Antioxidant defence system based oxidative stress mitigation through dietary jamun tree leaf in experimentally infected snubnose pompano, Trachinotus blochii

Herbal extracts modulate growth, immune responses and resistance to Aeromonas hydrophila infection in GIFT tilapia ( Oreochromis niloticus )

“…The immunological parameter, RBT, showed an increased level in GIFT tilapia fed the JLE diet. This is in agreement with the earlier findings reported that RBT activity has increased after challenged with V. parahaemolyticus in Trachinotus blochii fed the jamun leaf‐supplemented diet at the inclusion level of 10 g/kg (Prabu et al, 2021). Also, Talpur et al, 2013 reported that ginger supplemented in the diet of Asian sea bass exhibited higher level of RBT and resistance to bacterial pathogenic infection such as Vibrio harveyi .…”

“…Among the herbal extracts supplemented diets, significant improvements in growth performance of GIFT tilapia were achieved by the dietary supplementation of jamun leaf extract at10 g/kg. Similarly, Prabu et al, 2021 reported growth‐promoting effect with jamun leaf‐supplemented diet at 10 g/kg in Snubnose pompano. The same researcher (Prabu et al, 2018) has reported higher growth response in Pacific white shrimp, L. vannamei fed the jamun leaf incorporated diet (10 g/kg).…”

“…Jamun leaf is one of the essential therapeutic plants which cure quite a lot of infectious diseases in folklore medicine, and it can be used as an immunomodulator in aqua feed to inhibit bacterial pathogenic infection (Madani et al, 2021. and Prabu et al, 2021). It possesses several secondary metabolites viz., anthocyanin, alkaloids, quercetin, acylated flavonol glycosides, myricetin, tannin, galloyl carboxylase, terpenoids, kaempferol and ellagic acid (Ayyanar & Subash‐Babu, 2012).…”

“…The pleasant odour in the aqua diet enhances daily feed intake and thus paves the way for stimulating the growth of fish. Jamun leaf extracted compounds supplemented in the diet of Litopenaeus vannamei (Prabu et al 2018) and Trachinotus blochii (Prabu et al, 2021) resulted in better growth, SGR, FCR, oxidative stress response, enhanced innate immune responses and higher percentage of survival after challenge with infectious pathogens. Avaram senna ( Cassia auriculata ) is a medicinal plant that possesses bioactive peptide compounds such as saponin, tannin, terpenoids, flavonoids, cardiac glycosides and steroids.…”

Enzymological, Histological and Serum Biomarkers Responses of Snubnose Pompano on Complete Replacement of Fishmeal Using Cottonseed Meal Supplemented With Lysine and Methionine in the Diet

“…Activities of the metabolic enzymes such as AST, ALT and ALP are the indicators of the metabolic processes and function of liver (Prabu et al 2021). In the current study, the activities of AST, ALT and ALP in the FM replaced with CSM groups were found slightly lower than the shes fed with control diet without cottonseed meal (0CSM).…”
