Summary

This study evaluated the suitability of commercially produced fermented soybean meal (FSBM) known as PepSoyGen™, in a plant-based diet for Florida pompano, Trachinotus carolinus fingerlings. An 8-week growth trial was conducted to evaluate the effect of four isonitrogenous and isolipidic diets containing 0, 206, 309 and 410 g/ kg FSBM, replacing approximately 0%, 50%, 75% and 100% SBM (designated as Basal, FSBM 50, FSBM 75 and FSBM 100, respectively) on growth performance, body composition, serum biochemistry and morphological condition of liver and distal intestine of Florida pompano. There were no significant differences in final mean weight, percentage weight gain, thermal unit growth coefficient and feed conversion ratio in all treatments. For serum biochemistry analysis, there were no significant differences in total protein, albumin, glucose, cholesterol, bile acids, plasma alkaline phosphatase, alanine aminotransferase and aspartate aminotransferase activities in all treatments. Cellular infiltration, presence of goblet cells and the width of lamina propria in the distal intestine were partly improved in fish fed FSBM 75 and 100 compared to the fish fed FSBM 50 and basal diet. Glycogen granulation, inflammation and nuclear change condition in the liver of pompano were better as the inclusion of fermented product increased. Results of this study indicate that FSBM can be utilized as an alternative protein source and microbial fermentation process could improve the functional properties of SBM.

Key Words: fermented soybean meal, growth performance, histology, serum biochemistry, Trachinotus carolinus.

Incorporation up to 25-30% is fine

Say we are in the field of supplying feed supplement. We can give in one product macro and micronutrients with probiotics and a good amount of organic carbon.

This is yeast base fermentation with good results. Maintains integrity of the digestive system with good FCR.

Do you have any recommendation maximum level of SBM on feed? If any different between fresh water, marine fish, and shrimp.

Soybean meal (SBM) after fishmeal the most expensive ingredient in the fish feed. Furthermore, the anti-nutritional factors present in SBM such as lectins, protease inhibitors, antigenic compounds and so on tend to reduce the fish’s growth and effect of pathological changes on its intestinal mucosa. Once the SBM level exceeded 50% in the feed, this induces mucous membrane inflammation and damages the intestinal mucous membrane. So, it is very necessary to find other plant protein sources to partially or totally replace SBM to solve this problem. Fermented soybean meal to replace soybean is a good idea however, the overall incorporation level in the feed also should be checked thoroughly.

Do we know the FCRs when compared with a natural diet in the wild?
