesterolemic effect of SBM (Davis and Morris 1997;Yue et al 2012).…”

Different levels of dietary soybean meal (SBM) as a fish meal (FM) replacer, with and without amino acid supplementation, for whiteleg shrimp, Litopenaeus vannamei reared in the biofloc system was examined in eight weeks of feeding trial. Eight experimental diets consisted of a basal diet with 0% FM replacement by SBM provided in clear sea water without biofloc system (S 0 SW), four diets replacing FM at 0% (S 0 ), 33% (S 33 ), 67% (S 67 ) and 100% (S 100 ) by SBM, and three diets replacing FM at 33% (S 33 A), 67% (S 67 A) and 100% (S 100 A) by SBM supplemented with amino acids (methionine and lysine) in the seawater biofloc system. Results of water quality analyses showed significantly lower total suspended solids and nitrate for S 0 SW group than all other treatments. Diets S 0 and S 33 A resulted in higher weight gain and specific growth rate among all groups, with no significant differences with S 33 group. In addition, whole-body protein and amino acid compositions of shrimp fed S 0 SW were lower than most biofloc groups. Haemolymph parameters showed significant differences in total protein, cholesterol and triglyceride between groups S 0 and S 0 SW. Also, superoxide dismutase activity showed a decreasing trend with increasing replacement level. In conclusion, based on these results, SBM could replace up to 33% of FM with or without amino acid supplementation in juvenile whiteleg shrimp diets reared in the biofloc system.

“…These findings are in agreement with digestibility studies for a range of species: silver perch (Allan and Booth 2004), yellowtail (Tomás et al 2005), juvenile haddock (Kim et al 2007), sharpsnout seabream (Hernández et al 2007), European sea bass (Tibaldi et al 2006) and gilthead sea bream (Venou et al 2006).…”

“…Protein digestibility was not affected by level of SBM in accordance with a number of studies (Tomás et al 2005, Venou et al 2006, Kim et al 2007) for different fish species. This could be attributed to the generally low valEffect of soybean meal on dentex nutrition 23…”

“…Tomás et al (2005) and Venou et al (2006) reported increased consumption with increasing SBM inclusion in their study (0%-50% SBM). The increase in feed consumption could result from reduced available energy content as SBM inclusion increased, but calculation of the digestible energy content of the diets indicated similar with SBM inclusion (Table 1).…”

Tomás A., Martínez-Llorens S., Jover M. 2009. The effect of dietary soybean meal on growth, nutrient utilization efficiency, and digestibility of juvenile common dentex, Dentex dentex (Actinopterygii: Perciformes: Sparidae). Acta Ichthyol. Piscat. 39 (1): 19-25.Background. The aim of this work was to study the growth of juvenile dentex fed on cooking-extruded diets, determine the level of substitution of fishmeal by soybean meal may be without affecting the growth in this species and its digestibility. Materials and Methods. The availability of defatted soybean meal as a substitute for fish meal was evaluated in juvenile (41 g on average) dentex by feeding diets containing 0%-60% soybean meal, for 97 days.Results. Survival at the end of the experiment was high (80%) except for the fish fed diets with 50% and 60% substitution. Growth, feed gain ratio, and protein efficiency ratio (PER) were slightly reduced at higher soybean meal levels. Fish fed diets containing 0% to 40% of soybean meal grew significantly more and FCR was lower than fish fed other diets. No differences were obtained for protein digestibility coefficients of experimental diets (20%, 30%, 40%, and 50% SBM). Conclusion.The results confirm the best protein level for optimum growth seems to be around 50% and 12% lipid level, and maximum soybean meal substitution of 40%.
