Use of dietary rosemary ( Rosmarinus officinalis L.) extract as a growth promotor and immunostimulant in common carp

Abstract: This study aimed to investigate the effects of rosemary leaf extract (Rosmarinus officinalis L.) on growth, haematological parameters, immunological profile and body composition in common carp (20.35 ± 0.37 g). The fish (n = 240) were fed with 0.0%, 0.25%, 0.5% and 1% of rosemary extract in 12 aquaria (300 L) with three replicates (each with 30 fish) for 60 days. At the end of the trial, final weight, WG, SGR, FCR and CF levels were significantly higher in a dose-dependent manner in the groups fed the diet con… Show more

“…To measure the growth indices, fish were anaesthetised by 0.3 ml/L of 2‐phenoxyethanol and then fish biomass in every farm were measured. The feed utilization and growth parameters including weight specific growth ratio (SGR), gain (WG), relative growth rate (RGR) and feed conversion ratio (FCR) were calculated for any treatment as follows (Chelemal Dezfoulnejad & Molayemraftar, 2021; Mohammadi et al, 2021):SGR0.25em)(%body weight/daysgoodbreak=][)(Ln0.25emWFgoodbreak−Ln0.25emWI/tgoodbreak×100WG0.25em)(%goodbreak=][)(WFWI/WIgoodbreak×100RGRgoodbreak=][W0.25em)(g/IBW0.25em)(ggoodbreak×100FCRgoodbreak=feed given0.25em)(g/weight gain0.25em)(gTime0.25em)(daysgoodbreak=t,initial body weightgoodbreak=WI,and final body weight0.25em)(ggoodbreak=WF.…”

“…Blood samples (5 sh per replicate, a total of 15 sh per treatment) were withdrawn from the caudal vein by a 2.5 ml sterile syringe and used to obtain serum. Then, the blood samples were kept at ambient temperature to clot and afterward centrifuged (3000 g for 10 min at a temperature of 4°C) for serum separation (Molayemraftar et al, 2021). Afterward, all the samples were stored at -80°C until analysis.…”

“…Plant extracts achieve a successful way in the aquaculture industry as dietary supplements in promoting growth and immunity, and against NPs toxicity [20]. Specifically, the plant-based NPs are characterized by their porous nature and easy penetration efficacy to fish cells boosting the immune-antioxidant status [21,22].…”
