“…Lysozyme is one of the most well-known serum lytic enzymes that work in the lysis of the peptidoglycan layer of bacteria (Mokhtar et al, 2023). The increment in the level of lysozyme in this work can be related to the improvement of its producing sources (i.e., neutrophils and monocytes) a hypothesis that was documented in several studies (Niazi et al, 2023;. The complement system is responsible for the connection between innate and adaptive immune responses.…”

“…Besides, Pontastacus leptodactylus (narrow-clawed crayfish) exhibited a LAB count higher than the control group, when fed by dietary supplementation of OAB (organic acid blend; Na-acetate, Na-butyrate, Na-lactate, and Na-propionate) (Safari et al, 2021). Based on documented evidence, modulating gut microbiota towards LAB strongly affects the activity of digestive enzymes (Niazi et al, 2023;Hoseini et al, 2022). In this study, dietary administration of LA+SA significantly increased the activity of protease and amylase enzymes.…”

“…Then, they were anesthetized with eugenol (100 mg/L) and infected through intraperitoneal injection (0.1 mL of the bacterium suspension). In this study, bacterial suspension was prepared at a concentration of 1 × 10 7 cells/mL using the method described by Niazi et al (2023). The selection of the dose in this study was carried out based on the concentration of Y. ruckeri (KC291153) employed in rainbow trout in recent studies (Naderi Farsani et al, 2021;Oroji et al, 2021;Darvishi et al, 2022;Niazi et al, 2023).…”

The current study was carried out to explore the effects of lactofeed (LA) as a multi-strain probiotic and succinic acid (SA) on growth variables, gut lactic acid bacteria count, digestive enzymes, innate immune responses, antioxidant capacity, and resistance against Yersinia ruckeri in rainbow trout juvenile (Oncorhynchus mykiss). Three hundred sixty healthy rainbow trout juveniles (13.21 ± 0.41 g) were randomly divided into twelve tanks (300 L) as four experimental groups. They were fed with basal diet (Control; BD), FT1: BD + 1 g/kg LA, FT2: BD + 5 g/kg SA, and FT3: BD + 1 g/kg LA + 5 g/kg SA for eight weeks. According to the results, final weight (FW), weight gain (WG), protein efficiency rate (PER), and feed conversion rate (FCR) revealed a remarkable discrepancy compared to the control group. In addition, dietary inclusion of LA (FT1 and FT3) significantly increased the specific growth rate (SGR). Dietary supplementation of LA+SA (FT3) remarkably improved total bacteria count (TBC) and amylase activity compared to the un-supplemented group. Gut lactic acid bacteria (LAB) count and digestive protease activity in all supplemented fish were remarkably higher than in un-supplemented gruop. Blood immunological factors including white blood cell (WBC) count, total immunoglobulin content (Ig), and the activity of lysozyme (LYZ), alternative complement pathway (ACH50), and acid phosphatase (ACP) were significantly enhanced in the supplemented groups. Neutrophil (NEU) count, skin mucus Ig and hepatic glutathione peroxidase (GPX) increased in SA (FT2 and FT3) treatments. In addition, monocyte (MON) count and skin mucus LYZ activity significantly elevated following feeding with the FT3 diet. Other immunological parameters of skin mucus including protease activity, alkaline phosphatase (ALP) activity, and ACH50 activity, as well as hepatic superoxide dismutase (SOD) and catalase (CAT) activities increased in fish fed with diets containing LA and/or SA. malondialdehyde (MDA) value was remarkably decreased in all supplemented rainbow trout compared to the fish fed with BD. Disease resistance against Y. ruckeri in fish fed with supplemented diets significantly improved with respect to the results obtained in the control specimens. Overall, dietary LA+SA supplementation was beneficial to improve growth performance, gut LAB count, digestive enzyme activities, innate immune responses, antioxidant capacity, and disease resistance in rainbow trout. According to these findings, 1 g/kg LA + 5 g/kg SA is suggested for adding to rainbow trout diet.

“…Employing biostimulants with capabilities such as high availability, low cost, safety, and antibacterial effects is one of the top options for boosting the growth and immune function of the hosts [12]. In general, the physiological activities of animals can be affected by intestinal microbial communities [13].…”

Tartaric acid (TA) is an organic acid whose properties in aquaculture have not yet been comprehensively studied. In the current research, the effect of dietary TA on growth indices, gut microbiota, the level of digestive enzymes, antioxidant and immunological markers, and survival rate following immersion challenge with Vibrio parahaemolyticus (14 days) in Litopenaeus vannamei were investigated. To achieve this, 600 shrimp (3.26 ± 0.05 g) were tested with pellets supplemented with five distinct concentrations of TA including 0 (TA0), 2.5 (TA2.5), 5 (TA5), 7.5 (TA7.5), and 10 g/kg (TA10) for 56 days. The results showed that the growth performance, feed utilization, gut lactic acid bacteria (LAB) count, and activity of digestive enzymes were markedly elevated in the groups receiving diets incorporated with 5 and 7.5 g/kg of TA. The highest total hemocyte count (THC), hyaline cell (HC), and semi-granular cell (SGC) counts were detected in shrimp fed with the TA7.5 diet. Hemolymph immune responses including LYZ (lysozyme), alkaline phosphatase (AKP), acid phosphatase (ACP), and phenol oxidase (PO) activities were significantly enhanced in all TA-treated groups. Dietary TA7.5 significantly boosted all antioxidant enzymes. In addition, malondialdehyde (MDA) content illustrated a significant decrease in shrimp fed with diets supplemented with 2.5–10 g/kg TA when compared with specimens fed with TA0. The survival rate following the immersion challenge with Vibrio parahaemolyticus markedly increased in all shrimp treated with 2.5–10 g/kg TA compared to TA0, irrespective of the dosage. However, the dietary inclusion of TA7.5 resulted in the highest survival rate. Based on the outcomes, dietary TA, especially at the concentration of 7.5 g/kg, is proposed to promote the growth performance and immunological indicators of L. vannamei.
