“…In our study, there was a significant increase in the LAB count isolated from the gut of groups fed on NaDF‐supplemented diets compared with the control group. In line with the results of the present study, other studies also reported that the abundance of pathogenic bacteria (e.g., Vibrio , Acinetobacter ) decreased, while intestinal beneficial bacteria population such as LAB were increased in different farmed aquatic species fed diet supplemented with OA such as whiteleg shrimp (Adams & Boopathy, ; He et al, ; da Silva et al, , ), Nile tilapia (Elala & Ragaa, ), loach Paramisgurnus dabryanus (Gao et al, ) and turbot ( Scophthalamus maximus L, Dai et al, ).…”

This study was conducted to evaluate the effects of dietary sodium diformate (NaDF) on growth performance, gut microflora, digestive enzyme activities and immune response parameters of Asian sea bass (Lates calcarifer) juveniles. Fish with initial weight of 12.5 ± 0.4 g were fed with five experimental diets contained 0.0 (control), 5, 10.0, 15.0 and 20 g NaDF kg −1 in triplicate for 6 weeks. Fish fed diet containing 5 g NaDF kg −1 had significantly the highest final body weight and feed intake among different treatments. The gut total viable bacterial counts gradually decreased with increasing dietary NaDF level. Specific activity of chymotrypsin improved in fish fed diets administered with NaDF compared to the control group. Fish fed 5 g NaDF kg −1 diet showed the highest serum lysozyme level among different treatments. The serum classical pathway activity of complement showed higher level in fish fed diets contained 5 and 10 g NaDF kg −1 than other groups. According to break-point regression method analysis, the optimum inclusion of dietary NaDF in L. calcarifer juveniles was estimated between 4.6 and 5.1 g/kg, when specific growth rate and feed conversion ratio were plotted against dietary NaDF levels.

“…It is considered that decrease in serum activities of enzymes in present research shows protective effect of trans‐cinnamic acid against tissue damage induced by the biooxidation (caused by reactive oxygen species) because it is revealed that trans‐cinnamic acid induces SOD in the present study. Similarly, earlier studies showed that the serum SOD or CAT activities provided an increase when fish were fed with caffeic acid (Yilmaz, ), fulvic acid (Gao et al, ) and citric acid (Zhang et al, ).…”

Dietary trans‐cinnamic acid application for rainbow trout (Oncorhynchus mykiss): II. Effect on antioxidant status, digestive enzyme, blood biochemistry and liver antioxidant gene expression responses

et al. 2019

The present study investigated the effects of dietary trans‐cinnamic acid (TrCin) on growth performance, biochemical composition, fatty acid composition, blood biochemistry, antioxidant status, digestive enzyme and liver antioxidant gene (EF1α, SOD1, SOD2, CAT, GPX1, GPX4, GR and GST) expression responses of rainbow trout, Oncorhynchus mykiss. Five experimental groups of fish with mean weights of 17.49 ± 0.08 g were used in the study; four of them were fed with TrCin‐supplemented diets (0.25 g/kg TrCin25, 0.50 g/kg TrCin50, 0.75 g/kg TrCin75 and 1.50 g/kg TrCin150), whereas an additive‐free basal diet served as the control (Cntr). At the end of the 60‐day feeding trial, the growth performance, biochemical composition and fatty acid composition were similar for all experimental groups. A decrease was observed in intestinal and stomach pH, serum triglyceride and AST, ALT, LDH and ALP levels in fish fed with especially 0.50 g/kg TrCin‐supplemented diet. Moreover, dietary TrCin especially at 0.50 g/kg incorporation level significantly increased the serum SOD and liver SOD2, CAT, GST, GPX1, GPX4 and GR gene expression responses. As a conclusion, feeding rainbow trout for a period of 60 days with a diet containing 0.50 g/kg TrCin might be sufficiently enough to improve the levels of antioxidant enzymes and health status in fish.

“…Moreover, Abdel‐Wahab, El‐Refaee, and Ammar () found higher survival (87%) in the common carp ( Cyprinus carpio ) fed 1% humic acid and challenged with Aeromonas hydrophila (0.5 x × 10 8 CFU/ml) as compared to the control group (54%) fed a diet without humic acid, representing 33% of net survival. It is interesting that in unchallenged Paramisgurnus dabryanus with pathogenic bacteria, survival rate does not seem to be affected by dietary FA (Gao et al, ); however, those organisms fed FA at 1.5% had less abundant common pathogenic bacteria (i.e., Serratia , Acinetobacter , Aeromonas and Edwardsiella ) and more abundant beneficial bacteria (i.e., Lactobacillus spp.) in the intestine.…”

Dietary fulvic acid effects on survival and expression of immune-related genes inLitopenaeus vannameichallenged withVibrio parahaemolyticus

The effects of fulvic acid (FA) on survival and immune-related gene expression were investigated in Litopenaeus vannamei challenged with Vibrio parahaemolyticus by immersion. Shrimp were fed with different dietary FA concentrations (1, 2, 4 and 6 g/kg feed) for 20 days (first bioassay) or 8 days (second bioassay, 2 g/kg feed of FA added every 2 days) and then challenged with V. parahaemolyticus. In a third bioassay, the expression of three immune-related genes (translationally controlled tumour protein [TCTP], superoxide dismutase [SOD] and heat-shock protein 70[HSP70]) in haemocytes or hepatopancreas of experimental shrimp was measured by real-time quantitative PCR at 0, 6, 12, 24, 48, 72 and 96 hr after FA (2 g/kg feed) administration. Fulvic acid increased survival at a concentration of 2 g/kg feed supplied every two days. Interestingly, TCTP gene expression was upregulated, whereas gene expression of SOD and HSP70 was downregulated. In conclusion, dietary fulvic acid improves survival in white shrimp challenged with V. parahaemolyticus and modulates the immune response. Therefore, FA merits further evaluation as prophylactic treatment in commercial shrimp farms. K E Y W O R D SAHPND, fulvic acid, gene expression, Litopenaeus vannamei, Vibrio parahaemolyticus
