“…Bransden et al [3] reported that the replacement of fish meal by dehulled lupin meal or hydrolysed poultry feather meal had no effect on immune function in Atlantic salmon Salmo salar L. However, an effect of dietary inclusion level of soybean meal on immunological parameters of Atlantic salmon was observed [4]. Similar results were reported in rainbow trout Oncorhynchus mykiss that serological and non-specific defense mechanisms increased when fed with soybean based diets compared to the fish meal based control diets [5]. In channel catfish Ictalurus punctatus, immune parameters including total cell count, red blood cell count and hemoglobin content were significantly affected by the interaction between dietary levels of cottonseed (replacing soybean meal in diet) and iron supplementation [6].…”

“…Early studies report an association between alternative protein diets and decreased fish growth (60)(61)(62), likely in response to intestinal inflammation brought about by dietary antinutritional factors (38,60). Subsequent research has demonstrated improved performance with newer plant-based diet formulations (7,10,63) with reduced antinutritional factors (64).…”

h As global aquaculture fish production continues to expand, an improved understanding of how environmental factors interact in fish health and production is needed. Significant advances have been made toward economical alternatives to costly fishmealbased diets, such as grain-based formulations, and toward defining the effect of rearing density on fish health and production. Little research, however, has examined the effects of fishmeal-and grain-based diets in combination with alterations in rearing density. Moreover, it is unknown whether interactions between rearing density and diet impact the composition of the fish intestinal microbiota, which might in turn impact fish health and production. We fed aquacultured adult rainbow trout (Oncorhynchus mykiss) fishmeal-or grain-based diets, reared them under high-or low-density conditions for 10 months in a single aquaculture facility, and evaluated individual fish growth, production, fin indices, and intestinal microbiota composition using 16S rRNA gene sequencing. We found that the intestinal microbiotas were dominated by a shared core microbiota consisting of 52 bacterial lineages observed across all individuals, diets, and rearing densities. Variations in diet and rearing density resulted in only minor changes in intestinal microbiota composition despite significant effects of these variables on fish growth, performance, fillet quality, and welfare. Significant interactions between diet and rearing density were observed only in evaluations of fin indices and the relative abundance of the bacterial genus Staphylococcus. These results demonstrate that aquacultured rainbow trout can achieve remarkable consistency in intestinal microbiota composition and suggest the possibility of developing novel aquaculture strategies without overtly altering intestinal microbiota composition.

“…Like whey proteins, soy and casein enhance the immune system function 21,22 . Soy protein contains some phytochemicals, such as isoflavones, which influence the signal transduction process of macrophages and cytotoxic T lymphocytes, thus influencing both non-specific and specific immune response 23 . Apart from dietary whey proteins, soy proteins and casein proteins can enhance immune response.…”

Dietary proteins have been reported to be beneficial for lipid metabolism, tissue growth, development, and repair, as well as immune response. The interactions of dietary proteins and their digested products may regulate the physiology and metabolism of the gastrointestinal tract. However, proteins are largely digested before reaching the large intestine. The present study investigated the use of the non-dietary protein, silk sericin, in rats. Rats were fed either with casein or sericin proteins. Their body weight, food consumption, and complete blood count were measured. The results showed that during the experimental periods, rats fed with casein and sericin diets had no significant changes on body weight, food consumption, or complete blood count. Sericin-fed rats had a significantly decreased CD8a and CD80 positive cells when compared with standard casein protein.In conclusion, dietary proteins may have a differential impact on the leukocyte profile. The mechanisms underlying these changes are not clear but they might be due to the different amino acid compositions of the proteins studied.
